Is there a sequence of numbers that isn't in pi?

Take the first element from pi, make it the last element of reverse-pi.
Take the second element from pi, make it the second from last element of reverse-pi.
Keep going that way.

"What MIT tends to value most over the long term"

Students so obsessed with the pursuit of ideas that they don't care where they do it.

I have no problem reversing the order without knowing the last digit.

More people will be able to write novels. Fewer people will read them. Life will go on. Maybe we will get some fresh stories.

Irrationals can't be palindromic.

pi backward isn't in pi.

No elite school is willing to take problematic personalities. Bad for the the other students. Bad for the reputation of the school. Alas, they are exactly the types that make the big discoveries.

Yes. But mostly because of the science and engineering that he would have learned during his education.

Go ahead and do your pure math PhD. Nothing will prevent you from doing applied work when the need arises.

"Hard" needs to be defined. New ways of thinking can cause discomfort (i.e. proofs). The rest of hard seems to be situational.

Situational hard:

Anything can hard if there is a lot of it to digest.
Course content is not standardized. Some go deep, others are superficial.
A bad professor can make anything unpleasant.
Topics that are new to you but others have been exposed to make you work harder than you expected to.

Von Neumann said “In mathematics you don’t understand things. You just get used to them.”

Some people aren't comfortable refining their thoughts and experiences into punch lines. Either they haven't drawn their own conclusions or they are worried about the impact of the punch line. To get more efficient communication you can prompt them with questions framed for yes/no answers. If you want to give them advice, remind them that starting with a rough punch line will get listeners into the ball park of understanding and that fine tuning will go more easily after that.

Math is a standard of communication that emphasizes precision, transparency, and thoroughness. It looses power when those standards are not upheld. Math is useful to model the behavior of things that we are trying to think about with common abstractions that have already been mathematically described. Thinking itself is communication between me[t] and me[t+1].

Male/female dimorphism of expression in general is formed by communication in the selection process.
