for context -- to reboot an MRI can cost about $200K in direct costs, but this does not include scan-time loss for patients and rescheduling costs.

I've been wanting to make a video just nerding out about MRIs for years now :/ they are so cool

Today I learned that because MRIs are superconducting, they are cheap to keep going but *very* expensive to turn off/on. They are only ever turned off in a life-threatening emergency and can take a week to bring back online.

This means the MRI scene in the newest final destination makes no sense.

Playing around with some ways to render the next video topic. This may or may not end up in the video but I liked how it looked.

✨ New preprint from the lab on firefly synchronization, led by Owen Martin (freshly Dr. Martin!), with Nataliya Nechyporenko and Kaushik Jayaram.

Our measured firefly phase-response curves reveal excitatory and inhibitory timing rules that facilitate population synchrony ✨

yesterday I was on my way to work and I saw two trains pass going my direction. I probably could have made the second one but thought I'm in no rush and I have a book with me and at least I know the trains are moving. That was the last train for an hour because of an accident downtown -_-

For anyone looking for a happy/carefree album to get through *the times*. This is my favourite track which is maybe a bit more melancholy but the whole album is a genuine treat

For me its less the sound of my voice and more the realization of the variety of aweful slurpy/clicky/generally unpleasant sounds the human mouth makes that you normally don't hear but the mic absolutely LOVES to pick up.

The painting sound thing might just be one of the most beautiful things I've seen on youtube, this was such an amazing video.

English was the third I learned growning up and my first two were both gendered languages. Even still, I don't know if this is a hot take but in my opinion its the one of the few things English has going for it.

For the US CDC's it was shoes off (its in the video). I'm 90% certain for the metric folks it was also shoes off, but I don't remember that one as well and it wasn't from a single source. Given these are often taken to monitor population health I hope they are doing it shoes off.

I did have a dataset of basketball players but it was... wierd. I can't remember how, its been so long now, but it made me switch to a hockey dataset I had instead

thank you! I went through quite a few itterations of these. Drawing one histogram is fine but when you have to have like 6 of them on the screen at the same time I had to be a bit more creative about it.

My favourite part of uploading a new video is the first thing that happens is you lose subscribers haha

Thank you! You're the first one to give feedback haha glad you enjoyed it :)
Thats what I thought too. Someone suggested its because marking events on the line makes rulings like off-side ambiguous. So there's a bias against it marking on the line, which also makes sense.

Ceave is so talented holy. I'm not a big gamer, but using Mario to frame prime factorization is so good. Like math? Its a good video. No interest in math? That's fine, it's just a video about Mario. And it'll certainly reach someone who thought they hated math www.youtube.com/watch?v=JrBe...

"Kate: Frankly, what I imagine is one of us will die from stress, and the life insurance will pay things off.
Tom: Yeah, we have good life insurance. We’re better off dead.
Kate: Right. [Laughter.]"

I don't know if I've ever felt so much pain imbued into text as I did when reading "[Laughter.]"
