| Solving the N-pendulum algebraically. &[Wolfram Notebook][1] [1]: https://www.wolframcloud.com/obj/61a8da15-3502-4d34-a1b8-b3bb505ed0e1 |
| I think the ability to do symbolic math is underrated. I'm a hobbyist programmer, and I once encountered a problem that really did require to do symbolic math. I really, really didn't want to do the calculations with pen and paper so I bought a... |
| I think the 109 values you call "tests" are usually called the validation set, but this is a matter of nomenclature. In any case, I am surprised this can work at all. I've always thought market prices are more or less random walks. In fact, I'm... |
| > This is easily modeled with two IdealGearR2T blocks -- one with a 1:1 ratio to move from translation to rotation with no ratio and a second one to go from rotation back to translation with a 1:2 ratio (output is twice the input). The two blocks... |
| It could be related to an issue I noticed today: when writing a title the cursor seems off. It lags behind the actual typed characters. The difference increases with the length of the typed string. It's like the position of the cursor is... |
| Some time ago, before I had a Mathematica license, I solved the classical pendulum problem with only algebra and rational numbers : http://grondilu.github.io/pendulum.html I was inspired by Norman Wildberger who advocates on YouTube for what he... |
| Makes sense. I feel silly because I should have guessed that. Thanks. |
| Hi, I was experimenting with `NetGANOperator` and the training seemed to work fine as the loss function results were evolving more or less as I would have expected. However, when training was done, I tried to generate images from a few latent... |
| [DictionnaryLookup][1] searches for dictionary entries matching a given spelling pattern, but is there a way to search for entries matching a given *phonetic* pattern, possibly using the international phonetic alphabet instead of the dictionary's... |
| I didn't know about Z-curves, thanks. Here is my attempt at implementing it in the Wolfram language : ZCurve[seq_String] := ListLinePlot3D[ Transpose[ { (#[["A"]] + #[["G"]]) - (#[["C"]] + #[["T"]]), ... |
