Show HN: Stemformulas.com

During my (ongoing) engineering degree, I've often looked up formulas and been frustrated at the lack of reliable results. Some formulas (usually the easy ones) get their own blurb on Google results, while others are a few clicks away, or are most easily accessed by looking at random university slides on Google images.

It felt like, in this day and age, there should be a site that serves the small but noble purpose of being a source of truth for formulas, while leveraging modern website technology to provide a fast and user-friendly experience.

So, I made stemformulas.com (with some friends)! It's a really simple website, basically just collection of formulas with a search bar. The formulas are displayed in LaTeX, they're double checked by me against sources that I link for further reading, and I write out all the variable definitions for each one. A feature I recently added was the ability to copy the LaTeX on any formula page (e.g. go to https://stemformulas.com/formulas/schrodingers-equation/ and click on any LaTeX). LLMs aren't great at getting complex LaTeX right yet, so this felt like a nice value add for users.

I've been using this site as basically just a personal hashmap of formulas, but I think it has the potential to help others as well, so I'm hoping to get feedback, formula suggestions, and maybe even some contributors with this post.

If you're interested, the source code for the project is available on GitHub at: https://github.com/stemformulas/stemformulas.github.io

Thank you all!
