So it's true there were tremendous breakthroughs in the last century. But if you know what the universe is made of, that's going to tell you how, to some extent how it evolves. And if you know how it evolves that gives you constraints on what it's made of. So it's not like there's one field of physics and you can do it in complete isolation from another one. I mean, part of what makes the field rich and enjoyable for me is that you can ask questions not just about elementary particles, but also about cosmology. And when you begin to think about ideas about the whole global nature of space time, you can't help but

determines how language in a particular country evolves. Why is French for example so different from German? You know, there's no simple measure of how different languages are from one another. In fact, if you look at the language is structurally the way a linguist to look at the French is different from the other romance languages in a variety of ways, which are, which make it more similar to German and other Germanic languages. There are a number of features of French which are sort of Germanic in character.
