Growing up, I was always hearing people asking others if they had worms if they had a healthy appetite. Is that an old wive's tale or something? If not, why is the person eating more? To replace nutrients taken by the worms from the intestines?

Einstein arrived at some of his ideas by picturing himself riding on a beam of light. What if that beam were slower due to passing through a medium? Would that affect simultaneity across the boundary of the medium? Wouldn't distant stars be seen in the more distant past? We know that time runs slower on the outside of a rotating disk than it does on the inside. Does time run at a slightly different rate underwater? This has no effect on relativity - in fact, I am trying to live within the confines of relativity.

Well, i don't even know if there's evidence that life started on earth but there probably isn't any saying otherwise.

If every person in the boat is going to apply the same amount of force when they row no matter what the others in the boat are doing, why does it matter if they're all rowing together? I understand that all rowing together results in a stronger individual burst, but why is one strong burst any stronger than multiple weak bursts when the sum is the same?

I understand theoretically that if everyone's moving at once, the resistance to individual rowers appears lower - but why is that, if they're still applying the same amount of force?

Explain how the PCM works. Why is it enough to receive a transmission of at least 56kbps to listen to music over the Internet? Does this transmission rate violate Nyquist theorem? Justify the answer. the bandwidth of a public telephone line is about 4KHz
