How does the Michael Jackson hologram work? | This time, it looked more like it was just a cleverly hidden video screen. He didn't look very holographic to me. Now, Tupac at Coachella awhile back singing with Snoop was actually more impressive because it actually looked like he was onstage with real live artists. If they did, in fact, use a similar technique in th... |
Why are some replacement parts for electronics (i.e. laptops) nearly as expensive as the whole unit? | Bulk manufacturing pricing. They buy 10,000 screens from a suppler. That drives per unit costs down. You need to buy one, no incentive for them. |
- How is it possible to "add oxygen" to water and have it still be water? | It's called "snake oil". They're selling something useless and making outrageous health claims about it to convince rubes to buy it. It's a load of horse shit.What they're referring to is dissolving the oxygen in the water, the same way that carbonated drinks have CO2 dissolved in them. When you dissolve something, you... |
If all the cells in our body including neurons get replaced every seven years — how do we retain memories further in time? | Memories are stored in the pattern of connections between the nuerons, not in the physical matter of the body. Nuerons do not get replaced very often though. They typically last your whole life and recent evidence suggests that once they die, they do not regrow.

I vividly recall my confusion and initial disgust . Over the... |
Why does bath salts / minerals make bath water feel hotter than normal? | I don't have any source for this, but I'm guessing it might have something to do with bath salts removing dead skin. Think of water touching a cut where a fresh skin layer is revealed - it feels like it burns. Maybe the salts removing a "protective" layer of dead skin causes it to feel a little hotter. Not technically ... |
what did Nixon do to get everyone saying he was a bad President? | Watergate. The televised investigations made it appear that he behaved as a king, not as a president. In the aftermath, [during an interview with David Frost], he also said, "When the President does it, that means it is *not* illegal." While that might be true of a king, it is *not* true of a president of the United St... |
Why do you move your head back when your blow air out, and move your head forwards when you suck air in? | I am actually the complete opposite.. so I think you got the whole movement thing wrong. When you suck air in, your lung expand and the expansion of your lung/chest causes your neck so move you head back as a slight balancing.. not that you actually need to do it. When you blow, psychologically, you are trying to blow ... |
What is the difference between using shampoo and body wash? | Soap is soap. Shampoo can wash your body, or your car, just as well as it washes your hair.

Shampoos may have scents that are pleasing for hair, or additives... |

A kind of staleness to the air that astronauts lean to live wit... |
; Does fibromyalgia really have a cure? | [Disciplinary Actions against Michael Platt, M.D. ] He isn't a doctor anymore due to "negligence, incompetence, and inadequate record-keeping".

Why do we (men) enjoy seeing women's breasts? | I think it has to do with the thought of the breasts being seen as a comforting thought.

How does a radio station send metadata like song name to my car's radio? | Modulation became more efficient, which opened up space in the guard bands to transmit digital information on a sub carrier.

That code is the meta data.Yo... |

What's the point of dusting? Doesn't it just get the dust back into air circulation until it settles again? | Properly dusting involves using something that's going to capture the dust so it doesn't just go up in the air.

You see the road even ... |
why are humans the only mammals that continue to consume milk after infancy? | Most animals lose the ability to digest lactose when they become adults - their guts just stop making the enzyme needed to break it down. Some humans have a mutation which makes them keep producing the enzyme, so they can keep consuming milk throughout their lifetimes. I, however, do not have that mutation, so I am lac... |
I read that Heisenberg's Uncertainty Principle is often confused or conflated with the observer effect. If they aren't the same thing, then what is the uncertainty principle? | The uncertainty principle is a consequence wave mechanics. Take the probability density of a wave with a single well-defined frequency. That wave exists everywhere, so you can know the frequency but you have no idea of the location of a particle represented by that wavefunction. Any wave function that is localized is g... |
Why is dental work considered "cosmetic" when the health of your teeth effects the health of the rest of your body? | Not all dental work is cosmetic. But in many cases, Americans have dental work done to make their teeth look nicer regardless of whether its important to their health.I don't know the reason for this but vision coverage is considered cosmetic as well. It's bullshit, too, because without glasses I'd be unable to drive, ... |

Why do some identical twins start to look much less alike as they get older? | The difference in identical twins is largely because so much of how you look is actually determined by environment, but not in the way you might think.

Why do some animals/insects have a life span of a few days but others such as some turtles can live over 100 years? | The answer to why anything in nature is basically because it works and they keep having babies.

Why do we say every year before 2000 in the hundreds, and every year after in the thousands? | Because "18 hundred" is shorter than "1 thousand 8 hundred".

Why an object that is 10 billion light years across and 10 billion light years away is not the largest thing visible. | It's too dim, and it's not a single object.

If my company is worth $100M next year, then that 1% is worth $1M. When they ... |

Why Is It Legal/Okay For A Clearly Pregnant Woman To Go To A Bar/Club/Concert And Drink/Smoke Publicly? | It's legal because nobody has made a law saying it isn't yet, and that's how the law works.

Why do some books have spiked, uneven page edges opposite the binding, whereas others are flat? | This is called a deckled edge. It's a stylistic choice that makes the book seem older.

When patients are on life support for an indefinite amount of time, who is responsible for the bill? | correct me if wrong, but I believe any bills would be owed by JM individually, or her estate.

Why isn't space junk constantly coliding with the ISS and how do they protect themself from it? | Space is big. You just won't believe how vastly, hugely, mind- bogglingly big it is.

What is the point of image-based Captchas if there are already lots of bots that can solve them? Do ticket-reselling websites have some secret OCR/high performance photo recognition software that Google doesn't? | Captchas don't need to be perfect to be useful.

A speed bump can be as useful as a stop sign.Ticket sellers hire people to solve Captchas. They have softwa... |
I live in a town with a paper mill. How come it smells worse at night then during the day. | I’m not an expert on paper mills, but I know that sugar factories hire way mor employees and ramp up production at night because they can be louder, since there’s no traffic going by them during those hours.

Why are crayons considered children's toys, but nearly every other medium (ink, pencil, paint, etc.) is used in serious art? | Crayons don't lend themselves to fine details.

Closely related to crayons, however... |
