🧵 My 3rd book is now out! It is on the fascinating history of math. How did people throughout history think about math?What problems did they care about? How did they express them? How were they solved? This book includes a lot of historical math. a.co/d/gsoNKxP

I'm back to posting YouTube videos on my proofs book. Just started chapter 3, on sets! youtu.be/xUt-2nEacYM?si…

Two of my students are in a band and they made a cover of my math history song. I love it so much. Check it out: youtube.com/watch?v=Regahz…

I might have a new favorite proof that the harmonic series diverges. It's just so beautiful.

In the age of AI writing, it is more important than ever to emphasize this to the next generation. Writing is not a simple record of what you think---it is one of the best ways to learn. And it is a means to uncover what you didn't know you believed.

Showed my kids their first two Counterexamples in Analysis. Brains broken. Me happy.

ICYMI: I wrote a math history song. (And I think it's actually pretty damn good!) You can watch the music video on YouTube: youtube.com/watch?v=0KrT_V… Or listen on Spotify: open.spotify.com/album/3MEbKXC5…

Little news: I wrote a song! It is a math history version of Billy Joel's "We Didn't Start the Fire." I then got Tom Bedlam to perform it, and I turned that into a music video. Check it out! I hope you enjoy it! youtube.com/watch?v=0KrT_V…

My latest YouTube video discusses why we prove things in math. Check it out! (And subscribe! I have a math music video that I plan to post next Wednesday that I think you will enjoy! 😃) youtube.com/watch?v=2QcJB-…

@LukeMacon One page at a time

@LongFormMath Yall write lots of books whats your secret

My kiddo and I recently finished our 100th chapter book. :-) It’s been so fun, but I am running low on book ideas. Do you have recommendations? Ideally we want an early chapter book with lots of pictures, but feel free to suggest others too! Here’s what we’ve read:

@CharleySeymour6 I hope you’re enjoying it!

@LongFormMath I hope this is good! 😁

@iplaygamesbadly Nine?! Amazing!

@LongFormMath My nine year old is going to be very excited to watch this tomorrow. He loved the Proofs book and just today he was talking about a problem in class that he remembered seeing in the book.

I am starting a sequence of videos on my YouTube channel in which I will cover the main content of my Proofs book. In the first video, I argue that learning proofs amounts to a "phase change" in your math eduction. Please check it out and subscribe! youtube.com/watch?v=HbUagv…

@MathsNinja24 There was a problem uploading it. And then I got busy and forgot to go back and figure out what the issue was. Sorry! Will get to it soon!

If you're at MathFest, please stop by the exhibition hall! I'm here cosplaying a real publisher.

@IAmSamFin Yes—thanks! We loved them but after 23 he suddenly lost interest and wanted to read something else. I hope we return to them though, they’re great!

@LongFormMath Of course! Also, you may know this but there are now 29 dragon master books and the next one comes out in December (I saw 23 listed in your first tweet, don’t know if you stopped intentionally after shadow dragon or they hadn’t come out yet)

@dcwuser Thank you!!

@LongFormMath For a mathematician, Phantom Tollbooth is a must.

@DJWebbMath Thank you!!

@LongFormMath It is somewhat illustrated, and probably about the difficulty of The Lion, The Witch, and the Wardrobe

@__vren__ Wonderful! Thank you!

@LongFormMath (this was the first childhood book that hooked me, inspiring a habit of sneaking away to read)

@MihaiCNica Thank you!

@LongFormMath Oh I just remembered another series we liked! Its called "Zoe and Sassafras" and it's about a girl who learns about the scientific method but applied to helping magical creatures. It's really great
