The first 5 parts get increasingly intense and then part 6 is for fun, as a treat. But feel free to skip around. 1: "Lean? That sounds familiar..." 2: The Mathlib of Babel 3: The part where leopards eat the mathematicians’ faces, and then I mercilessly mock OpenAI which should shrivel up in shame fo

Well, my random pull of a mooncard inspired me to read in bed with you tonight. I'm just responding to an article about AI by Bill Gates, off the cuff, without having prepared or looked ahead. I have some firm negative opinions on parts of it. But I don't want you to feel overly judged if you're som

Another video so soon? Yes, and this one's just for fun, not on a topic I am at all an expert in, just a little window into something I'm excited about on this historic day. Some people have favorite sports figures or musicians they root for to get into their respective halls of fame. Me? I’ve been

I'm in love with this little children's toy that transforms between an animal and a bracelet. Is it because it embodies concepts of graph theory, or is it because sometimes they are sparkly unicorns? ...Yes. Twisty Petz are back in style and I found one in a local store, but you can also make them a

This book showed up at my house and wanted me to help it become a human, and I did my best! I figured there are probably some of you who also have one of these, or who have heard about it, since there's a lot of overlap between my audience and Hank and John Green's audience. If not, the story of the

Quick Patreon Update Patrons won't be charged for this month, which used to be the status quo, but I did say last month that I was going to be more active again because this is my only income right now, so I thought I'd drop a note! (And by "for this month" I mean the March 1st monthly billing, beca

The short version: My videos aren't on YouTube anymore, and won't be coming back. But you can still find them on Vimeo for free, without ads and with no signup required. I may add other places in the future. My vimeo page is here: vimeo.com/vihart I think it's easiest to find stuff in this collectio

I wrote this song pair to capture the feeling of late winter 2025 thawing into spring. Recorded and produced using Audacity, featuring viola, melodica, voice, guitar, some leftover stale crackers, a large body of water, and a triangle. This is the kind of thing that in the old era would have gone on

Hello! First, I have a thank you to you all for the overwhelmingly positive response to my Medium Message on Pi Day. I want to revel in it. I want to roll around in it like a dog in a patch of wildflowers. I know y’all are a pretty cool bunch, and I generally expect that on patreon most people who h

If I had a pi day video for you today, it would be the 15th annual pi day video. 3/14 #15. The Pi Day tradition has been an important one for me, giving me a way to still check in with everyone and not fade away entirely, even when I'm otherwise not making videos or having an online presence. And I

I love autumn, I love Halloween, and I love candy. Not that I like eating it---no smarties were consumed in the making of this video. But in concept, candy still holds the magic of childhood. Candy is fun, and playful, and sometimes aesthetically pleasing to the eyes and the hands. Just like math! A

Printable PDFs for three different kinds of scutoid papercraft are attached! Video instructions are above. Scutoid Pair: Two identical scutoids on one printable sheet. These are based on a 3d model by Laura Taalman, which you can find here: https://www.thingiverse.com/thing:3024272 “Scutoid” is a ge

Hello every human who is here! Remember Scutoids? I’ve been hard at work preparing for Scutoid September. Yes, six years later, it’s finally happening. Many of you have been around that long, and may remember the plans for a scutoid papercraft with instructional video that was going to happen just a

This is adapted from a piece I wrote in 2017 after the August 21st total solar eclipse, which I saw in Oregon. I was reminded of it a couple months ago, as friends and family were talking about their 2024 eclipse plans. That piece is no longer available where it was originally posted, so at first I

There's something special about making fun of pi every Pi Day, and this wasn't going to be the year I stop the tradition. It is, however, the year where I add aliens. I do get a kick out of how long we've been doing this thing. Some of y'all have been here for the better part of a decade, and subscr

Moon Spoon! And... it's a full moon today, too. Moon spoon has been a thing for a couple years now, but like a lot of what I do, I haven't shared it publicly. I'm still figuring out what kind of artist/thinkyperson I want to be in public, what kind of things I want to share or make videos about for

Happy Thanksgiving Week, to those of you in the US! Here's a new video about Crescent Rolls that I made to celebrate. I wanted to share a tradition I have in my family, and share some thoughts about crescent rolls. I like this video, and I hope you can tell that I had fun making it. Behind the scene

Hi! I'm almost done with a new video. It's about crescent rolls, so pick up a tube of those if you want to play along. But here is a notice! I'm currently running an ad revenue test on my channel. To the 326 of you supporting me at the $1 level that reads "You won't see ads on any of my work. Neithe

Why hello again, and so soon! Earlier this month I had this thought about string lights, and so I made this video about it. An earlier version was more classic ranty, but, I didn't like it so I re-did it as a more gentle, repressed rage. Hopefully the end result has a classic vihart feel without bei

Hey! Thanks for sticking around! Today's post is mostly about the music video I just posted on my 2nd channel. I'm also working on a more traditional math-flavored vihart video that will be out soon, so heads up! This mostly-dormant Patreon will actually collect your support on Nov 1. Thanks in adva

Hi, it’s me, triangle. Pi Day has come around once again. That’s a lot of times now! Thanks for sticking around with me through another year of this tradition. Life may change, but Pi stays the same. …or does it? For the 13th annual Pi Day video, I thought I’d get back to my roots and enjoy a story

Hi! 1. There is a new video! It's been a real long time since I did a classic video-making binge. Days of script writing, finessing the script and the narration, filming, editing, all in one all-encompassing creative flow with long hours and no distractions. It was inspired by this video Hank Green

Hey everyone, Two months ago the video I was working on for Tau day was a fun one. One month ago that video got scrapped, and I did several drafts of a very different video. A story for another time, maybe. One week ago the plan changed again. So this is the video that happened. I suspended payments

Welcome to another episode of “why am I like this, why do I spend my time on things like this when I could be spending my time on things that are beautiful and good”. But it’s still Pi season, and with the end of March looming I somehow decided this is what I needed to do. And so I did. And because

Another video already? Yes. I thought it'd take longer, because the footage I captured felt like a mess and I thought I'd have to start over, maybe with a proper script. But once I got into the editing groove it only took a couple days to wrangle the footage into something that works. Or at least I

This is my 12th annual Pi Day video. Our Pi Day celebrations are perhaps the most consistent thing in my life, and part of me is always surprised how I manage to follow through year after year. A few years into this, when people started commenting on how they’re looking forward to Pi Day even if I h

I’ve decided that this time is not like any other time. I’ve decided to mark the moment and make some big and positive changes in my own life, and also change up how I relate to the world and all of its world stuff. So! Where to begin, today on this one and only Friday March 11th, 2022? Here’s the h

It's Twos-Day Tuesday! Y'all know I can't resist a good math holiday. I don't often participate in collab videos, but I was already set up to film for Pi Day and I was in the filming mood, so I was able to take part and create a two-minute segment for this Twos-Day Tuesday collab organized by Matt P

I've been working hard this month on this year's Pi Day video, and learning the ropes on some of the updated equipment y'all have funded for me the past couple months (Thank you!). When I remembered this classic topological love test, I felt inspired. After being in production mode for a more diffic

Hello everybody! How do I explain this video? All I know is that it is very much itself. If you haven't seen the previous video about the BTS Octahedron, you might want to start there: https://www.youtube.com/watch?v=YPKUbfIrlL8 Thank you for supporting this video! It ended up taking quite a bit mor

Oh hello human peoples! Happy Belated Tau Day! I have a video I've been working on the past month which I was hoping to get done in time, because even though Tau Day videos are much less of a thing than Pi Day videos around here, I still wanted to celebrate with you all. But it turns out it's a much

New video! And, as we've decided is how we do things around here, new video means I'm letting payments go through for the month, so you are officially supporting the creation of Octahedra everywhere. Ok, y'all know I love a good shape. But what you might NOT have known is that I also love BTS. I fir

My friends, we have made it to another Pi Day! The world today is different than it was a year ago. I'm glad you're still with me, and I wanted to mark the occasion with more than just the regular kind of Pi Day video. So in this year's video, after the usual fun notebook doodles and rambling, I've

Hey you humans, Sometimes I think I gotta sit down and write a proper post about all that's been going on, but as you may have noticed this Patreon page has been suspended for a long while, and not collecting pledges while I work a million works. I don't want to try to narratize about this past year

A month ago I became involved in a bipartisan effort to really understand what it would take to get through the COVID-19 crisis in the US. My first contribution was helping write a white paper on digital contact tracing. It was inspiring and humbling to work with so many incredible folks jumping in

Hey all you good humans, Difficult to believe that Pi Day was just three weeks ago, when I wrote about how my goal with the Pi Day video this year was to sneakily get PSA info to people who weren't taking COVID-19 seriously and weren't seeking out information about it. In the days after Pi Day, the

Hello Good Humans! It's Pi Day (or almost, depending on your time zone), and the annual Pi Day video is now live! $$$ alert: I haven't been charging y'all for the past few months, but since I made a "real" vihart video this month I'm going to turn it back on for the April 1 charge, and then turn it

Hello good humans! A reminder this Patreon is currently not collecting pledges, as I have a full time job that is not this. But, since my job has involved a lot of paperworky things lately, apparently my brain exploded into the creative outlet of making videos analyzing The Witcher, soooo I did that

Hello good humans! It's been a while since I published a video, and I know this won't be everyone's cup of tea... but I've always enjoyed watching other people's in-depth analyses of movies and TV so I thought I'd have fun and try something new. I'm meh about most TV and movies, but I just watched T

Hello good humans! I'm pausing the billing on this Patreon; you will not be charged in January 2020! 🎉🎉🎉 This is because things are going well for me and I've decided to dig deeper into some of the research and collaborations I've got going on. I'll let you know a little more about that once thin

Today I'll let art do the talking, since I never know how to write word-based updates when my work updates aren't straightforward, especially since I don't write about things that are not work. My life is going JUST FINE, seriously, here is some arts. The featured video compiles some footage from th
