Einstein and the Goldfish Bowl

Logic
Einstein and the Goldfish Bowl By Ellen Hetland Fenwick I absorbed Einstein physics very well. I understood the changes. He made significant use of Riemann geometry, in which there are an infinite number of parallel lines through a given point. The geometry is part of the mother’s milk of mathematicians. The equations were relatively simple. I was comfortable and a believer. There's Always a String Attached When string theory came along, I pondered for a while about whether it was worth the time to study it. Mostly it was theory with no data to verify its conjectures. And, of course, there were several string theories to choose from. I said, “Let’s wait until they agree and have some evidence to support the theory”. Meanwhile people adept at Physics are, I…

Paradoxes: The Box Problem: Remember the puzzle I posted a short time ago? I state it again... The boxes below contain the BOX numbers of five boxes: BOX 0 contains all BOX numbers that do not contain their own BOX numbers. Here are two questions: Should 0 be in Box 0? Should 0 not be in Box 0? The answers to the questions are as follows: If 0 is in Box 0, it should not be. If 0 is not in Box 0, it should be. This is an example of paradoxes. Here are some others. Paradoxes: The Barber Problem The barber shaves all those who do not shave themselves. Who shaves the barber? Answer: if he shaves himself he should not; if he does not shave himself he should.…
