Today, we interviewed Paul Halpern, science author and professor of physics at the University of the Sciences in Philadelphia, to talk about his new book The Quantum Labyrinth. This story starts right here in Princeton in 1939, detailing the meld of minds between famed physicists Richard Feynman and John Wheeler. The two scientists worked together on pioneering quantum electrodynamics; both participated in the Manhattan Project in very different ways; and later collaborated on pushing modern physics toward where we are today. Listen to hear the full story on quantum fluctuations, wormholes, quantum computers, black holes, and how one electron might travel back and forth in time and make up the whole universe (or not).
Also recently in science:
- The “brazil nut effect” where big objects tend to rise to the surface above smaller ones seems to be helpful in preventing river erosion.
- Humans learn to see certain colors only when their language gives them the means to do so: for example, very few cultures could see blue until the modern era.
- The Moon’s origin story just got more complicated, as scientists have new evidence that the early magma-moon was too liquidy for the mineral on its surface to float to the top.
