Can anyone recommend readings on von Neumann that highlight his non-mathematical achievements? Obviously he was primarily a physicist and mathematician, but for a non-mathematician, the long list of academic publications is hard to interpret and appreciate. For example, more in the vein of these: - Reportedly, von Neumann possessed an eidetic memory, and so was able to recall complete novels and pages of the phone di…

> Reportedly, von Neumann possessed an eidetic memory, and so was able to recall complete novels and pages of the phone directory on command. This enabled him to accumulate an almost encyclopedic knowledge of what ever he read If he was able to recall ~entire pages of the phone directory on command, I wonder if he could also recall (near) verbatim text of all the novels he had ever read, to what degree he could do th…

Supposedly, yes-- during his final stay in the hospital, his brother read to him from a book they'd enjoyed during their childhood, Dickens' A Tale of Two Cities. When his brother had to turn the page, John would continue the narration from memory while his brother found his place on the subsequent page.

Given that he could be occasionally absent minded, I suspect that it had to be something that piqued his interest, but his sense of what was interesting was extremely broad.

He did in fact speculate on the workings of the brain in The Computer and the Brain, which is based on a lecture series he had planned out but did not deliver. It was more in the context of automata theory, but as someone with an interest in AI, automata, and neuroscience, it was frankly rather dank[0]. A lot of the pioneering work was, and is enjoyable in part because it's original and speculative, so you don't have to master the literature to make sense of it, you can just pick a paper and go. I'd recommend reading Pitts and McCullogh, plus also Lettvin, but others might have some equally lit[1] recommendations.

0. In the contemporary sense, c.f. "cool", "dope", or "excellent"; not dank like a root cellar.

I think moderators should mark articles behind paywalls as such, I already don't click on wapo or nytimes links but you never can tell with medium. I'm retired on a fixed income and I can't justify in my budget subscribing to these places. It makes me sad when I can't read an article that might otherwise fascinate me. One solution would be to never click on medium links, but then I'd miss the ones that are free.

Medium really botched the paywall approach and I couldn't possibly agree with you more. It is so inconsistently applied and quite honestly I can't justify spending 5 dollars a month on a "publisher" whose content is so variable. Some Medium articles are really good, others are baseless clickbait, it's hard to tell until you read the article and already sunk the time and the money.

"Von Neumann would carry on a conversation with my 3-year-old son, and the two of them would talk as equals, and I sometimes wondered if he used the same principle when he talked to the rest of us." - Edward Teller See [0] for a demonstration. I watched a documentary from the 80ies a long time ago. A mathematician (can't remember his name) who worked with von Neumann in Los Alamanos was interviewed. He described von…

Here is that exact documentary you were thinking of [0]. It's really a fantastic documentary on the incredible feats of von Neumann and worth a watch by everyone here. That person you quoted was Edward Teller and the interview can be found at 54:58 [1]. I read somewhere that the young boy asking von Neumann a question at 6:13 [2] is actually Bill Clinton. Can anyone verify this? [0] https://youtu.be/Y2jiQXI6nrE [1] h…

Ha, that is indeed the exact documentary I was talking about, thanks!

I have no idea about the state of modern mathematics but I wouldn't have guessed that the idea of a lone mathematician has passed. What are the big projects in mathematics?

It would take people like us (anyone who doesn't already know the big projects in math are) years of study to resolve that list in to anything more than names. However if you're looking for a modern math celebrity I'd volunteer Terrence Tao. Although only a mathematician could understand what he's working on it's clear from how he's talked about that in eighty years people will be saying, "I wonder if there will be a…

I've taken a medication that occasionally makes me feel stupid. For a day I might be unable to continue reading a book without re-reading each sentence a few times. I might not be able to talk to people about a complicated or technical subject without stumbling over my words. I will find it difficult to think in the abstract terms, and when I listen to others who talk about abstract values and concepts I have to cont…

The sad reality is that cognitive decline over age is more likely than not. I have prebuilt a set of habits that I hope will serve me for when I need to rely on them to get me through the day.

I hope that regular exercise of my body and mind can minimize this.

> Hungary had a great education system at the time. I seriously doubt you could back this. You are generalizing from a single school. Might as well argue that socialist Hungary had a great education system because of Fazekas. Neither are true. I happen to have a maths teacher degree from a Hungarian university and we studied Hungarian education history and I learned much more about education systems later on my own (…

While having a much smaller population (10M), Hungary places 4th in worldwide medal rankings on the International Mathematics Olympiad [1] behind China (1.5B), USA (300M) and Russia (150M) [1]: https://www.imo-official.org/results_country.aspx?column=awa...

Well, that's historical. In 2019 it was 1. China 1. USA 3. S. Korea (51M) 4. N. Korea (25M). And Hungary lost to Serbia (7M).

I have always wondered how close von Neumann was to the maximum human potential. Does he sit close the outer edge of possible human potential, or can greater geniuses be created? Is there anyone alive who even comes close to Johnny?

Imagine a von Neumann who didn't drink and kept himself in shape.

So he has what's called Photographic Memory ?

Not really. From the wikipedia page on eidetic memory [1]: ``` Although the terms eidetic memory and photographic memory are popularly used interchangeably,[1] they are also distinguished, with eidetic memory referring to the ability to view memories like photographs for a few minutes,[3] and photographic memory referring to the ability to recall pages of text or numbers, or similar, in great detail.[4][5] When the c…

I've always wondered about that, because a few savants like Kim Peek are/were able to recall everything they read.

"He could speed through a book in about an hour and remember almost everything he had read, memorizing vast amounts of information in subjects ranging from history and literature, geography and numbers to sports, music and dates. Peek read by scanning the left page with his left eye, then the right page with his right eye. According to an article in The Times newspaper, he could accurately recall the contents of at least 12,000 books."

There is no reason to think we are no longer producing people with colossal intellect. They are probably now collaborators on a large project, since that is what math and science have become. Plus we haven’t had enough time to make myths about the recent times. Of course the 20th century was incredible for physics, but we don’t know yet what will make the recent years special. We may, for example, in 80 years wonder…

It's also possible that the greatest minds of our time aren't engaged in furthering our understanding of the universe, but instead devising more efficient ways of displaying internet advertising or faster stock trading algorithms.

I've always felt that this is USDA Prime bullshit.

Einstein wasn't wasted away his years at the patent office.

Also you could say that the greatest minds of the 20th century all engaged in coming up with bigger and bigger explosions for the military.

And so on.

I have no idea about the state of modern mathematics but I wouldn't have guessed that the idea of a lone mathematician has passed. What are the big projects in mathematics?

I'm not sure if it's necessarily big projects but the proving difficult theorems today has often involved the construction of huge "machinery", whole branch of math, that then get applied to simple-to-state-but-difficult-to-prove theorems, the example being Wiles using modular form theories to prove Fermet's last theorem.

And this situation comes because all (or the great majority) of the easy theorems have been proved for most established branches of math.

This also means great discoveries are coming at a later age for mathematicians, as simply getting up to speed in complex fields takes years.

All of this implies it would be hard to have another Von Neumann today.
