Funny story - the scientists were doing a completely unrelated test where they earmarked mice with small holes. After a while they couldn't tell the earmarked mice apart from their non-earmarked counterparts, as the holes had regenerate... |
Why do catchers in baseball give the pitchers signals? | The pitcher and the catcher usually work out in advance a general strategy, so in most cases the catcher is simply *confirming* what kind of throw to expect. The pitcher will sometimes shake a signal off, which tells the catcher "no, try something else." The pitcher makes the ultimate call, but it's up to the catcher t... |
Climbing Mt. Everest - don't we have the technology to make climbing relatively safe, at least for rescue and cleanup crews? | No. Pressurized means that the suit is sealed, which means it is a full body suit, thus bulky. Winter clothes and an oxygen bottle do the job very well. Winter clothes keep you warm, while oxygen bottles keep you concious near the peak. Frankly, the real issue isn't the gear. The problem is that tourists with no proper... |
Why do we get goosebumps when we get excited. | I wasn't aware that people got goosebumps when they are excited. I've never experienced this, but now I want to. |
Why is it considered useless to duct tape windows during a hurricane. Seems very counter intuitive to me. | Hurricanes can toss a 2x4 through 6" of concrete. Even plywood isn't considered good enough to protect windows from having debris thrown through them. Unless you have metal hurricane shutters attached to the structural frame of the house, your windows will likely take damage. Once one window is gone, your house works l... |
the mathematics behind the notation to understand large numbers. | I'm pretty sure there's not such a thing as a "standard notation for huge numbers" or anything, each of those numbers you listed were first defined in order to solve an equation or proof in a particular field of mathematics, so when you read about them the notation you see will be specific to the problem where the numb... |
Why do Rockets go so slow after takeoff if they are so powerful? | They are just speeding up — just like a race car leaving the starting line. In a few seconds they are going very fast indeed. Edit: [here is a graph] of a moon rocket's speed over time. Within 20 seconds it's going well over 200 meters per second, that is, over 500 mph. |
Why do black objects absorb more heat than other colors? | The reason *why* it is black, is because it is absorbing much of the light striking it among all wavelengths, rather than reflecting off some or all wavelengths and causing you to see white/colors. That absorbed light turns to heat. Interiors of cars are further warmed by the fact that windows are transparent to visibl... |
