As cups are usually quick smooth, the effect of friction is very low resulting in very little mov... |
Why do we find B.O. unappealing if it's something that occurs naturally (and often while we're relatively clean)? | I used to be friendly with a homeless guy who hung around outside a bar I used to frequent, and despite being homeless and looking the part, and not even setting foot inside the bar, he managed to go home with women like ALL the time. It was nuts. Some girl would step outside to smoke, or linger before leaving, and he ... |
What causes sleep paralysis in our brain? | Not exactly this, but for a five-year old, this Imagine your brain shuts down some functions when you sleep.

Why is everything so expensive in Australia and New Zealand? | Prices are higher on nearly all islands. When you cut out the possibility of trucking and rail shipment, costs go up. While Australia and New Zealand have some natural resources, they have to import more items by plane and boat than non-island nations. Even on islands that have bridges to them, the route is typically l... |
How do scientists know that Dark Energy makes up ~70% of the Universe if they don't know what it is? | The universe is expanding. That is to say, all of the galaxies that we can see appear to be moving away from the point where they all started at the big bang. That makes sense. Big explosion, everything gets blasted away from the middle. But, since gravity means that matter attracts other matter, the galaxies should be... |
Why do dogs react to human voices but not to speakers (phone, TV, music, radio, etc)? | I hate to admit it but we still have a landline. The phone and voicemail are inside the basement stairway.

Usually this is on one side of the brain or... |
How do bugs always get trapped inside ceiling light covers? | I don't have proof for this but I read it in an article about mooths. Many insects tend to confound an artificial light source with the moon-light which they use for orientation. And once they get in the lamp-housing its hard to escape for them, just like a bee flying in your room through a tinted window and then not b... |
Why do pharmaceutical commercials always tell viewers to see their ad in a magazine? Do people seriously buy a magazine just to look at an advertisement? | It's because they can't always fit all of the legally required fine print into the commercial -- side effects, warnings, etc. Take a look at a pharmaceutical ad in a magazine sometime, and you'll find that it's probably two pages, back-to-back: Pretty drug ad on the front, and page o\' text fine print on the back. And ... |
What happens to the brain when you get knocked out? What are the long term consequences? | Generally speaking, a knockout is when your brain is rattled against the side of your skull. Hence why knockouts sometimes don't happen with the strongest punch, but with a moderate strength one placed right on the chin. The leverage is better at "whipping" your head around, causing the brain to slosh around in there a... |
Humans produce lots of body oils. Would they be good for anything if they could be harvested? | This really should be how baby oil is made. From those especially oily babiesHow about as a replacement for fossil fuels? When you shower, a decent amount of body oil is washed down the drain, carried through a sewer and into a wastewater treatment plant. One of the first steps - Primary treatment - is a physical separ... |
Why is it that human intelligence evolved so rapidly while other intelligent creatures like dolphins remained behind? | Human intelligence hasn't changed much , but human knowledge has. The reason we have as much knowledge of the world as we do is our linguistic ability. Most of the knowledge an animal gains over its lifetime is lost when that animal dies because most animals have no way of communicating what they know to other animals.... |

Why are the Beatles so popular? | I won't explain why they were popular in their day, as that it obvious. The reason they are still revered to this day is because of how innovative they were. Apart from being great songwriters, they were ceasless experimenters. Never making the same album twice. Remember that a pop band writing their own songs was just... |
What is new electronics smell? | There really isn't a single answer for this as it depends completely on the product. With that said, most likely what you are smelling is the chemicals used to clean the circuit boards and such to prepare them for use.

How can I swat a fly with all my might, yet it still comes back to annoy me? | You are using the wrong technique, boy. Might will not rid you of the fly. You need speed, agility and intelligence. You don't need to crush the fly, you need to capture him. Flies are not smart, surely you can think better than him. Use your brain, not just your muscles, boy, and catch the fly.Because its near impossi... |
When is a plant considered officially dead? | I don't know that there is any official legal or technical declaration of plant death which is consistently followed. Usually individuals will consider a plant to be dead when as a whole it isn't able to recover from its current state even if some clippings may be viable. |
How come when the Reddit servers are down, they can still provide the Failure message? | The server in question is most likely the database server. When you access a page, reddit's web server needs to ask the database for the data. The database has a limited number of available connections, so if too many are currently in progress, it will refuse more connections. The web server will then get an error mess... |
How does anonymous hack into websites and how are they structured if they are all completely anonymous? | 'Anonymous' isn't really a single group, it's a generic identity for 'hacktivists'. Anybody can claim to belong, and people that don't claim to belong might get lumped in with them anyway. How one can crack into any website or network is a lot like asking how someone can break into a building: there's a huge collection... |
How do medical examiners/other forensic analysts determine the time frame in which a person died? | The liver cools at a fairly constant rate, as it is so well insulated within the body, so they measure the temperature of the liver and the ambient temperature of the room, and from these numbers they can estimate a time of death. This only works if it was a recent death, for longer times they have to take into account... |
One Degree of Separation for movie making | It means always making sure every scene is directly connected to the main plot line and main character. It is a way to trim extra fluff and bullshit from your movie. |
Why can't we do brain transplants like other organs? | When we transplant other organs, we mainly have to reconnect tubes . If we were to replace the brain, we need to reconnect the nerves which we don't know how to do on such a large scale. At least that is my current understanding.The brain is the most complex organ in the body. It takes years for it to develop uniquely ... |
How can Comcast can charge me a ridiculous price for 30mbs internet but at best I get 3mbs down or up? | Well I'm. Pretty sure you're paying for 30 MegaBits where as your download is MegaBytes .

It's in the disclai... |
Why do we remember some skills (e.g swimming and cycling) our whole lives? | It's called procedural memory. More specifically, it's 'muscle memory' or 'motor learning' which is a type of procedural memory. Your brain's cerebellum, in particular, is very good at encoding sequences of muscle movements into long-term memory storage. Procedural memory is very robust. Even people with dementia and a... |
why do only loans and credit cards show in your credit reports and not other types of accounts | Information cannot show up on your credit report if it is not reported to the credit agency.

Are internet and cable ads confusing on purpose? Or are cable and internet companies just bad at their jobs. | They are well thought and confusing on purpose:1) they don't want you to be able to compare their product to the competition. 2) they try to give a sense of urgency "buy now" even the product is on the shelves for a long time. They frequently create fake sales, fooling people into believing they get a great deal.3) the... |
How are my headphones playing a "ghost station"? | A nearby AM radio station is being picked up and rectified by the TV. A simple AM receiver can be made with a junction of two dissimilar metals or a metal needle point on a crystal. I suspect the electronics in the TV are performing the rectification and the headphone cable is the antenna.I have a couple of my own theo... |
How do interplanetary spacecraft (and in the future interstellar), protect against collisions with space debris? | They don't and they don't need to. Space is incredibly big and empty. Despite how visuals like the one on the [Asteroid Belt Wikipedia article] makes it seem, the majority of the asteroids are very small and the distance between them is enormous. The odds of our probes to the outer planets hitting anything are astronom... |
How is it possible for us to know if a sound comes from the top or the bottom given that we only have two ears aligned horizontally? | The shape of your ears directs sound into your ear canals difforently based on the angle it comes in at.

That is unless the government subsidizes the construction, w... |
If we used nuclear power for everything, how long until we run out? Could we get more uranium by then? | Fissionable materials are infinite for all practical purposes.

Here is an excerpt I found from an interview ... |
If the Big Bang happened, what events preceded it? | The honest answer is that we don't know. There are some conceptual ideas, but none with any evidence as of now.

How are highway light pole bulbs changed? | Tall hydraulic lifts with a guy in the basket. It really is that simple, they cone off the lane, the guy gets in his safety harness and gets lifted all the way up there in the basket with the new bulb.

How they determine the length of time to wait between airing a movie in theaters, and premiering it on TV. | I say once they 've felt they 've squeezed as much money as they can out of dvd sales from rentals and purchases.

If someone wants it the "industry" again get paid for licens... |

What is the difference between an originalist interpretation and a "living document" interpretation when it comes to the U.S. Supreme Court? | The idea is a debate about whether the founders wrote the thing to be specific, rigid, and amendable only through the amendment process or whether the founders wrote the thing with deliberately looser language to take shifting societal norms into account.

How does doing more exercise give you more energy? | Energy the body produces isn't a "static pool" that is only filled with so much water.

The body is getting into a mode w... |
Why do most US schools have children get up before the crack of dawn to go to school? | The American workday is typically 9-5, and parents need to get their children fed/clothed/etc and on the bus or dropped off and still able to get to work on time.Couple reasons.

How do military aircraft intercept hijacked commercial planes? | Former navy, we did flight ops with helos to intercept subs and track em. Intercept is kind of a blanket term.

Why do stovetops measure temps from LO-HI (with numbers) instead of temps? | The temperature of your cooking element doesn't really give you an indication of your food's temperature. Just because I set my stove to 200 degrees doesn't mean that the food is 200 degrees. Why not just use a food thermometer like everyone? |
Why are we able to see shockwaves? | refraction changes in air density act like lenses made out of air more or less the same effect can be observed over candles, only there it is hot air and not compressed airThe low pressure portion of the wave will cause the temperature to go down.

As such, it prevents you fr... |
How do old animated films get digitally remastered to make them HD? ie: old Disney movies. | They were always well beyond HD. Do you think the version that was sent to theaters back in the day was equivalent to SD? It was on a film reel that was even higher effective resolution than 4K for the most part. The film master is put through a scanner that saves the movie in a digital format. We have much better scan... |
how are movies like the Parent Trap made when one actor plays multiple roles and their faces are seen together in the same shot? | One way of doing it is to shoot the scene twice without moving the camera.

What is the difference between fuel grades at gas station pumps? What do the more expensive ones provide? | Higher grades of gas have a higher octane rating, which is important because octane is less volatile than cetane .

Putting down animals in zoo | Did you read the rest of the article? They explained exactly why they did it. They didn't have the money to relocate the animals, and the new animals they were getting would have killed the old animals -- euthanasia makes a little more sense than a zoo snuff show. It's more important to look at the population of the sp... |
Trademarks: How can there be a DC comics and a DC shoes? | They're in two completely different lines of business. DC Comics isn't trying to sell shoes and DC Shoes isn't trying to sell comics, so there's not likely to be confusion between customers of the two companies.

Why sunglasses makes someone looking more charismatic/elegant/cool? | Since not had any responses, a few reasons I would rationalise it down to: * Positive association - it's used in a lot of films/movies/books as a way of signalling that someone is cool. As a result it's now associated with coolness * Psychologically it might add a bit of 'mystery' to the person - you don't know where t... |
Why can't we make batteries that hold dozens of small batteries, then make high amperage chargers to charge them in seconds? | Batteries are made up of smaller batteries or cells. The problem is regardless how you make a battery, you need to deal with heat when charging a battery. The only way to overcome the problem is to spread the cells out further apart so what you have is a very large, low capacity battery. It's better to have a very dens... |
Wouldn't one third of something go on forever? | No. You've fallen into the trap of thinking that base 10 is the only way to measure things. We count in 10s because we have ten fingers. But imagine that humans had evolved with five fingers on one hand, and only four on the other. In that case we'd count in base 9, and then your question becomes simple to answer, as o... |
Why do doctors have such bad hand writing? | Here's my 2 cents from a med student's perspective. I've always found the handwriting thing strange.

Just a guessLess of your rear is being supported o... |
What causes some people to be more tolerant to extremely cold or hot temperatures? | Some of it also has to do with what you are used to. Here's an anecdote I am from the frozen part of the northern midwest. In the winter, it rarely gets above 15 degrees F, and wind chills are often below zero. I lived in this area for 13 years before I went to college in the mid-south . During the first January I was ... |
