I feel like mathematicians should be able to do a second doctorate level degree a few years after their first PhD, that must be in a adjacent field of their own

I feel like mathematicians should be able to do a second doctorate level degree a few years after their first PhD, that must be in a adjacent field of their own, but not the same.
- vanderZwan 1y agoI feel like most sciences should have this, it would accelerate science a lot via the cross-pollination of ideas and techniques. But I can imagine that drawing connections between different branches of maths would be especially powerful, yes
- karmakurtisaani 1y agoIt's possible! From somewhat famous mathematicians, at least Bela Bollobas has 2 PhDs: one in discrete geometry and one in functional analysis. Try doing that in the modern academic environment tho..
- wyan 1y agoThe purpose of a PhD is to certify that you're able to do independent research. Many researchers retrain (or just add a research interest) in adjacent fields during their postdocs or later. At that point it's just research.
- rando234789 1y agocheck out the idea of a habilitation: https://en.wikipedia.org/wiki/Habilitation https://en.wikipedia.org/wiki/Habilitation at least in germany, it is pretty much what you describe
- aleph_minus_one 1y agoBeside the habilitation example of rando234789 (https://news.ycombinator.com/item?id=44498702 https://news.ycombinator.com/item?id=44498702), in Russia (and Ukraine) there indeed exist two "doctorate levels": кандидат наук [Candidate of Sciences] and доктор наук [Doctor of Science].
