I am dim today. Is this Tao getting rejected for some interview for something?

It's his "general exam" to start his PhD at Princeton

It's just faculty ensuring he has enough general knowledge of mathematics

At this point in time he would've been a teenager

I did state though that all second derivatives of u would have L^p norms bounded by that of the Laplacian. Kleinermann asked me for an elementary explanation of this, but I couldn't think of one. I haven't the foggiest idea of what an "elementary explanation" of anything during a math graduate degree committee assessment would even sound like.

Thought this Oppenheimer anecdote may amuse the HN contingent.

"Oppenheimer obtained his Doctor of Philosophy degree in March 1927 at age 23, supervised by Max Born.[28][29] After the oral exam, James Franck, the professor administering, reportedly said, "I'm glad that's over. He was on the point of questioning me."[30] "

Franck had won the Nobel two years earlier.

"Elementary" is a somewhat subjective term that roughly means "from first principles", i.e. not relying on a bunch of advanced theorems and concepts. It doesn't necessarily mean the explanation is simple or concise.

These go by different names at different schools, but a grad student has to pass an oral exam, roughly at the end of their coursework and beginning of their dissertation phase. Sometimes called "orals," "comprehensive exams," etc.

By tradition, they can ask you anything. But in practice, they're not out to kill you. I went to a second tier university, and it was generally believed that the questions at a top school tended to be harder. I have no recollection of mine.

At this time, you also typically present a proposal for your thesis project. Passage of these hurdles makes you a "candidate," i.e., a candidate for a PhD upon defense of your thesis.

I keep making this mistake. I almost asked "why philosophy, didn't he study physics?"

That does make me wonder: why DOES the qualification/position/status name mention only philosophy?

My first distracted thought upon reading this title on HN: cool, Terry Tao is finally getting his own army! Jokes aside, Tao also has a nice write-up in AMS Notices on this experience and how it influenced his career: https://www.ams.org/notices/202007/rnoti-p1007.pdf

I misread it as Tery Tao's genitals. I had a very different experience.
