All placental mammals have a "belly button", but it's really only obvious in humans. Why is it so? | I would imagine the major factor is the lack of fur. You simply can't see most mammals' belly buttons. Edit: grammar |
How does a chirp frequency in a radar work, and how does it improve resolution? | Chriping in radar technology works by sending a radar chirp and then working some black engineering magic on the receiver for create a *single sharp pulse* from the chirp . This improves *[range resolution]* because the pulses after your magic filtering on the receiving end are much sharper than in a normal radar. Anot... |
Why do cities enforce federal immigration law but not other federal laws like tax review? | It's not their job to enforce federal immigration law, it is their "duty" to assist federal law enforcement and assist with federal detainers. For example, let's say NYPD picks up someone who is wanted in NJ for murder. It's their responsibility to alert NJ and detain them until NJ makes a decision if they want to come... |
why gaining/losing weight is all about a calorie surplus/deficit, but still people keep saying things like "Don't eat carbs after 5 p.m.", etc. | Yes, at its very basis, losing weight is a matter of calories in needing to be lower than calories out. But that doesn't mean there aren't certain foods that make it hard to stick to that. There are certain foods that do make you feel satisfied / full for longer. Eating things rich in protein will stave off the hunger ... |
If I was an employer, would I be allowed to fire whoever I wanted for no reason? | That's highly dependent on your location. The US is *generally* "at will" employment - meaning you can quit or be fired at any time for any reason, as long as that reason doesn't amount to discrimination based on protected attributes . Some jobs - particularly city workers - are unionized / tenured, and their contracts... |
Why does freezing certain foods lower the quality of it? | Pretty much everything we eat was, at one point, alive. Living things are made of cells. Cells are like little water balloons. When water freezes, it both expands and turns into crystals. The expansion of water can stretch out and burst the cells. The crystals can puncture the skin of cells. Both of these things end up... |
Why do PCs/laptops need fans but not a phone? | A few reasons. * The intensity of work done on a PC/laptop is usually higher. This roughly equates to heat. Video games at full resolution and frame rate will equal a lot more heat than facebook on a phone. * Phones are made to wick the heat away. They don't have much free air inside so the heat goes straight to the ca... |
Why are members of the UN Security Council still allowed to vote or veto when they are involved? | The key point about the veto power on the Security Council is that without at least tacit consent of those five powers, whatever the Council chooses to do won't have any teeth. So yes, when one of the five members does something stupid, there's nothing the UN can do. If the members were forbidden to vote, they would li... |
Why do some people instinctively laugh/smile in bad situations, like a funeral? | I am not sure there is a good answer to this beyond some people laugh as a defensive mechanism even when the social situation isn't appropreate. See also: girls giggling when you ask them out in 4th grade . DAMN YOU BECKY . YOU DESTROYED LOVE .. DAMN YOU TO HELL! |
What is scar tissue and why does it develop? | The simplest example I can give for how scar tissue works is for muscles. We don't have the ability to grow new muscle tissue. When your muscles get bigger, the tissue is getting larger and the connections inside are getting reinforced but the amount of cells inside hasn't really changed. So when you get a deep cut, ho... |
Why are the lungs virtually one of the only organs you can stop completely from use(other than death?) | With training, people can and do slow down their heart rate as well. As for why we've evolved the ability to temporarily control our breathing, that's just speculation, since it may have occurred before humans existed. Try r/askscience |
during the winter, why do i have to turn on my car and wait for it to get warm before i could drive it? | You don't have to wait for it to get warm unless it is extremely cold, like -20. Other than that, let it run 30-60 seconds so the crankcase oil can distribute evenly. In the old days of carberators, warming up was needed to get the gas to vaporize correctly and the air/fuel mix to be right, but in modern fuel injected,... |
Why some kidnappings gain so much media attention, whilst thousands of others don't. | Generally, the kidnappings that gain media attention are those by strangers, which, as you can expect, grab people's attention . The vast majority of kidnappings are by people known to the victim - eg. a non-custodial parent takes off with their kid. That kind of scenario doesn't carry a whole lot of implications for t... |
if I saw a cop and suddenly ran away from him for no reason, does he have the legal right to arrest me? | he could deem your actions suspicious and stop you for questioning. but probably not outright arrest youFrom wikiPolice may stop a person if they have a reasonable suspicion that the person has committed or is about to commit a crime, and may frisk the suspect for weapons if they have reasonable suspicion that the susp... |
Why black widow anti-venom can only be taken once in a person's life | Antivenin is made by injecting small quantities of venom into an animal. The animal's body reacts to the venom, producing antibodies, cells that attack the venom. We then harvest those antibodies. When someone gets bitten, we inject the antibodies into the person and they attack the venom. The problem is that, from our... |
Why is DJ Khalid famous? | He makes all the beats and sounds for his music, then hires people to sing over them. He's a producer. He's famous probably because he has connections and was able to get other famous people to sing over his music.To use his language: Because he sells his shit. |
Why are 911 calls, when played back, always in such low quality? | When you have something like the 911 call system, something that lives depend on, and something that you know works as it is right now, you DO NOT fuck with it. That means if the recording component makes it a little grainy, you live with it.Phones in general have shitty quality. You can use the best recording system i... |
Why is managing a country so hard? | There are 330 million people in America and each one has a different opinion about how the government should function and what it should and shouldn't do. Nearly all of those people are more or less logical, so which one is correct? The one who wants to avoid *any* negative consequences with a very cautious, plodding g... |
[EL5] Oil Prices versus Gas Prices | Add transportation. Add taxes. Add enough profit to pay rent on a gas station. Add wages. Add theft. Subtract a bit if it attracts people to a sufficiently profitable convenience store. Net result: you'll pay more in higher tax states, in states farther from refineries, in areas with high rent, and in areas with high c... |
I love cats but I'm allergic to them. Is there any way I could own a cat without suffering? | Beyond just getting a naked cat you may also want to consider getting a cat breed that is so called "Hypoallergenic" which means that they don't trigger an allergic reaction, however the legitimacy of that is uncertain. The company "allerca" has supposedly genetically engineered two different cat breeds to also be hypo... |
How does Playboy expect to keep going when going non-nude? Aren't they just going to be another Maxim type magazine then? Aren't there plenty of those in the market already? | There are plenty of magazines with nudes, too, and Playboy was pretty tame compared to many of the others. Playboy has always been known for high quality fiction and articles -- a lot of cutting edge scifi and essays have been published there over the years. They expect their circulation to improve with the move to non... |
Why did Russia not discover America before Columbus through Alaska? | Russia didn't control Alaska until the 17th century. Back in the time of Columbus, Russia didn't really exist as a single nation. It was a bunch of countries in what is now Western Russia and Ukraine. |
What will happen to Japan in 100+ years if the population continues to decline? | The effects of an aged population are already being felt in Japan and Germany, to name another. This is a phenomenon observed as more countries become more economically developed. When a country grows its economy, many people don't need to have children to make money, and can afford better healthcare. In addition to th... |
Why was the telephone company a monopoly that had to be broken up into smaller companies, but Ticketmaster isn't? | It is, and should be. But selling concert tickets isn't as important a function in the national economy as the entire telecommunications infrastructure was. Breaking up Ma Bell had a bunch of very good effects in spawning new businesses and more rapid deployment of new technologies, and some of those were somewhat pred... |
if all computer programs are created from a computer program, how was the first computer program created? | Switches to set individual binary values. The programs were input that way, and later memory was invented so that they could be stored. Even later automatic methods of inputting values were invented like paper tapes with holes punched in them. Using programs to construct other programs is a much later invention. |
How are packets of light/data separated? | The question needs clarification. With a "packet" of data, do you mean a \'bit\', and how the bits are separated? In this case, it's a matter of the light being \'on\' or \'off\', and then it's separated in time. You can have several \'bitstreams\' over the same fiber by using different colors of light, and just sendin... |
How do they film planes flying in the air for movies? | With other planes or helicopters, or with fast panning cameras on the ground. It's not really very difficult to film a flying plane at all. |
In baseball are there different batting strokes, as there are in cricket? | Only thing I can think of would be opposite and bunt. I guess you could consider line drives, fly balls, and pop ups different hits if you wanted to. Mostly it is hitting the ball into the spot that will most likely get you on base or more importantly score a runner already on base. Swinging for the fence is rarely the... |
Why is there no way to store solar energy from panels on roofs? | there is. many houses have a battery or power storage if they have solar panels. a lot of other houses sell the extra electricity that they dont use back to the grid.Capacity. We simply aren't able to build enough batteries to store all this energy. There aren't enough natural resources and factories to create this. No... |
Why most people are much more scared of really big insects than mammals like mice and squirrels | Can relate less to them. Squirrels have roughly human-like features, legs, arms, nose, mouth, eyes, bones etc. They're like a smaller, furrier version of us. Insects however are very different, so we can't really sympathise with them, so in general are a lot more nervous towards them.Evolutionary speaking, insects and ... |
Why does Root Beer foam so much when poured onto ice cream? | It's a combination of two major factors: - Ice cream has a lot of surface area, which means more nucleation points. More nucleation points mean more bubbles. - Milk and cream have a higher surface tension than water. This means the bubbles are stronger. ----- The reason why Mentos in soda makes it fizz is because all t... |
How are older films / tv shows that weren't filmed with a HD camera remastered into HD? | Because they were recorded on film, and film doesn't have a "resolution" like digital video is, so they can scan the film into whatever digital resolution they wish. Before the days of digital cameras, you could take your film negatives into a photo developing place and have them do prints at about any size without any... |
How does salt help de-ice roads? | The freezing/melting point of salt water is lower than it is for water. So, adding ice to an icy road will cause it to melt at a lower temperatureSalt lowers the freezing point of water, meaning instead of 32°, it may be lowered to say 20°, so if the temperature for that area is > 20°, the snow will start to melt as it... |
Why doesn't the bag need to inflate in order for oxygen to be flowing? | When you blow through a straw does the straw inflate? Of course not. You can think of the bag as a really big and loose straw. Oxygen comes in one side and your mouth is on the other side. If you are breathing the gas in or it leaks out then it doesn't build up and fill the bag. If you close off the end and force lots ... |
what purpose do the towers disguised as palm threes serve? | They are cell phone towers, made to look like trees so that they don't look as ugly. I guess they tend to be installed in areas where people would complain about a normal looking cell tower being ugly. Personally I think they still look ugly and fake, but they do look better than a cell tower. Edit: I've also seen ones... |
Anonymous shutting down child pornography sites. | How do they shut them down? Normally when you take control of a server you have complete control over what a server does, from delete everything on it, to change a web page. Now it depends the degree of security. How do they find them?Child porn sites aren't outwardly advertised as such. And they are hard to pin down. ... |
is there ever going to be a time where our cameras will plateau in quality? How great can cameras get? | Physically, we will start to see diminishing returns . Software will become the biggest thing that effects quality. Software will probably eventually be able to mitigate blue from shaken shots, change depth of field , become better at removing noise and false colors, more accurately determine color balance and skin ton... |
Why does a double pendulum motion create such a sporadic, random pattern? | It's "chaotic": very small differences in the initial conditions make very significant differences in the final motion. There are equations that govern how it work, and there are patterns to how it moves. It's just hard to replicate the motion, because of the difficulty in swinging a pendulum *exactly* the same twice. ... |
if you leave an appliance, lamp, charger, etc, plugged into the wall when not in use, does this eat electricity and run up your electric bill? | Depends on the device, for a cell phone charger, yes. The older ones use to use quite a bit of power when no phone was connected. Newer ones turn off 99% of their stuff when there is no phone, but they still consume something. As for the other things, well it depends, but stuff like a cheap toaster, no, it contains a p... |
As of today the minimum wage in Australia is $16.87 an hour. If the USA has a much bigger economy, why is their worker pay so much worse? | cost of living is substantially higher than the US I believe.What came first? Is the economy so much bigger because we pay our workers less? Cheap labor enables cheap goods and services that are exported worldwide. Increase labor costs mean higher prices not just for the US but worldwide. In other words, cheap labor co... |
does older automatic cars use much more fuel? | Overdrive transmissions actually improve gas mileage. Older cars often do use more fuel just because they don't have all the engine efficiency improvements that exist now. |
What is Bayes' Theorem? | Bayes' theorem is one of the central ideas of conditional probability, which allows you to produce the probability of events given related, previous events. It states: The probability of event A happening given event B has happened is given by the probability of both A and B happening divided the probability of only B ... |
How do sites like gfycat pay for their bandwith? | 1. Build a simple, useful service 2. Build a massive user base 3. Sell to someone who will monetize and scare away all the users |
Why it's forbidden to plug a UPS to a surge Protector? or Daisy chain surge suppressors (assuming you are not overloading them). | UPS's and surge protectors both use Metal Oxide Varistors as components in the circuit. The way these things work is by converting excess voltage to heat. They are designed that they have a "clamping voltage" which is the maximum amount of voltage they allow through, before they start absorbing the excess voltage in th... |
How do people become physically addicted to something if they get a daily break from consumption while sleeping? | If it's a physical addiction, and you sleep for 8 hours, your highest craving begins in the morning. All day you'll be wanting that drug, until you get it, because its been 8+ hours since you last had it. If it's a mental addiction, sleep doesn't matter. You want the drug every waking moment. Sleeping prevents consciou... |
Why is one's first reaction to hitting their finger is to put it in their mouth? | For the same reason animals lick their wounds - there are some natural anti-bacterial properties to saliva that we know, instinctively, will help if there is an injury. [source] Its 'instinct', so it just happens - our brains are wired to know that, if there is an injury, to try to lick it in order to get saliva on the... |
what are eugenics and why is reddit so for/against them? | Eugenics is the practice of controlling the gene pool by allowing some people to have children and preventing others. **Pros**: The human race as a whole will "improve" . **Cons**: Taking away people's freedom to procreate. |
Why is Laserdisc and analogue format and DVD a digital one. | Laserdiscs were on the market in 1980, well before we had figured out how to make digital recordings on a disc. So we used the technology we had on hand: analog. That long answer by mucus, quoting wikipedia, is correct but goes into details not asked by the original poster, and therefore not answering "like I'm five." |
Why can't they make putting nicotine in cigarettes illegal? | They don't "put nicotine in," like it was caffeine in a soda or something - it's part of the tobacco leaves themselves. |
what happened that resulted in Canada going into a recession. | The main reason for the recession is the current crash in oil prices. For Canada to get out of the recession oil prices need to hit $70 a barrel, that is the sweet spot for companies to start spending money on drilling again. |
Why is it so easy for experienced hackers to hack into a large organization's system, yet I've never heard anything about hacking a car's odometer? | Hacking an odometer is not exciting. Hacking the CIA is', "There's no point. If you have a 100K mile car, and you hack the odometer to read 1K, it will become immediately apparent to anyone who opens the hood that the odometer has been messed with. If you drop that 100K to 50K, you aren't getting that much of a better ... |
What would happen if, all of the Mcdonald's Monopoly food prize recipients went and claimed their prize at one specific location? | No. They are reimbursed by the McDonald's corporation. It's like using a coupon at a grocery store. |
Why can't you leave a baby alone? | It? Nothing. Which also puts it at a lot of risk if say, your house catches on fire. Or if it does manage to roll over or get a limb stuck in between the crib slats. And yes, you are going to say 'but I am only at the store for five minutes', but you cannot guarantee that. Something might happen at the store that cause... |
Using multiple TV screens to display a single image. | Source: ~8 years doing various digital signage stuff, including video walls > For example, 9 TVs set up in a 3x3 grid, working together to display one large image. In this case they wouldn't be TVs so much as monitors, typically purpose-built for video walls. > Why aren't they all just displaying the same image? How do... |
Do flocks of birds have 'alphas' is there a sort of hierarchy amongst them? | I don't thinks so, to my knowledge flocks of birds do not have a dominance-based hierarchy. They will rotate to fly in the V formation to save energy and switch out the front bird once they are tired. It happens pretty much automatic, once the front bird gets tired, it gets slower and someone eventually becomes the new... |
Most animals lick their fur to clean it. So, how come they don't get their mouths full of fur which would be extremely annoying and uncomfortable? | Yes, they do. Cats vomit balls of fur every now and then. Their tongues are different than human tongues and probably don't *feel* it as gross and annoying as you imagine. |
LSD and other psychoactive drugs are known for their visual hallucinations. What would happen if a blind person were to experience these hallucinations? | It would depend why they're blind. LSD plays with the thalamus, the part of the brain responsible for deciding which signals go where. If someone had a functional visual center and damaged eyes, they would experience vivid daydreams of visual phenomena that aren't quite as realistic as sight. If they have a damaged vis... |
The Reality of Gravity Versus The Sensation | We don't directly perceive the deep physical reality of *anything.* We can't see that light is photons. We can't tell that heat is vibrating molecules. We can't feel that digestion is acids dissolving our food. We can't tell that an electric shock is electrons. It's no different with gravity. We perceive what our body'... |
Is washing dishes under hot water (but cool enough not to burn you) actually more sanitary than washing in cool/cold water? | The simple answer is yes. By raising the temperature, you kill off bacteria that only thrive at lower temperatures. However, the practical value of this isn't all that significant. Unless the heat is quite high and the dishes are exposed to the heat for a longer period of time, you won't kill all the bacteria. |
What is "summer reddit"? | During summer Reddit sees a big influx of kids and teenagers who would otherwise be busy with school spending more time online because they are sitting around home bored all dayYou know how there's the saying on Reddit of "Never go full retard"? /r/SummerReddit points out all the places where Reddit went full retard. |
Why is it that when a word is is repeated in a sentence our brain ignores it? | For effect, OP really should have duplicated a word in the question.for much the same reason we can read [this] we don't actually read every word in a sentence 1 by one, we're trying to pick out meaning. since the extra word contributes nothing, it isn't registered. |
What is the subreddit r/circlejerk all about? | To put it like you're 5 The term circle jerk is used to describe a group of people who *compliment* and *praise* one another for sharing the same opinion or idea about something. |
Why do you feet sweat more wearing just slippers than if you wear socks and slippers? | You shouldn't be. But you're probably noticing it more because socks do a really good job of absorbing sweat and drying. |
Why do we only name an element after it is synthesized when we knew it could in theory exist? | The idea is that whoever synthesizes the element first gets to name it. A bit of a "reward" for "winning the race" on getting it together, really.Well, according to IUPAC, a new element is only considered an element if at least one if it's isotopes has a half life of greater than 10^ seconds, an half life simply isn't ... |
What is the structure of the entire internet? | The entire Internet is made of two things, endpoints and midpoints. Things like your computer and the reddit server are endpoints. Endpoints have an IP address assigned to them, and logically one connection to the network represented by that IP address. Midpoints have multiple connections to the network, and pass packe... |
Why is alcohol consumption such an important part of our culture? | Alcohol has been in the human culture for a long long time, think of way back Jesus, before Greeks even. Alcohol is a depressant, so it helps to socialize and forget things that causes anxiety. |
How to people survive from falling at such great heights? | It's not the fall that kills your, it's the sudden stop. Usually the people who survive these falls land in something that slows them down relatively slow, such as shrubbery, snow, or mud. Based on the article, it appears that this man landed in the latter and also on top of someone. edit: looking into the story a bit ... |
Who really is running North Korea? | It's really unknown at this point. The general consensus is that Kim Il Sung had a pretty tight grip on things, Kim-Jong Il had a lot of influence from the senior generals, and that Kim-il Sung is kind of a puppet to those generals. Again, it's all speculation, since its one thing that intelligence agencies can't know. |
why is undercooked chicken more dangerous than undercooked beef? | I saw this question answered before. Chicken is very porous so bacteria has a lot of little places to hide in. Beef is not so less bacteria stick to it. This is my Eli5 version.I'll take a shot at this: 1. When you eat chicken, you very rarely are eating a smaller cut like a steak. Because the majority of your meat was... |
Why Samsung can make HBM2 when it was first made by a different company? | Samsung has a huge manufacturing facility. Other companies make the designs and the prototypes of the technology, but then they need someone to produce it in mass numbers. They send the design to Samsung and tell them "I want so many thousands of this", and they make it. Even Apple's mobile chips that are Apple-designe... |
How come I can buy stuff from China on amazon that costs less than $3 with free shipping? I don't understand the economics | There are three reasons: 1. There is a difference in economies. You have to earn five times as much here to get by financially. 2. The Chinese government subsidizes shipping. 3. eBay and USPS brokered a trilateral ePacket agreement with China Post that gives China bulk shipping rates at a rate far below what we have to... |
How it was determined that the stars we see are actually distant suns like our own. | [/r/askscience] is the best place for an accurate answer to a question like this. I am not sure what the first evidence was, but one thing, we now have the ability to analyse the light light coming from the stars. It is exactly the type of light we would expect from a sun undergoing nuclear fusionFrom [here] > In 1584 ... |
Why there's no form of textpost karma on Reddit | Because the people who care enough to write thought-provoking discussions probably get more reward from the discussion than they would from imaginary internet points. Whereas the kind of person that posts meme links is the kind of person that gets a real kick out of getting their internet-ego stroked by the shiny shini... |
How is it possible that a washing machine can spin so quickly (1200 rpm)? That's 20 spins in a second..? | > ELI5: How is it possible that a washing machine can spin so quickly ? That's 20 spins in a second..? That's not even fast! A blender can spin at 18,000 RPM All you need is a properly built motor that's strong enough and good bearings. The motor just needs to be able to overcome the drag at that speed and should be bu... |
Why do computer screens make ripples when I put my finger on them? | LCDs, use liquid crystals, which were first discovered in 1888. These crystals are actually liquid chemicals that align perfectly when subjected to electrical fields; when they're properly aligned, they allow light to pass through them. LCDs use this property by using electrical currents to align the crystals and allow... |
Why hasn't anyone/won't anyone take militarized action to secure the Ukraine crash site and investigate, with so many countries having had citizens who died in the MH-17 incident? | There are a lot of politics involved, and very large consequences for any military unit violating another nation's borders. Countries may not want to start a war for the sake of a few dozen people. Additionally, military action isn't something that can happen overnight. Supply lines need to be generated, mission parame... |
When we get sick, why does our throat randomly get sore overnight? | Normally your body does a good job of getting rid of your everyday bacterial infections. You might have several colonies of harmful bacteria thriving inside your body but you won't even notice. However, when your immunity system is busy dealing with a widespread viral outbreak, like the flu, bacteria might take advanta... |
Where does cremation come from and why did it get so embedded with the Slovenian customs while being so rare in other countries? | [Cremation is Pretty common in both Europe and the US.] Not sure what you are talking about. For example the rate is 75% in the UKCremation has been common in many different cultures, including much of Europe. But it fell out of practice as Christianity spread because the Catholics and Orthodox variants of the faith be... |
Why do many black women have much fatter asses than any white woman I've ever seen? | West Africans have a more curved femur than whites or Asians. Most black Americans are of west African descent. This is why they jump higher and are faster sprinters. East Africans are the exact opposite with straight femurs, Obama for example. This is why they dominate in distance runningGenetic tendency toward [steat... |
How do martian rocks end up on Earth? | Something really big hit Mars, blowing the rock free and it fell down to EarthSo there should be earth rocks on mars? |
What happens to the sound wave energy when it hits a vacuum? | Sound waves are moved by one particle hitting the next and losing its energy to it. The particles keep passing this energy along, and that creates the energy transfer of the wave. When you helmet vibrates, and all it finds on the other side is vacuum, there's nothing to lose energy to, so it keeps it. A vibration is tw... |
Why do I have difficulty walking on to a broken escalator? My mind just won't treat it like stairs. | It's called the [Broken escalator phenomenon].I think a big part of the problem is the change in step size. Ordinary-stair makers are wise to be careful to maintain a uniform step height throughout and select from a ergonomically comfortable range. Lots of thought has gone into stair design. |
Why people of Jewish faith have been persecuted throughout history when they share similar beliefs to Christianity and Islam? | I 'd argue that this sub isn't for comprehensive understanding and more for explaining things broadly. You might want an r/askhistorians explanation. [Here is a good thread] Basically they are a distinct minority. They stand out based on their customs and practices. They are conspicuous. They are sort of insular. Both ... |
That effect when in bed almost dozing/dreaming you suddenly feel like stumbled and the falling sensation hits you hard with a jolt of adrenalin. | That's called hypnagogic jerk, IIRC. Basically, the hypothesis is that it's caused by your brain misinterpreting the sensation of your muscles relaxing as you fall asleep. It thinks for a moment that you're losing balance, so it goes to correct it. Your conscious explanation of this automatic response is "I felt like I... |
The other day I drove by a speed radar sign. The sign was showing a slower speed than my speedometer was showing. Which one is more accurate and why? | The radar detector is likely to be more accurate. For two reasons: Your speedometer actually measures rotations of your drive shaft or something directly linked to it, so it presumes that your tires are the same size as those used by the manufacturer to establish the speed, if you've changed brand, tire dimensions, or ... |
When we started running out of ipv4 addresses, why not just make "ipv5" with 0.0.0.0.0 through 255.255.255.255.255? | That's effectively what IPv6 does, only it skips straight to using 0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0 to 255.255.255.255.255.255.255.255.255.255.255.255.255.255.255.255 . The problem is simply getting all the existing equipment in the world upgraded to understand IPv6 to that we can start using it everywhere.Your computer... |
Why do TV shows and films often have their characters using fake social media websites/search engines on screen? | It is considered advertising and there are a few reason they avoid it. 1) It being advertising they want to be paid for it. Most will not pay so they make imitation products. It is the same reason they invent soda or beer brands, and why apple computers will have the apple logo covered or altered. 2) If the product is ... |
The more I read, the more I wonder: How the hell is Clozapine in Pregnancy Class B when it's considered such a dangerous medication? | All antipsychotics cross the placenta. Unfortunately, unmedicated schizophrenia in the mother poses a greater risk to unborn children than antipsychotics. Also, in both animal studies and human surveys, clozapine is not shown to be teratogenic . _URL_0_Class B means that animal studies have not shown a birth defect ris... |
what's the difference between voxel and point cloud based graphics? | They're essentially the same thing, points in a 3D space like you said. Voxels are generally thought of as the "pixels" of a 3D grid of known dimensions, say 512x512x512. Like how pixels are a unit of a 2D grid. Point clouds are generally used is a world space of undefined dimensions, like cm or mm in XYZ as floating p... |
Gorillaz and their virtual band "history" | Huge Gorillaz fan here. I'd rewrite it but since this question is asked a lot by fans, it can be solved by a simple google search. Backstory before the band 'got together': [here] Condensed full storyline before and after: [here] |
If an education is supposed to help you in life, how come people complete it knowing it will cause you lots of trouble down the road? | I don't understand your question. Education doesn't tend to cause problems down the road. I can't think of a time when I thought "dammit, my life would be so much better now had I been less educated." EDIT: OK, it seems you're asking about student loans, not education. Well, it's because the benefits outweigh the downs... |
Why are there only a few major television networks in the United States? What does it take to start a new one? | I take it that you are thinking about broadcast networks. There are plenty of amazing, big and new networks in the cable and online space. Over the air networks are difficult to establish because the network must recruit local stations to be affiliates. There are only a small number of local broadcasters available beca... |
If a RAR or ZIP file just make another file/group of file smaller, then why could we just keep compressing those RAR/ZIP files to make any file we want extremely small? | It only makes things smaller by removing certain types of redundancy. Once those redundancies are removed, they're removed, and trying to find and remove them again will get a 0 result. Here's a simple example of compression to help you visualise it. Imagine that we have a novel that reads like this: > Jennifer collect... |
What happens in the long run if for every 5 days I skip one night of sleep and continue to sleep the same amount of hours for the rest of the days? | I did roughly this for about 2 months. I gained 25 lbs. It's important to note that I wasn't eating very healthy and was averaging 4-6 hours of sleep per night the rest of the week with one 9-12 night but that was true for months before and after missing the one night's sleep a week and I didn't gain weight before or a... |
what does "cyto-toxic" and "cell-toxic" mean? | Cytotoxic simply describes something that destroys or interupts the function of a cell. It can describe a chemical or another cell. "Cell toxic" means exactly the same thing. The previous cyto means cell. |
Why do things appear to move slower, when they are much bigger? | A 1cm-long fly moving at 1 m/s covers 100x its body length, per second. A 15m-long bus moving at 1 m/s covers only 1/15 of its body length, per second. In other words, they seem to move slower because your brain is measuring their speed in terms of how large they areIf you are talking about things already in motion, th... |
Why aren't "season tickets" to your favorite bands a thing? | I can't speak for everywhere, but the bands I would subscribe too aren't in my area more than once a year, and when they are - it's part of a bigger concert. I would much prefer to just buy tickets on the fly, for flexibility and the economics of it. |
Why do Catalonia and the rest of Spain think each other are poopie heads? | Let's start at the beginning. In the year 711 a Berber general crosses from what is now Morocco into Spain and starts conquering. In the years that follow, Muslims conquer most of Iberia . From roughly the year 800 onwards, Christians start conquering back Iberia, and in doing so start several different countries with ... |
Who chooses where the Olympics are going to be? | The Olympics is run by the International Olympic Committee, which is made up of members from almost every country. There are currently 106 members from around the world. Each time they need to pick a new host, interested parties put forward their bid and the other members vote on who should win. Bidding to become the h... |
How do computer board designers change and update parts like GPUs and motherboards to be compatible with all types of new and old standards, and make them faster, so quickly? | In a word: Standards. If your part doesn't comply with the standards for that part, it won't work with anything else. Which means nobody will buy it. New standards are sometimes backwards-compatible. Sometimes they are not - so part manufacturers don't *always* make stuff compatible with everything else. Add to that th... |
