why is glass transparent even though it's solid? | Photons pass through glass because they are not absorbed. And they are not absorbed because there is nothing which "absorbs" light in visual frequencies in glass. You may have heard that ultraviolet photons are absorbed by glass, so glass is not transparent for them. Exactly the same happens with X-rays for which our b... |
Why does windows still have non 64 bit versions? | 1. Intel's first generation of Atom processors was 32-bit only. This means that there were 32-bit processors sold until 2010. It's a bit early to cut off support for them. 2. After people complained about Vista's requirements, Microsoft decided to put some effort into keeping the system requirements low. The Windows 10... |
How do we become complacent to scents and does this happen to other senses? | Your brain doesn't feed you all the information it receives about the outside world, it filters it and only passes what it considers *useful* information onto your conscious brain and tries to get rid of anything that is unchanging which may distract you from the important bits For smells this means after a little whil... |
- Why does a community need to secure the RIGHT to create its own broadband? Why can't they just do it? | Also, the cities often don't own the poles, companies like AT & T do. Thus, the city needs permission from whoever owns them to run cables and stuff on the poles. .Because 22+ states have state laws banning or severely complicating municipal networks. The big ISPs have been busy lobbying .See _URL_1_ and _URL_2_ This i... |
Why in the hell can't a fly figure out where the open part of a window is? | Ecologist popping in, lately insects have been my thing.

Why is it easier to bend strings on guitars with shorter scale lengths? | The pitch of notes on a guitar string is altered in one of two ways.

Had a very negative reaction to an antidepressant, what happens in the brain to cause that? | **1) venlafaxine withdrawl**First and foremost, venlafaxine can be very nasty to come off of, so depending on how slow your transition was, it’s possible that what you experienced was actually a symptom of your venlafaxine withdrawal rather than the bupropion itself. I tried switching from sertraline to venlafaxine and... |
Why does getting hit hurt so much more when it's cold? | The nerves in your hand get much more sensitive when they're cold. Also, your veins constrict, and blood runs less to your extremities and more to your vital organs to preserve heat. This makes your skin more rigid, which causes pressure to be applied to these already sensitive nerves. So everything is getting less blo... |
Why does garbage always seem to have a common smell regardless of what's in it? | The smell is composed of small Nitrogen and Sulfur based molecules, produced when microbes break down organic matter. So as long as it's organic material. Because these molecules are small, they are easily blown into the air and up your nose. It does not really matter what you start out with, it all ends up as the same... |
How come some animals like dogs go in heat, while humans don't and why don't we? | The secret is we are always horny. Seriously Animal need a function to tell them to procreate.

why Google and Facebook use URL's that redirect to the desired site instead of direct links | Servers can't see what you do in your browser, they can only see requests you actually make to them.

Why can't a perfect vacuum exist? | There's no physical law that forbids it, the problem is that it's really difficult to remove every single atom from an enclosure, even if you do that, it's hard to prevent atoms from the enclosure's surface breaking off into it, and even if you do that, your space is still filled with photons and neutrinos. |
Why does London use only one type of taxi cab? | Actually, they don't. Although the famous "black cabs" predominate, there are other styles and colors.

In what ways are prop engines better than jet engines on a plane. | Those are turboprop engines. They use an jet turbine to turn the propeller. The thing about lots of thrust is that you can have a high-speed thin stream or a low speed wide stream that produces the same thrust. Thin streams can more easily become unstable, an instability is bad in a super-sized fuselage like that. The ... |
How to charge clients/get paid in general when you’re a freelance artist? | I’m a musician, and I always make sure the payment/terms are agreed to in writing before the work is done, even if it’s just an official e-mail.

Why would ordinary people donate money to a political campaign? | I'll add that "voting with your dollars" carries a lot more weight than simply casting a ballot on election day.Belief in that candidate and wanting to support them is really what it comes down to. It's a way to be engaged in civics at some level, even if you don't have much to give, even if your $30 won't help much, a... |
How do we, physically, store visual memories? Is each neuron used as a "pixel", and if so, how do we have enough room in our brain for it all? | Neurons do not just store one thing. A 'pixel,' in your analogy, would actually be represented by a specific combination of many different neurons. Each of those neurons may be used in many other combinations to represent many other pixels. And there are [around 140 million neurons in the primary visual cortex] alone. ... |
How were computer codes actually created? How can you just tell a blank system to accept a certain sequence of keystrokes to mean something if it has no software to start? | Basically the first 'programming' is done by computer engineers using electricity and various materials to move it around. By correctly arranging components you can get them to make circuits that will do math or otherwise have some useful and predictable input- > output. [You can use other materials too.] You can 'prog... |
How do they make the olympic flag fly? | They are probably using compressed air running up the flag pole to make the flag waveBlowing air on it. Simple process really, take a fan, aim it at the flag, voila. |
How does an album get leaked? | I've worked for several record labels, and the answer is pretty simple, the music just changes hands a lot from the recording studio to the factory that manufactures and packages CDs.

How do airlines determine flights? | Yes, there are indeed algorithms where you can input all the trips people want to take, and what resources you have, and get a roughly "optimal" combination out. In practice, there is a *huge* amount of manual intervention that complicates things, for example: - We 've advertised this specific flight for a long time an... |
Why do most fans have an odd number of fins? | Rotational force. The more fan blades you have greater margin of weight difference you can have per blade and the fan will still stay relatively balanced and harmonic. Think of it this way. If a 4 blade fan somehow loses one blade the entire weight of the fan will swing in one direction. since 3/4 of the sides will hav... |
Why does coffee/tea make me pee like a racehorse when drinks with 3x or 4x the caffeine content (like energy drinks) do not have this effect on me? | Its because caffeine isn't that strong of a diuretic by itself but it's metabolites of theobromine and theophylline are. Energy drinks use pure caffeine while natural teas and coffees have high theobromine content which explains why they make you pee more than energy drinks Edit to be more ELI5: caffeine makes you pee,... |
Why do cables that plug into phones such as the iPhone cable have multiple pins going out but ultimately its a 4 pin usb connection on the others end? | In the case of the lightening connector, the 8 pins aren't used to communicate with the USB port, they communicate with a chip inside the cable. That chip in turn communicates with the USB port. That doesn't answer your question, though, of why there are so many pins. The answer is because it allows the phone to work o... |
why don't the number keys on phones and keyboards go the same way | Numbers on your keyboard, and calculator a have 1 2 3 and 0 on the bottom because people who used to "calculate" things such as scientists and accountants needed to use 1 and 0 a lot. They wanted them right next to each other and easy to get to without having to reach over other keys. Phones on the other hand, the valu... |
With North Korea's nuclear testing threats targeted for the United States, why can't the U.S. or any other nation in the UN take them down while they don't have nuclear weaponry? | The first issue is China, think of North Korea to China as what Israel is to the USA. Nothing North Korea does is without permission from China. If they wished for North Korea to stop what they were doing, North Korea would oblige immediately. The Second issue is again China, in the same way that China has vowed to pro... |
Why is the text opticians make you read always reflected through a mirror? | So the chart is far enough away to be effective. If his office is only 10' across the image can be sent across the room, reflected in the mirror and would essentially be viewed by you at 20' away. |

How is Levar Burton able to use STTNG as a selling point for his Reading Rainbow kickstarter? | Which ones do you mean? Giving out tickets to events, letting people take pictures with his visor, or just saying "I played Geordi"? None of these violate any sort of trademark, since it's just him doing stuff with his personal property. If he started making Star Trek merchandise to sell, that would be different.I imag... |
the concept of "consumer surplus" | Let's say I would be willing to spend up to $10 to buy a certain product. In other words, you could say the value I ascribe to that item is $10. You could also say I would be indifferent between having $10 and having that item. If someone sells it to me for $7, $3 is my consumer surplus for that transaction, because I ... |
Why can my body handle heat or cold somedays better than others? | I'd say it's probably due to the level of humidity in the environment on any given day. If it's hot AND humid, your sweat won't evaporate and you won't cool off. |
why do Formula One races go in the rain, but Indianopolis 500 type cars don't go in the rain. | Indianapolis 500 type cars, also called Indycars, do go in the rain. They just don't race in the rain on ovals. This is because rain tires are made to have optimal grip at a lower temperature than racing slicks. On an oval the outer most tires have more loading than the inner most tires which makes them hotter and wear... |
What's the deal with carbon nano-tubes? | Well they're a relatively new invention We'll be seeing a lot more carbon nanotubing in the near future, as there are some very practical uses. They are ultra-thin and extremely strong for their width. We could use them for space elevators, as well as a new mode of transportation: carbon nanotube monorails. They're so ... |
Dogs and Cats being scared of the Vet. | I won't speculate on anything else, but the answer to your last question is that prior experiences with the vet have often been traumatic, like getting surgery or being vaccinated, which from their perspective was just getting stabbed with a metal spike randomly. It's the same thing that happens with babies. They learn... |
Why do magnets completely distort the coloration of older TVs and computer monitors? | Old CRT displays work by firing a beam of electrons through a large vacuum tube at a screen with phosphors that glow when struck by an electron. The electron beam is aimed by electromagnets in the TV, since electrons are, themselves, essentially tiny magnets. Bringing another magnet near the TV can disrupt its ability ... |
Why is it that, when I concentrate on my vision, I can see a sort of "static buzz" on everything? | Just wanted to let you know that your not crazy as I can perceive this effect too. I never really thought to much on this before as I just assumed it was something along the lines of the photon receptors in the retina chemically resetting after processing the previous photon. Now I will have to spend time researching t... |
How did humans learn to measure time accurately? | Technology has always evolved, just as you have seen in your own lifetime. Before the watch there was the clock.

the Internet's obsession with Nick Cage | Have you seen how sheep follow each other? That's how we get things like Chuck Norris jokes, jokes about Sarah Jessica Parker looking like a horse, pictures taken wearing that same old brown horse's head, Shrek is life, and obsessing about Nic Cage.

The most widely held view, the Helmholtz theory, says the ciliary muscle contracts, causing the lens zonules to slacken which allows the lens to spr... |
Explain to me like I am five if you could, why timing and rhyming with words feels so good. | First off, it's probably highly culturally and linguistically relative. In some languages, like Japanese, for instance, there are a lot of regular patterns at the ends of words for grammatical purposes, so it is trivial to rhyme in Japanese, such that rhyme gets shut out as a poetic and musical device. In English, wher... |

If all cells are made of lipid walls, what stops two cells from blobing into one when they collide? | It's because cell membranes aren't just made of lipids, they're made of **phospho**lipids. Phospholipids have the typical hydrophobic fatty acid tails that other fats have, but at their head, they have a very hydrophilic phosphate group. Stick a bunch of these phospholipids in water, and they'll naturally group the fat... |
Shares, Stock, Accounts, Monopoly..... | I think I can answer some of your questions: 1) A share is a percentage of a company. The word stock is sometimes used interchangeably with shares.

How come people in Africa are starving but there are uncontacted tribes in the amazon who are surviving just fine? Why cant the starving people in Africa do that those tribes are doing? | I would wager it has to do with location and population as well as land that others won't allow access to for free.Well the sheer volume of people needing fed for a start. Also you are comparing a lush green area, rich in clean water, to an often barren and dry land.Resources and climate changes. Any population needs e... |
Why is task manager more effective and faster rather than pressing the X or alt + f4 when something freezes? | Because being able to end a program that won't exit by normal means is one of the features of the Task Manager.
