I just finished reading Neal Stephenson's book Anathem, and at the 1:20:00 mark where Lex starts talking about communicating with other races through math's theorems, it's crazy cause that's kind of a key feature within the novel and both ideas I've encountered for the first time in the last two weeks. It's crazy. The more that you do productively in terms of exploring ideas and fun conversations, the more coincidences you notice. And the rush of joy at noticing analogies to some past experience in a different field is one of the best and simplest pleasures around

I think that daily mental exercise you mention is a great practice. If I take at least 30-60 minutes to think clearly about some questions daily, I find myself being more deliberate throughout the day, and being more myself. Otherwise I go through my day almost like a robot, not really thinking about why I'm doing what I'm doing.

@@orangestapler8729 from what i've gathered, Julia is a high level high performance language. So you get syntax thats very readable (like python), but you don't have to compromise the performance (unlike python, which is rather slow). That being said, its more focused on scientific computing rather than, say, software engineering. The reason its a big deal is that most scientific computing applications (like optimization or numerical PDE) really benefit from being implemented with high level syntax, so the fact that now you can get that without having to put up with worst performance its great. If you want to know more i would recommend the article "Julia: a fresh approach to numerical computing" by Bezanson et al (2017)

I've got a question for you, Mr. Fridman. You know a lot, I know a lot, and we all know a lot. We like to learn new things and know (roughly) *when we do* . But a far more interesting and possibly more important question (for AI) is how could we ever determine when something is *forgotten* or when (in the passing years and decades) we forget something we once knew. Another important question is what exactly is meant by "how to think". Many people use that expression, but a bit too casually (in my estimation). What does it really mean? And does it mean different things in different contexts? For example, one may know "how to think" about unfamiliar mathematical problems, but not at all about something as simple/fundamental as what a healthy diet is and why. So, this really boils down to two questions: 1.) How might we ever determine when something is forgotten? 2.) What exactly is meant by this all-too-common phrase "how to think"?
@bradburdett44912 жыл бұрын
Stop thinking of forgetting as a negative thing. Forgetting is a filter of what's important. A 4 year old is mesmerized by a butterfly. A 70 year old appreciates it's beauty. The older you get the faster a year will go by. It seems this way because of The Filter of importance or The filter of Significance.

The techniques needed to solve them are elementary, solutions usually take one creative idea. The geniuses are those who not only can solve them (most math majors should be able to do maybe a half at least) but can do so in 1.5h per problem for both finding a solution and writing it up. I usually can't :).

And I doubt that every math major can solve half of them, even PhDs. But since you can solve a lot of them, can u maybe give me some advice on how to tackle those problems? How long should I try to solve before looking at solutions? You are definitely way smarter than normal to be able to solve those incredibly hard problems.

4:05 One of the best kind of structures for that experience, in my opinion, are those that rely on "tensegrity." They seem like they shouldn't work on an intuitive level because you're essentially holding up a table, monument, or even a building using, at least in a sense, rope, steel cables, or some other non-rigid materials as pillars, relying on tensile strength and particular weight distributions to create self-contained stability. Rather than treating gravity as the enemy of building upward, tensegrity ironically uses it to keep it the thing from falling down . It seems like the architectural version of pulling oneself up by the bootstraps.

And with today's tech, that means embedding the incentives into the digital interactions/transactions between individuals. The yet unrealized power of Blockchain is as transparent, verifiable, incentivisation technology. Am very optimistic that where we need to cooperate at scale - pandemics, environmental conservation, reducing economic inequality extremes etc we now have powerful sets of ideas we can bring to bear on this huge problems.
