alt Hacker NewsI feel like the Wikipedia article does not explain the backstory well:
> Bourbaki was founded in response to the effects of the First World War which caused the death of a generation of French mathematicians; as a result, young university instructors were forced to use dated texts
Why would there not be textbooks after people died? Were they bringing the textbooks to the schools or something? Or were they saying that new textbooks weren't written because of the lack of French authors available? I hadn't thought that having textbooks maybe 15 years old would be a huge deal given the pace that math moves, but maybe that's only because the concepts for an undergraduate math course when I was in school were a lot further behind where the research is happening nowadays compared to back then.
Before the second WW, mathematics was moving at much faster paces than after WWII, when many theories became more or less settled and only their practical applications continued to develop at a fast pace.
The modern variants of some branches of mathematics like topology or the theory of tensors have appeared during the first WW (e.g. the book of Felix Hausdorff, "Grundzüge der Mengenlehre"). Especially topology had a great influence on almost all other branches of mathematics, prompting them to reformulate many things in more general frameworks.
Therefore, by the end of WWI, it was true that many older mathematics manuals were considered obsolete, so they felt the need to write new manuals, brought up-to-date.
