mathgenius··on How to become a bad theoretical physicist (2017)
" The bad theoretical physicist, in anticipation, names his own equations and effects, and even his entire theories, after himself right away. "

I never heard of anyone doing this, is there an example of this?

The real trick is to not name some important discovery, which then leads others to name it after you. Or, to use a hopelessly unwieldy terminology for the discovery with hopefully the same outcome. If the discoverer comes up with a good name for their discovery then this significantly reduces any chance that the effect will be named after them.

mathgenius··on Mathematicians prove symmetry of phase transitions at critical moments
Yes, these when these models become critical (eg. where the distinction between liquid & gas goes away [1]) they form clouds of condensation at all scale sizes, so it is like a fractal.

This sounds a bit like "Ad buddy", from a Netflix sci-fi series called 'Maniac':

"If you’re broke, you can sell yourself to an “Ad Buddy,” whereby your bills get paid in exchange for a person accompanying you everywhere and spouting advertisements, like a human pop-up you can’t close."

This is just not accurate.

"I find it absolutely insane that interactive proof assistants are now at the level that within a very reasonable time span they can formally verify difficult original research." Peter Scholze [1].

This is gold. I'm starting to realize (20 years in) that who you work with, and for, makes the difference. I really need to make this a priority for my next gig.

But turtles do not use coordinates, if anything they use (relative) polar coordinates ... Oh, maybe you first coordinatize the house drawing and then make turtle commands from that? It seems that turtle programs don't need any mathematical priming....
mathgenius··on ‘Positive deviants’: Why rebellious workers spark great ideas
I consider myself one of the rebellious workers, and fully admit most of my ideas should be thrown out the window. I spend a lot of my time ruthlessly invalidating those ideas. The most difficult are the ones that cannot be immediately disposed of, they can sometimes linger on for years.

The fearful leader types, on the other hand, will leap at the first idea they have and then "pile on", in a grim white-fisted way, until death do they part from their idea. This leads to fucking chaos, and is generally why these types do not like new ideas but prefer incremental approaches. IMO.

A big revelation happened for me in 2006, when I was privileged to participate in a Pypy sprint. The Pypy codebase is by far the most creative and awe-inspiring codebase I've ever seen. At the time, Armin Rigo and his close collaborator (Samuel?) were spit-balling ideas for implementing a particular idea. These guys stood at the whiteboard and went through one spectacular genius idea, one after another, until they found something they really liked. I would have stopped at the first genius idea, but not these guys. That was a big lesson for me in programming and definitely lifted my game.

mathgenius··on The Modern Mathematics of Deep Learning
After skimming through the paper it's clear that the title should be read as "The Modern (Mathematics of Deep Learning)" and not my original parse which was "The (Modern Mathematics) of Deep Learning." Very different things.

mathgenius··on Collusion rings threaten the integrity of computer science research
> the software industry

How many industries have you worked in? This is fairly common in many walks of life. As I get older I'm getting better at identifying the lunatics in charge. Often they are nice people, but also cause massive amounts of chaos, because they have no clue what is going on. No wonder they feel the need to exert micro-control.

Anyway, thanks for the rant. Always interesting to look at the bottom of the barrel for the HN rejects :-)

mathgenius··on I still like C and strongly dislike C++
How often have I heard of people running into C++ compiler bugs. Oh the horror. This is what originally bit me in the 90s, and I never went back to C++ again.
mathgenius··on The problem with ‘follow your dream’
> working on black holes or cosmology

99% of theoretical physics papers consist of torturous incremental research that no one gives a shit about, not even the authors. (I might be exaggerating slightly, but not much.)

mathgenius··on The problem with ‘follow your dream’
There are deep connections between dynamic programming (Bellman's equation) and the Hamilton-Jacobi wave equation...
mathgenius··on Ask HN: What are some tools / libraries you built yourself?
Thanks for the explanation. I often forget how good we have it on HN, until I spend some time over on twitter or reddit.
mathgenius··on Ask HN: What are some tools / libraries you built yourself?
That sounds like fun (except for the java part!). How did it go?
mathgenius··on Ask HN: What are some tools / libraries you built yourself?
I don't think you are shadowbanned, i can see your comment. You're welcome on HN anytime you want to come back. Btw., when i first came accross HN, some 10 years ago, i had this same fear of being shadowbanned. Heh.
mathgenius··on Ask HN: What are some tools / libraries you built yourself?

mathgenius··on Kindergarden Quantum Mechanics Graduates
> We're near a visual turning point.

When Newton wrote his Principia, he had to turn all of his algebraic calculations into geometric manipulations, so that people would actually believe his results. Now we are faced with the reverse: graphical calculi manipulations are having to be rewritten into algebraic notation in order for papers to be published [1].

mathgenius··on Monolith First (2015)
I take this same philosophy at all levels of my code. It's like the big bang: start out with a dense hot lump of code and as it grows and cools off things break apart into subunits and become more organized, documented, standalone, etc.
mathgenius··on Microsoft’s big win in quantum computing was an ‘error’ after all
> they haven’t a clue

Excuse me? They have plenty of "clues". Have a look at this for some recent work from the google group:

https://scirate.com/arxiv/2102.06132

Will it lead to quantum computers in the future remains to be seen, but "haven't a clue" is just nonsense.
