Why are flights directly to a major airline hub more expensive than flights elsewhere that connect through that same hub? | That's so bizarre! I did the same search just now, and the craziest part is flight 5005 from Madison straight to Detroit is $400+ and the flight to Miami that uses 5005 as a connecting flight is $209. Could you just book the Miami flight and miss your second leg? As long as you don't check a bag. And you'd get more fre... |

How are tanks used on a modern battlefield, and aren't they sitting ducks? | There have not been a battle between two modern armies in a long time so it is hard to say.

Aside from being able to perform harder music, what makes someone a good percussionist? And what differentiates the absolute best from the "just good"? | Percussion is most of all about rhythm, and rhythm is much more complex than the perfectly uniform timing that a drum machine puts out.

What's Colbert's point or plan in creating his Super PAC? | If I remember correctly, it was originally supposed to force the FEC to make a decision whether to allow Viacom to support a political candidate unconditionally.

How does bandwidth of networks keep increasing? How can we squeeze more speed from the same cable? | One way is through multiplexing: Say your basic signal is at 100 MHz, that would give you 100 Mb/second. Then, say you add another signal at 200 MHz, that would give you another 200Mb/s. In order to do this, you have to combine the two waves mathematically to create one new complicated wave using a [Fourier transform.]... |
Why do so many shows make their seasons only ten episodes long these days? | There might also be something around the quality of actors being used. Recently, we have seen top quality actors shift from movies to television. More A list actors are getting into television. These actors are also still making the occasional movie.

When I squint at a bright light, why do I see small bars of light coming out of the lamp? | It is because you are seeing the seams in your eyeball. Same as if you look at a light through a pinhole in a sheet of construction paper.

Why is our first instinct to studder and say uh/um when we are trying to explain something or present. | They're basically subconscious conversation managers. When we know we're coming to a slight pause in conversation to collect thoughts and say something else, we use "uh" or "um" as a cue to let the listeners know there's a break in our speaking. Otherwise it 'd make for an awkward and confusing silent break. As for get... |
Why Laptops and phones get slower with age | Some operating systems purposely update themselves to a newer version and this leaves the older device crippled.

After that ... |
Why didnt the US intervene in when Russia Invaded Ukraine the same way it intervened when Iraq invaded Kuwait? | Russia is several orders of magnitude more dangerous than Iraq.

Why is the orientation of the earth the way it is on maps, globes and images? | It's just a convention, as far as I know. It wasn't always the case - many maps from the middle ages have unusual orientations, like the [Gough Map] of the British Isles. The fact that map-making civilisations tended to be clustered in the Northern Hemisphere, plus the primacy of the North Star in our culture, made the... |
Why are computer viruses created? | Sometimes to sell anti-virus software. Sometimes to steal personal information to be sold. Sometimes because people are just dick holes. Sometimes because people want to demonstrate vulnerabilities in systems to gain employment by that systemThey are created to profit. Think ransomware - cryptowall 3 supposedly made $3... |
Why can't phone service providers offer spam filtering in the same fashion that email service providers do? | Because the phone companies wouldn't make money. They buy and sell on a per minute basis of a connected call. Filter out a spam call? That's a few minutes of profit not earned. Email providers don't charge per email, just a flat rate , so they don't care if they deliver a spam message or not. |
Why do I always have nightmares? | As someone who has nightmares, though not to a degree that concerns me, I can tell you that real-life, everyday worries and concerns are the main cause for all of my really bizarre horror movie nightmares when I have them.

It's one of the first really odd things you have to wrap your head around... |
Why does there seem to be such a social stigma against banking with credit unions? | I've never heard of any stigma for banking with credit unions All I've ever heard is people praising them.

why can we fly and land planes in rain and generally bad weather, but shooting a rocket into space can be delayed by minor weather/rain? | Try keeping a broomstick vertical on your finger, you need a lot of corrections to keep it steady, right? Now go outside and try to do it on a windy day. How much do you have to move your arm to keep it straight? A rocket is unstable and you can't burn a lot of fuel to correct for winds, it means it will run out of gas... |
When the U.S. sues banks and lenders like Fannie Mae and such, where does the money come from? Isn't it all lost? | I'm confused?

Does cardio training(eg: running) help with sustaining intelectual effort (studying) for longer amounts of time? | No I don't think so. It does help a bit though if you take a break from studying to work out or go for a walk. Exercise is a good diversion and also gets the blood pumping. You can't really say that active people in general are smarter or better students though |
Why are there no currently produced 5-seater convertible cars? | A car manufacturer is only going to produce a car if it thinks it has a market, it is a waste of money to make something nobody wants. No source for this, but I don't think the market for a 5 seater convertible would be too large. Convertibles are fast and fun, and can be two door and 2 seat. 5 seat says family and saf... |
How is it possible to survive 40 years without sleep (Paul Kern)? | I do not accept the claim that Kern lived for 40 years without sleep. There are documented cases of sleep deprivation causing mental disease and death after a much shorter amount of time. In fact, there's a family in Europe with an odd genetic disease which causes some members of the family to simply stop sleeping in t... |

- Does a charged battery weigh different than a discharged one? | Nope. Batteries don't lose charge, and thus don't lose electrons. What they lose is electrical potential. Batteries are constructed by separating two ionic materials with a thin insulator between them. By connecting them to an open circuit, the electrons act on that potential to move to the positively charged material ... |
If cat saliva is antibacterial, why do they suffer from tooth decay and gum disease? | Bacteria have adapted to live off sulfur in boiling water, a cat's mouth is easy to adapt to by comparison. It's warm, wet, and frequently contains food - so yeah, something definitely lives there. That said, there's not a lot of funding for feline dentistry research so it's not very well understood. Cats don't have th... |
That computer that programmed a chip that was 'impossible' to understand. | [Article Found Here] So we need to start at the basics. Dr. Thompson got some special chips called "Field-Programmable Gate Array" . These chips are special because their own internal logic is variable rather than fixed. That means that this chip can become a modem, or a voice-recognition chip, or one of hundreds of ot... |
Why do planets have atmospheres? How do they form? | A planet forms it is pretty much just a collection of matter in a relatively dense area in space. This mass just keeps gathering more matter until you reach a size one would classify a planet. Now basic physics tells that heavier stuff like heavy metals goes to the center of the planet and the lighter stuff like gases ... |
Why can't Southern California City power companies handle sporadic high temperature usage, but other major cities handle constant high temperature usage without issue? | Spikes in consumption are much harder to deal with than constant high consumption. Think of it this way: if your power is coming from a huge collection of power plants and 100 ton spinning turbines , it's a lot more difficult to get those things going really fast to meet a demand spike than it does to just build a few ... |

Why the L.A Metro is not portrayed as much as other underground systems in movies? | The L.A. Metro only has a handful of underground stations, the rest are above ground. New York and London each have *hundreds* of underground stations, while L.A. has maybe a dozen. Also related to that, in New York and London you can get *anywhere* in town using their subway system. In L.A. it only serves a few neighb... |
What is the dot/shape in your vision after looking into a light or the sun? | The light-sensitive cells need a little while to regenerate before they can detect the next photon. If all fire at the same time in a spot, you basically have a "hole" in your vision for light, or the color you looked at, until the cells recovered.It's called afterimage. Basically the receptors in your eyes get tired i... |
What is a superfliud? | _URL_0_ ---- Superfluidity is a very special state of matter where a liquid can act very strangely. Some of the things a superfluid can do is: * It can flow extremely easily.

Objectively, the constitutional framework aside, why is the system of states choosing the president (the electoral college) better than tallying up everyone's individual vote? | It is designed to not let big states' interest control the entire election. The top ten states control just over 50% of the population despite being 1/5th of the nation. Yet 46% of the electoral college. So it's still heavily in favor of the big states. No individually california is 13% of the population while it's onl... |

There are a lot of complex biochemical process that go into breaking down various drugs, and sometimes our bodies just get rid of them before having completely metabolized them. Also, so drugs break down into other different biologically active substances that then get removed as waste.It really depend... |
Einstein's Theory of Gravity | There are many was to think about this, one way is via the gravitational differential, that is, how much gravity changes over a very same distance. When gravity is very very strong, it will also change very very very fast think about hovering just a few inches over a black hole, your feet are almost touching it by your... |
When I rest my head up against a mirror, and look down. Why can I still see reflection from parts of the mirror that aren't actually coming into contact with the mirror? | This is hard to explain without pictures, but i'll give it a shot. So this is how mirrors work: when light hits you, its reflected off into the mirror, which bounces back into your eye, so you see yourself, right? Now light is hitting you at an infinite amount of angles and reflects off of you into the mirror at an inf... |

As light moves over distances some particles begin bouncing off of air, get bent by dust, etc. This means that the farther away the object, the fuzzier the light. When you squint you reduce a small percentage of that fuzziness by making the s... |
Why are there so many different types of torrents for one episode of a TV Show? | It would be pretty bad if there was only 1, no redundancy. What if that person or group didn't upload this week?

Why is there such a large amount of rain falling across Australia, when it is meant to be an El Nino year and be very dry? | El Nino is the summer part of the phenomena. In winter it becomes El Nina and brings more rain. I would guess that in the southern hemisphere the season are reversed. |
Why is the James Webb telescope so much better than Hubble, and will it do anything different? | for starters, the Hubble is 24 years old now. We have come a long way in telescopes and related technology that lets us take better pictures. Hubble also was had manufacturing errors when it was launched, so it never was as good as it could have been. The James Webb telescope will also not orbit the Earth, but be sent ... |
how can you hear a voice or music playing in your head when it's not actually playing around you? | How do you remember things? Basically you think of something that is related to it and then your mind is 'replaying' it.

How do they shoot scenes of people being blown up or suffering severe trauma? | Either with CGI or practical effects/special effects makeup or a bit of both. You wouldn't believe how convincingly a skilled makeup artist can make someone look like they're have a *really* bad day. Do a quick image search on special effects makeup and watch some videos of it being put on, it's pretty interesting stuf... |
How does FPS change from 30-60+ create weird bugs in games? | I can't speak to this game specifically, but a common reason for things to get weird with changes in framerate comes from the way games generally handle time tracking. You've probably heard of 'ticks' - a 'tick' with respect to a game is 1 unit of time as far as the game is concerned. Exactly how long that unit of time... |
What is so bad about being near the center ("eye") of a Hurricane? | There's a hurricane all around you. Edit: Oh, and hurricanes are more powerful near the center. |

There's a few around Britain and I think North America, which shows that they visited those places. Primary evidence can be used to back u... |
Why is it with all the advances in digital technology does "on-hold music" still have the broken, terrible, staticky, playback quality it did in the 1970's? | It's because of the audio fidelity of telephone networks, which is garbage. That has to do with a combination of backwards compatibility with a hundred year old system and lack of competition among telephone providers so there's no incentive to make it any better.We could. But no one has successfully brought that to ma... |
Why do men feel better if they straiten their legs when they have an orgasm? | As with the others, I've never heard of this. I admit that I tend to stretch them too, but not because it 'feels better', though keep in mind the tightening of muscles does have a psychosomatic value of feeling more intense. There *is* science to having better orgasm with socks on however. But you're not talking about ... |
