I had the pleasure earlier this month of giving a plenary lecture at a meeting of the American Astronomical Society. Unfortunately, as far as I know they don’t record the lectures on video. So here, at least, are the slides … Continue reading
Finally back from Scotland, where I gave a series of five talks for the Gifford Lectures in Glasgow. The final four, at least, were recorded, and should go up on the web at some point, but I’m not sure when. … Continue reading
A temporary break from book-related blogging to bring you this delightful video from A Capella Science, in which Tim Blais sings about entropy while apparently violating one of my favorite laws of physics. I don’t even want to think about … Continue reading
Entropy increases. Closed systems become increasingly disordered over time. So says the Second Law of Thermodynamics, one of my favorite notions in all of physics. At least, entropy usually increases. If we define entropy by first defining “macrostates” — collections of … Continue reading
The idea that time isn’t “real” is an ancient one — if we’re allowed to refer to things as “ancient” under the supposition that time isn’t real. You will recall the humorous debate we had at our Setting Time Aright … Continue reading
I still haven’t seen Interstellar yet, but here’s a great interview with Kip Thorne about the movie-making process and what he thinks of the final product. (For a very different view, see Phil Plait [update: now partly recanted].) One of … Continue reading
There’s no question that quantum fluctuations play a crucial role in modern cosmology, as the recent BICEP2 observations have reminded us. According to inflation, all of the structures we see in the universe, from galaxies up to superclusters and beyond, … Continue reading
“Teleology” is a naughty word in certain circles — largely the circles that I often move in myself, namely physicists or other scientists who know what the word “teleology” means. To wit, it’s the concept of “being directed toward a … Continue reading
I mentioned some time back the Closer to Truth series, in which Robert Lawrence Kuhn chats with scientists, philosophers, and theologians about the Big Questions. Apparently some excerpts are now appearing on YouTube — here I am talking about whether … Continue reading
