Carbon, oxygen, hydrogen, nitrogen, phosphorus and sulfur make up the bulk of organic molecules and plenty of those are covered by world wide patents (drugs).

I'll link to another reply of mine: https://news.ycombinator.com/item?id=36966474 The "just a function of" is a non-trivial problem. Given a single set of elements you want to "try out" results in a

Some context on VASP from someone who worked with it for about 10 years. VASP is a very common projector augmented wave (PAW) planewave DFT program in the solid state physics/chemistry community. I used it for about 10 years when I was

Crystal structure prediction by itself is a very hard problem. Just given the chemical formula and asking "what is the most stable structure" is a global optimization problem. And this is just for one single composition. It isn&#x

The thing that stands out to me is that the DFT simulations show that the flat bands only occur in a particular crystal structure of the material and it is not the most stable state (at least according to the simulation). This would explain

Theory confirming experiment is quite different from theory predicting new physics. I think the best use of these types of ab initio DFT calculations is to interpret experimental results. Back in grad school, my theoretical chemistry group

Most science is way too boring and requires way to much work to reproduce to follow this kind of model. This open science type work we are seeing for LK-99 works fantastically when a huge number of scientists are interested in the problem a

In order for a wheel to be used instead of a source distribution there needs to be one that matches your environment. For numpy you can take a look at the wheels for their latest release[1]. The filename of a wheel specifies where it can be

This sounds like an amazing project. Thank you very much for sharing it here. You should be proud! Few people can really point to a project and say "people use this and its a genuine improvement." The world needs more people like

How can you be sure that your constraint model is correct? When the models are so complex that seems like a real challenge! In your case was it possible to take a proposed solution and verify that it does not have any issues? Are there many

Others have said something similar, but I will still chime in. It sounds like you may want to feel like you have a complete understanding of classes, objects, and the way the work before you can begin working with them. This can almost neve

I do not take criticism of my work personally. I think this is because I have already heavily criticized it myself. Everything I make falls short of the ideal form I have pictured in my head. This applies to code, woodworking projects, CAD

I'd love a source for this claim (not sarcastic, I really would). I've have done a lot of testing of LEDs for scientific uses and my experience and what I've read show that temperature is what effects the center wavelength of

I really enjoy speaking with native English speakers from India. Fully mastery of the language, but with different idioms! For example "do the needful"[1] https://ell.stackexchange.com/questions/17621/do-

I will heavily second this opinion. I'm not an electrical engineer, but I do prototype some electronics that eventually become products. One of the most important factors to me when selecting an individual component is that it will be

This post made me realize why I am hesitant to leave my role in a struggling start up. I get paid to discover what our problems are and solve them as fast as possible which leads me to constantly learning new skills and fully owning our pro

I'll give two examples of code I could for sure write myself but that I had gpt4 write for me because I figured it would be faster (and it was). The first one was to write a python script to watch a list of files given as cmd line argu

For clarity, loperamide, sold under the brand name Imodium, is an anti diarrhea medication. It is an opioid; however, it does not readily cross the blood-brain barrier. It only acts on the opioid receptors in the large intestine and slows t

Small tangent. Would you mind sharing how you calculate CPI? Do you just do timing and use some base clock rate? With the CPU frequency being so variable (with boost clocks) I imagine the correct way is with some fancy instrumentation.

I only have experience with PCBWay. I'm not associated with them at all, but their service is amazing. I've ordered (in 50+ quantities) five different 3d printed parts. In my case I chose MJF (multijet fusion) as I wanted a semi-p

I think a system of springs is a good example. I think having a bunch of springs hooked together is a bit abstract so let's instead think of a molecule and model the bonds between the atoms as springs. If you were to squeeze this molec

It may sound like it, but the term is in common use. Google "body doubling" and you will see many articles on the topic in connection to ADD.

I think a worked example of a simple problem with some accompanying visualizations would make this a more complete introduction. Links to learn more would be nice too. As it stands it feels half done.
