At The Edge
Sabbagh, the author of a book on the Riemann Hypothesis, tells us that he used to believe experts, but now he figures his guess is as good as theirs. Interesting essays on the scientific front include one by Ledoux, who explains that memory is not stored in the brain, one by Deheane on a theory of the brain being developed by Friston et al, and another by Steinhardt on taking quantum cosmology seriously. The token women include Janna Levin, who questions the assumption that the universe is infinite. Meanwhile, the journalist De Pretis discovers social processes in science.
