Project mention: That is some extremely impressive water physics, especialy for a place you only visit once. How did they do it? (MAJOR SPOILERS FOR 4.2 WORLD QUEST) | /r/Genshin_Impact | 2023-12-02
It kinda reminds me of this fluid simulation website. The site is about a computer graphics technique that simulates the motion and appearance of fluids such as water, smoke or fire. You can use your mouse to move around the screen to see the simulation, also can change how the fluid simulation works by adjusting the sliders in the control panel next to it.

Bullet
Bullet Physics SDK: real-time collision detection and multi-physics simulation for VR, games, visual effects, robotics, machine learning etc.
Project mention: Looking for specific pre-Microsoft Havok Physics SDK version (2013, 2014) | /r/DHExchange | 2023-12-07 -
Well, it's a good video but... Hacker News?
On the related topic, you know how in Ford Mustang the engine noise is simulated so the engine would sound like a pre-emission-standards V8 even if it runs on just four? How about a similar thing for a motorcycle? You put on your noise-canceling head phones, and the phones emit a "noise-canceled" rev of an engine you choose. You can enjoy the sound of a Harley on a moped. And! Since it's your headphones only, you wouldn't even bother the public.
I think there is a startup potential on it somewhere. And the technology is here too: https://github.com/ange-yaghi/engine-sim

OpenWorm
Repository for the main Dockerfile with the OpenWorm software stack and project-wide issues
Project mention: The baffling intelligence of a single cell: The story of E. coli chemotaxis | news.ycombinator.com | 2024-03-21So I have three thoughts about this.
The first is cell specialization, particularly neurons. It seems like nature really came up with a universal neuron. There aren't neurons for eyesight vs thinking, etc. They've experimented with this on frogs where they've reweired the optic nerve to a different part ofd the brain and the frog seems to see just fine. They've even added an eye and the frog seems to cope and use it just fine.
The second is the OpenWorm project [1]. This is an attempt to simulate a relatively simple organism with IIRC ~280 neurons. Despite lots of effort, the simulated version just doesn't match up to the real thing. In artificial neural networks we have a stupidly simplified model of neurons that tends to get reduced to a binary signal and an activation function. Thius can do a lot but it's clearly wholly inadequate for any realistic modelling. The protein interactions in a cell are mind-bogglingly complex.
The third is the three-body problem. To summarize, we have a general solution for the grvity interactions of two bodies. Add one more and we don't. We have classes of solutions but no general solution. This is why JPL needs to use supercomputers to calculate flight plans with a relatively low number of bodies. We see a relatively simple set of interactions lead to massive complexity with protein folding. I imagine that it just won't be computationally viable to simulate even a single realistic cell given all th einteractions that go on. We're simply left to make estimations.
