why flood waters from South Carolina be shipped by truck, train, or pipeline to drought stricken like California. | 1. where does the pipeline start? sure SC has a flood now, but normally they do not have an abundance of water.

Dyson sphere power transmission to planet | The answer is basically that once you have that level of space engineering the idea of living on planets is mostly out of the question.

Why doesn't the human eye have to do this but camera sensors do? | Cameras need to poll their sensors all at once, changing exposure times, etc. for the entire sensor simultaneously. The human eye though is made up of many different cells which are continually exposed to light and can adjust their reporting of sensation individually. This means they don't need "multiple exposures" bec... |
what is the difference between Kaspersky and Norton and Avira, and why are they better than free antiviruses? | This is just my personal opinion. Norton and McAffe were great back in their day. They did a fantastic job for protecting a computer from getting infected. Now skip to today. These programs are now worse than the viruses. Mainly because they have jammed them full of junk outside of their original intended purpose. Spyw... |
where did the term 'uncle sam' (referring to the US) came from? | Not sure the actual origin but the early 1800s a man, Samuel Wilson, supplied beef to the army when it was in high demand.

Why do we have so many names for one organisation? | They have their own name and it is something like "الدولة الإسلامية في العراق والشام\u200e" obviously this doesn't really work well for anyone who doesn't speak Arabic so most people use a translation and since you can translate a phrase in many ways people end up with different translations and since these translation... |

If I tied a robust camera to a extremely long rope and blasted it into a black hole before pulling the rope back, what would I see on the camera? | Beyond the problems with doing this, that nothing is quite robust enough to survive even vague proximity to a blackhole and the problem of pulling it back out, we're not entirely sure, but we're pretty sure it is dull as hell.

What does the wavelength of light actually represent? | Simple answer for this is: energy. The energy of a photon directly corresponds to the energy of that photon. All photons move at the speed of light. If you gave a photon a kick to add energy, you can not increase it's speed. What happens is you increase it's frequency . We perceive different wavelengths of light in a c... |
why there are so many more men interested in programming? | Girls are brought up being told that computers are boys toys, so they're no interested. Simple as that.

How do the car key unlock button unlock a car and how does it open only that one specific car? | When you press the button, it sends out a radio signal with a unique identification number that your car recognizes and responds to.

What is net metering with solar power | Net metering allows those who generate their own electricity to feed their excess back into the electrical grid, and to get credit for their contribution so they are only billed for their "net" energy use. But if recent legislation removes or limits the need for them to give such credit then it can put bounds on your a... |
Why are humans scared of the dark? | I'm not really sure, but I think it's fear of the unknown, of having unreliable information. Especially when many predators have better senses. |

Why and how birds fly in an organized formation | For energy conservation. The birds in the rear get a certain amount of lift from the ones in front. They will change positions periodically. |
How does the placebo effect apply when its not for pain medication, but for a hallucinogenic drug? | The Placebo Effect is far far more wacky than you might think. It's not just good for mind over matter stuff like pain or intoxication. Not only can you get one placebo that's more effective than another, but it can help in completely insane ways. Two sugar pills work better than one, salt water injections are more eff... |
What's the deal with the "online mattress" industry? | They typically make them cheaper, and use no store front meaning they pay less people, so ultimately they're funneling all their extra expenditure into advertising The idea of the anti mattress store marketing is a viral yet subtle way of nudging little into buying something online, rather than go to a store then try a... |
