We sat down in Jeremy Burman's (@BurmanPhD on Twitter) book-filled office to talk about... well, a lot of things. He is a historian of science, currently investigating Jean Piaget's lost work on child development, among many other topics. He shares with us his personal history, which starts in the "dot-com" era, hoping to become a multimillionaire. Why did he switch from dreaming of market dominance to writing about how concepts change over time?
