00:00What is time? That's something that many people think they know the answer to. They have written
00:13books about it. I'm not convinced by any of those opinions, and I do wonder about it.
00:22The Earth's rotation is affected by many things. The tides represent the oceans attempting
00:29to follow the moon, and when they hit the seashore, it actually slows down the Earth
00:35over geological time. We can infer that in the dinosaur days, the day was only about
00:40twenty hours long. Now we're twenty-four hours long. In the future, we're going to be longer
00:45still. There's no such thing as a perfect clock. Every clock has its own irregularities,
00:53but we don't have to be victim to those irregularities. We can correct for them, and by combining
00:59clocks we can get better time than any one clock, and more robust time. I've never liked
01:08to carry watches. I don't really want to confine my concept of time to the measurement. I'm
01:16too obsessed with the measurement. I can lose track of the big idea, and also lose my own
01:21innate sense of time. One of the things that impresses me most about this is the finiteness
01:29of time. Is time just a coordinate that we use to do things that maybe time doesn't even
01:37exist? Maybe time starts and then we'll have an end of time? What does it mean? How is
01:44time related to infinity? I don't have answers for those. I do wonder about them.
