Why is spicy food so prevalent in Asian cuisine but not so in western cuisine?
Come to the southwestern United States where we eat lots of mexican and Latin American food. Many of us like it hot. I'm white as fuck but spicy food and hot salsa on some tacos is comfort food for me", 'Is there something I am missing with spicy food? Every time I eat spicy food my mouth is burning and I can’t even taste the food. Is there a secret I don’t know?Ever been south of the USA border? Mexico conditioned me to be able to survive Thai foodHot and spicy foods are somewhat common in traditional recipes from Hungary and South Italy.
Does Nebula actually look like that or is it just the camera?
What I want to know, let's say I'm in a space ship, and I don't care about distances or the objects still being there Would these huge nubula ever look like we make the pictures look? Traveling at superluminal, subluminal? Is there any way those images can be seen with the naked eye out of a window?", 'I know that a lot of pictures have been artificially colored in after because the pictures taken were in black and white, but I don’t know how true to life they would be', "Kind of. Almost every space picture you see is color and contrast enhanced to make it stand out better. If you took a picture with a long exposure camera and a good telescope [this is what you're more likely to see]. Its not nearly as colorful or impressive as the heavily edited Hubble images. Hubble is incapable of taking color photos, it only has a super sensitive black and white camera onboard. To get the color images they put one of 38 filters in front of the camera which gives them much more scientific information to work with than just red, green, and blue pixels would but means they need to merge those together to get a standard color image; but since they have so much more information might as well enhance it and make it look cool! And that's why pictures from probes and telescopes are sooo much more colorful than you will ever see with your own eyes.
How can living organisms be alive if they are composed of non living atoms?
Well sir, that's THE big question of biology. What's life?", 'The same way a computer does what it does but individual silicon atoms in it cannot. Life is just a very complicated chemical and mechanical processit’s like looking at a single brick from a brick house and asking if it can provide shelterYou can build a moving car with lego. But individual lego pieces can't move on their own. Organisms become alive because millions of "dead" atoms were combined in a special way that lets them interact and become alive as a whole.
How do removable storage devices like usb retains the data stored in them even when it is not connected to a computer? I read that flip-flops require constant current to retain data stored in them.
Flash memory makes use of Field Effect Transitors FET's. Field effect transistors make use of the fact that applying an external electric field can have a massive effect on the the electrical conductivity of certain transistor designs. In flash memory, a certain type of insulator that can store a static charge, is fabricated directly above a FET. Then a metal contact is placed on top of the insulator. In order to set the value of the memory, a voltage is applied to the contact, which creates a static elctric charge in the insulator. This tiny static charge is enough to cause the FET underneath to conduct electricity, producing a value of 1 in that particular memory cell. A large array of these types of transitstors can be used to store data as a series of ones and zeros. In order to rewrite the value of a cell, the opposite voltage is applied to the top contact. This neutralizes the charge in the insulator, causing the FET to stop conducting, resulting in a value of zero.
If you brush your teeth at night and don't eat anything until morning, what are you really cleaning when you brush in the morning before eating breakfast?
Bacteria grow in your mouth. When you eat food, they rapidly produce acids that are damaging to your teeth. By brushing before you eat, you lower the number of bacteria, and so also reduce the amount of acids produced. Ideally, you'd always brush *before* you eat, although people often do not at night. Brushing is about getting rid of the biofilm, plaque, not food.
How did old video games fit into such small spaces on cartridges?
I recently found a cool video on YouTube that explained some tricks that they could use. Will post again if I can find it. But basically, in Super Mario for example, notice how the bushes and the clouds have the same form and differ only in color. So that's one sprite saved. Then, look at goombas. They're symmetrical. So you only need to store half of their sprite and then you can mirror the pixel to get a full Goomba. Similar techniques can be applied for all sorts of objects and characters. Even for whole levels. Imagine the super Mario levels are actually divided into blocks, you could make the level symmetrical and bam, you only need to store half the level. You can continue to divide further and reuse e.g. only a quarter of the level etc. People used a ton of tricks to save storage and reuse resources.
Why can’t sound engineers create a consistent volume level throughout an entire movie or TV show, it’s either too quiet or way too fucking loud at different times?
Imo a better question would be why isn't there a separate track for SFX and dialogue so you could adjust both independently like many video games let you do.Seriously. Theme music is way too loud. It may be mixed perfectly to a million dollar sound system but if it cant be played on 2 speakers, its still a bad mix.
What's the difference between 32 and 64bit computer systems, and why aren't there, say 128bit systems.
It's the amount of bits per clock that can get calculated.Your pc has for example a processor of 1Ghz. This means that your clockrate is 1000000000Hz a second.Then you got 32 or 64 bit. This means that with every clock, your pc can calculate 32 or 64 bits simultaneously per clock cycle. It isn't bad, but you see nothing of difference in calculation time using a 32 bit program on a 64 bit computer. Your program still sends out 32 bits because that's the way it was programmed. Using a 64 bit program on a 32 bit computer doesn't work because the computer can't handle 64 bit calculations. Why there is no 128 bit? Because you need more transportlines on your motherboard, you need more connections, you need faster and better chips, it's very expensive and not interesting for regular pc use.The same question was asked a few years ago on r/askscience. Hopefully this answers most, if not all, of your questions: _URL_0_
Humans suffer from muscle atrophy when they don't use muscles for extended periods of time. How come bears can hibernate for months and be just fine?
This is matter of much research and no full answer is known, but..it is true that despite both weight loss and non-use, bears maintain muscle mass to a much higher degree then a would-be-hibernating human. In humans lower neural activation is a precursor to muscle mass retention. One study suggests bears lack the mechanism that alters muscle mass in the absence of neural stimulation. Other studies suggest that bears can generate amino acids from uric acid . Yet others suggest that shivering can serve. Whats also true is that they utilize fat stores so from an energy perspective it's not that hard to explain how they _could_ retain muscle mass by focusing energy utilization on fat rather then what would happen if you or I fasted without the other slowdowns associated with hibernation.
why aren’t 2x4’s actually 2 inches by 4 inches?
Nowadays timber is milled and planed to ensure it looks a little more finished, thus it's a little smaller than 2' by 4'.
Nyquist Theorem perfect signal reproduction
> Is there some type of assumed curvature There is usually a low pass filter on the analog circuits to avoid aliasing. The filter's performance is very important.
Why is carbon dioxide the only gas that is used to make drinks fizzy?
It's cheap, easy to obtain, and is already present in the body, so it poses no threat if it gets dissolved into the bloodstream somehow.Carbon Dioxide is used because it has a very high solubility in water , and it is relatively non-toxic either in its gaseous or dissolved form. The only other commonly available gases with extremely high solubility in water are Ammonia , Chlorine , Hydrogen Sulfide , and Sulfur Dioxide . I think that in beer, nitrogen is only used as a sort of aeration/foaming agent, not as an actual dissolved gas since its solubility in water is virtually nonexistent . The other benefit of Nitrogen in beer systems is that it displaces oxygen which oxidizes the beer and makes it taste off after a short time.I'm pretty sure it's not the only gas that can do this, but what I do know is that it's completely harmless to people, inert, tasteless , and cheap and easy to produce. And I'll venture a guess that no other gas meets all of those criteria.
WHY do batteries work?
Alkaline batteries are filled with a chemical paste that reacts with a metal when placed in a conducting circuit, otherwise the paste sits happily, its essentially electroplating via chemistry while we draw from the reaction. Rechargable batteries are simply batteries with an extra layer of forethought to use chemistry that allows that electroplating reaction to run in reverse, and I've seen videos about lithium ion rechargeables having some kind of porous carbon i think that is done to prevent the opposing electrodes from building a metal whisker between them ruining the battery in the repeated charge/recharge cycles.
Why is nutritional science so inconsistent and convoluted?
The biggest problem is that not everyone's body handles the same foods the same way. Different studies might take place in different areas with different proportions of people with different reactions. For instance, lets say you have your study on butter take place in a region that has a high proportion of people who have difficulty handling lactose owing to a low use of milk and milk products in local foods, this could render a different result than the same study being conducted in a region where dairy and cheeses are a common element of many meals. Aside from population differences, some people also have issues related to health problems that are not genetic as well. The other major problem is that you have to consider the source of the studies, as some studies at some points in the past might have been designed to be favorable to one point of view or another due to being sponsored by food producers who will want to be able to use the results to promote their products.Science is often based on controlling as many variables as possible, this is nearly impossible to do with humans as genetics and lifestyle play a large role. Another big problem is the effect of money’s influence on studies. For a long time, companies that relied heavily on the sale of sugary food would pay scientists to study the affects of fat being negative and this led to the whole “fat in foods is evil” craze. There’s a very interesting episode of “Adam ruins everything” that goes into the history of this. Many scientists can find exactly what their looking for instead of what is correct.
Why do Americans show the price of a product without tax?
Companies that advertise nationally want it that way, and in some ways, consumer do too. Let's say McDonalds starts a national campaign advertising, say, $2 Big Macs this month. There are a lot of customers that would be upset if they saw that ad, then walked into a McDonalds and saw $2.14, or whatever on the menu. Because it's worked this way for so long, American accept and understand that $2 really means $2 + tax.Marketing. If it looks cheaper people are more inclined to buy because they feel like they are getting a deal. Plus we are just so accustomed to the government taking our money indirectly that’s we just accept everything is a lie
What is actually involved in the process of "hacking" into something, and how is it different to that poorly portrayed in movies?
Hacking is just the process of getting access to parts of a computer system that you're not supposed to have access to. This is done by exploiting security vulnerabilities. Even the best written software will have bugs in it and some of these bugs will have the effect of giving someone access to things they aren't supposed to have. The biggest bug is the user. If they can be tricked into giving someone else access then there's no need for fancy software.
Why do voters in the USA have to register as a voter for a political party before they are allowed to vote?
We don't need to register with a party to vote in the general election. Some states - not all - require voters to register with a party for voting in the *primary*, which decides which candidates run for each party in the general election. That's intended, I believe, to keep people from voting in the primary for the party they don't support in an attempt to sabotage that party's goals.
Given the sugar-free options, why haven’t they made candy with aspartame, splenda or stevia?
There's a alot of sugarfree options in every grocery store here in sweden atleast, like 4-5 brands with several flavors for each brand in sugarfree icecream aswell. There's alooot of options and some of them are really good.
Why are eggs such an important cooking ingredient in a lot of recipes, including baking?
They are not used that much in Asian cooking. Alternative thickeners and binders are wheat flour, maize/corn flour, potato starch, tapioca starch, arrowroot, guar gum, xanthan gum, carrageenan. Bacon and eggs were [invented by Sigmund Freud's nephew]. Factory farms and marketing play a part.
Why does the red light at a stop light disappear when viewed through a blue tinted window (like the thing at the top of a windshield that reduces glare)
We perceive color when light hits an object and reflects off it. Depending on the material, some wavelenghts of light will be reflected, and some will be absorbed. The tinting material is absorbing the red wavelength, so it won't be reflected to your eyes while the other colors still are reflected.
Why have movie trailers not only become much longer but now most seem to include the entire plot and end scenes condensed into the trailer?
Because millions of dollars spent on thousands of focus groups show the movie marketing folks that these types of trailers increase movie ticket sales, foreign distribution, etc. If there was any possibility they would make less money as a result of longer, more comprehensive trailers, they wouldn't exist.Well, thinking of the plots of older movies would it even have been possible to condense those to a trailer ? Maybe they had to do different trailers, because the plots were just to complex or large, to be condensed like that.This isn't new! People have been complaining about trailers being long and giving away the plot since the beginning of time!
The sun obviously has much stronger gravity than Earth, so why does the Moon orbit Earth and not the sun instead?
The moon orbits both the sun and the earth. The sun does pull harder on the moon, and the moon's path never curves away from the sun. In a sense it shares the earth's orbit around the sun. At the same time it orbits the earth due to the earth's gravity.
Why is the winter solstice only the beginning of winter and not the middle?
Winter is November, December and January in Ireland. That's what's thought in school as we still use the Gaelic Calender. _URL_0_", 'Think about it this way, at some point there is a situation where the number of hours of day warms your area the same amount as the number of hours of night cools. For the sake of this example, let say that is 12hr day and 12hr night. the moment you get more night than day, you area starts to cool: until you get to the solstice like you mentioned. But remember the solstice represents the max cooling of your area. Past this day, the you area is STILL cooling until we reach 12hr day/ 12hr night, only after than, will the earth start to warm again.
How does EMDR (Eye Movement Desensitization and Reprocessing) work?
I have been a therapist and trainer for a technology called IEMT since 2008 and have had a lot of success using it. [Here's a case study I wrote for a Psoriasis client] with pictures. The key thing is that we can only pay attention to one thing at a time. Multitasking is a myth for the science). So when we're thinking of 'that' problem AND then we forcefully look and pay attention at an external stimuli then the amplification of said problem diminishes. What gives IEMT better results is that it has procedures to build in new resources into the problem state. We also deal with the 5 main patterns of chronicity which makes [IEMT more effective] than all of the older eye movement techniques.
Why do front wheel cars handle better on ice and snow than rear wheel?
They only accelerate better because the weight of the engine on the drive wheels. They don't stop or turn any better than rwd.When turning and accelerating one component of the acceleration is sideways which helps pull the car through the turn. Also there's usually more weight over the front wheels so they dig in a bit better. When the wheels do cut loose, front wheel drive is much less prone to fishtailing and spinning. If the driver hits the gas too hard so the drive wheels cut loose, a front wheel drive will "understeer" or stop turning while a rear wheel drive will "oversteer" or fishtail.
Why are feminists called feminists and not equalists?
Because most of the modern feminists doesn't even want equality, they want more power than men have.
Where do magnets get the energy to do magnet things.
I'm not seeing this question being asked so I'll ask it. Consider two magnets arranged so that they repulse each other. One is floating above the other. Is any energy being used here? Wouldn't energy be required to hold up the floating magnet?
Why are humans in general (including me) opposed to or frightened of bugs/insects? Why do they make people uncomfortable, despite their size?
It's difficult to say. In short, there are a mix of factors involved. There may be a cultural component. The reason I am NOT afraid of any insects is because I've been exposed to them many, many times, enough to overcome any cultural stigma imposed on me. However, I was exposed at a very young age. We also may be just afraid because they can bite and sting us, even though other animals can harm us. Maybe lack of understanding in the ecological benefits of insects is playing a role, justifying the fear for them by not being able to correlate their importance to anything, but these are just hypotheses.
Why do graphics in older movies look so shoddy years later, when there was a point the graphics seemed realistic?
Stuff look like shit back then, there was just no other option. So we created everything on a curve. I think that was one of the reasons why science fiction wasn't more popular to the mainstream, because some mainstream people couldn't get over the poor special effects.Because "realistic" means close to real. So whatever is the best graphically at the time is considered realistic. As graphics improve only the best are considered to be realistic and the others are no longer considered to be realistic. The graphics remain unchanged, the world remains unchanged it it only our perception of and understanding that changes.> at that point in time we are comparing it to real life and we think it looks good believable, real. No, we aren't. That's the flaw in your argument/question. It's underpinned by something stated as fact that isn't true. We have suspension of disbelief. So, though it doesn't look believable/real, it serves as a representation of the real. Nobody watching Jason and the Argonauts thought the skeletons looked real, but it was the best representation we had at the time.
How are herbivorous animals, for example cows, able to grow so big eating only grass?
There's just this specific job in the animal world that they do well. It's being really big and hanging out in groups to reduce the risk of getting eaten, all while spending that hangout time eating and eating and eating. Predators spend most of their time not eating and laying around. I love how the roles can be so different and successful in their own way.
why, at airport security screenings, do electronics need to be put in a separate tray? Can't scanners see through a bag/luggage?
Lots of incorrect answers here. Laptops have a certain CT scan profile and when you put other objects on top of a laptop, that profile becomes mixed and you can't determine if it's the laptop that has organic material or the object on top.
Why should I let my car run in cold weather?
There are little rods in your engine that slide back in forth lubricated by oil. If the oil is cold, the rods will touch bare metal and can get damaged. If the oil is warm/hot, the rods are properly lubricated and there won't be grinding/scraping in your engine.
Is there a good, logical, or historical reason why some password setup fields severely limit the field length or disallow particular characters?
It's a mixture of several factors. For many ages, programs stored the password, for comparison when you tried to log in. Then they didn't want you to type too many letters or things that their input routines filtered out. That might include fancy characters, escape characters, non-printing characters, non-Roman characters, . Then they figured out that storing passwords was bad, so they stored encrypted passwords. That still has the same storage limit. By today, everybody knows the best practice is to store a salted hash. That doesn't matter as far as length or character set goes, but the instructions, password hints, and **user password behaviors** are often not changed. This maintains backwards compatibility with the user's legacy password behavior. Some GUI tools may impose constraints, and that's user visible for programmers who want to write less code by using these GUI tools. It's not lazy programmers, it's usually budget cutting bosses that picks this.Historically, yes. A long time ago, computers were limited to the "size" of the user ID and password fields , because of memory limitations. And they also couldn't include "special characters" because the operating system interpreted these characters as commands, or separators for commands. As an example, [for /f "eol=; tokens=2,3* delims=, " in do @echo %I %J %K] - DOS and Windows had to "interpret" what exactly the user wanted with that, and so / = * . @ % could not be included in non-commands.
If friction causes heat, why does moving air create a cooling sensation against skin?
Moving air isn't moving nearly fast enough to create the amount of friction that would be noticeable to you as heat. At the same time, moving air will cause the moisture on/in your skin to evaporate. Evaporation requires heat and that heat comes from your skin. So if the air temperature isn't too far off from your body temperature you can end up feeling cold.The air that comes into contact with your skin absorbs heat from you. Moving air does this but is also constantly replaced by cooler air, which then absorbs more heat, and so on and so on. So you feel cold cause your skin is losing heat to the air.
Why are children allowed to star in TV and movies but are not allowed to work “normal” jobs?
There are limits to working hours. My sister's twins will be in Britannia S2. And the could only be on set for 3 hours. Once that limit was reached, they were rushed off set as it was illegal for them to be there after. Many days she travelled to parts of UK to film and if there were delays, after 3 hours she would have to leave even if no filming was done. Still got paid though
How it would be cheaper for socialized Medicare in america vs paying for health insurance.
There's one other partial consideration beyond what people have mentioned - productivity outside medicine. Socialised healthcare leads to greater availability of healthcare, and thus greater use of healthcare. A person who goes to the doctor, gets a course of antibiotics and quickly recovers from an infection is far more useful than a person with no treatment who takes 5 weeks to be fully recovered. People will be able to work more, and work more efficiently, which raises the tax base and hence revenue. Obviously, you'll see more people through the system - it's all up to the economists to work out which effect is larger. It probably won't offset the full cost, but it provides a partial offset.
What is different about a good student instrument and a pro level instrument?
Just like with any precision instrument , you get better performance out of better materials and more careful craftsmanship. Cheap instruments are usually made of plastic and are created on an assembly line. They won't sound as good, they won't last as long, and they may have defects. Expensive instruments made by hand by experienced professionals out of high quality ingredients will look better, sound better, and last longer. I bought a mid-range wooden clarinet and had it tuned up by a professional instrument repair man and I can tell you it sounded much better than my old plastic practice clarinet. And the levers and joints on the keys worked better, so they were quieter and the instrument was easier to play.
How do planes just go missing in todays high tech world?
Perhaps it's not as high tech as you'd like to believe. Plus it could be the gubberment! /tinfoil
How do Olympic athletes make money?
Probably coaching and private lessons. Tangentially, pretty much every quarterback from my high school when I played took us to the playoffs and played D-1 ball, and now they each own/run or work at one of those youth quarterback/football training centers that have popped up in the last 15 years. On some level I think the answer is, after sponsorships while they're training and competing end, possibly nothing at all.In Germany Most athletes that are not in Professional team sports are employed by the government . They‘re exempt from duty with pay except for staying current with their certifications and their initial training. Also Sponsors.
How come granules in teeth whitening toothpaste damages your teeth enamel but not oral prophylaxis that uses metal things to clean your teeth?
My dentist always recommends that I only brush for 20 to 30 seconds twice a day and focus on regularly flossing for better gum health. The frequency and duration of which most people brush slowly grinds away the enamel over years, whereas you're not getting poked by your dentist 2 to 3 times a day all year.
Why does Earth hardly ever get hit by meteors?
The Earth get hit ALL the time. According to NASA, there is an asteroid the size of an automobile hitting the earth each year, while an asteroid the size of a football field hit the earth each 2000 years. _URL_0_ Basketball-sized object hit the earth daily and volkswagen-sized objects hit every couple of week. According to Donald Yeomans, an Nasa astronomer. _URL_1_ The difference is the atmosphere of the earth that burn out most of that stuff before it can reach the ground. So you really need a bigger rock to cause significant damage on the ground and since most of the surface of the earth is either water or empty field, the chance of one hitting a populated area is relative rare, so we don't hear about it in the news.
Why are Congressional officials paid during shutdowns, but not blue collar government workers?
Because there Congressional officials would be the ones to decide if their pay was cut during the shutdown. They don't want to dock their own pay.
Home Owners Associations. What? Why? Why all the horror stories?
I don't know if there's data on how people are generally satisfied with HOAs or not but I think its reasonable to say that most HOAs are pretty benign and disputes are handled by the book. Mine for example is really just about making sure people's parking spots are kept available and keep the grass cut and streets plowed when it snows. I appreciate that. But you can get horror stories when people abuse power and while I can quit any club I don't like the leadership that does get more complicated if your house is involved. And sometimes going to the press and creating an embarrassing story is a good way to get things resolved.
If a star in its red giant phase absorbed a star similar to our sun would it refuel the red giant and make it go back into its main sequence stage?
No. 1 star + 1 star doesn't equal the sum of those stars, it equals one hell of a collision, which will blow matter all over the place. It's more likely that the red giant will lose out on the event.No, it will put it further away from that stage. If you wanted to "fix" that kind of star, you would want to remove mass, not add it.
Why can’t humans see all wavelengths, and what causes them to be harmful?
Think of evolution as the laziest person you know. The ability to see and process a wavelength of light costs energy in processing. Therefore, evolution will try to find the least energy solution to being able to navigate the world, so it just picks a part that gives information valuable to humans. NOTE: Evolution is not directed or intelligent and does not have goals, but in this case, you can think of it that way. Really what happens is humans that don't waste energy processing UV rays have a greater chance of surviving long cold winters.Limiting the wave lengths we can see allows the brain to focus on things that are important to our survival. Hawks and Spiders see UV because it helps them hunt. Some amphibians and fish see infrared because it helps them. We don’t hunt by tracking trails of mouse pee, or need to seek out warm spots like a cold blooded creature, so those wavelengths would add noise to our visual cortex.
What is the difference in Propaganda and Fake News
gray", and "black" propaganda. White propaganda is entirely truthful, although usually selectively truthful. Black propaganda is simply false and deceitful. Gray propaganda mixes truthful and deceitful elements. "Fake News" is usually gray propaganda or black propaganda . & #x200B;
Why is the temperature usually less cold when it's snowing?
Like somebody else said, cold air is most often dry. I used to live in Yellowknife, way up north in the northwest territories. Around October to mid November, it snowed a bunch. Once it hit December, it almost never snowed. It was regularly a sunny, gorgeous looking day, and when you walk outside it's minus 45 with windchill. It was a frigid, dry, arctic cold, with no possibility of precipitation.
how does dyslexia work? are you dyslexic in all languages?
Dyslexia isn't just mixing up letter. Dyslexia is caused by a different way of thinking. People with dyslexia think in a much more visual way than the average person. They also have a higher ability to be able to mental view objects from different perspectives, rotating them in their minds. But because of this ease sometimes they do it when they don't mean to. So letter and words rotate or rearrange themselves in the person's mind making it difficult to read. This is much more common, or triggered by words that lack a clear visual meaning. The, a, an, that, this, those, and a lot of other words similar to those don't have an image that easily represents them. People with dyslexia get tripped up by those words causing them to disassociate. So the answer to your second question is yes. If you are dyslexic and your first language is English, were you to learn another language you would have the same difficulties in that language because of your dyslexia.
how come older video games have fewer glitches
Older video games didn't have the ability to be patched post launch, so what they shipped was what people got. Kind of why a lot of glitches have become infamous. If a game now has a glitch, the developers will just fix it.
Why do computers, phones, laptops etc. get slower as they get older?
Most people are saying that there hardware does not get any slower, but technically there is some damage to some of the internal components over time just from operating. That can cause performance problems, but the effect will be very small compared to software issues and you won't likely notice it until something fails.
Why are Americans allowed to pay bail to get out of jail?
You're innocent until proven guilty. Jail is to hold people considered a risk, such as for flight. But bail provides an incentive to return if they let you go: to get your money back. Note that jail is not the same thing as being in prison as part of a conviction.
Why is there tax on second-hand items at thrift stores? The gov’t has already collected tax on the item the first time
States charge sales tax any time a product is sold. It doesn't matter if it has been sold in the past, it gets charged every time. It would be a big logistical headache to have to prove that you have already paid sales tax previously for every item. It's much simpler to say that all sales are taxed, regardless of if that item has been sold and taxed in the past.And someone would figure out how to have everything be second-hand and sell it that way. A very simplified example would a primary producer selling to a subsidiary at cost, with that subsidiary then claiming the goods were "second-hand" and thus avoid sales tax. .
How did early explorers map out the shape of countries so accurately? One specific example would be Matthew Flinders with Australia.
By careful measurement. Let's consider the alternative. It's called getting lost. Certainly people did get lost, but nobody preserved the maps they made, because those maps get you lost. The maps that survived from 1803 to today are just the really best ones.
Why are migranes so much more frequently by women than men?
Women's hormone fluctuate more than men, which contribute highly to having migraines frequently. But that gould just be a cause. Migraines can occur due to several factors in the body such as diet and musculoskeletal disorders
Why is there such a huge repeated number of same instruments in orchestras?
Two reasons. 1) Because nothing is amplified. You have a violin playing against a trombone, you're going to need more violins in order for them to be heard. Some orchestra venues have a house pipe organ which is used as part of some performances. There's only ever one of those because they're **loud**. 2) You need more than one violin to play certain chords. Then in order for the chords to be heard you need to double triple or more up on the violins that make up those chords. Soon ends up as a lot of players.As already said, you need multiple players per part so each part is heard depending on the natural volume of the instrument, but if you’ve ever gone to an orchestra, a stage filled with many people is much more sweeping and fulfilling than a smaller ensemble.
Why do our bodies not ache after sleeping for several hours vs. when awake in a stilled position for several hours?
OP must not be over ~30 yet because that's about the age I started waking up sore most days.
What are the pros to nuclear energy? Is the storage of waste still a problem? What roadblocks are stopping it from being viable?
Nuclear power is already viable. The roadblocks are mostly due to peoples fear and perception of Nuclear power as a ticking time bomb when it really isn't. We have methods of safely storing nuclear waste and have been able to do so for decades. Research into Thorium reactors is ongoing. They are potentially much safer than modern reactors and use a more commonly available fuel source. The catch being that the waste products can't be used to make Nuclear weapons so the US + Soviet governments didn't fund the technology. Modern reactors are much safer than those produced in the past. Fukushima for instance was built in the 70's, and many have argued that if it's anti-tsunami wall was a tad higher the disaster wouldn't have occurred. A similar reactor just up the coast survived for that exact reason.
If employees can legally end an employment contract at anytime by giving 1 months notice, what is the purpose of 2 year and 5 year contracts?
This question can't be adequately answered without knowing the country, state , and city you're talking about. Contract law and labor law varies widely, and and answer for one area isn't the same as another.
How can data be protected from hdd failure without having to write every single bit in 2 separate places?
Basically parity computation. Drobo can use one or two parity drives. Let's use an example with one party drive. Say you have 4 drives. Each block of each drive is mapped to every other drive. So if you use even parity. Then whatever value block 0 has on drive 1,2,3 you calculate the parity so everything is even. Ie if drive 1,2,3 all hold 1s then drive 4 also has to hold a 1. So when one drive fails you can infer what data was in the lost drive.
Why’s it so hard to breathe when there’s strong winds blowing in your face?
I'm so confused. Theres all these divers saying it's a reflex and all these sciencey folks explaining it by pressure differences. Both claim to be right and both are believable. It's true though that I can breathe in the wind but I have to center myself first. I guess I'm believing the divers?", 'This is just the mammalian dive reflex. It usually occurs when your face experiences flowing water but this also happens with air flowAnd to add onto that, how do people who jump from plane for parachute manage to breathe during the fall ?', "Jump in really cold water and you'll feel the same effect. Its your body responding certain sensations, not what you're consciously thinking. Its like when you touch a hot stove and reflexively pull away before you even feel the heat. What is really interesting is that in babies, a rush of air to the face causes them to inhale. Its one of a human baby's most primal instincts. Their Palmer grasp is amazing simply because of their relative grip strength.
Why is the audio mix on movies/TV so much quieter than YouTube/online video?
It's hard to answer your question completely without knowing what kind of YouTube videos you are watching. HBO is professionally produced and they tend to go for a cinematic experience with a lot of difference between the quiet parts and the loud parts. YouTube content can be created by anyone so some folks will create cinematic content like HBO does and lots of others will create normal content where the audio stays at a nominal level. Also many folks don't understand or use professional techniques so the audio can be all over the place in terms of level, quality, etc.
Why is carbonated/seltzer water made with carbon dioxide and not oxygen?
Oxygen causes things to spoil. CO2 does not.Oxygen gas is flammable. CO2 is notFor the same pressure not much oxygen can be dissolved than CO2. I don't think anyone has offered oxygenated water commercially. I have heard of nitrogen being used for beer. As for watering plants I don't think it would hurt, but I don't think it would help much since CO2 is processed through the leaves and not the roots. More reading:_URL_0_
If the entire global electrical grid was fried (by a coronal mass ejection or something similar) would the internet be salvageable?
It's up to each website to have backups of the data, so, yes, possibly the internet would be back up as soon as power is restored. Though a CME may fry electronics too , so perhaps some of the websites may be down until they restore.In your scenario, internet recovery is well down the priority stack. In fact, loss of the "entire global electrical grid" may put civilization at risk hunting and gathering don't require internet.
Why are airlines specific about the weight of bags when the passengers weight vary so much?
Passengers weight fluctuation is accounted for because they can't unpack 20 pounds of fat. They have a hard limit on bags to a) get more money and b) you can always throw away some clothes", 'In addition to what others have said. People have to pick up the bags to load/unload the plane. Personnel injuries are more likely with heavier bags.The bags are picked up and loaded by airline workers. When those workers are injured, by lifting a bag that weighs too much, it's very expensive for the company. It's a much better idea to protect workers from injury from a bag that weighs too much. Heavy passengers have the muscles to move their weight around, and they know that they weigh plenty. It's not a weight we expect workers to handle. The weight of the passengers, and their baggage, is ~1/6 of the weight of the plane.
Why are Animals scared of us Humans?
Funnily enough humans are actually pretty big for how dangerous we are. It's something like 70-80kg for an average adult male- that's as much as a freaking Jaguar, more than an adult wolf and even as much as female gorillas. An animal might guess a human is much more physically powerful than we actually are purely on size. Not to mention our biped stance which means we stand over almost all creatures in the animal kingdom. Of course, we can't back that up that is, until we make spears, javelins, bows at which point we basically go straight to apex predator.Because we eat them ..If u tried to make friends with something trying to eat you, you would not pass on ur genes or at least have a significantly lesser likelihood of producing as many offspring as a parent animal that did not get eaten .. the animal that doesn’t get eaten teaches it’s offspring not to get eaten which in turn teach their offspring not to get eaten .. it’s kinda literally evolution lol .. as time goes on there are significantly more animals that are fearful of humans since the once’s that weren’t for eaten lolHumans evolved as predators. Animals recognize this and they react to us like they do all predators. Prey species flee in fear, and other predators avoid conflict unless they see us as the prey animal.
How can the gravity from the sun keep the planets locked in orbit, but we are weightless in space.
Good question. A force as you'll learn in high school is a vector. Simply put, it means it can affect a body in 2 ways. It can either increase the velocity of a falling object, making it fall faster and faster, or it can change the direction of the velocity, making you move in a constant speed but continuously changing direction. Since you were always in contact with the earth, the sun is only trying to change the direction you are moving in. And relative to earth, on a satellite You are using all of the gravity only to change your direction and not your speed. So currently there aren't any forces that'll make you feel like pulling or pushing.
How do people get snuck up on by trains when they're so loud?
There are a few things. Electric trains can run surprisingly silently, even at fairly decent speed, but most of this kinda thing happens at slower speeds, I think. If trains are just cruising at 20 or 30mph, they really are very quiet. They're running steel wheels on smooth steel rails, there's almost no wheel noise to contend with. The exhuasts go upwards, or sideways so head on, they're a lot quieter than you think, and getting hit by a train at that speed isn't even in the same ballpark as being hit by a car. Cars are built to deform if they hit an obstacle, trains are built . well not to, frankly. You get hit by a train and it'd be like being hit by a lump hammer, never mind being knocked onto the tracks then pizza-wheeled into a few pieces.
Why do most people find rats unappealing but other rodents such as squirrel and hamsters cute?
Just to second everyone else pretty much, a big part of it is association with the plague, alongside just being thought of as pests/dirty in general. There aren't that many pets that have a commonly seen wild counterpart , so people are more likely to see a wild rat than than a wild cat or dog or heck, even a pet rat. Also yeah people hate their tails for some reason - they're fuzzy! They're cute! Idgi! - but yeah rats are awesome and cute and I can say that bc I have had hamsters, guinea pigs and rats and rats are the most fun for sure.
How does the earth spinning on its axis not slow down or lose momentum?
Objects in motion tend to stay in motion unless acted on by an outside force. The outside forces are very small compared to the mass of the Earth, so it's slowing at a astronomically slow pace.Because there is no friction in space, so there is nothing to slow the earth down. Now the earth does actually slow down a little, because of the moon, its just extremely slowI read an article that said in 180 million years there will be 25 hours in a day because of how gradually the earths rotation is slowing.

Is it worth the effort to wash your hands after peeing, if there's bacteria on the public bathroom tap?
Any advice from actual doctors or people with actual solid evidence? I'm pretty sure that's what this post is asking for and not just your opinions
How does an extension cord overheat?
It's all about the resistance and shielding, extension wire is thin to bend easy and due to the lack of heat shielding will over heat and melt the rubber or plastic on the outside.
Why do anti-biotic medications require a prescription?
Because you could take too few of them. When you stop taking antibiotics because the symptoms are gone, the bacteria that remain, the antibiotic resistant ones, multiple and spread into the environment. When the environment is full of antibiotic resistant bacteria, everybody dies. The rest of us don't trust you. We don't trust you to only take them when you have a bacterial infection. We don't trust you to take enough of them to kill every last harmful bacteria. Also, killing off the beneficial bacteria in your body, which outnumber the human cells by the way, isn't a good idea and it should only be done for serious diseases.
How do game companies make a game engine that requires more power than contemporary computers can make?
A lot of it comes down to math. Mathematical formula's are used by software to draw more and more realistic pictures. The more realistic you try to get the longer it takes for the computer to process the math. Something like a video game has significantly more than just graphics going on, which takes up processing time, when you add in more and more realistic graphics you're adding larger and more complex functions for the computer to process. At the time Crysis was released, high-end computers could run the game at the highest setting, however it took so long for the computers to process everything that it was often running at a slideshow pace so it wasn't playable. It's one of those things where at some point you just need more processing power to run everything the game engine wants to do, to be able to run the game quickly enough to make it comfortable to play. For example, hyper-realistic CGI today can take a single high-end desktop computer hours or even days to render a single image. They often use render farms to render stuff like this, each one either rendering a single image , or a part of an image, to then be stitched together later. Now try drawing these images fast enough to get 60 of them per second ..you have to either sacrifice quality or get an insane amount of computing power working together.
How do you win a lifetime of *blank*
This will depend on the contest. There is no standard, though I'd say pizza? Over time. Toilet paper? They might just have a one time bulk option.
Why, although I speak good English and am able to understand regular conversations, movies and album skits etc. do I struggle so much to understand lyrics in English songs?
I am no expert but I'd say human brain first focus on the tune or melody the song has to give. I usually give 4-5 hears before I could actually focus on the lyrics.. Only exception would be foo fighters, where I deliberately chose to focus on lyrics first.
Why is it that we can’t superduper charge our batteries with a super «shock» like one of those heart rescue thingies and it’ll be full?
First off, the defibrillator you mention charges capacitors. They don't store as much energy as batteries, and they deliver very little energy to a body. Now a few reasons. The cells charge by ions transferring from one terminal to the other. They take time to do so. Even if they were fast, the energy needed to charge a 1AH 3 V cell is more than 3 watt hours. For that to be delivered in 1 hour requires a 3 Watt power supply. To supply that much energy in 1 second requires over 11 kW. It would also need huge wires and connectors. The inefficency of the charging process would destroy the cell instantly.
Can someone explain why there’s actually no way to basically revive something or someone dead?
First we have to make the distinction between brain death and clinical death, because they're not the same. Clinical death is cardiac and respiratory arrest. This is, depending on what caused it, sometimes reversible. If you restore someone's heartbeat and breathing within a few minutes, you can resuscitate them. For example, you mentioned drug overdoses in your question. If someone stops breathing and their heart stops because of an overdose they're clinically dead. If you restart their heart and breathing within a few minutes, you've resuscitated them after they were clinically dead for however many minutes. Brain death is the permanent cessation of brain activity. This one is irreversible. It's game over. Clinical death leads to brain death because if you're heart isn't beating and your lungs aren't breathing, no oxygen is getting to your brain, and the cells quickly start to die.At the moment there are scientists working with different plant matter hoping to find a "bandage for the brain" in order to keep brain cells alive. Which is sort of neat I think.
If photons are massless, then why do they have momentum and produce a force? And if light has energy wouldn't that mean it has mass?
In classical mechanics the momentum is p=mv, but this doesn't work for particles, instead, quantum mechanics take place with momentum defined by p=h/λ where λ is the wavelength. So, by the equation E² = ² + ² a photon have energy E=pc=hc/λ=hf where the frequency f=c/λ. E=hf is the energy of a photon postulated by Einstein. & #x200B; & #x200B;
Why We Can't Remove The Cancer Cells With Surgery?
That's what happens with skin cancers. However, cancer is a generic name for a lot of specific diseases and not all of them are so easily treatable.
If music CDs are burned with the opening tracks towards the center, how are open-world video game discs burned?
Think about a cabinet of folders. You might have 100 folders, in order, with a label of 1,2,3,etc, 100. You could store your life information chronologically, starting with your birth certificate in the first folder, death certificate in the last folder, and everything else organized in between. However, just because you stored all of your documents chronologically doesn't mean that the folder cabinet can't be used to store other documents which aren't related to time at all. For example, if you wanted to put a piece of paper recording your street address in folder 1, and your driver's license in folder 2, nothing is stopping you. You still have your information organized . In a similar way, when reading the disk, you don't need to know what order the information is stored in, only *where * it is stored. Specific actions and objects are stored at different locations and are read when they are required by going to the specific location, not determining where it is in a sequence.
Why could retro cartridge-based games not save player data without a battery backup? Why do modern cartridge-based systems not let you do this as well?
It's a cheap and elegantly simple solution to the problem. Nintendo had originally planned on using floppy discs. Which at the time were an ideal storage medium. They held more than a cartridge, and had a little bit of extra non-volatile storage for saves. Though for one reason or another the Famicom Disc System was never ported over to the NES. Chip based re-writable NV memory was expensive at the time. Mostly EPROMs, as NAND Flash wasn't really a thing in the 80s. This is basically how those Everdrive cartridges work for storing games. But EPROMs weren't cheap, and only good for a limited number of writes. A few kb of RAM and a battery though, dirt cheap, and can be written to an unlimited number of times. It's a very robust system that ended up lasting far longer than it was ever intended to. Some of those games still have working saves almost 30 years later. Fun fact, the reason gen 2 Pokémon games failed so quickly is because the battery also powers a real-time clock for in game events. That drains it faster. As for modern carts based systems, they certainly could. The DS did. Again its probably cost savings. They only use as much flash as the game needs. Some games have surprisingly big save files.
How exactly are imaginary numbers useful?
i is useful because sin and cos can be represented by e^ also known as Euler's equation. This makes calculus much more convenient. Also imaginary is a bit of misnomer. It's not that the number doesn't exist it just exists on another dimension of the number line. Normally you have just one axis say an x axis that goes from negative infinity to positive infinity. Now add a y axis to this graph. On this y axis are all the imaginary numbers
Considering all the talk of colonising Marss, wouldn't it be easier to just make a moon base?
The moon is closer so it has that going for it, but Mars is a proper planet with real planet like gravity and an actual atmosphere and even a day night cycle that humans might be able to adapt to . So if you want to build a home in Earth-like conditions Mars is much closer than the Moon. The moon will be a necessary waystation to other worlds, but it doesn't really have much going for it in terms of colonization: A small gravity well, a bunch of moon-rocks and maybe water, plus a view of earth or a sky without earth depending on where you settle down. The moon is a nice place to visit, but you wouldn't want to live there.
How can boats have holes in the bottom to drop things into the ocean?
Because the surface with the hole is above the water line. The simplest model would be a pontoon. Two large tanks provide the buoyancy, and a flat deck is placed on top of them. But the deck is above the water. You could cut a hole in it and it wouldn't affect the buoyancy.
How do we know what different parts of the brain do?
By damaging them and seeing what happens, usually. Medical experimentation has a long history, much of it gruesome or unethical, and yet much of it necessary for medical progression and to ultimately save lives. In the case of brain regions, we've determined what they do by a combination of observing behavioral changes after accidental injury, and deliberate destruction of parts of the brain in living animals to see what happens.
how were the trigonometry tables for sine, cosine, and tangent discovered without a calculator?
You can work anything out by hand, if you are willing to put in the time and effort. Here's a good article about women who used to spend months working out artillery firing computations in the days before computers: _URL_1_", 'You can figure out some from Pythagorean theorem and identity functions. cos^2 A + cos^2 = 1^2. and sin = + etc. Ptolemy had calculated tables out nearly 2000 years ago. You can also calculate from a power series. cos A = 1 - + - .
How did electron knows which path is shorter? (e.g How electricity will choose to flows through metal rather than wood)
Think of it as water running down a rocky mountain slope. The more resistance, the less the slope and the more rocks in the way. The water will go down the steepest slope. It doesn't matter if it's height difference or voltage difference, it's the steepest way down which counts.
Where did the cracking noise go when someone receives a text message?
Old phones used to go in to a low power mode where they would just listen on a frequency and wait for the tower to broadcast a wake up message. When they got it they would try and connect with the tower. Initially it would use the highest power signal to do so, but once the connection was established the power would drop back down to the lowest level necessary. These days phones are always connected as they are constantly sending and receiving data, so you don't get those wake up power bursts any more.
How do bees survive if we keep taking honey from them?
In past times, the bees usually did NOT survive, since there were no removable frames in the beehives . Nowadays, the bees build honeycombs on frames that can be removed one by one. Thus a beekeeper can leave them enough honey to survive the winter. It's also common to harvest all the honey and provide a substitute for the bees so they can survive.
the science/reasoning behind contra-rotating propeller blades. Either boat or airplane; preferably airplane.
I think the torque explanation is a bit incomplete because you can cancel the torque with a pair of separate propellers as well, what's the difference then? The difference is indeed in the airflow because in the case of separate propellers each one will generate a vortex, the torque cancels out but the end result is you have two streams of rotating air so some energy has been spent making the air rotate in this useless manner. With a contrarotating propeller not only the torque is cancelled but also the rotation of the air, the end result is a straight stream that provides more forward momentum for the same ammount of energy.From an efficiency perspective, a single prop will produce some rotation in the air or water behind it. Some energy is lost in that rotation. Counter-rotating props reduce the rotation, and thus reduce the energy loss. The energy loss is not spectacularly large; the complexity of the drive mechanisms often outbalance the savings.
How do dryer sheets remove wrinkles and/or reduce static if it's just the small sheet? Wouldn't it not be touching all the clothes in the load?
I'd like to know if they still work when you take the clothes out when they're still damp? Or do the clothes have to be somewhat dry?
Why does the nurse look in the toilet bowl after you’ve taken a drug test?
You're supposed to catch the urine mid stream. So if theres no urine they can assume that you used fake urine. That's why it's best to put some in the test and some in the bowl.
does the North Pole move?
The North pole, or true North, does not move. This is the center point defined by the Earths rotation. On a plastic globe, this would be the spot that holds the globe on the stand and it spins around this point. If the Earths rotation changed or started to wobble, this would change true North and the North Pole would move. A catastrophic meteor impact, mega volcano eruption, or millions of years, could cause small changes to this location, but it's safe to say for the sake of argument that it does not move. Magnetic North is not directly under the North Pole though and it does move. It's also not constant everywhere on Earth. It's caused by the magnetic dynamo of iron in the interior of the Earth, much like running electricity through windings of wire create a magnetic field. Because it's caused by the different layers of the Earths core moving against each other, it moves over time, sometimes even reversing completely with compass needles pointing South. It's also not constant everywhere on Earth, with some locations having a different adjustment to determine true North from Magnetic North. Compasses allow this declination to be adjusted to the location it's being used in. [In this photo] The outer ring of numbers can be spun around to different offsets for finding true North. That compass has 20 degrees of magnetic declination, so it's probably being used on the Northwest Coast of the USA. In other words a properly adjusted compass in California may be accurate, but if it was used in New York the magnetic declination would be different and you couldn't use the same offset. [This Map] shows the offset for North America. It's even farther for other continents and places around the world. Magnetic North also drifts faster than hundreds of thousands of years. It's actually moved far enough since we started using compasses, for us to have to make adjustments to our compasses and offsets.
What's the difference between CS (Computer Science), CIS (Computer Information Science, and IT (Information Technology?
**Computer Science** - Math behind creating computer programs and systems. **Computer Information SYSTEMS** - This is what businesses called Information Technology in the '70s and '80s. It is a set of things working together to control information on computers. Databases, file servers, etc. **Information Technology** - Basically the same as computer information systems. The technology we use to process information from fax machines to smartphones.
Why do identical twins look slightly different? Shouldn't they be 100% identical?
Identical twins split off from the fertilized egg very early in the development process . There are many opportunities for variations to occur during development, because the timing of genes being activated and deactivated can still change how things turn out. In females , there's a process that randomly inactivates one of the X-chromosomes in every cell, which might also slightly change the genetic makeup of twins. And then, even before they're born, the environment they're exposed to will also affect them. There have been studies that show slight differences impacting neural development, which changes what they like, and consequently what they do. This will further shape them differently.
Why NaCl is not lethal?
Say you have a giant rock at the top of a hill. If you push it off, it will fly down the hill and crush everything in its path. Now say you have a giant rock at the bottom of the hill. If you push it as hard as you can, it won't move or crush anything. Pure sodium is like the rock at the top of the hill. It will give off a ton of energy if you add water to it. It will also give off a ton of energy if you add chlorine to it. But after it gave off its energy, it doesn't have any more energy left to give. Sodium chloride is like the rock at the bottom of the hill. You can set fire to a wooden log. But you can't set fire to ash.
Why does film footage from the 60's often look much better than footage from the 80's given that technology should have advanced?
[Technicolor] was a very high-quality way of recording color images onto film, but it was complex and expensive. In the mid 60's it began to be replaced by cheaper processes. A lot of those processes resulted in films that have degraded a lot over time, but the technicolor films have stood up much better. [Here's a video] that touches on some of this.Films made in the 60s were made using equipment that was high-quality, but also very expensive. In the late 70s and early 80s, the technology did advance, but it advanced in the direction of making it *cheaper* rather than *better*. Another thing is that many movies from the 60s, as well as important archival films, have probably been through some sort of digital restoration, cleaning, and archival process in the meantime, meaning they have had modern technology applied to them to make them look better. Newer films from the 80s likely have not been through an extensive restoration process yetWhat exactly are you comparing? Feature films? Documentaries? News footage? Others in this thread are contrasting 35mm film with home VHS, but I don’t think that’s what you meant since you specifically asked about film. And this new documentary is based on previously unseen 70mm footage, so it’s going to look a lot different from other material shot at the time.
How is Netflix able to operate whilst being in so much debt?
Debt isn't necessarily a bad thing. When most people purchase a house, they go into debt. They get assets that they hope are worth it, and Netflix does the same. When you buy a house, you don't go bankrupt because you don't have $100,000, you make an agreement on how you'll pay them back with interest and Netflix does the same. For Netflix's debt, they've had quicker access to more servers, more programming, better programming, marketing, and other things to help them make money. As long as they can pay off their debt as planned, no one is worried about it. The banks are happy, and Netflix is happy.Netflix’s current ratio, their ability to pay short-term debt, is at about the middle range of global companies in their industry. So, as long as they keep the bills paid they should be okay. I don’t wanna get too technical for this sub lol hope that helps?', "Netflix could be in serious trouble actually, so they might not be in great shape. Other people have pointed out student loans are pretty much the same thing. The idea is that you go into debt to in order to go to school and increase your future earnings. You take on that debt to invest in capital other capital might be machines that are make some good. Businesses at the beginning of their lives can accumulate debt to increase their long term earnings just like how a person takes out student loans. Eventually, Netflix needs to make more money in order to service the debt and make profit, just like I have to make my student loan payment each month. The problem facing Netflix currently is that multiple other firms are entering their market , so they might not make enough money to pay their debts and return profit. Which is similar to how it is possible to take out student loans and then drop out of college or invest in a career that doesn't make enough money to offset those loan payments.
How do cells know what to do when every cell contains the same DNA?
There are markers when the body develops as cells are turned on. That's why heart muscle cells only develop in the heart, nerve cells go where they need to go. & #x200B; Fun fact, the markers in mammals are vitamin A based. I was studying with a professor who worked with rats that were exposed to mega-doses of vitamin A when the momma rats were pregnant. & #x200B; There were some fugly rat pups and then there were those who had neurological issues -all due to when the rat moms were exposed to the mega-doses of vitamin A. & #x200B; Working with other researchers, they had pinpointed when certain mammalian brain structures developed. & #x200B; & #x200B;", 'Think of your DNA as a cookbook. If you want to bake a cake, you go to the cake recipe and follow those instructions. If you want to make soup, you go to the soup recipe. So while each cell has the entire cookbook, they only ever use a few recipes. I’m not exactly sure HOW they know they need a specific recipe. I believe it has to do with cells differentiating during development, as well as where the cells are originating from .
How do smart phones not over heat?
Something I haven't seen as a response yet is also also important to keep in mind, and that's energy. Mobile processors are specificly designed to be as energy efficient as possible, with less importance given to performance. The applications available for phones are purpose built for these devices. Much more attention is given to optimization, making games and such much easier to run. When a desktop CPU is using 125w compared to a phones 2.5w, you can expect it heat up faster relative to it's size.Oh they do. Was doing something fairly intensive. Had my phone in the cup holder on a summer day. Sun was very bright and the car’s AC died. Got to where I was going, phone was almost too hot to hold. And on the screen there was a message: “I’m not working until I cool off”
