Einstein and the Goldfish Bowl
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…
