Why are there basically no red or blue stars in the nightsky? | Because red-shifting and blue-shifting are really only noticeable on scales far beyond what your own senses can accomplish.

Can dogs make sense out of electronic picture such as a TV showing humans or a Skype call with a human they're familiar with? If not, why not? | From my experience, it seems that some can but most can't. Ditto for mirrors. If you think about it, it's kind of weird that humans *can*. Your screen is just a flat surface with blobs of color. The fact we can *see into* a flat surface and our minds create the perception of a 3D space is weird, and almost completely u... |
Why do we board airplanes front to back instead of outside-in? | Purely efficiency-wise, yes, a combination of back to front and outside in is best. But there are class overlays of course. In first class, you can board whenever. If you're already at the gate, why not board, get situated and have a pre-departure drink? Some people like to wait and board last, and that's their option ... |
How do Bar and Qr codes work | I don't know about QR codes, but Bar codes are just numbers. black lines on white backgrounds are really easy for computers to identify , much easier than actually reading "numbers".

Why people (usually teens) pretend they are not interested in someone when they really are? | When revealing emotion to another person, we become vulnerable to their response.

Why do I flinch at 3D movies? What makes me think that I have to avoid something? | Well, all your nervous system has to go on is the image on your retina.

Since your spinal cord controls reflexive movements, you flinch, because the neural impulse is quick, and doesn't get processed b... |
What are the biggest differences in the sound between 48000Hz and 192000Hz sampling in terms of hearing? | Sampling rates or bit rates? Those are different. From a signal perspective, 40 KHz is all the faster you need to sample to perfectly reconstruct the audio. This is from the [Nyquist-Shannon sampling theorem], which states that you only need to sample a signal at double the highest frequency of the signal. Since audio ... |
Private sector investing vs. Public sector investing. | If you mean stocks it's as easy as it sounds. Public stocks are created and advertised on a public stock exchange where anyone can buy them.

Many high end routers have a built in USB port, which you could plug a hard drive into, allowing you to access that device over wifi. A higher spe... |
Why can animals like Sudan the Rhino interbreed with family members and be genetically sound when humans can't? | because there is no other option to continue the species.

The effects frictions have on the space shuttle during re-entry | Friction doesn't have much of an effect, it's the compression of the air below the craft that causes a huge amount of heat as the air particles are forced together.Friction does add some heat during re-entry.

Antenna Extensions. Like a telescoping antenna on an obsolescent cell phone, or the controller for an RC car. How does the small increase in length of the antenna affect its functionality? | There are two things about antennas you need to know: * The minimum length of an antenna is based on the wavelength it needs to pick up or receive. Longer is usually better.* The shape of an antenna does not necessarily have to be long and straight - it simply has to be a certain total length to be effective. FM radio ... |
Why can you stare directly at the sun when it's setting, but can't when it's high in the sky? | I've never learned this myself, but if I had to take a guess I would say that it's because during a sunset the light from the sun has to travel through a longer stretch of atmosphere before it gets to your eyes, because it's hitting the atmosphere at an angle now, as opposed to during the day it's more of a straight sh... |

why can't the Hubble space telescope capture images of planet surfaces? | Galaxies are really, really big. As it turns out this is all mathematically determined: > The ability for a telescope to resolve an object is, as you’d expect, directly related to the size of the mirror or lens. There is a simple relationship between mirror size and resolving power: R = 11.6 / D. What does this mean? >... |
What is Political Science? | Political science is not a real science so sometimes the title is confusing.

People tell me to let my faucet drip in cold weather because "moving water doesn't freeze". Why, then, do rivers and oceans freeze? | Okay I'm at work, so this will be quick.

Theoretically water's boiling point should be 202F at 5,330 feet yet it boils at 206F in my kitchen. Why? | That temperature is to do with standard air pressure so either the air pressure is higher where you are or your thermometer is out of calibration. Also, that temperature is for just water, if you are in an area with hard water, the boiling temperature will be a little higher. It's also possible that you're wrong about ... |
Why don’t image hosting websites like Reddit or Imgur constantly get sued due to all the copyrighted images that people host or post on them? | This is a teeny bit long so for the super super short version read the TL:DR at the bottom.

Why doesn't Italy seem to get the same share of responsibility for World War II as Germany or Japan? | I think it's mostly that Italy did so shittily in WWII that they never really invaded much of anything else.

Certainly, there would never be more live he... |
