Video out imminently, feedback urgently requested
Added 2022-11-02 22:44:29 +0000 UTCHello wonderful Patrons,
We have a new video coming out very soon, and we'd love your feedback.
Here's the link -- https://youtu.be/BBqMB2-NdCk
What do you think of it? Are we making any errors? Anything bothering you? Anything not clear? Does the story check out? There's a lot of math, and we've done our best to get it right, but it's possible some mistakes have slipped through -- please help us find them.
Thanks,
Petr on behalf of Derek, Emily, Ivy, Albert, Jakub, Fabio, and Alex who actually made this video

Never pardon your puns. Be proud of them! :)

2022-11-03 19:43:45 +0000 UTCAwesome video. I particularly like how you find a pretty compelling way to make the relevance of the FFT come alive. The usual "you use it when you use your cell phone..." kinds of examples are good, but this one is (pardon the pun) powerful. Meanwhile, a couple of comments about the video: 1) it probably isn't that important, but the standard wrap-around you get in the plots (see, for example, around 11:38) isn't mentioned or explained and 2) I agree with some of the other posts that the explanation of the Fourier Transform is one of the best I've seen (even Grant is probably applauding you) but that the _Fast_ FT explanation is, well, a little _too_ fast. So for example, showing you only need to do 2 multiplies at around 16:34 might be extended to show it individually for F1, then F2, then F3...then layer those frequencies on top of each other to illustrate their all the same, _then_ show the other points that are also the same calculation. Finally, it's too late for big content changes but there's another overlap between the relationship of the FT to war and the FFT to war, namely (if memory serves) that Joseph Fourier created the FT to deal with heat transfer in Napoleon's cannons to try to speed things up. And then, just for a tiny tiny silver lining, there's RadioLab's or Nova's episodes on the "bomb pulse" that has powered some important biology research (see https://www.pbs.org/wgbh/nova/article/bomb-pulse/). Superb job, as always.
2022-11-03 14:54:33 +0000 UTCSorry for the late advice, but I'm not clear on the Y axis of the histogram at 4:29. Is it supposed to be number of bombs donated above or below ground? Edit: It became more clear as I continued to watch... But I was uncertain at first.
