How can I as a common American citizen be reasonably assured that elections aren't rigged given non-audited, paper-trail-free electronic voting? | Let's say that the 2008 election was rigged.

When you get antibiotics, they kill certain types of bacteria and whatnot or they're *supposed to.* But because of random mutation, one bug in a zillion comes into being with the ability to resist the antibiotic, and it's left alive to reproduce. If it reproduces enough, then eventually, ... |
Why are taxpayers always liable for lawsuits against government instead of holding individuals accountable? | Because their jobs expose them to greater legal risks, and without some sort of gov't protection, no one would do them.

This usually means taking a sample of someb... |
how is it physically possible for a mantis shrimp to punch so fast? | The punch of a Mantis shrimp really is incredible.

Why do things spinning at a certain speed, appear to slow down and spin the other direction after a few seconds? | Remember that you don't experience the real world.

I'm about debate my data cap with my cable co. after they called regarding my fcc complaint. Can you explain congestion and if it's a valid excuse for them? | Depends on where you live, but it usually isn't. Congestion is when lots of people are trying to push 1's and 0's through a network, and the network can't always deal with all of it at the same time, so some 1's and 0's have to wait a bit. If your ISP is justifying a data cap with the qualification that the vast majori... |

How and why did humans develop speech and language? | We don't know. There are lots of conjectures, but most of them are, to put it in ELI5 terms, ridiculous.

Why are dreams that occur after hitting the snooze button falling back asleep after an alarm so much more frequent and crazy than ones during the rest of my sleep? | Two possible explanations.

If you overhear a conversation and an opinion that you think is stupid, telling th... |

Fluid and electrolyte balance/imbalance in the human body. | The human body requires a constant amount of fluid at specific concentrations to function efficiently. The outside environment does not offer this. Thus, the body has various mechanisms it uses to keep the internal environment as constant as possible. For instance, when you drink water, the body must accommodate this e... |
Why does the sound of hot water hitting a tile sound different from the sound cold water makes hitting the same tile? | The reason it sounds different is that the molecules in hot water are moving at a much faster rate and are much farther apart than in cold water. The faster the molecules are moving, the lighter and higher pitched it will sound hitting the floor. On the opposite end, the slower molecules are moving and the closer they ... |
If our bodies get tired when they're cold, then why does being under a warm blanket make us so sleepy? | 2 different things are going on here. 1. You're tired when it's cold because your body has to use a lot of energy to stay warm. Use up energy - > get tired 2. The reason people sleep with thick blankets is kind of weird. The weight of the blanket on your skin triggers the deep pressure receptors in your skin, which is ... |
Can someone explain Reaganomics? | Also referred to as Trickle-down Economics. The big idea is that you reduce taxes on wealthy business owners, and they in turn spend more money. That money trickles down through the economy, where it eventually reaches the working class. Critics of Reaganomics, including myself, argue that the tax break dollars will pr... |
MLB Trade Deadline is July 31st. Why and how are trades made until August 31st? What is this difference between a waiver and a non-waiver trade? | The trade deadline of July 31 is for teams to trade directly with each other without going through waivers. Waivers basically means that the player is offered to all the teams first so the player can be claimed and the other teams takes his services and contract.

Why do we tend to hear familiar sounds within white noise or background noise? | In the presence of "blank" stimuli, E.G. white noise or diffuse monocolor light, our brains begin to amplify the tiny differences that exist, and then string the amplified differences together to try and make "sense" of what's going on. You are just hallucinating since your brain is misinterpreting what's going on. |
Why do guests wake up before the host at a sleepover? | It's much harder to sleep somewhere unfamiliar. Additionally, the host will usually be the last one to sleep since they need to make sure all their guests are set up with sleeping arrangements, so they may take longer to wake up. |
Why Pineapple stings/burns your tounge when eating too much? | The simple answer is that it's eating you while you're eating it. There are enzymes present in pineapple that break down proteins, and since the inside of your mouth is made of protein, it breaks it down. |
How do insects, that look exactly like leaves, adapt to camouflage that way? How can their DNA know what their environment looks like? | It doesn't, it's just that the DNA that gets it wrong tends to die. It's not DNA that makes the decision if a certain trait is good or bad. Rather, the environment makes that decision, one generation at a time, by killing the losers. Their ancestors happened to end up looking a lot like local leaves, and it helped so m... |
Why didn't wildfires burn down entire forests in the US when we now have a lot of trouble dealing with them despite having better equipment? | Wildfires used to be more common, but not nearly as intense. Forests were not as dense, and underbrush was not as thick . Now, once we got to a point where humans started stopping forest fires as soon as they started, the forest began to see fewer fires which would lead to a buildup of undergrowth, and increased tree d... |
