How are buildings over 2,000 ft in height structurally safe?
It's mostly about how they are designed. Back then before computers were this powerful and available, you weren't able to simulate how the structure would fare under conditions such as wind, earthquakes, the ground it will be built on, and how the building will act being under its own weight. Nowadays, we can easily de...

If toxic and edible mushrooms are so easy to confuse, then why are poisonings from market-bought mushrooms so rare?
1. They're not so easy for *experts* to confuse.2. Most of the ones at markets are farmed, not found in the wild.3. Most of the popular market species aren't the ones that look very similar to poisonous species.Edible muschrooms are cultivated in mines, as standard and regulated as any major food production industry
Why is Agnes Martin (subject of today's Google Doodle) considered a great artist?
There's really nothing mysterious about art, although it tends to irk those people who want to quantify everything. Granted, there's been a lot of philosophical debate over what constitutes art, high art, etc, but what I'm going to cover here is pretty much uncontrovercial. Basically art works like this: we as people e...
Last year ExxonMobil made 486 billion dollars, Walmart made 443 billion, BP made 375 billion. Where the hell does this money go? Scrooge McDuck's money bin?
Running their businesses. You are looking at revenues, not profits1mfa0 is right, those numbers are revenues, not profits. However, your question is still valid. Companies like these make huge profits and the money does pile up over time. They have four options and they use all four at various times. * Let the money pi...

Why are objects in my car mirror closer than they appear? What's the point of that?
if your side-view mirror was a traditional flat mirror, you wouldn't be able to see very much because of its small size and distance from your eyes. Instead, a convex mirror is used, which means it is curved. This allows you to see a greater field of view, showing you more of the cars that are off to your side and behi...
Why do electrical companies want you to conserve energy?
1. the electrical company makes much of it's money selling you access to electricity and only some in charging for actual electricity.

Do we see differences in intelligence within species of animals as large as those seen in humans?
I'm not sure how many studies have been conducted, but simple answer is yes. There are smart and dumb animals of the same species, breed, etc. I have known two dogs of the same breed, raised in the same house and one is as dumb as a brick, the other figured out that if he wanted to jump the electric fence, the insulate...

Why do people care about karma? What's the point in being a karma whore?

One, it feels like yo...
Why are presidents who are giving speeches not afraid of getting assassinated?

How did humanity assign words to things? For example, why was the brain called 'brain' and not some other word?
It's all completely made up. That's as simple as it gets. When we talk about translating between languages it's really just looking at the same thing and finding out what word Chinese people made for it, etc. By the way, your name was completely made up too.You're deep in language theory. For example, _URL_0_ Many thin...
why does John Wayne refer to people as "pilgrims" in his films?
Not the kind we think about this week, with the turkeys and the buckles on their hats. Pilgrim just means a person on pilgrimage -- a religious voyage of fulfillment and redemption. More generally, it means a wandering traveler from a distant place, or just a foreigner. Wayne uses the word "Pilgrim" to refer to eastern...
. Why do we experience DeJaVu?
The ELI5 version of the most believable theory I've heard is, the brain has a glitch and stores new memories in an old memory slot making it feel like you experienced it in the past.As it was explained to me, and forgive the fact that I am just a normal person not a neuro-specialist, there are two basic kinds of memory...
Why is there a stronger breeze coming from my window when the door is open as opposed to closed?
You're allowing greater airflow. With the door closed, inflowing air just piles up in your room, and quickly reaches a pressure that stops much more inflow. When the door's open, there's no such bottleneck.
Why does your body gasp for air when exposed to sudden contact with freezing water? It seems a bit counterproductive to inhale when wet (e.g falling through a frozen lake)
It makes you breathe in quickly because you are potentially about to be entirely submerged in cold water so it makes sense to take as big a breath as you are able. This typically won't occur if your head is the first thing to enter the water.> it doesn't make much sense that your body would make you gasp for breathe wh...
why do you have to sign after using a credit card at some places and not others?
It varies based on store policy really. Some places require a signature if it’s over a certain dollar amount. Some places require a signature period, and some don’t care at all. It’s just a matter of what they want to do. I can go to Walmart and don’t have to sign if it’s under $50 but if I go to the local tobacco stor...
Why internet providers (like Verizon now) are throttling certain websites and streams
Simply because they can. The FCC hasn't set out a good guideline for internet providers to follow. This lets them throttle and speed up certain "high paying" peoples.
Why does it not take long for money to be taken out of my account, but if I'm getting money from PayPal or something similar, it takes days to process?
The way it works is like this. When you make a bill payment or a purchase, let's say the money is going to Apple, the funds are taken from your account and put in the Apple account at your bank where they are kept until they are processed. These funds are then sent in a big chunk to Apple at some predetermined time eve...
Why is it that the hot water is the left knob and cold water is on the right knob for sinks?
Simple. Because the majority of people are right handed, and will reach for the tap with their right hand first. It is safer and more practical to turn on the cold tap first. As a left hander, I hate you all every time I am half asleep and scald my hands.
Every human on the planet spontaneously vanishes, and a hundred years later, aliens arrive. Would they be able to find out about the internet?
Sure, there would be an "Internet for Dummies" book someplace on a library shelf. They could learn all about what the Internet was. They could go to the places where the computers were, and maybe fix up the Wikipedia servers so they could learn all we know.Unless they were TRULY alien in some extreme and spectacular wa...
what exactly causes pins and needles and what's the best method of getting rid of them? Are some people more prone to pins and needles
Pins and needles are caused by nerves which have been deprived of blood supply by pressure "waking up" and complaining about their previous condition. The best way to avoid them is to avoid putting them under such pressure in the first place. Probably some people are more susceptible to the sensation due to their body ...
From an evolutionary standpoint why do human babies grow temporary teeth only to be replaced later by permanent ones?
We are not the only species that has that. I know dogs and cats do, too. I think I remember reading it's about size. When we're small our jaws don't have enough room for the big permanent teeth we end up with. We still need teeth, though, so we get little mini-teeth. Then, as we grow older they get replaced with larger...
Why do we look up when we are thinking?
It has to do with how we access memories and thoughts. Our eyes unconsciously look in certain directions depending on your thought process. Every hear someone say they can tell if you're lying by your eyes? It's often because of the direction your eyes look before answering. For example, looking up and to the left is g...
A deer can eat poisonous plants like rhoderdendrons because they don't have a gall bladder. When a doctor removes a humans gall bladder, are they too able to eat poison without feeling ill?
It depends on the 'poison' you're talking about. A lot of toxicity in humans is caused not by the chemical itself, but by what the liver breaks it down into. For example, ethanol is converted to acetaldehyde in the liver while isopropanol is converted to acetone. One of these is 'relatively' safe for us to consume. The...
Why are generic alkaline batteries not as "good" as name brand alkaline batteries?
Cheaper materials, usually, or because they intentionally made them hold less charge so they'd sell more of the name brand version. A better question is why you are using alkaline batteries in the first place. You can get a rechargable for only a little more that holds just as much charge and is reusable.
What happens to our feces in the sewers?
Vice had a nice video about [this]. Slightly NSFW I guess, contains a lot of fecal images right from the start. In short, it gets separated from water and other stuff, like toilet paper, gets tested if it doesn't contain poisons or dangerous material and is dried and made into a compost.Generally it first meets a pump ...

why can we just pump water into deserts to solve rising sea levels?
The surface of the oceans across the world is about 500 million square kilometers . To reduce the level of the earth's oceans by one millimeter , you'd have to pump five hundred thousand cubic kilometers - or about 120000 cubic miles of water into a desert AND THEN KEEP IT THERE and don't let any of it evaporate or it'...
What is the purpose of human beings having emotions?
Almost all animals have some level of emotion, whether it be how we interpret it as emotion or simply forms of communication. It is a sort of communication - If someone doesn't look happy they tend to show it . The emotions we have, although sometimes annoying, help us be closer together and understand one another. Eve...
How does an inverted switch 12v dc to 110v ac? Where does the extra 98 volts come from?
Some of the inverters use a circuit called boost converter, a boost converter uses solid state switches to charge an inductor. When the power to the inductor is removed, the collapsing magnetic field generates a higher voltage. To make it AC some inverters use multiple boost circuits and switch between them, if you see...
Why is it not safe to freeze food that's been frozen and thawed once already?
I believe it actually is relatively safe - the problem is more with it's quality. Freezing forms ice crystals, which puncture and damage structures in the food . Doing it once can be a problem , doing it twice is twice as bad.
'The-Dream wrote Umbrella by Rihanna' — what does that mean?
[The-Dream] Is both a producer and a performer. In this case, he wrote the song- all Rihanna did was sing his lyrics. In pop music the majority of music is created this way. The producers craft the actual song and the "stars" do little more than look good and sing what they are told to sing.Yes, The Dream literally wro...
Why do we always portray extraterrestrial life as way more advanced than us?
Yes, but primitive life wouldn't find us. The only way we would find primitive life is if we advanced enough to search for them. Edit: it should be noted that loads of sci-fi presents ETs that are less advanced than we are.
- What are "3g", "4g", and "4glte" and how are they different?
Think of it like roads or highways. 2G is like being on a two-way dirt road, no matter what kind of car you have you're limited as to how fast you can go.3G is like having a paved two-way road, because of the nice pavement you can go a lot faster than you could with 2G, but it is still limited by traffic.other networks...
I understand why it takes so long for our bodies to 'wake up' after we finish sleeping. How come it takes so long for our brains to be fully operational in the morning?
If you wake up naturally - that is, you wake up without an alarm or an annoying parent, then your brain is pretty much ready to go. But if you are in a deep sleep and something external wakes you, then your brain is still asleep and needs time to wake up. That is, unless you get the person to wake you with something lo...
Is the steam that comes out of nuclear power plants irradiated?
> But then that means the water comes into contact with the uranium in order to be heated? No. There is a fluid that passes through the reactor to pick up the heat and then passes through a heat exchanger which transfers the heat to the actual working fluid that turns the turbines. The steam going through the turbines ...
Why does your eye sometimes go black when your standing up?
Your blood pressure drops because your body was optimized to move blood around while you were lying down. Quickly changing position causes blood to drain from your upper extremities lowering your blood pressure. This causes a brief dizzy spell occasionally.
If an electrical outlet (120 volts) can kill you, how come a taser (50,000) can't?
ELI5 version: Voltage is like the speed of a projectile. Current is the weight of it. A pea from a pea shooter may have the same speed as a cannon ball, but the cannon ball will hit harder. So, the taser can deliver a lot of voltage, but not much current. So, basically, it's a pea shooter with an extreme muzzle velocit...
How come having a shower in the morning magically stops me feeling like trash?
Hey friend, this is just speculation on my part, but I would guess there are a combination of things going on here. I completely know what you mean - I *hate* waking up early. But the shower makes it a bit nicer. Partly it is just a nice feeling, to be clean, and feel the warm water. Moving around, and the sudden chang...
Do skeletons of similar sizes or shapes have different masses? Can one be "big-boned?"
There can be small differences in bone structure. Generally not enough to be statistically significant. Sex, race and occupation can all play into general bone weight. As far as people carrying extra weight being "big boned" as a reason. No, they are just eating too much and exercising too little.
Why is the new My Little Pony show so popular?
I'm still not sure if a big portion of the internet is fucking with me", 'I think it was one of those "ironic to like" things at first. Especially since the internet following is mostly adult males that claim to be "bronies" and bros liking little girl things is comical. But, once you watch it, it's actually pretty wel...
Why is it that AA batteries can have a small form factor and hold 2700mAh while my phone battery is huge and stores less?
mAh or mili Amp Hour isn't a measurement of energy. Amps measure the amount of electrons flow per second, but does not take into account the "Pressure" behind those electrons Energy is Amp Hours X Volts. Volts is the "Pressure" behind those electrons. AA batteries are either 1.5V or 1.2V, while the cellphone batteries ...
Why is it that when I get a cold, I feel cold.
Your hypothalamus usually tells your body to be around 98.6 degrees . That's what your thermostat is set to. If your body is less than 98.6 degrees, you feel cold. Now when you get a fever, your hypothalamus tells your body to get hotter, so it sets the "thermostat" to 102 degrees or so. So now, if your body is lower t...
what is the correlation between light being refracted in a lens and also slowing down within the lens?
They're not unrelated at all, the slowing down of light is what *causes* the bending. They're both described by a property of the material called the refractive index.
If I eat a huge breakfast, can I be full for the whole day?
No, you cannot be full for the day. Feeling full has to do with blood sugar levels being over a certain baseline, hormones released as you absorb nutrients from your intestines, and your stomach being physically filled. You will process food out of your stomach within 1-3 hours and total digesting between 6-12 hours de...
- Why do Cuban-Americans actively lobby against US-Cuba relations?
Most of them are from the population which was forced to flee or expelled from Cuba when Fidel Castro took over, or have since escaped. Their big thing is that it is still the Castro's in charge of a still very much communist and unitary political party system of government.The big guy in Cuba threw them out. They want...
How many mega pixels are our eyes?
It's not really an answerable question - the human eye and the interpretation of what is seen by the eye in the brain don't act like a camera. Although we do have a certain number of photo-receptors in the eyes that can detect light of different colours we can't just use that as a measure because often enough some of t...
Why does food or drink sometimes randomly irritate your throat, prompting a coughing fit?
It happens when you try to breath and swallow at the same time. There is a flap of skin called epiglottis that prevents food/liquid from entering the trachea. When the swallowing and breathing don't sync up well, a particle of food *might* stick to the epiglottis, causing you that irritation you feel. Cough is a natura...
ELI14: Pornhub vs. Youporn vs. Redtube vs ...
The best part of being a default subreddit is that finally new questions are being asked. Thanks, OP.A lot of the tube sites were started independently of each other and then bought up by one company . As to why they kept the original names, I'd imagine it has a lot to do with SEO , in addition to some market saturatio...
What's the big deal about Jackson Pollack?
Great art is not a competition about who is the most skillful. To most non-artists, they tend to associate great art with great skill, and in some cases this is true , however, art is subjective by nature. And many "eras" in art were started by a single artist that have the vision to see a different way of doing someth...
Why do dogs bark violently at other dogs when you walk them?

Why does Forbes consider someone like Bill Gates "self-made" when he grew up in wealth and could afford to attend Harvard?
Because the money he has is money he made, himself, through his business. It isn't money he inherited from a family member or something.

What is a Master's Degree and What Does it Signify?
Elementary school - is general. You learn what everyone else learns. High school - still general.

Masters - ok, now you're an expert and people would acknowledge that you rea...
How can we keep growing seedless mandarins if there are no seeds in them to grow more?
Most trees are not grown from seed. Most trees, particularly commercial fruit/nut trees, are grown by snipping a stem from a highly desirable tree and rooting it or grafting it into a desirable root stock. These trees are clones, rather than new genetic mixes. For example, if you plant an apple you won't get an apple t...
Why do clothing manufacturers make female pants without pockets?
For various reasons, women's fashions have favored appearance while men's have been more about utility. That has led to the use of lighter fabrics in tighter fitting cuts, where pockets, especially occupied pockets, would lead to unsightly bulges. In part because of this, most women carry purses, rendering pockets less...
Having an intensely realistic dream that wakes me up via my heart is beating out of my chest.
I'd be a little concerned actually. Heart beating out of your chest while waking up from a dream probably means you have sleep apnea. I'd visit a sleep doctor. It's a serious, but easily treatable condition. I'm not kidding about that.
Why does African Americans are seen more likely to vote for democrats than republicans?
Yes, in the pre-Great Depression days in the South blacks voted Republican and whites voted Democrat because of Republicans part in the Civil War as well as the fact that the Republican Party was founded on abolitionism. When FDR was elected he put a lot of money into social services. Blacks in the South had been reali...
Why do you go noseblind to things you smell all the time but not eyeblind to things you see all the time?
Going nose-blind has evolutionary basis, and scents that are 'normal' to you get filtered out so that you can smell new things like potential dangers . You can't really go eye-blind to things like spreadsheets because you're consciously attending to them. What that means is that you're paying attention to them and focu...
How come in aquariums the predators don’t gobble up the prey? Are they trained not to do so?
Many fish will only attack when they are hungry, or won't attack fish they the don't recognize as food. A good aquarium will be curated to take both these into account, and will only contain well fed, mutually compatible species.
Is pre-historic worldwide flood actually plausible?
A worldwide flood is highly dubious. However, remember that to ancient people, the "world" was very limited to their local area. Any number of floods could have inundated thousands of square miles of land, leading people to believe that nearly the whole world was underwater[This] is a map of what the world would look l...

Why do hammer head sharks have hammer heads? What is so evolutionarily favorable about that? (Not trying to argue evolution, I'm a biologist)
I saw on TV that it aids in finding fish. Sharks and other fish can detect electromagnetic fields in water, which are created by an animal's heartbeat, brain, etc. Somehow the hammer shape increase the accuracy of this. [citation needed]
Why do antihistamines make me so tired? And why does it effect others differently?
Many of the common anti-histamine drugs work by blocking histamine receptors in your body. Basically, it stops chemicals that would cause an allergic reaction from reacting with your body. However, a lot of these drugs also cause other chemical receptors from working correctly. The one we care about here is called *ace...

Why do people still use handkerchiefs
People with bad hay fever have near constant drainage. This basically water. The handkerchief doesn't even get crusty half of the time. When your nose is constantly running, the cost of tissues gets ridiculous. As for sanitary, I keep a bottle of hand sanitizer in my purse explicitly for this, but frankly, my hands get...
Why does mint taste the way it does? Mint is such a unique taste that it's more of a sensation than a flavor. What gives it "cooling sensation" properties?
Mint has a chemical in it, called menthol. Menthol chemically triggers the cold sensitive receptors called TRPM8. TRMP8 is what produces a feeling of cold. So, when you eat mints, you trigger those cold receptors that give you the feeling of cold.
Why is it so important that I finish my course of antibiotics? What happens if I don't?
Some of the bacteria survive. And because you didn't kill them all the way, they adapt and become more resistant to antibiotics. Then they keep spreading and soon we have more bacteria that's resistant, and eventually antibiotics stop working and then a lot of people get really, really sick and die. No, this all won't ...
why does drinking coffee make me slightly nauseous and hungry?
Coffee is very acidic. Consming acidic foods on an empty stomach can often lead to gastric pain and/or feeling nauseated. Adding milk or cream can help.
