Joel Ben Izzy and No Square is Negative


Joel Ben Izzy is still as great as he ever was. I guess one never gets tired of his stories even though they’re the same ones he told in 1990 (and probably long before then also). I need to find an excuse to get his book now, but I just spent $170 on textbooks for next quarter on Monday, so I need to stop spending money.

I figured out that I can solve a lot of analysis problems using “No Square is Negative” (which is incidentally the title of section 2.1 in Mathematical Olympiad Challenges) instead of “properties of orthonormal systems.” Now I feel clever. I’ll probably feel less clever if the grader writes that my proofs are nonsense, but until then I would prefer to remain clever. Codimension problems are still annoying though because I can’t use “No Square is Negative.”

About Simon

Hi. I'm Simon Rubinstein-Salzedo. I'm a mathematics postdoc at Dartmouth College. I'm also a musician; I play piano and cello, and I also sometimes compose music and study musicology. I also like to play chess and write calligraphy. This blog is a catalogue of some of my thoughts. I write them down so that I understand them better. But sometimes other people find them interesting as well, so I happily share them with my small corner of the world.

    Cleverness being relative, etc.
    You shall remain clever as long as you believe it to be so, methinks… But then, no one ever accused me of thinking particularly hard, especially at one-twenty in the morning while attempting to write english projects… Either way- remain clever for, it is all in your head, as negative as that may or may not sound…
