How to roll Crescent Rolls Vihart 2023-11-23 | Pillsbury Crescent rolls featured in my latest video, and a lot of people are finding it by google searching how to roll crescent rolls. It is not what they wanted. Please google, show them this one instead.The original video is here: youtu.be/dpFEegAIFrI

I have opinions about string light colors Vihart 2023-10-26 | It's fine though.Bonus exercises for those who absolutely will continue to overthink this for the rest of their lives:1. If you have a 150 light strand with 5 “Christmas” colors, and decide to remove all the pink ones and make it a 4 color pattern, what’s the minimum number of lights you’ll have to replace/move? Can you generalize to any number of lights and colors?2. Choose, or create, a holiday that doesn’t have string lights as part of its standard decor… yet. Decide what colors the lights should be, considering how the colors will mix and light the room. Get as detailed about frequency, spectrum, and incandescent vs led considerations as you want.3. Remember how you could think of chasing light patterns as moving slowly in one direction, faster in the other, or even faster in the original direction? How far does this go? Can you come up with a way to describe this, for different numbers of lights and different chase patterns?4. Create something that has the vibe of string lights with different colors and chase patterns. Use a musical instrument, a computer program, makeup, dance, or any medium you enjoy. It could use simple blobs of color, plain text numbers, sounds, or movements.5. Say you have 3 spider light factories, each of which exclusively makes one color of light: orange, purple, and green. If you are producing 3 different colors for 10 bulb string lights that start and end with orange, how much efficiency are you losing by having idle factories that don’t need to produce as many purple and green spiders?6. Prove irrefutably that spiders are a christmas animal.This Video was supported by viewers like you, on Patreon.

chickensalad.mp4 Vihart 2022-06-28 | Just a casual chat about abortion while making chicken salad. Here's a link I found that's pretty good, if you're looking for calls to action: bit.ly/RoeWYCDUsually my videos are funded by Patreon, but this one isn't, because that could be awkward for the folks I might usually name as funders. So. Patreon payments are suspended for this one. And since I don't make money on youtube or run youtube ads, this one's just a quick low-budget statement for those who are wondering my position on this issue. Now you know!Chicken salad includes:Half mayo, half yogurt (for sandwiches, lean toward mayo. For eating straight, lean toward yogurt.)Celery, green onion, apple (grapes work great too)freshly toasted slivered almonds (this is like the tastiest secret to great chicken salad)seasoned to taste with salt, pepper, mustard, turmeric, cayenne, whatever else you want because it is your salad and you deserve delicious snacks

Magic Heart Love Test - using two strips of paper, tape, and scissors. Vihart 2022-02-12 | Is your love compatible? Do the forces of topology and mathematics smile upon your pairing? Find out with this classic mobius strip love test.I learned this from Mike Caputo in around 2010, and as far as I know he originated this trick, or was an early popularizer of it, in his 1990 article in the Jan/Feb edition of The Oregon Mathematics Teacher (and if anyone can find this article maybe it will give more insight). I blogged about it in Feb 2011 after teaching it in a workshop when I was Mathemusician in Residence at Harvard's Pforzheimer House (anyone here from those days? Hello!), but unfortunately all the links in that post are now dead (as is the blog itself) and my memory is fuzzy. So if you have info to share please send me a note!But just to keep as much of the history and attribution as I can, here's the dead links I have for Mike: http://teach.beaverton.k12.or.us/~mike_caputo and for the article: octm.org/TOMT.html I've seen a number of great videos on this in the past ten years, but none that capture quite the spirit and framing of the original love test in the way I remember it. Or maybe this is never how it originally was and I made it all up. No idea, but I had fun making this and I hope you had fun watching it :DAnd an extra special Valentine's Day thanks to my Patreon patrons, whose support make this possible. Thank you Ray Sidney, Pat Devlin, David Perryman, Andew Romaner, Andrea Bi Biagio, Jodi Vezzetti, Yana Chernobilsky, David Smith, Alan Boulton, Nancy Blachman, and Caleb Wright, for your extra support!You can support this work here: patreon.com/vihart

You give me faith that BTS Octahedra need to exist too.

Don't forget to speak out, call your representatives, and keep an eye on 2018.I'd love to see someone with access to finer grained data follow up on some of this!Comments closed because there were too many of the same partisan reactions you see everywhere else, and that doesn't help anyone consider new perspectives. But I encourage discussion of this video in a longer less-shallow form than the YouTube comment system can provide, especially doing it in real life with people you know.Looking for a way to expand your community interactions to include more diverse age ranges?
