The Uberman's Sleep Schedule...
If curious, I am a college student who found himself doing too many credits and needing more time in order to survive. I've been doing the Everyman sleep schedule for over a year now , and a polyphasic sleep schedule has really been a life-changer for me. To preface, I can't recommend it now because I have had many of my friends try the same thing and ultimately crash and just get really sick or unable to do it. Also I'm not sure if it works for some people and doesn't for others. There aren't many confirmed things at all regarding Polyphasic sleep schedules. For myself though it has been completely beneficial. I feel more awake than I ever have in my life. I have enough time to work-out in the morning, cook great breakfasts, do some casual reading, while still accomplishing all the homework, study, and other work that needs to be done. I naturally found myself falling into a really healthy lifestyle and even started to just want to eat healthy as well. Somewhat of a ramble here but in short, it has worked out great for me. I feel rested, more intelligent, and more healthy; but I know that the opposite has happened for many other people. Not much is known about it.[Here] is a good explanation to the different sleep cycles you can have and why you might do them.
After a woman gives birth and the organs fall back into place, is it possible for them to go back in the wrong way?
Prior to my wife's first pregnancy, she had continuous pains that we attributed to her stomach. The pains were sort of right around the bottom of the solar plexus. These pains went on for years. In 2006 she was pregnant and delivered in January 2007. Subsequent to her pregnancy the continuous pain simply went away. We have no idea the reason but we hypothesize that some organ or another was pushing on some nerve or another and now does not. Therefore, in that sense we believe that pregnancy can cause not a re-arrangement but a shifting of organs to some degree.
Why are general ed classes in college required regardless of your major?
College is not a vocational training program. It's meant to make sure you're a generally educated person.
In countries where people only use bidets and act disgusted by toilet paper, what do they use at concerts/festivals in port-a-johns?
Coming from someone that has never even seen a bidet IRL and really is totally unsure of how they even work, I just have one question After you pinch a loaf off in one, does it not blow it back up into your ass with the stream of water that's meant to clean you off? Do you use a regular toilet, and then move to a bidet? I am very confused with the whole process.A Japanese friend of mine always brings a [portable bidet] when he is traveling abroad.
How are racing games able to show the time with an accuracy of 1/1,000 of a second when they run at only 60 FPS?
It's true the game might calculate movement/physics more often than once per frame. But not all do, and it doesn't need to. Say you're moving fast enough to travel 20 feet before the next frame, and the finish line is 0.5 feet away. You'll cross it in 1/40 of a frame's time. The game doesn't need to calculate your position 40 times each frame to figure this out, it just needs to keep track of your position relative to the finish line, and do this math when you are about to cross it .60 FPS is how many frames are rendered graphically per second. The game programming can potentially run many more times per second than that, not to mention external things like clocks. They can easily check the time at the start of the race and then when they calculate you cross the finish line - even if that is partway between the graphically rendering of visual frames - they can just take the time again, and then subtract the two.
- Why are all the bottoms of clouds have a flatness about them while the tops are very non uniform?
Air will cool at around 3.5 degrees per thousand feet. At some point rising air cools to it's dew point and clouds will form. Any continued upward movement will cause the puffy tops, but the base of the clouds can't exist below a certain altitude, hence flat bottoms.
What makes buying insurance rational?
My brother used to work in insurance. He told me that statistically, every person gets into a car accident once every 11 years. Now, of course, that's just statistics. Of course there are people who get into multiple accidents in the span of 11 years, and those who never get into an accident even in multiples of 11 years. It's a game of odds.
Why is it ten-folds more difficult to sing and play guitar at the same times as compared to just singing or playing guitar?
Have you ever tried listening to music while writing? For most people this causes the writing to take longer, and it's harder to focus. Same idea. It's just that multitasking is hard and you have to be able to focus on two things at once.
Do shipping companies just sit on packages if you choose a slow delivering speed?
The delivery guy literally sits on your package when you pick a lower dilivery speed. That's why when you get your package, it's all dented and disfigured.
Now that I am no longer a climate change skeptic, how do we get rid of all this Co2?
The other comments have great answers on how to reduce the amount of CO2 you cause, but I want to point out why that's more important right now than removing it. Think of atmospheric CO2 as water in a big bathtub. Lots of us are little spouts adding water, and there's a drain way at the bottom. It's filling up because all of us are pouring in more water than the drain can let out. Soon it will overflow and we'll have a big mess. You're asking how to make the drain bigger. That's a good question but it's hard to make it bigger because it's hard to get at and expensive to change . But the goal isn't really to drain the tub. It's to stop it from overflowing and then to get the bath down to the right level for bathing in. We can do that by making the drain bigger, or we can do it by adding less water. You have a lot more control over the CO2 and other gasses you cause to be emitted than you do the amount of CO2 that leaves the atmosphere. The amount of CO2 something or someone causes to be emitted is their carbon footprint, but we also care about other gasses like methane and CFCs that also fill the bathtub. A really easy but really powerful first step is to eat less meat, particularly beef. Cattle use something like 4 times the food to make the same amount of meat that a chicken can, and they put out a lot of methane too, which is much worse than CO2. If you go from eating beef daily to only once a week, you'll have a big impact. You'll save money too!
Why don't we like the taste of everything that's edible?
I do like everything that's edible, and trust me, you would too if you didn't have such ridiculous luxuries
Why is this test able to predict your answer
Fuck, it got me. I thought red hammer was unique. Next time I'll choose turquoise needle-nose pliers.Nope, blue hammer. It might be that I already knew this trick so I came preparedPurple Sledgehammer for me. As to how? Statistics. The math part is a red herring. Ask people to think of a color: Most people will say red. Ask people to think of a tool. Most people will think of a hammer.I read the comments here before actually doing it so I knew what it was about, so I can't accurately say what I would have said.i said "red hammer" in my head and though \'well that's stupid\' so i said blue screwdriver', "I said blue hammer. So I guess I'm half abnormal!
Why do some numbers in a list end in st like 1st, and others end in nd and rd like, 2nd, and 3rd?
best".2. "Second" is a word that means "next" or "following".3. "Third" is an example of "metathesis", which is when letters are swapped inside a word. The word was originally "thridda" , but the "r" and "i" became swapped over. The "d" is related phonetically to the more usual "-th" ending. For a long time, "third" and "thrid" were both in use, but "thrid" died out some time after the 16th century leaving us with the new form.4. From "fourth" onwards things settle down a lot. Old English used the suffix "-tha" or "-thu" to make the ordinal numbers, and we simply no longer bother with the vowelsWhen considering the development of the numeral system, remember that many people in the middle ages during the development of the English language were effectively mathematically illiterate. With no formal education system and no reason to count to large numbers, the common names for small digits developed fairly randomly in each language. That's why our base-ten numbers have unique names to twelve for no reason and then suddenly shift to a different convention, and that's why 1st, 2nd, and 3rd have unique suffixes before shifting to a standard. There's no real grammatical reason why "oneth, twoth, threeth" *couldn't* work, but "first, second, third" had already been borrowed from German, Latin, and Dutch respectively and cemented in the common speech before anyone tried to standardize numerals.
If black is just our way of perceiving a lack of light being reflected off of a surface, how can we have "shiny black" such as oil, black plastic and asphalt?
When you see something, you're really seeing light that has bounced off of it. Some surfaces reflect light differently. Rough surfaces tend to bounce light in many directions. They'll usually appear to be the same color no matter what your viewing angle is. Wood, brick, and paint are rough surfaces. Smooth surfaces tend to bounce light in only one direction. You'll see the highlights where light is bouncing directly at you. Water, mirrors, and oil are smooth surfaces.
Genetics are easy to understand when you have a few fixed outcomes like eye color. How do they work when it is something like height?
Don't over simplify eye color either, saying the colors one eyes can be are hazel, green, blue and brown would be like saying the height one can be is short, average and tall. Eye color and height both are determined by a good number of genes that we have already identified, but also likely very many others that we have not. The human genome has not been completely unraveled, but we are learning more as we continue to research. To answer your question, we understand the variables that go into human height potential about as well as we understand those for eye color. They seem easy to understand at the macroscopic level because two parents with brown eyes quite often have brown eyed children, creating a kind of pattern we can recognize, but it is important to understand that these patterns are what we use to predict eye color, not some understanding of activated genes. But for the very reason you stated, there being a much more apparent lack of predictability with height, you would be had pressed to find a reputable geneticist willing to predict a patients height potential within a margin of less that maybe 6 inches.
How is the average life of long-life products calculated? Some LED bulbs have a 24.8 year life. That seems unusually specific for a product that hasn't existed that long.
The Philips bulb that won the Department of Energy LED efficiency prize back in 2011 have been run continuously for over 40,000 hours with an average of just 5% luminous loss. Of the 31 bulbs being tested, not one has failed. _URL_3_ I have a number of these bulbs and they are still the best bulbs I've found by a wide margin. Too bad they were discontinued.Engineers should know this. HALT - highly accelerated lifecycle testing. Buncha extreme electrical and environmental test conducted concurrently. _URL_4_There is a complex mathematical formula that correlates the failure rate of electronic components when tested under high temperature conditions to their expected failure rate and MTBF/MTTF in real life. Even at zero failure over the course of the test, the formula produces a non-zero estimated result. But the numbers on LED bulbs in particular probably also have some average usage assumptions and marketing factored in.Just wanna point out that LEDs aren't new at all. They have existed for decades. The little lights on old computers, TVs and eletronics in general are LEDs, you've most likely seen them. They just weren't used as a lighting source, only as signals.
What is the difference between the cyclical climate change seen during the Ice Age and the climate change we see today?
Not positive about back then. Today we burn a ton of carbon based fuels like gasoline, natural gas, diesel and every other fuel which, when burned, release CO2 gas into the atmosphere. The CO2 doesn't block the visible light coming from the sun so the Earth warms up like normal, but at night when the Earth tries to cool down, it does so by radiating in infrared. The CO2 in the atmosphere partially blocks the infrared making it so not as much heat can escape. The heat has nowhere to go except for being stored by the Earth thus warming it up. The fuel that's in the ground natural decomposes and makes CO2 but the CO2 we produce is a few orders of magnitude higher and the Earth can't get rid of it fast enough.
Why does it snow at sea level in America, but not at sea level in Australia?
Whether it snows or not doesn't depend where you are. It depends on the temperature. In NYC the temperature is below 32 degrees F sometimes. So it snows. In Australia, it may be below 32 degrees F but there is no precipitation above you or you area never reaches 32 degrees F. As you getting higher and higher into the atmosphere, it gets colder and colder. That's why most really tall mountains have snow on them, a) the temp around them at this altitude is below 32 and b) they are physically in the clouds, clouds are just water vapor. That water vapor turns into snow or ice
Why does the tissue on the inside of your cheek heal/regenerate so quickly?
There's one reason that I didn't see mentioned here. It HAS to. It's got a lot of things going for it that help it heal quickly, but when you get right down to it, cuts, abrasions, and burns in your mouth have to heal quickly or else they'd become really nasty festering wounds. Mouths are really nasty biological cesspools, and if you get an injury there, you're a lot better off if the skin cells in there are actually programmed to react to damage with superspeed repairs.
what exactly is "pi"?
Pi is the ratio of the circumference of a circle to its diameter. It's a mathematical constant you'll be using a lot if you're doing geometry with round things or angles. Angles are everywhere.
Why are aircraft carriers uncommon in most militaries
They are expensive. The Nimitz class carrier costs about $4,500,000,000 a piece. Most nations don't spend close to the US defense budget. Hell most countries GDPs are smaller than just our defense budget. The US is also a bit unique in that we are sort of alone on our continent, most of the nations we would need a presence near are across the Atlantic and thus the US needs a carriers more than almost all Europe / Asia nations.
Why is it so easy to confuse left and right, but seems impossible to confuse up and down.
Up = Sky. Down = Ground. And that never really changes—at least not unless you're doing helicopter tricks. However, taking three lefts is the same thing as taking a right—it's always way more contextual to where you currently are in space. Suppose we walked down hallways in one direction our entire lives and the black wall was always left and the white wall was always right—I don't think we'd ever get that confused either.Gravity. Ground vs sky. . Axis of symmetry of the human body we are symmetrical left to right but completely asymmetrical up to down. There is a left hand and a right hand. There is not a top head and a bottom head. [no penis jokes]
Why is music/lyrics so much easier to memorize than other things?
I am a professional jazz musician and I, for the life of me, cannot remember ANY lyrics. Sometimes I can sing along to things I have heard a million times. But I can't even recite lyrics to Nirvana songs, which were my first musical obsession. My connection with music is melody, harmony, and rhythm. But I also realize I am in the minority. The average non-musician nowadays is more concerned with lyrical content than melodic content.
Besides the initial excitement about a new planet, what is the appeal of Proxima B if it would take so absurdly long to get there to study it?
It's the least absurdly far away place possible, just about. Every other place is more absurdly far away. If the alternative is to get somewhere in 50 years or 10,000 years, 50 years is obviously better.
Why is the dirt taken out of the hole rarely enough to fill it back?
Maybe some of it flies away with the wind since its now loose and manueverable. In addition some dirt will just resettle on top of the ground nearby and you don't notice since it evenly displaces itself. No science behind what I'm saying just taking a guess. Source: I sometimes dig holes in my yard when I need to.
With 48 hours of video uploaded per minute, how does YouTube survive?
I would guess massive amounts of storage, probably homebrewed solutions for it like the google servers to keep it cheap, likely running on their own file system, and LOTS of deduplication. I can't imagine running a service like YouTube without dedup._URL_1_ Here is a link that talks about how YouTube is able to scale. Storage is cheap and easy to buy more space to add on, they have a lot of servers which let a lot of people connect and so some can handle uploads while others let people view videos', "Pre google buyout this is a good link: _URL_2_ Fun fact: it started out on a single server. Lols But now google owns it. Lets assume for a minute that google has 2 million servers. Those are all running google file system. This roughly makes all those servers a big drive to be used. So what kinda hard drives is google using? Same shit you can get. its cheap. At their scale it acts fact with the right CDN, caching, other google magic. _URL_3_ 2tb per server. * 2 million servers = 4 million terabytes. Or 3906 PetaBytes. Without knowing any of their details operationally I'd guess that media, video and photos, are their largest data hogs by volume. tl:dr lucy lu danced, tigers cried
How does only part of the moon show up when its not full?
The other answers are good, so I won't repeat them, but I will point out something kind of cool. When the Earth is directly between the moon and the sun, then if you think about it that means that the part of the moon facing the Earth is also facing the sun. So whenever we're directly between the sun and the moon, then the moon must be full. Now, an eclipse happens when the Earth casts a shadow on the moon. For the Earth to cast a shadow on the moon, the Earth must be between the sun and the moon, and we just figured out earlier that this implies that it's a full moon right now. Therefore, all lunar eclipses must happen when there's a full moon!
Why Does Your Breath Smell Bad When You Don't Eat For A Long Time?
As well as the reasons that /u/ChuffChuffs and /u/kodack10 mentioned, the stages before eating food, thinking about it, smelling it, seeing it, cooking it etc all trigger your parasympathetic nervous system to produce and secrete more saliva into your mouth. This is further increased while actually eating. This means that your mouth will have much more saliva in it right after eating, and saliva has microbial properties that will kill some of the odor producing bacteria, particularly on the back of your tongue. This is why brushing the back of your tongue is recommended to help with bad breath. If you haven't eaten for a long time, or have spent a long time breathing through your mouth , the air dries out the saliva in your mouth, so more bacteria, so more bad smells.
How do reddit moderators pick and choose which ELI5 post to remove? Theoretically google could be used for every question on the whole subreddit.
We remove as many of the posts as we can that don't follow the rules for the sub. We're a small mod team so do what we can, a lot get missed.Some posts have been done literally dozens of times. Like "why does chewing mint gum make my mouth cold?" and "why do people like music?"
I recently learned that the Mars atmosphere is 95% CO2. Since CO2 is a greenhouse gas, was isn't the planet much warmer?
Because 95% of barely anything won't make much difference. Mars' atmosphere is extremely thin. It has 0.6% of the surface air pressure of earth. It is about 100 times thinner than earth's atmosphere. The warming as a result of a greenhouse gas only works if the gas interacts with the bouncing light to keep the energy on the planet. There's so little atomosphere that this effect barely contributes to the surface temperature of Mars at all.
how certain are our scientists that we won't accidentally bring something back from Mars / asteroid / etc that would potentially be hazardous to our planet?
Well, anything that evolved to live somewhere else isn't going to be suitable in the slightest for the living conditions here. If we implanted Ebola on Mercury, Europa, or literally anywhere else it wouldn't be able to do shit.
How are stores able to make a profit on Black Friday if they mark everything down so much?
A lot of products are marked up a great deal. It's not unusual for stores to price items 100% higher than what hey get it for , many electronic manufactures make products specially for Black Friday and Chistmas time, using much cheaper parts, you can tell because the model numbers are different than the regular versions. All that being said, stores may price items at or below cost in hopes consumers by items that have been marked up, and hope to make a profit.You can look it up, there are lots of "black Friday edition products". Items that are either reputed brand items with next to no quality or cheap no name products with a bit more features but next to no quality. Like the others have said, the main goal is to sell a few products with it to raise profits.
What are the negatives of putting nuclear waste on a rocket and launching into the sun?
It's a great idea if rockets were perfect. But one single rocket having a mishap would be a disaster. We would have to launch hundreds of rockets to get rid of all our waste on the planet. There's a high chance of some of them having problems. An explosion of a rocket in mid-air would spread radioactive material a long way away.I highly recommend checking out this documentary _URL_1_ about a project to secure nuclear waste underground. It seems people involved in its planning have really taken the time to well engineer a disposal site aimed to last 100,000; the length of time it takes for decay to render waste non toxic.It's horribly expensive, launching things into the sun hasn't been tried because it takes a fuckton of fuel, and if soemthign goes wrong during the rocket launch, you're looking at a nuclear disaster that makes Chernobyl look like a firecracker.The amount of waste we would create building and launching each rocket would be more waste than we fit on the rocket. And, it would be extremely expensiveIt costs $10k to but 1 Kg into orbit, so shooting something to the sun would cost an astronomical amount of money.
When does a "startup company" actually stop being referred to as one?
A startup is often defined as a company searching for a scalable, repeatable business plan. So I'd say that when a startup stops experimenting on product / go to market etc. and starts executing the plan, it is no longer a startup.
Why are pay bonuses taxed heavier than your regular wage?
Income is generally taxed more as you earn more. For example, the first $15,000 might have no tax, $15-40,000 might be at 10%, and above $40,000 might be at 20%. These are called tax brackets. Generally at the start of the year, your employer figures out your average tax and keeps that to give to the government directly. For example if you earn $30,000 you'd owe 5% on average, so you'd only get to take home $28,500. If you get a bonus, it could take you into a higher tax bracket, but even if it doesn't you'll still have to pay the full amount of tax for the top tax bracket, rather than the average. In my example, if you get a $10,000 bonus, you'd own 10% of that in tax, so you'd only get to take home $9,000. The end result is that you're still paying the same amount of tax as if you had been earned $40,000, but the tax isn't as nicely averaged over the entire year.It's important to remember that you're not paying your taxes every time you get a paycheck. Taxes are "withheld" from each paycheck and basically put in to a savings account to be paid on April 15th. When they calculate withholdings, they take the amount of any check and then multiply it by the number of pay periods in a year and calculate how much tax you "should" owe at the end of the year. If you get a large check with a bonus, the assumed yearly income is much larger, so you are taxed in a higher tax bracket. If the trend of higher paychecks doesn't continue, however, you would get a larger portion of that one big check refunded to you when you officially file your taxes for the year.
What it SRS, all the drama surrounding it, and why pretty much all of reddit hates it?
I frequent SRS so take this with a grain of salt. It could be a little biased. SRS mainly exists to find and point out posts that are deemed offensive or ignorant. Once posted, they are typically made fun of, etc. I can think of a few reasons why reddit doesn't like SRS: 1. It's a circle jerk. It evenly explicitly says that in the SRS rules. Therefore dissenting options are often mocked and quickly banned. There is very little discussion. r/srsdiscussion is a better place to talk about the issues. Most people view the subreddit as being unwilling to listen to dissenting opinion, but those are just the rules o the subreddit. 2. People don't like having there opinions thrown in their face . But generally people don't like people called out on their shit and SRS does this a lot. 3. A lot of the posts in SRS are offensive jokes and people perceive this as SRS having no sense of humor and wanting to censor reddit. If you want to find out more about SRS visit the subreddit and if you want to see why a lot of redditors don't like SRS I suppose you could visit r/antisrs. There's porobably more to all it, but this is a very succinct explanation.
How is porn still profitable?
Do sex products count as part of the porn industry? Like didlo's named after porn stores or blow up dolls?
Why do people care so much about kitchen cabinets, why do they cost so much, and what makes them out of date?
When you buy a new house, you want the parts inside to be good condition. Its not required or anything, but if you put $10k into your house before selling it, it can bring $20k more into the sales price .
Why do people wear helmets in autocross?
I ride motorbikes and would argue the same reasons for 4 wheeled motorsports as I would for 2 wheeled. A good, properly fitting and quality helmet will protect your head massively more than nothing at all. The seatbelts are very good at what they do but they don't hold your head still and you can still have your head move at some pretty extreme speeds when crashing which could result in a head injury or, more likely, a neck injury where a neckbrace would also help . In a high quality helmet you'll have a multiple layers under the hard exterior, the 2 softer inner layers probably do a majority of the work in cars, being the foamy material actually in contact with your head and the inner layer of polystyrene which is softer and has some ability to compact to cushion your head. Also, as I understand it, an airbag deploying has been described to me as someone hitting you in the face with a big exercise ball with absolutely no warning, a properly fitting helmet would take the brunt of this. My current helmet has a 120 degree field of vision so in a car I can still see both mirrors just moving my eyes and the vertical space doesn't hinder my vision out the windscreen at all
China has giant empty cities like Ordos that have been waiting for years for people to move in to. Why don't Syrian refugees go to the massive already built empty cities in China?
The Chinese government doesn't want foreigners living in China, especial those who believe in a higher authority. Muslims really top that list there on both counts.
What are "eye boogers" and how are they formed?
Also why do I no longer get them as an adult? I can't remember the last time I had them but as a child I had them practically every morning.I just call them sleep. like not anything else like sleep gloop or fukin sleep boogers. We just staright up call that gooey eye shit sleep.They're actually not naturally occurring, it's dried up ejaculate. Now who's ejaculating in your eyes, I can't say for sure but it's probably someone close to you like a roommate, brother, or social studies teacher.
What do protein supplement powders actually do for your body after working out (e.g. Whey Protein powders)? What benefits does it provide?
Use _URL_5_ . They are really the one-stop-shop for *all* of your supplement questions. Totally science based. You can search per supplement, or per health goal. For example 'Fat lossPower output' etc. Search Google for their book PDF too.
How is tungsten melted down if the torch that produces the heat and the crucible it sits in all melt at lower temperatures than the tungsten?
Others have answered about the crucible. As for the torch, you can have a flame hotter than the material of the torch, as the gas is constantly flowing out, so the actual flame is a bit away from the nozzle, and the heat is constantly blown away from the nozzle. For example, it's completely possible to use one acytelene torch to melt the nozzle of another torch, without the lit nozzle even getting very hot.A process used to form solid tungsten shapes is Chemical Vapor Deposition CVD. It has been used for many decades. So no melting is necessary. _URL_0_ This can be done at only a few hundred degrees C.
Lossless audio files. What's the point of having a 1000 kbps FLAC file that's 40 mb vs. a 320 kbps MP3 that's less than 10 mb?
In photography terms it's sort of like the difference between a JPG and a RAW file. Not sure if this helps, just how I see it.FLAC is lossless. All of the information that the computer could capture and reproduce is stored in the FLAC file. MP3 is lossy. The MP3 format discards a lot of sound that is supposed to be mostly out of the range of human perception, but for people who are really in to their audio quality there are noticable compression losses and artifacts.Some people think they can hear a difference. Maybe they can, I don't really know. Personally, I don't.
Can your body become addicted/dependent on a substance even if you have no idea what it is?
In the real world, it happens all the time. Many people are simply unaware of the dependence risks associated with relatively common medications: benzodiazapines, z-drugs , opioid pain medications, etc. The problem with your example is that one night of drinking/meth/cocaine isn't going to make you addicted. Dependence means that you need the drug to reach normal/equilibrium. That process doesn't happen overnight. With occasional use, you're looking more at the psychological side of drug use. You might crave a particular sensation. You might feel anxious or irritable and feel off or sense that something is missing.
Why does it cost over $2 million to make a single Family Guy or The Simpsons episode?
This is going to be buried but, here's my perspective: I run my own animation business and have collaborated on a Major Lazer episode for FXX. In short: it's a lot of fucking work. And, when it's not a lot of work, it's not making up your mind. A lot of these shows are writer first which means the board artists often have to stick exactly to what's being delivered. There's obviously wiggle room, but for the most part, showrunner and writer first. This isn't so bad, until they come up with an idea at the last minute. Often it's better, and it makes a lot of us struggle to turn the ship around on a dime and adjust. Imagine rotating an aircraft carrier, full of planes, because someone found a new direction. And you have to listen to that direction :) Figure it out! It's often expensive. People also cost money. LA is a union town, so, we have to cover things from pension to healthcare. Rates are high because the talent is amazing and doesn't come cheap. As shows continue to prosper that talent, rightfully, asks for more. And I'm not talking about a voice artist, I'm talking about just regular story artists, writers, timing directors and the army of people involved. Not making decisions until the last minute is also painful. Any animation studio will tell you how difficult it is to get approvals and be forced to wait until the very last minute. Screwing up pre-production and not knowing the direction you want to go in are major pitfalls. An ounce of prevention is a pound of cure is very true here. Hey, shameless plug, I made a video about this too It's mostly geared towards CG animation but at the end of the day, it is still a flat image that moves. :)
Do police really have speeding ticket quotas and if so how do they work?
No. Working 8 years in a big city department I've never been told to write tickets, get a certain number or anything of the sort. We enforce traffic violations as we see them, and most of the time we're busy with 911 service calls. Sometimes if we have complaints from citizens about more specific issues than we'll focus patrol on that area when we can but that comes from citizens, not supervisors. Tickets, arrests and other things are looked at if you're trying to get into a special unit but other than that there are no real incentives to writing more tickets. Some guys write them, some guys don't.
What does a 30% chance of rain actually mean?
It means that if you looked at 100 days with similar conditions, it would have rained on 30 of them. Plus or minus the forecaster's judgment.
Why did they remove baseball from the 2016 summer Olympics?
They were actually removed for 2012. The IOC has a limit on the number of sports that are permitted to be in a single Olympics. Occasionally, sports are removed and others are added. Removing the two sports of softball and baseball opened up two spots that were unfilled in 2012. However, this has enabled golf and rugby sevens to be added for Rio 2016. Baseball was dropped because it has a limited popularity outside of North America, the Caribbean, and the Far East. Additionally, Major League Baseball has never released their players to take part, meaning the competition isn't always the best. Softball is even less popular globally. Also, baseball requires a very oddly shaped stadium which can drive the cost of the Games up. While golf courses are also expensive to make, the public can utilize the course after the Games are done or an existing course can be used.
Why is it acceptable for celebrities to receive millions of dollars in salary while a CEO of a billion dollar company is often criticized for that?
Because people aren't rational - so many people won't even make that connection. Of course, it doesn't help that most people only notice the CEO when his company is doing something they don't like. The average person probably couldn't identity the CEOs of the vast majority of the big banks, or any other industry unless they are involved in a scandal.Actors receive lots of money because they bring in big money for the movies they work in. There is the perception that executives rarely benefit the companies they work for in a way that justifies their salaries, and that they often fail upwards - being rewarded for poor jobs. For example, recently announced presidential candidate Carly Fiorina was formerly the CEO of Hewlett-Packard, and did so poor of a job that she was forced to resign. But unlike you or me, who would get very little in a severance package for being fired, Fiorina got $20 million dollars. Twenty million US dollars *for being tossed out*. What sense does that make? Source: _URL_0_', "CEO pay has changed significantly in the past 50 years. Celebrity compensation, for all intents and purposes, hasn't. [The average ratio of CEO-to-average worker wages in the US has increased from 20:1 in 1965 to 273:1 in 2012.] That's really what people are reacting to. There have been movie stars for as long as there has been mass media. But CEOs making *hundreds* of times what the average worker of the company makes is a relatively new phenomenon that has particularly accelerated in the last 10-15 years.
How come cars don't automatically detect and tell what is wrong with them? Given all the technology we have today?
What bothers me is that you still have to go to some trouble to read the code yourself. Sure, you can get USB thingies or other tools from the internet. But many cars these days already have digital readouts for things like trip computers, mileage calculators, etc. Can't the code just be shown there? Most new car stereos have digital readouts to show what song is playing. Can't the code just show up on that digital readout? I just get the feeling that it's a racket set up by the repair shops.
How are photos colourised?
I'm a graphic designer, and did a lot of colorization back in the day when I was practicing Blending Modes. B/W pictures have two colors as the name tells, Black and White, but between them, there is an intensity level as a transition from Black to White. What the artist usually does is that he guesses pretty much all of the colors and then he selects the area he wants to colorize, let's say a car. The artist selects only the car body, then creates a new layer, and he applies the colors he see fit only in the selection . Now when he does, he plays around with the saturation of the color, and most importantly, the Blending Mode in Photoshop. What the Blending Mode offers is the application of the chosen color according to the intensity of the aforementioned shade and that gives the color a more natural feel with a gradient other than just a uniform shade of a color applied to the car.Is there an automatic way or software to do? Or is photoshop layer by layer is the only wayI made a video of myself colorizing Audrey Hepburn _URL_1_
the different road types: street, avenue, road, drive, parkway, highway, etc...
I don't know if it works everywhere, but in Poland avenue is when lanes in different directions are separated by something: a grass lane or a tram track or something like that. Otherwise, it's a road/street.
If a jury is supposed to not know the details of a trial ahead of time, how do they find jurors for high profile trials like the Boston bombing?
They find people like me. I just served as jury foreman for a local murder trial a few weeks ago where the victim was a well known and well liked member of the community. I am fairly new to the area and did not know him, and since I very much keep to myself, did not have any prior knowledge of the crime in question. I am not that rare, there are quite a few people who, for whatever reason, don't read the paper or watch the news.The only hard part can be finding them. I was part of a jury pool of over 125 people, it took a full day of questions to sort us out and create the jury. In a case like the Boston Bombing, that jury pool will be much larger, and take much longer to sort through. But eventually they will find enough people to get the job done. Also knowledge of the crime or parties to the crime is not the only criteria, they asked a lot of questions unrelated to that as well.
What stops democrats from registering as republicans en masse for the primary and voting for the weakest candidate, so as to give Obama an easy ride in November?
A few things. 1. Like others have mentioned, depending on which state you live in you may or may *not* be allowed to vote in a party's primary unless you've been a registered party member for some time. While it's easy to register to become a party member, even the slightest hurdle makes people less inclined to vote. 2. I know from first hand experience that many people find the notion of doing this incredibly offensive. For example: in 2000 I voted for McCain in Michigan's Republican primary, even though I had absolutely no intention of voting for him in the general election. When I told friends/family/etc. about this at the time, many accused me of doing something unethical/immoral. In other words? Many Americans take their vote very seriously. 3. Most years, some states' primaries count more than others'. If you're in one of the early primary states you're more likely to be aware of the primary because the media makes a huge deal about it. Therefore, those voters take their votes more seriously. If you're in one of the later primary states, usually the contest is over well before you have a chance to vote so nobody cares enough to vote, much less try and sabotage the opposition. 4. Finally, a lot of Democrats don't have the stomach to vote for one of these assholes, even if it is for a righteous cause. I do, however, and plan on voting Newt Gingrich if this contest lasts until February 28. I will, however, take a long hot shower after doing so.
Why is the g string on a guitar the one that tends to go out tune the most.
Have your guitars professionally set up, and you won't have strings going out of tune. Tighten the keys, put a little bit of Vaseline with graphite shavings from a pencil, mix up and put in the nut. That will stop slipping. So as long as your keys are tight, you should stay in tune. There's a lot of things you can do to your guitar to get it to perform better.
Why do presidents elect Supreme Court justices? Doesn't this defy the whole balance of the three branches of government?
The president nominates the Supreme Court justices. The senate must confirm the nominee. Once a justice is actually on the court, they cannot be removed unless impeached by congress, or if they resign, or if they die. So there are a lot of checks and balances and that is why President Obama's nominee is not going to be appointed. The senate refuses to even hold hearings on the nomination.
Why do we have to file taxes and pay the IRS money? Don't they already take money out of your paycheck for that very reason?
And why should we do our taxes every year, if they already know what they took and can tell you when you did your taxes wrong? The IRS fixed my mom's form and told her about it. What's the point of us doing it if they're going to do it anway? Sorry, asking on your question, but it's tax season and on my mind :)
Why have we not paved the deserts with solar panels yet?
There are two main reasons: 1. Solar panels aren't efficient enough for it to be cost-effective. 2. Deserts have ecosystems too. People don't usually think about all the things that live in the desert, but deserts aren't completely barren of life.
Why does California allow public/private water fountains and water-parks during a Drought State of Emergency?
You're really going to hate the town's, farms, and companies paying zero for their water.
Why are pencils shaped in a hexagon?
Why aren't chapsticks square/triangle/hexagon? Because that design would plummet sales by 80%.Hex or octa have the best shape as far as not wasting space. Bees use this shape with their honeycombDoes this belong here? isn't this more of an "explain because i'm to lazy to google this simple bit of trivia" thing?
Why is space debris during interstellar travel at 35,000 miles/second + not an issue?
It's partially the fact that space is empty. The other is that any given spaceship needs some form of shielding to travel at those speeds. These are split into two general categories, powered and unpowered. Skylab, for example, had [micrometeoroid shielding]. Powered is more theoretical right now but could take the form of gravitational shielding, where there is a gravitational wave wrapped around the craft.
Why would companies like Dominos prefer to sell me 3 entire one-topping pizzas for cheaper than one pizza with multiple toppings?
Usually I'd say it is because they have an abundance of common toppings and can sell cheaper. Using all toppings or less common ones cost.
What should I expect from my root canal?
I've had two root canals done and /u/nuclear1975 has described the process well, though I didn't have any 'singeing' of the root. As for the experience - for me it was fine. They inject analgesic into the gums and the roof of your mouth. That's not pleasant - it's never nice being stabbed with a needle - but once it takes effect, no more pain. *Do* let your dentist know if the analgesic isn't working. The drill is a little scary if you worry about it slipping, but trust your dentist. A root canal, particularly on a molar is probably a pretty easy thing to drill. Then they'll scrape out the root. This won't *hurt* but it does feel weird. Imagine someone scraping the inside of your tooth with a rough wire. It *feels* wrong, but it's actually fine. Remember that, and don't worry about it. The rest of the procedure is easy; cleaning up, filling, capping, etc.. The worst bit for me was when the pain relief starts to wear off. At this point you start to feel the tooth ache, and you wonder how bad it will get , how long it will last and if everything is ok. But it should be fine, so don't worry.They drill out the tooth and then excavate the root, usually this is done by using a small filament to ‘scoop’ out the remainder of the root. It’s then packed and filled. If there’s any infection around the root then they may drill it, clean it pack it and temporarily fill it whist you take a course of antibiotics. Then you go back after a week or three and the remove the filling take out the packing and re excavate anything that’s left. Oh yea I forgot they burn out or singe the root remains from memory. It sounds worse than it is, there will be copious amounts of pain relief and as the root is already dead there shouldn’t be too much of any sensation.
Why do television camera crews use very large cameras to film, but my go pro cam shoots HD and is smaller than my fist?
Note that sports cameras have deep optical zoom, meaning they're taking light from an enormous opening and routing a focused subset of it onto a sensor. GoPro has a high resolution sensor but the pro cameras are just grabbing and managing way more actual photons, before the sensor has even shown up.
how does GPS work by just asking a satellite what its time is?
GNSS don't use triangulation there is no angle to measure. GPS use trilateration. Your GPS already have a good idea what time it is with is own clock so when it receive the time from a satellite it can create a sphere around the GPS satellite of possible location based on the speed of light. With a second satellite your receiver can create a second sphere and now your possible location correspond to intersection of two sphere: a circle. Add a third satellite and a third sphere and your possible position is down to 2 points. One of which you can discard because it's in space. You now have your position on earth. But the time your receiver have is not as good as those of the GPS sat so your first guess as to when the satellite send the signal can be a little off. By adding a fourth satellites you can reduce this error and get a better position.
Why is the roman or ottoman empire not called the italian or turkish empire?
Italy's borders as we know them also didnt even exist at the time, and neither did Italy as a country.
What happened with the game Spore?
To put it simply, there were 5 different teams working on five seperate games with minimal communication between them. Near the end of the production cycle, the games were slapped together and it was mostly an incoherent mess. It's a prime example of a vision losing focus.There was a lot of discussion in this thread when the game came out: _URL_3_
How does Kim Jong-un keep his people from knowing what's going on in the real world?
When my husband came to China in the late '80s the Chinese he met were genuinely surprised to hear that the United States was not, after all, a land of poverty and deprivation as they had grown up believing. They were taught that however bad things might be in China, they had it much better than those poor Americans and other suffering capitalists throughout the world. Can't underestimate the power of propaganda and mind control in a truly closed country.
Why do you fall asleep much easier on the couch watching TV (or anywhere other than your normal sleeping place) than in your normally used bed?
When you fall asleep watching TV it's because at that moment you are tired enough to fall asleep, so you do easily. If later you try to force yourself to fall asleep even though you aren't as tired then, you will naturally have a harder time faling asleep. There are probably plenty of times when you are watching TV and don't fall asleep, and the reason is because you just aren't tired. But it's easy to see why the time you are most likely to fall asleep is when you are most tired, and if it happens to be in a relaxing place like in front of the TV, so be it.Not only that, think about it like this. When you are in bed, you have nothing to do and you cannot simply just lay there literally doing nothing, you have to think about shit. When laying on the couch, watching TV or a Movie, your brain is being used to relay the audio/visual of the Television and slowly exhausting it. I like to fall asleep while watching a movie and whenver i feel like sleeping, i simply turn my head so all i hear is the audio and my brain gets tired from simply that. Hope this helpswell first you must understand that what you describe is not universal behavior.
Why colonize the moon or Mars instead of inhospitable Earth locations?
We'll have to, eventually. The sun will literally engulf the Earth in ~4 billion years. But during that process, in about 1 billion years, the Sun will become so radiant that it will literally evaporate all of Earths oceans. As a species, our time on Earth is limited. Granted, that's in 1 billion years, which is a loong way away. So we have time. But it's inevitable that we need another planet to live on if we're to survive as a species.
Why do ISPs want to throttle Netflix?
Since Netflix can take up a lot of data when streaming, isps want Netflix to pay them a fee for providing the same the speed that they offer to other sites who don't use as much data. And yes, some of these providers also have their own streaming source in mind, and if Netflix is too slow, people will switch. Also, If Netflix has to pay a fee to keep their speed the same they will have to raise their subscription fee, and people will switch anyway.Internet service is a very high margin product. If they throttle a less informed consumer's netflix, the consumer will see it as "my internet is too slow to play netflix properly therefore I need to upgrade to a faster service." This allows the company to make “almost comical profit.”', "1. Who are you going to convince to cancel service for a month? 2. The ISPs don't actually care about the bandwidth use or quality of service they provide. Their only purpose for throttling netflix is to blackmail for more money.
How were we able to get to the Moon within 9 years of going to space, but in the 42 years since we can't send someone to Mars?
No focus. Little to no public support. No funding. Next time you're talking with people ask them if they believe space exploration is important. They will likely say, fuck no. .
Why did so much technological innovation happen in the old world rather than the new world? Was there anything stoping the Native Americans from inventing new things?
The best book I've ever seen on this is Guns, Germs and Steel by Jared Diamond. In short: Europe and Asia had the fortune of many domesticable species of animals and plants unavailable in the new world and much of Africa and Australia. This led to all sorts of advantages, including disease resistance as a result of animal agriculture which spelled doom for native peoples in the western hemisphere. But it all goes back to which plants and animals were found where a people lived, basically. In effect, luck of the geographical draw.
Why does it take Amazon several days to "prepare" items for shipment?
It doesn't take days for Prime members, or people who pay for faster shipping. If you take the cheap/free shipping, you're standing in line behind all the people who paid to get it quicker.
Why is my 2004 Desktop Faster then my 2013 laptop?
Faster in what of many senses? From the specs you posted the laptop would be faster when running at full power and once everything is loaded into RAM . But if you're doing anything over a network, that could contribute, the desktop machine is almost certainly running a faster hard drive . Your laptop though, it's worried about power and heat, both of which could be problems. The first is that it's probably by default running some conservative power setting that will limit performance most of the time to save battery life and produce less heat. Heat could be an issue, if your laptop is unhappy about overheating it will ramp down performance. Also, it depends what you're doing, the Pentium 4 might be a bit faster in a purely single threaded application, whereas the AMD should be quite a bit faster in a multithreaded.
Why its bad to eat too much microwaved food.
It's bad to eat processed food in general. The microwave has nothing to do with it. I'm assuming you are thinking about radiation or something along those lines. All a microwave does is shake the molecules to heat the item.
Why are the psychological symptoms of autistics so heavily reinforced through accomodation when many other psychological disorders are dealt with by trying to normalise the sufferer, such as vehimently contradicting schizophrenic delusions?
I wouldn't say that treatment for people living with schizophrenia involves 'vehimently contradicting the schizophrenic delusions.' CBT for psychosis is gaining traction and I do believe in the model, but it's not contradicting per se. It's more about facilitating the development of critical thinking skills and helping people incorporate all of the available information before they draw conclusions. That being said, I don't know the answer to your question.
Why does the military use phrases such as Oscar Mike, or other lingo like Tangos?
Because when you need to know the exact letters in a word, or string of characters, individual letter pronunciations are extremely easy to confusing. M and N for example are extremely hard to tell apart and when you are trying to be extremely precise and efficient it's not helpful to have to repeat yourself multiple times because the person on the other end can't tell if you're saying M or N.
Please explain "negative entropy" (negentropy)
While this isn't negative entropy, it's a different way of looking at the universe that may help. What we think of as entropy isn't necessarily going from order to chaos, but from less complex to more complex, from holding less information to holding more information. Minutes after the big bang the universe is largely a cloud of hydrogen gas. Small imperfections in the distribution of this gas coalesce into clouds, galaxies, solar systems, and planets. If this development from simple to complex is a part of how the universe works, then life is inevitable, because you reach a limit of complexity without self perpetuating patterns.
When applying for a job, why do companies make you manually write in all your work experience instead of just looking at your resume?
As a hiring manager, I've got to say the biggest reason I see is that people lie, a lot. You'd be surprised the amount of resumes that don't match applications.
How does Alzheimer's kill?
Simplifying a lot: Alzheimer's has two ways that it works. The first way: if you assume that your neuron pathways are layed out like a sheet of paper, Alzheimer's crumples that paper into a ball, which prevents the neurons from working right. The second way: there's a buildup of some stuff in your brain that forms plaques . These two things combined basically shrink your brain while at the same time preventing it from working properly.
How do interpreters hear the next line while interpreting what was just said?
There was just a post about this on /r/languagelearning! The answer is practice, practice, practice. Simultaneous interpreters train rigorously over a number of years. They start by listening to something and repeating it word for word. Then they close the gap between repetitions until that they're speaking and listening at the same time. Then they start translating and listening at the same time. Not rocket science, but certainly not easy.
Why have humans evolved so quickly compared to other species?
If there is not pressure to change then it won't happen. Also potential genetic variation. But why do you say humans have changed more?
Why does China seem to be relatively under control compared to most of the world?
> They're not dictatorships. They are though. It's incredibly totalitarian over there. Most social media is blocked so communication is limited, and people vanish if they criticize the government. The whole 'China is under control' thing is literally that. They are under control in a very effective way. China gets things done that it wants to get done in a hurry with no riots or anything because God help you if you riot or don't get it done.
How can the same flaps create lift for takeoff and destroy lift for landing?
The flaps dont destroy lift. They increase the surface area of the wing which provides more lift for the same speed.It allows the aircraft to fly at slower speeds which wouldn't be possible without the flaps.
what Wolfram Alpha is suppose to do?
Generally anything involving hard data, maths, or statistics. For example: If you use it to look up a country, you get population figures, numbers of vehicles, area, GDP, km of roads. That sort of stuff. If you use a normal search engine, you get pages that have information about the country, but it is likely to be less numbery. So information about the history, tourist spots, the current government, etc. Not that you will not get the same information as WA provides, but WA is better if that is what you are looking for. It is also very good at anything related to maths, being tied into Mathematica. And looking for amusing Easter eggs. Go ask if it is Skynet for example. Edit: Some examples of the latter. * [Are you Skynet?]* [Are you alive?]* [What is the airspeed of an unladen swallow?]* [What is six times seven?]* [What is your name?]* [What is your favourite colour?]* [What is your Quest?]* [Why?]* [What is the loneliest number you'll ever do?]* [What is the moon made out of?] Most of the answers are obvious.You can find out about the [aircraft overhead].
If the universe is full of stars giving off tremendous amounts of heat, why is space so cold? Wouldn't it warm up eventually?
The actual 'space' part of space, doesn't have a temperature. Temperature is the measure of energy in stuff, and space is 'the lack of stuff.' Beyond that, space is very very empty, there's a lot more emptiness than there is 'stars'. Where there are stars, the 'stuff' in space is most definitely warmed up. For instance, the surface of the Moon, which is effectively 'in contact with space' heats up to over 200 degrees in the sunshine.
Can pack animals, domesticated or wild, perceive a human to be the "alpha male" or is it only limited to their species?
Not all pack animals can perceive humans as alphas. We have domesticated wolves, so clearly they show some leniency when it comes to this, otherwise it probably wouldn't have been possible. Since we have studied wolves intensively, we know that this is possible. But there are a lot of animals who could not or would not make that association. For example, hyenas probably wouldn't associate a human with alpha no matter how dominant or powerful the human was. From what I've read, these animals would perpetually try to overthrown a dominant human, which is why lots of rural areas get hyena attacks. I think that, apart from wolves, we haven't truly studied other species natural interactions with humans, and probably for good reason. You don't want to throw a human into a pack of African Wild Dogs to test this theory.I have 7 dogs huskys and a border collie. People often ask who is the alpha. I tell them I am. Amongst the pack different dogs are more dominant at different situations. However it is generally our smallest female who is the most dominant. Our largest male is always bottom of the pecking order. Dominance is usually settled amongst the dogs without aggression, it is often settled with a stare or body language. Each dog has a role in the pack and we have a couple of females who neutralize any aggression before it gets out of hand. Often this is by physically placing themselves between two dogs who are squaring up. Sometimes they will actually create a distraction by barking in the garden or at the front door.
When I tell a website to "save username and password" where is it stored? Is it safe to do so?
The most common way is as a cookie stored on your browser which contains information such as your username and password and which site this cookie is associated with. When you open up Reddit for the first time and expect it to remember your login Reddit will send a request to your browser and ask if there is a cookie stored there which belongs to Reddit, if there is Reddit will use this information to log you in automatically. If you clear your browsers' cookies this note disappears and Reddit no longer remembers your login. Now regarding whether or not it is safe It is completely possible that Reddit stores in a Database they own a unique ID associated with your username. Along with this could be everything you've done on this website. Notably everything you've ever written. Possibly everywhere you've visited along with other activity. Since your credentials are stored on Reddit's Database it is possible that something could happen and for whatever reason they are compromised and Reddit loses this information to somebody. That person could then know your Reddit persona, not necessarily who you are in real life, but everything you've done on Reddit. Edit: Also, security-wise with cookies. There are ways for malicious software to look at your cookies and obtain the information stored there. They can use this to login as you and get any information that way. Note though it is difficult to do any of this, there is plenty of security in place to prevent these things. And I no idea if Reddit stores all your information or not, I'm too tired to find out right now, maybe later.
Why don't smartphones have FM-AM radio/ over-the-air television tuners?
Just joining the torrent, but money. I have the same model of Note 2 that's for AT & T in the states, but the Big 3 here all have internet radio services so it's disabled. I wonder if it's actually in there. It'd be cool if just changing roms would fix it but it's probably not in there at all. My old HTC Desire C had an FM tuner. Irritates me that my iPod doesn't. Thankfully 6GB data is a lot of radio app", 'AM radio is massively prone to electronic interference, including that which one would get from the radio transmitters that the phone is using to connect to the phone and data networkMy HTC One has an app built in that lets me hear FM radio. But you have to use headphones though.It's just not popular enough to justify the cost, in the US at least. It's common in Asia though.
Why aren't physicists concerned about catastrophic explosions created by particle accelerators? Whenever I read about a more powerful accelerator smashing particles at higher energies than ever before, I get nervous.
I feel like the other comments are kinda missing the point- sure, when measured against large-scale things the energies are tiny, but it is certainly conceivable that having that large of an energy *density* would be able to cause something catastrophic, since all of that energy is concentrated into a tiny amount of space. However, we are almost completely certain that we will not cause any kind of catastrophe because nature has for millennia been providing us with collisions between two particles of energies that we can only dream of, in fact the highest recorded energy of any particle is the [oh-my-god particle], which was a particle that was measured to have the kinetic energy of a baseball traveling at 60 mph, which turns out to be approximately 10 million times more energetic than the energies achievable at the LHC. If those kinds of energies aren't destroying the universe, nothing we do is going to matter either.
Why do even numbers feel safer and more pleasing than odd numbers?
On the T.V. volume. I go crazy when it's on an odd number. To this day, I still don't know why. But only T.V. volume.
Since the moon and mars are both uninhabitable without great technological burden, why would we send people to live on Mars when the moon is SO MUCH closer?
We've been to the moon already. And the current missions that people are talking about doing are more just to work out how to get people there and back again safely, much like the Apollo Missions did for getting people to the Moon. & nbsp; When we do get around to the point where we're sending people up to live and work long term, both the Moon and Mars will likely have research stations set up on them, with the Moon getting them first, simply because it's closer and easier to reach. & nbsp; But even long term living and working, such as goes on currently at the International Space Station, and would go on at any future Moon & Mars research stations, is still a far cry away from colonization. And when it comes to sending people to live there on a permanent basis, Mars has one important feature that the Moon lacks: an atmosphere. While the Martian atmosphere is too thin and oxygen deficient to support human life, it would be possible to go outside for brief periods with only a pressure helmet, and not needing a full suit.
What would be the evolutionary advantage for dinosaurs to develop wings without being able to fly?
Longer jumps, briefly get carried by a wind. Larger body, more threatening to predators. Ability to jump out of tree's clifs and survive the fall, etc
How does the Euro work?
Each country issues its own coins and notes, but they're interchangeable. That means that you can spend an Irish Euro in Spain with no problems. I don't know whether there are mechanisms for repatriating currency to its country of origin, or whether it's just allowed to get all stirred up. Last time I bought Euros they were all French, but spending them I got all sorts in the change.
Why does your body feel physically ill after experiencing emotional trauma?
Because it is. We like to pretend like the mind and the body are separate things, but they're not separate at all. When you experience emotional distress, your body reacts physically to that distress. It releases hormones and endorphins that trigger things like your fight or flight response. And afterwards, it needs time to get back to normal. Also, once you calm down, your body assumes that whatever life-threatening issue has happened is over and it wants you to calm down as well and take stock of your situation and recover. Ultimately, your body really doesn't know the difference between your girlfriend dumping you and a tiger chasing you through the jungle.
Why does every human look and act different from each other, while almost every other species of animals look and act the same?
Other species *do* act and look differently, you just aren't trained to see the subtle differences. You *are* trained to see differences in other humans from the time you're born.
how does magneto fly?
If he creates a strong enough magnetic field, he can just repel off the Earth's metal interior. What's more amazing is how he can control magnetic fields to manipulate a single object. Try attracting a single paperclip out of a bunch with a magnet.
How did we figure out that fingerprints are 100% unique?
It's not 100%. It's like if I toss some marbles on the floor. Chances are overwhelming that they will land in a unique arrangement each time. You could in theory get an identical result, but it's extremely unlikely.
