Is the universe infinite or just really big? With this question, cosmologist Janna Levin announces the central theme of this book, which established her as one of the most direct, unorthodox, and creative voices in contemporary science. As Levin sets out to determine how big "really big" may be, she offers a rare intimate look at the daily life of an innovative physicist, complete with jet lag and the tensions between personal relationships and the extreme demands of scientific exploration. Nimbly explaining geometry, topology, chaos, and string theory, Levin shows how the pattern of hot and cold spots left over from the big bang may one day reveal the size of the cosmos. How the Universe Got Its Spots: Diary of a Finite Time in a Finite Space (Princeton UP, 2023) is a thrilling story of cosmology by one of its leading thinkers.

Tom Mustill, "How to Speak Whale: A Voyage into the Future of Animal Communication" (Grand Central Publishing, 2022)

What if animals and humans could speak to one another? Tom Mustill—the nature documentarian who went viral when a thirty‐ton humpback whale breached onto his kayak—asks this question in his thrilling investigation into whale science and animal communication.

“When a whale is in the water, it is like an iceberg: you only see a fraction of it and have no conception of its size.”

On September 12, 2015, Tom Mustill was paddling in a two-person kayak with a friend just off the coast of California. It was cold, but idyllic—until a humpback whale breached, landing on top of them, releasing the energy equivalent of forty hand grenades. He was certain he was about to die, but they both survived, miraculously unscathed. In the interviews that followed the incident, Mustill was left with one question: What could this astonishing encounter teach us?

Drawing from his experience as a naturalist and wildlife filmmaker, Mustill started investigating human–whale interactions around the world when he met two tech entrepreneurs who wanted to use artificial intelligence (AI)—originally designed to translate human languages—to discover patterns in the conversations of animals and decode them. As he embarked on a journey into animal eavesdropping technologies, where big data meets big beasts, Mustill discovered that there is a revolution taking place in biology, as the technologies developed to explore our own languages are turned to nature.

From seventeenth-century Dutch inventors, to the whaling industry of the nineteenth century, to the cutting edge of Silicon Valley, How to Speak Whale: A Voyage into the Future of Animal Communication (Grand Central Publishing, 2022) examines how scientists and start-ups around the world are decoding animal communications. Whales, with their giant mammalian brains, virtuoso voices, and long, highly social lives, offer one of the most realistic opportunities for this to happen. But what would the consequences of such human animal interaction be?

Here are some recordings of whale songs:

The Role of Luck in Science: A Discussion with Nicolas Christin

Listen to this interview of Nicolas Christin, Professor at Carnegie Mellon University, jointly appointed in the School of Computer Science and in the department of Engineering and Public Policy. We talk about the luck it takes to succeed in research, and of course too about the initiative shown by successful researchers to seize that luck.

Nicolas Christin : "You will get a pretty good understanding of where some research idea has come from if you read the Introduction of the paper very carefully. Because the Introduction will typically start with either a sort of case study, 'Alright, so, x does y and this is what happened to them, and so, yeah, we need to fix that problem' or the Introduction will tell you how the paper inscribes itself in a larger body of work but without going through all the related work, as in, 'Yeah, we are different from A, B, and C in this and that way' but instead like 'Yeah, this is what the state-of-the-art is and this is what we are bringing to the table.' And as you read this, you can back-track it all and then see what the initial spark was, what the key motivation for that whole line of research was. Because in some cases, when you do this careful reading, say, ten years after the fact, you know, when you return to the seminal papers in your field, there you may realize or you may find out that the initial idea came from a case study or from a problem that actually was not a problem at all, because really the thing just became famous because it was applied to a different context. And that is, of course, completely fine. In fact, it tells you something about the serendipity or the randomness of what sticks and what doesn't."
