Quantum Bayesianism Explained by Its Founder

QUANTA MAGAZINE: You’ve said, “I knew I had to become a physicist, not for the love of physics, but for the distrust of it.”CHRISTOPHER FUCHS: I was a big science fiction fan when I was a kid. On the other side of the fence was Albert Einstein, who said quantum mechanics is not complete. When he described probabilities in quantum mechanics, he seemed to interpret them as statements of incomplete knowledge, subjective states. He played up the similarities between quantum mechanics and relativity, and he couldn’t understand why Einstein wouldn’t accept quantum theory. Treating quantum mechanics as a single-user theory resolves a lot of the paradoxes, like spooky action at a distance.

N. K. Jemisin’s Dream Worlds

Several years ago, N. K. Jemisin, the fantasy and science-fiction author, had a dream that shook her. If the woman in her dream inhabited that planet, she wondered, then what would her civilization look like? “I’m, like, O.K., why isn’t she working to stabilize this powerful, wealthy part of society?” Jemisin told me. Jemisin wrote it in the second person, the voice belonging to a narrator who is not revealed until a later book. “I couldn’t get too close to her—she was angry with me in the dream, she’s not going to talk to me.

Discovery of oldest bow and arrow technology in Eurasia

More extreme environments, such as the tropical rainforests of Asia, have been largely overlooked, despite their deep history of human occupation. The question as to exactly how humans obtained rainforest resources—including fast-moving food sources like monkeys and squirrels—remains unresolved. At ~48,000 years old, these tools are earlier than the first similar technology found in Europe. Clear evidence for use on the preserved bone arrowheads shows that they were likely used for hunting difficult-to-catch rainforest prey. There, symbolic and technological innovations have been seen as key survival mechanisms equipping expanding populations to face cold northern climates.
