” The particular aspect of time that I’m interested in is the arrow of time: the fact that the past is different from the future. We remember the past but we don’t remember the future. There are irreversible processes. There are things that happen, like you turn an egg into an omelet, but you can’t turn an omelet into an egg. “


” The fact that you can remember yesterday but not tomorrow is because of entropy. The fact that you’re always born young and then you grow older, and not the other way around like Benjamin Button – it’s all because of entropy. So I think that entropy is underappreciated as something that has a crucial role in how we go through life. “


” Whenever you say you’re a physicist, there’s a certain fraction of people who immediately go, ‘Oh, I hated physics in high school.’ That’s because of the terrible influence of high school physics. Because of it, most people think physics is all about inclined planes and force-vector diagrams. “


” If time travel were possible, you still wouldn’t be able to change the past – it’s already happened! “


” The arrow of time doesn’t move forward forever. There’s a phase in the history of the universe where you go from low entropy to high entropy. But then, once you reach the locally maximum entropy you can get to, there’s no more arrow of time. “
