Why do computers store negative numbers as complements to their positive counterpart? Rather than a byte specifying the sign? | The math is easier to implement that way. Say you have -1 and 1 to add. Stored in two's complement form -1 is FFFF. Add 1 and you get 10000, or 0000 ignoring the overflow. You don't need to do anything special just because one of the numbers is negative.What jawbonedbrain and piorn said is correct. In addition, it's no... |

why is quantum teleportation not getting funded as much as it should,especially with successful experiments where we teleported 1 atom/photon at a time? | Short answer to the last question: not even close. Quantum teleportation of a single particle or atom is one thing, but there are really really a lot of particles in a bunny or even an amoeba. The information content of a ladybug is staggeringly huge. There isn't enough computational power to do it. If the entire unive... |

how did the word "gross" end up with so many different meanings? | The basic [idea] is that it all comes from an original meaning that was something like "big." But that sense of big was flexible. So, in some usages it went from meaning big to meaning too big. That sense of too big came to refer also to the elements that made something up and to the thing itself. So a very fat person ... |
Why can't/don't laptops use cell service? | > Why can't/don't laptops use cell service? Some can and some do. There is a cellular card available for most kinds of laptops. The issue is that in order to connect to cell towers there is a specific kind of antenna necessary, decoding hardware for the kind of network, and of course an active cellular plan to get serv... |
Why do so many people have such a hard time being corrected or admitting they didn't know something in real time during an argument or debate? | Because they are trying to win, not trying to be right. It is normal human behavior. If there is one piece of pizza left, and we are both hungry, we are not going to have a principled discussion about who needs it more. We are going to try to persuade each other to back off, and any logic we apply to that discussion is... |
Why can't every mobile device that's capable run the latest version of Android, but virtually every capable PC can run the latest version of Windows? | PC evolution has been very slow for the last 5 years.

How was Pangea possible? | Imagine a large sandbox, but instead of sand, fill it with clay, or some other material that keeps it's shape fairly well, but can be shaped, and doesn't let water through it.

Why did the man who jumped 25,000 feet without a parachute have to land on his back when he landed? | When he hits the net, his body folds in half as the net draws tight around him. Which way does *your* waist bend?Putting the whole spine thing aside, would you want to fall into a net face first going 100+ mph?This is the same way stuntmen land on airbags or other landing spots when jumping from great heights.

How can sandbags be so effective at retaining water and preventing floods, yet when I try to make a moat for my sandcastle at the beach, the water vanishes instantly? | You don't wrap your moat with fabric.. The "bag" part is important. The grains can easily be moved, but if they're held together, it is a densely packed material that slows water movement quite a bitConsider the soil environment where sandbags are used to control flooding, it is totally saturated with water. The soil w... |
Why doesn't Egypt restore the Pyramids or the Great Sphynx like they do with paintings and statues? | They do: * The Sphinx's head and paws were repaired.

How can strongmen pull planes/trains with only a rope, sometimes with teeth, even though the objects weigh numerous ton(ne)s? | Well, they're *pulling* the weight: not lifting it. They only have to overcome the static friction in order to get the object moving, then once it is moving they just need enough force to keep it moving. [Here] is a website with an example of how much easier pulling is than lifting: a 1500 kg car can be pulled with app... |
Why would i eat a variety of foods to reach my recommended intake instead of just the one that provides the most of it. | Foods provide multiple nutrients at once, and in differing amounts. You need *all* the nutrients, so if you just eat something *extremely* high in vitamin C, you might be missing out on many other nutrients. If you then eat those other foods, you'd be getting *over* your recommended daily intake of vitamin C. In the ca... |
Is it possible for canines to be right or left "handed"? | my lab/pit mix always offers her left paw when I ask her to 'shake' my rat terrier mix always does things with her right paw, like fluffing up her blanket or trying to get a toy that's stuck under the couch.

If they... |
Left/Right handed: is it genetic or does it happen by chance? | I believe the current view is that it is a mixture of genetics and environmental factors, eg hormones in utero, birth stress. There was a [large twin study] that estimated that about 26% of the variability was down to genetics and the rest to environment. [This book] cites work showing that if both parents are RH there... |
What has come of the Russia/Crimea situation? Is the Crimean peninsula now part of Russia? | It's not over yet. Russia now controls the Crimean Peninsula *de facto*, which means "in fact" .

That would be the equivalent... |

Why does it seem like every movie is the "#1 Movie in America"? | There's usually a stipulation in their #1 rating. Usually its " The current #1 < insert genre > in America".One movie will say that they are the #1 grossing movie in America. This is probably what you are thinking of - highest ticket sales.

Why, when I'm drinking and it "goes down the wrong pipe," does drinking more seem to help? | I'm quite a few beers and a bowl deep, and too lazy to google, but with a recent degree in biology, I'm going to just swing for the fences.

With no atmosphere to propagate a shock wave, are explosives in space actually even lethal? | The gas from the explosive itself will propogate a pressure wave a short distance, but range will be severely limited by the extremely low ambient pressure.

why are certain string instruments fretless and how on earth do you play notes on them with any accuracy? | I played violin for 8 years.
