I think a relatively simple explanation is that on one hand mercury is liquid due to its closed-shell (a bit "noble-gas-like") electron configuration: [Xe] 4f14 5d10 6s2 and that it since its electrons are paired it makes it less

The 128 bit arithmetic part is really interesting. I wonder whether they used libquadmath and whether they needed to implement any extra funcitons beyond what’s available there.

In the process of “shut up and calculate” (SUAC) you often come upon much deeper insights about the involved processes and quantities than you ever could with wordy and “understandable” explanations. Of course simple, explainable models are

I don’t have full explanation of the connection that would be satisfying. However, I think it mainly comes down to symmetry group of the spinors and their 720 degrees symmetry. It is called plate trick for a reason after all: https:/&

I find Julia’s Pluto to be reasonably close alternative. Of course it lacks many features, but plugins systems and overall architecture gives hope for possible extension to include many of the desired features.

This is of course very true but doesn’t take into account invention of computer that is relatively recent. Since it in principle never makes mistakes (in practice there are of course bugs, but they are usually different in nature than human

Chess programming is fascinating but it seems for me that it has somewhat stalled in creativity in terms of classical (non DNN) engines. They all seem to use improved versions of min-max/alpha-beta. Which results in computer players th

Wow, thanks! I had no idea it existed. I’ve searched for something like it not that long ago.

Mathpix is a great product that perfectly fills its niche and I’m very happy it exists. I wish some open source alternative existed. Even much less accurate would be quite useful. I know latexify but it does only single symbols. Maybe it wi

Yes! Those are exactly some of the alternative frameworks I had in mind. Also things like using differential algebra instead of classical epsilon-delta analysis and using Liouville's theorem to calculate integrals gives similar vibes.

I absoultely admire creativity and skills it takes to pursue developement of novel branch/framework of mathematics like this Super Calculus. I think that such original thinking at the fundamentals of mathematical formulations that unde

In Europe this is required in European grants, but also in many country specific funding agencies as well. In 2018, 11 European research-funding organizations formed what is known as cOAlition S with the primary objective to ensure full, im

How I wish papers in science and engineering were written in such format (or were created with org-mode source files with code which one could download and play with), where we could preview steps of derivations in some symbolic manipulatio

Have you checked beorgapp? I find that it supports surprisingly large parts of org mode.

I’m in similar situation. Didn’t upgrade from Mojave and like my system so far but wondering where to go from here. What competition would you recommend in terms of hardware+system?

The difference is, that there's very advanced mathematics behind string theory and at leas that part can be checked/verified by independent researchers.

But aren’t the shorts for like 140% of the GME stock? That means if everyone holds with prices, sooner or later the shorters will have to buy ALL that stock anyway at nearly any price to cover for the losses and give back shorted stock.

I also like pipe syntax and I've found there is nice support for it in Julia. There are some nice packages to improve it over base [1]. Have you checked queryverse [2]? [1] https://github.com/jkrumbiegel/Chain.jl

What kind of alternative to maths and models, that has predictive (preferably in quantitative way) power, would you propose?
24.
by tikej 6y ago
Why wouldn’t it be pursued? Is string theory not pursued by “mainstream science” because (at least for now) it has less predictive power than standard model?

Sure it is valid, but in reality most scientists don’t religiously stick to Ockham’s razor and oppose alternative theories that give correct predictions. If hard sticking to Ockham’s razor was true, Quantum loop Gravity, String Theory and m

This text mainly shows that author either misunderstands chess, probability and science, likely at the same time, or just wants to critique for critique’s sake. Of course while it’s good to search for alternative models/theories/e

If getting as many as possible and as big as possible grants is incentivised, that isn’t a surprise. More permanent positions, longer funding (like for 10 years), funding good people, letting them do risky projects without penalising them

Julia is kind of nice example of what’s possible with dynamic language and static types.
