What is fire composed of? | I've found that Richard Feynman's explanations of such things are perhaps the best placed ones. He has a enthusiasm that makes the topic much more accessible enjoy. _URL_1_", 'Admittedly this was designed for 11 year olds, but [this] is an excellent explanation of what flame is. |
The difference between procedural generation and random generation | Procedural generation is a form of random generation; except that when you say procedural generation, you expect that there are more rules than just randomly putting any set of results together. An example of procedural generation would be map generation in games like Civilization. If it were completely random, you wou... |
Why are some paintings that look like a bunch of random blotches and lines given such praise? | It's a lot like jazz. A jazz musician is not reproducing a bit of music to an exact standard -- they're improvising, adding flourishes, and sometimes leaving the melody behind altogether. They succeed by demonstrating that their original work can be as pleasing as something pre-written, or by conveying something unique... |
How do movie illegal movie streaming site like movie2k, couch tuner, etc manage to even survive and make money? | A) They do not host the content themselves. They just provide links, which in itself is not illegal B) They work out of countries which do not have the same law enforcement standards. This is how it works: While most countries have the same anti-piracy and copyright laws, they don't get enforced equally. For a US-based... |
If humans are so much smarter than cats and dogs, why can we potty train our pets in much less time than a baby? | It's generally frowned upon in most social circles to be seen rubbing your baby's face in its own mess ", 'in addition to all the posts about big heads + small hips = early birth, i would like to point out that very few people have succeeded in training their dogs or cats to take off a pair of pants before relieving th... |
Why are school buses still built the same as the always have been? | Since I last rode a bus in the 70s, most now have : Automatic transmission Stop signs as well as flashing red lights Powered doors White roofs to cool down by 15°F Crossing arms to keep kids from crossing so close the driver doesn't see them Many have: Internal video cams External cams to catch light runners 2 way radi... |
How are "in-shower body lotions" at all effective? | Good for you for questioning BS when you see it lol. Just marketing. Same as how women's shaving cream and razors have 'moisturizing bars' despite it being in contact with the skin for like 0.5 seconds. It's just another beauty product trying to make money. Save yourself the trouble and apply a dab of coconut oil AFTER... |
How bad actually is it to plug in and turn on a freezer just after moving it? (People say wait 24 hours before turning it on) | If the food is already frozen and coming from another freezer, go ahead and toss it in, along with a bag or two of ice. Even an unpowered freezer is well enough insulated to act as an ice chest for a day. Also, if there's enough food to mostly fill the freezer, it'll bejust like your freezer has lost power for a day .I... |
Proof by induction and strong induction. | Proof by induction is like dominoes: you show that the first domino falls down and you show that each domino knocks down the next one. Let's take the proof that the sum of the first n odd numbers is n^2 as an example. This is an infinite collection of facts, one for each n. In this case, we can simply verify that the s... |
How does an ECU tune on a car engine affect the performance of the car? What happens? | I've searched tha seven seas fer an answer. Yer not alone in askin', and kind strangers have explained: 1. [ELI5: If doing an ECU remap on a car increases performance and fuel economy, why don't car manufacturers just do that before it leaves the factory? ] ^1. [ELI5: What is an ECU and how does it work? ] ^1. [ELI5: W... |
Why do rabbis suck babies penises when performing circumcisions. | It's a very specific branch of Judaism and they do it because tradition is more important to them than the safety of the babies in their care. About once a year there's a news report about a baby in New York City who gets herpes from the procedure and dies from the infection. |
Why do we still have circumcision? | In very special specific cases, it is done for medical reasons. But 99% of the time, it is cultural/traditional. People do it because it is commonly done in their part of the world. It's only really done in the US and certain Muslim countries though. In most of the world, it's fairly uncommon. Don't assume that just be... |
Why did everyone decide paper money should be rectangular? | Triangles require cuts in 3 directions. Squares and rectangles only require cuts in 2 directions. Now if you think about it, squares require more cuts than rectangles, because you don't have a long side and a short side. |
Why people from hot climates of Earth evolved to have darker skin. Wouldn't that make them hotter? | When ever you are out in the sun your skins pigment, melanin darkens to protect you from the sun damage that would occur without it. Over a long period of evolution people in hotter climates developed more melanin in their skin cells to protect their skin. I've had a few black friends who have complained of being extre... |
What is the legal basis for US CBP to detain a Canadian citizen at the Canadian border if there is no evidence of illegal activity? | Sometimes they can do exactly that. The mayor of my city quite famously did this recently when flying to Chicago. He withdrew the request to enter the USA, apparently after finding out he wouldn't be allowed to enter, and flew immediately back to Canada. As for their authority, there are two reasons. In most cases, onc... |
Why are murderers/violent criminals given multiple life sentences? | They are usually convicted of multiple crimes, or multiple counts of the same crime that each carry a separate penalty. As to why it's significant that they were convicted of, say, 4 life sentences rather than just saying *a* life sentence, there are two reasons. One is that some of those convictions might be thrown ou... |
I never watched/played pokemon. Why are those team rocket people trying to take Ash's Pikachu? Can't they just catch one for themselves? | When Team Rocket first wanted to catch Pikachu, they were defeated by it and realized it was unusually powerful. Team Rocket's objective is to rule the world with Pokemon/Make money off of them, so having an extremely powerful Pikachu is valuable to them. Training a captured Pikachu from the wild can only go so far. |
Why does the NYSE have Floor Traders in this day and age? | I've been told that it's pretty much just a show at this point. The small number of people that you see today make a nice background for a financial news program on television.I used to work in cbot building, commodities exchange in Chicago but same similar scenario. Camera access at exchanges are heavily restricted in... |
Why can I see the Moon during the Day? | Imagine you're standing in a field. Behind you is a large fire, but you're turned 180 degrees from it. You have a friend who is in front of you, but off to the side a bit and he's holding a mirror. You can see light from the fire in the mirror. That is seeing the moon lit up at night. Now change position. You're now di... |
What is the largest known individual object in the universe and how you can understand it's true scale? | Depends what you call object. The largest structure we know of is the ~~[large quasar group] : a group of 70 quasars~~ [Hercules-Corona Borealis Great Wall] that span several *billions* light years. It's so stupidly huge that it raises questions about the universe being as [homogeneous as we thought]. |
Why does water turn white when frozen? | The white is the impurities in your water - dissolved gases and ions. When chilled properly , the crystal structure should be fairly even - there shouldn't be many cracks. In an ice tray, water freezes from outside side in. The first ice crystals that form are almost pure ice, pushing the impurities into the centre of ... |
If humans don't naturally drink milk as adults, and neither does any other adult animal that I know of, why is it important that we have dairy in our diets? | No other mammal continues to drink milk past childhood, it's actually a rather recent development for humans too . But to answer your question, milk is not something you absolutely need to have. You can get the nutrients in milk from other places, for example there's actually quite a lot of calcium in broccoli, without... |
Why do broadcast networks require cable subscriptions for online viewing? | Because they make more money from cable subscriptions and advertising. They believe, true or not, that it's more profitable to encourage people to buy cable subscriptions than it is to try and get advertisers to pay for streaming advertisements. Notice that you may see more commercials per break on cable than Hulu or C... |
Why is Windows 8.1 Considered the 'Worst' Microsoft OS? | It's not. Windows 8 is significantly worse than Windows 8.1. I have not used ME but based on all reports, it is by far the worst OS ever released. Not worst Microsoft OS, just worst OS at all. |
How do fridges work? How can energy be used to make something colder than it's surroundings? | Fridges rely on a thermodynamic process known as a [Heat Pump.] A quick overview of how they work however: 1. Electricicty from you wall outlet runs a compressor pump. This compresses the refrigerant fluid, creating a hot fluid at high pressure. - Remember when you compress a fluid, it gets warm. 2. This hot fluid at h... |
The human body produces enough heat to bring half a gallon of water to boil in 30min, what do our bodies do to produce so much heat, especially when idle? | Most of the energy a human needs is consumed by all these constant processes that essentially make you alive what you call 'idle'. Heat produced by these processes is sort of a by-product that is useful to a degree as they need a certain temperature to work well: Is the temperature too low and the processes are kicked ... |
How did we decide peppermint was the smell of good breath? | Another comment talks about the digestive properties of peppermint. That's not just an association, it's a helper of good breath. When your tummy is happily moving things along, less odours are gonna rise up and out. I ~~don't know~~ looked up the science behind it, but mint also has a cooling sensation on the mouth. T... |
How does Tylenol "break" a fever? | A fever is induced by a illness but is an example of a positive feedback loop I.e the effects of the fever intensifies and prolongs the fever until the original stimulus is no longer present . Via the mechanism the other comments have explained the effects of the fever are inhibited for a temporary period, breaking the... |
Why is it when I take a road trip the "going" portion seems to take longer than the "coming back" portion even though it's the same route and distance? | For me, it's two factors: 1) I often drive faster on the way back. 2) If I have never been before, or rarely been before, I pay more attention on the way. If I sm driving I am focused on getting the directions right and if I am a passenger, I am anticipating and wondering what the place will be like. This forces me to ... |
How is carbon dating done and how can we know if it's reliable? | Every element is defined by the number of protons in the nucleus of its atoms. There are also other particles in the nucleus, called neutrons. So, one atom can have 6 protons and 6 neutrons and be a carbon-12 atom. Another atom can have 6 protons and 8 neutrons, and still be carbon-14. The atoms with the same number of... |
if Apple Watch only works with Iphones, what is the point of it? | I think right now smart watches can be thought of just beginning to take the first step into a new generation of devices. They're too small to get any kind of real hardware built into them, which is where the need to have it tethered to a phone comes from. In the future as SoCs become more efficient, and their power dr... |
Why were people more afraid of nuclear warfare in the 1980s? | I think I get your question. The reason there was such a fear of nuclear war in the 80's was that we had a cowboy in the White House who liked to talk tough and had a clearly defined enemy. Don't get me wrong. Ron Reagan made Americans feel bad ass again. Watergate, Viet Nam, and all the crap that we went through in th... |
What is a T1 and how it relates to my Data and Phone? | The long and short of it is that T1 connections are legacy internet connections that was popular back in the day because it allowed for 24 digitized voice channels or 1.5Mbps throughput. Most companies still using a T1 do so because they either don't know any better or because they feel they have no other options for v... |
Fluoride in drinking water. Why should I care? | To add to swordgeek's answer, which I think is ample for the purposes of ELI5, the Centers for Disease Control have a page devoted to the topic of water fluoridation. They even have a [FAQ].This is a little biased toward the anti-fluoridation side but this lists the concerns pretty well. [Here you go.] |
when does an act of self defense turn into assault? | In America you are allowed to use reasonable force to defend yourself. Two main points: 1) Reasonable force: this standard accounts for several factors that may be considered by the police, DA, and jury. Factors such as relative size difference, martial skill ability, environmental factors, weapons, intent of the attac... |
How did prostitutes manage contraception before modern methods? | Moon Tea were early forms of contraception, but if that failed, and you were subjected to pregnancy, you most likely would have a bastard child as it was unacceptable amongst nobles. Your child's last name would then be claimed by region: Flowers: The ReachHill: The WesterlandsPyke: Iron IslandsRivers: The RiverlandsSa... |
I want to learn about Tor (network). | 1. Does the Govt Keep a record? Probably but unless you are planning a nuclear attack, they don't care.2. Virus? Your chances of getting a virus are the same for the regular internet. TOR only masks where you are from. Having proper system security and antivirus protection is your own responsibility.3. Sites? Start wit... |
Why do people (and apes in general) have two breasts/nipples, given that they're most likely to have only one child at a time? | I'm not positive, but I have heard that mammals have twice the number of nipples as their typical litter size. That way, if you have *more* than you expected, twins for example, you're still okay. |
Why do dogs that know me still bark at me? | They're not barking at you. They're warning your landlord that you're coming home. He's trained them to do this because he likes to sift through your underwear drawer and try a few on while you're out. He closes his eyes and sways dreamily in front of your mirror, often while listening to light rock on his old walkman.... |
Can someone ELI5 the difference between a Will, Trust, and an Estate? | Estate just means all of a person's possessions when they die, before they're distributed to heirs. The precise definition can vary, so that the estate for probate purposes might exclude things like trusts or payable on death accounts, for which the probate court doesn't have the same control over its distribution, whe... |
Why are we always told to make sure someone doesn't swallow their tongue when they go unconscious or have a seizure, when it isn't actually possible to swallow our tongues? | If the person is unconscious their tongue will relax and fall back to close over their airway if they're on their back. That's why we're taught to put an unconscious person into the recovery position. Maybe the phrase comes from this idea? |
why is kitty litter dangerous for humans (particularly pregnant women) but does not harm the animals that use it? | Many people are confused about this and spread wrong information. Cat litter and the dust is NOT unsafe. What is unsafe for pregnant women is a parasite that MIGHT be in the cat's poop. It is only in the poop if the cat has been eating mice infected with it.. and the woman would have to get it on her hands then put her... |
How hard is it for a sniper to shoot a moving target? (I'm thinking Kennedy) | It depends on distance to and speed of the target. At relatively short range you'd really only have to compensate for the movement of the target . But at long ranges a whole plethora of factors come into play. You have to account for the movement of the target, the amount of time it takes for the bullet to get there, b... |
Why can the doctor be over a half hour late when I'm the first appointment of the day? | Depends on the doctor. If it is a private practice and your doctor doesn't do rounds at a hospital, then there is very little excuse for it; however, many doctors have responsibilities outside of outpatient appointments that can run-over into their outpatient time. |
How old cartridge games before discs could save gameplay progress | The earliest ones couldn't save games, as the cartridges were simply ROMS. Some later consoles had some non-volatile memory in the cartridges. NVRAM was expensive but you don't need much of it to save a game. |

She is associated with Athena though, and was held in the hand of the statue of Athena at the P... |
Why is the SCOTUS chosen by the Senate and President and not the American People? | > Aren't most matters brought before the court about issues that arise when the senate and pres can't agree on something? Not that I know of. Most of the matters before the Supreme Court arise because a law - written and ratified by the Congress and President - is challenged as unconstitutional. > Why wouldn't the Amer... |
What are the key differences between Hillary Clinton and Bernie Sanders? | Hillary's top donors are wall street businesses. Sanders is supported by most unions. This means big business thinks Hillary will look out for their interest and unions hope sanders will protect the working class. |
Why does soda from poorer countries like Mexico and India come in nice glass bottles, while it comes only in cans and plastic bottles in the U.S.? | In India the glass bottles have reduced. You can only find them in restaurants or places where you drink it and givethe bottle back. You don't find them in departmental stores where you can take them home. All places where you can buy and take the drink home have moved to either plastic or cans. They started with 2 lit... |
Why is it so common for europeans to speak english as a second language? | I always feel ignorant that I only speak English , but what other language is as widespread and useful? When I travel I'm embarrassed I can't speak the local language but they often speak perfect English as well as their native tongue. Even in Hungary I hung out with two Austrian guys, an Indian guy, a Mexican and a Po... |

She's a dangerous machine now. She's a mama. |
Difference between DC and AC | Batteries supply direct current . If you put a digital voltage meter on a AA battery it would read somewhere around 1.5 volts and would continue to read around 1.5 volts until the battery starts to run down. If you reverse the red and black leads from your meter it would read around -1.5 volts. If you stuck your meter ... |
If the brain lacks nerve endings for pain, how do we feel headaches? | There's a layer of tissue between your brain and your skull. It feels pain. Your brain does not. |
Paging and segmentation in Operating systems. | Since a programmer often can't know the exact addresses its program will use in memory, segments are used. Usually there are segments for the data, the code itself, the heap, the stack, A segment is indicated with a base , and an offset compared to this base. The goal is that the programmer now only needs to know the o... |
What's the reason for nuclear plant smoke stacks having a concave shape? | The shape of the towers creates a natural chimney effect that allows for a lot of cooling without needing fans. If you don't have the big cooling tower shape, then your towers need tons of fans to do the same cooling. These towers are to cool the water used in the condenser to turn the plant steam back into liquid. Onl... |
Why do diabetics prick their fingertips for blood instead of other areas? | It can be done anywhere, I'm not diabetic but I do use blood testing for glucose, ketones and other things that I need to do in clinic, and I'll let people have it taken wherever they like, as long as I can get the lancet there. My DM1 friend used to often do it on her arm when her fingertips got too sore, and one time... |
Why can't diesel electric trains go faster much faster than 130 mph? | Speeds above about 125 mph start to require exponentially more power. Since diesel-electric trains carry 100% of their power generation on board, they become very heavy above this speed range, and it's just much more efficient to use offboard generators . |
Why are minutes and seconds comes in batches of 60? and not 100.. or 50? | 60 has more factors. You can divide 60 into equal portions of 1, 2, 3, 4, 5, 6, 10, 12, 15, 30, or 60 minutes. That's 12 factors. If an hour was 100 minutes, you would only be able to divide it into equal portions of 1, 2, 4, 5, 10, 20, 25, 50, or 100 minutes. That's only nine factors.60 is divisible by every one of th... |
What is the Difference Between a Motel & Hotel? | as mentioned, no legal definition. hotels have hallways. motels don't. service wise, typically motels don't offer meal services.I don't think there's a formal, "legal" distinction. "Motel," which is ostensibly derived from mashing "motor" and "hotel" is a type of hotel with minimal amenities, where the rooms typically ... |
While traveling Europe using an American credit card, why do card readers ask if I want to be charged in Euros or USD? | It's called dynamic currency conversion. You should ALWAYS select the currency of the country , and not the currency of your card , since the rates are pretty much always shitty and you'll get a better rate if you just let your credit card network convert for you .A lot of credit cards charge a couple percent foreign t... |
Why don't the top Oil producers start investing heavily into Nuclear Energy?? | It's a matter of cost. The oil companies have already invested a lot of money in oil. They are making large returns on that investment. If they switch fields, they need to now figure out how nuclear regulations work versus oil field regulations. Build expensive plants. There's a 10 year delay before you start returning... |
Why were poets of the 20th century easily marketed and made money from their poetry while poets now have such a hard time making money from it? | Poetry has never been more alive or better than right now:It's marketed as 'rap music', currently. Watch out for when the name changes again.Most early 20th century poets did something else to make money. For example, TS Eliot, arguably the most successful English-language poet of the century, was a banker for decades.... |
If people are often able to crack big security systems, such as banks' ones, or internet protocols, what makes it that difficult to crack slot machines and that kind of things? | EDIT: Read the comment by /u/ShavedRegressor. Mine is wrong. ~~Slot machines aren't hooked up to any server. They're completely independent machines.~~ ~~The randomness comes from a very complex algorithm that actually uses a time stamp that gets converted into a random number. When you pull the arm you are just creati... |
What is the difference between ethnicity and race, and why are they separate? Don't they mean the same thing? Yet the two seem to always be asked separately on job applications | Race refers your genetic makeup- you and your biological family's physical features. Ethnicity has more to do with your cultural background, like ancestry, traditions, etc. It's more about what group of people you identify with. For example, someone might be Latino but identify as Guatemalan . |
How does corking a baseball bat make players able to hit further? | A lighter bat = a faster swing. I've also heard that a cork core gives more flexibility to the bat, which makes it act like a spring, storing and returning more of the kinetic energy of the ball than would have been returned with a non-corked bat.They actually don't. The corked area makes the bat behave more like a spo... |
Why is the internet dominated by America? The most visited websites and social media services are all American. Why? | Honestly, probably because we're so aggressively capitalist. America is one of the few places with the opportunities to allow practically anyone witha bright idea and the will to see it out a shot at success. That and because so many people worldwide know English. Not that many people outside China know Chinese, same w... |
Can you actually eat other people and survive? | You can eat other humans in the same way that you can eat animals. There are parts that are good to eat and there are parts that you shouldn't eat. You should prepare the parts in a manner that prevents the spread of germs and disease, in the same way that we currently do when we cook and eat animals. |
How did single cell organisms evolve into having things like eyes which seems like one of the senses that would evolve out of nowhere? | Nothing evolves out of nowhere really. SIngle cell organisms didn't evolve eyes, multiple cell organisms evolved over a long period of time and some of them ended up having some specialized cells that reacted differently to different amounts of light. We can see organisms today that are like this. Things simple like th... |
Why are there no travel restrictions for a city in Congo where Ebola has been found? | Ebola is really contagious, but the only way to get it is by coming into direct contact with the bodily fluids of someone who is infected. It's not like you're at risk of getting it if someone sneezes next to you. It spreads in the developing world because people live in close quarters and don't seek prompt medical att... |
Why does my nose stuff up when I sit/lay down but clears instantly when I stand up? | This is just my little theory but it probably has to do with the oxygen supply in your blood. It's a little known fact the swelling of the sinuses is actually regulated by the amount of oxygen or the lack thereof in your blood. I did figure this out during a very nasty cold. I was wondering, why I could temporarily ope... |
When a company headhunts an employee from another company, how do they know how well that person is performing and how much of their companies success can be attributed to them? | I was headhunted once although I never took them up on the offer. They wanted to more than double my salary and offer me free travel to my home every weekend and a bunch of other stuff. I talked with them for a bit and one reason they were looking at me was because I stayed with my current company for almost 7 years at... |
What would be the consequence of UK pulling out of the EU? | I'm not from Europe but I was talking about this with a few of the guys I work wi who are from the UK The biggest plus that a lot of the public see is that the UK wouldn't be bound by the EU policy on refugees and asylum seekers. Countries in the EU are obliged to have a much higher intake of people seeking refugee sta... |
Why do different types of alcohol make me different types of drunk | I think the types of alcohol also encourage certain attitudes, like they have a personality of their own, if you will so I've noticed in my experience. Whiskey, it's a man's drink, a common drink among the tough guys of the wild west. That guy annoying you? Have a shot of Jack and let him know what's what . Vodka, it's... |
Why do movies use CGI when older movies like TMNT and Jurassic Park looked better and more realistic? | I think one thing that may throw you off is that some movies today may have entire scenes of *nothing but* CGI -- CGI aliens fighting CGI spaceships with CGI guns, weapons, and explosions while the main character who has a facial scar that's CGed onto his face, shoots his CGI plasma thing at the CGI villain. Jurassic P... |
Why do Teenage/Young Adult men dislike sleeping in a bed with each other when women do it regularly? | I think there's a lot less social stigma against two heterosexual women sharing a bed and cuddling, a lot of people would just think that's nice and cute or whatever. Whereas if males did the same, some people would take that to mean something different, rather than just a platonic friendship. Plus women are hot, men a... |
How did the US expand the landline phone network to every household? | One short answer is that they didn't get landlines to every house. My sister in rural Idaho, for example, had to pay thousands to the local phone company in order to get landline service. |
Clothes I was looking at on my laptop have found their way into ads on my phone. How is this possible? | Do you share accounts between your devices? Google, iTunes, Amazon, etc? Because if so, that's how. Google AdSense will recognize you on any device and target ads to you. |
Why do people still run around chaotically on the floor of the NY Stock Exchange every day? Why don't they just do it from computers in the offices? | I think, in the end, it's the difference between playing poker at a casino and playing poker online. |
What is "NoFap" and why do people do it? | It is when people stop masturbating because they think it will give them more sex drive, more confidence, It's a complete placebo and continuing to masturbate is a lot more healthy and helpful than stopping it altogether.Participating in NoFap is when an individual, usually a man, decides to go cold turkey on not mastu... |
Why do a majority of "As Seen on TV" products cost $19.99? | A lot of those infomercials use installments so it's really not just $19.99. But I also think they have a lot of people coming to them with products/new inventions and want to make an infomercial for it and they get denied because it's either too expensive or too cheap. Part of the allure of infomercials is not only th... |
Why are chemical weapons so controversial, but "ordinary" bombs acceptable? | Chemical weapons are controversial because the especially horrific effect they have on victims is thought not to correspond to any military necessity. That's why their use was restricted by international agreement; if two countries at war agree not to use chemical weapons, their military situation remains equal and the... |
How much water should you actually drink per day? | If you're thirsty, drink.If your pee looks like Mtn Dew, drink more.There are published formulas/charts that can give you an approximate numerical answer based on your weight but rule of thumb is that if your pee is dark yellow or darker, you should drink more; if your pee is light yellow or clear you are drinking enou... |
What do seniors with no savings do if they have no family? | I'm fortunate enough to live in the UK, where we enjoy what we call a 'welfare state'. This was introduced just after the second world war by the newly elected 'labour party'. These were 'socialists' but not 'communists', and our National Health Service was formed along with the 'State Pension' that was applied to ever... |
When lightning hits the ocean, why don't the fish die? | Some do. Salt water is a very good conductor of electricity, but due to resistances, the electric charge *usually* doesn't go more than 15 meters deep, if that. In terms of horizontal spread, I wouldn't be able to tell you. One other thing is that water is a better conductor than most fish, so the electricity takes the... |
If most cells in our body are replaced after about 7 years, why do we still keep some scars? | its the same reason why scars don't look like the skin they replace , the repair is not perfect .and the skin is formed from epidermis , dermis and hypodermis, but some structures move from one place to another during development. for example hair is formed from the ectoderm but then the hair root descends to the dermi... |
How does Amazon remain operating when it supposedly does not make a profit? | In addition to reinvestment, as a huge and diverse company Amazon can also play a long game where it drives prices so low that it shuts out smaller companies with smaller credit lines. Amazon can wait out six months at a loss; a mom and pop store can't. Additionally, they're building loyalty. Several years at a loss bu... |
If nuclear weapons are literally 1940s tech, why is it so difficult for nations to build them, 70+ years later? | Because most of the developing world's home grown let is not even in the 1940s yet. Make no mistake, they have a lot of modern technology, but that came from outside of their borders, because a more technologically advanced country gave or sold it to them. Since those countries don't share nuclear related technologies,... |
