Curious physicist and programmer

@davepl1968 Doesn’t seem right unless the bit can take ten values.

[Kristofer Björnson @KristoferBj]

@martinmbauer There is something transformational in realizing that it all follows from three actions you can perform with sticks and rope in sand, and two assumptions about the relations between the lines drawn.

@davidbessis An ideal heat engine running between there would have a thermal efficiency of about 34%, Not too bad given that it wouldn’t consume any additional fuel.

[Kristofer Björnson @KristoferBj]

@notch I highly recommend the book visualizing quaternions for this.

[Kristofer Björnson @KristoferBj]

@davidbessis Certainly!

[Kristofer Björnson @KristoferBj]

@davidbessis It’s a first order approximation. Effort e should rather be replaced by a function of effort, chance encounters, specific tasks worked on, etc.

@paulg This is great as a physical puzzle. Where the c^2 can be removed and triangles recombined to leave a^2 and b^2 as visible holes.

[Kristofer Björnson @KristoferBj]

@ID_AA_Carmack Getting curious when seeing your chat. What are the main ways you use LLMs? Chat, code generation, auto complete, review?

[Kristofer Björnson @KristoferBj]

@skdh Time ordering isn’t really introduced in QFT, it’s just notation that’s required to allow for the more compact exponential and Taylor series expressions to be written without loss of information. Any parametrized non-commutative algebra needs this when exponentiated.

[Kristofer Björnson @KristoferBj]

@ID_AA_Carmack @fchollet I think there is no contradiction between these two statements. The temporary capacity is larger, but I think @fchollet is talking about the typical information flow. You may be able to detect a flashing frame, but not able to process continuously flashing frames.

@johanknorberg @shorewalker1 @HumanProgress Fantastic!

It seems to be an Asian story, with Collier still being right about Sub-Saharan Africa. It seems that in Asia free markets enabled this. But in Sub-Saharan Africa they already exist? So is it governance that needs improvements there? Opinions? @johanknorberg

[Kristofer Björnson @KristoferBj]

@shorewalker1 @HumanProgress @johanknorberg This seems to still be true at the time of the release, but the trend seems to have broken already a bit before. Anyway, I guess we are all happy about this, including Collier!

[Kristofer Björnson @KristoferBj]

@shorewalker1 @HumanProgress @johanknorberg It’s 16 years since I read it, so my memory is quite fuzzy. What I remember, progress made a a smaller and smaller fraction stuck in poverty, but due to population increase about a billion remained in extreme poverty.

[Kristofer Björnson @KristoferBj]

@bscholl That’s quite reassuring! No worries some random tab freezes while consuming 2GB of RAM.

[Kristofer Björnson @KristoferBj]

@bryan_johnson Let them matter to you

[Kristofer Björnson @KristoferBj]

@PaulRRobichaud I put all my effort into staying ahead of the content in physics, but a very compressed course on complex analysis and Fourier transforms was where my first serious gap developed. I therefore took a year of math courses before returning to physics, and that served me very well!

[Kristofer Björnson @KristoferBj]

@MattButler138 @ocornut @github This conversation is beautiful!

[Kristofer Björnson @KristoferBj]

@jpalioto @davidbessis @NnamdiChukwuma4 @UchCfr522 I doubt this. I relied heavily on geometric intuition for the first year of university math, trying to visualize every proof geometrically. Only later did I fully appreciate a more abstract approach. Never having difficulty to deal with high dimensional spaces etc.
