Correct me if i am not wrong they probably defining initial conditions for the particles (such as positions (to create the spongebob (althought I wish there was a way to convert an image to these n bodies), velocities, and masses)
Then you set up the gravitational interactions between them and futher iteratively update their positions and velocities over time using some numerical integration method (Euler's method/Runge-Kutta method?) to simulate their motion
Looks like it. A.K. Dewdney did a computer recreations column in Scientific American back in the eighties with a nice exposition of how to do a basic star cluster simulation. Only practical with a lot fewer “stars” on the gear I had available then. It used Euler’s method iirc.
I have a copy of The Magic Machine on my shelf which I (unintentionally) stole from my university library at the end of my senior year. His work was pretty influential on me, inspiring me to keep exploring programming at a time when my day to day work in the subject was often painfully boring.
Speaking of which, Dewdney recently passed away on March 9th but I haven't seen any notice of it on HN or other CS-related sites. I know he alienated a lot of people with his unfortunate turn to conspiracy theory after 9/11, but he really contributed a lot to popular interest in CS and recreational mathematics in the 1980s and 1990s through his Scientific American articles and his books.
I was going to link to the article about sympletic integration, but it's toooo technical. This other article explains the problem https://en.wikipedia.org/wiki/Energy_drift
One of my close friends (Ivy League guy) did the same with his PhD thesis on Siamese networks in improving robotic perception. With the final presentation upcoming, in 2-3 days he's got a whole polished thesis ready to go and even convinced his guide that this was what he was working on it since 3 months. He was recently offered a doctorate
I wonder how many people adeptly use GPTs and manage to navigate through their academic landscapes nowadays. I bet its majority

The yellow section in the video dissolved a bit earlier than I anticipated, around 0:23, but I noticed that there are a few missing pixels on the left edge. It could be due to lower resolution or the need for clearer indications. Perhaps improving either the resolution or providing clearer visual cues, such as eliminating shaded edges on the border, could enhance the experience. But sitll, I find this variation of Tetris with sand elements to be quite fascinating and a unique twist on the traditional game. Great job bro!
The feature to register arbitrary Python functions as scalar functions within SQL queries is pretty insane. Writing custom functions to manipulate data in ways that aren't possible with SQL, basically without fetching all of it at once in memory and then applying. I hope thats the case
