I’ve been putting in the work in crypto for a while now, and it’s been paying off. To celebrate, I just copped myself a brand-new car! Huge shoutout to @coach_hannahrae my coach, for all the guidance and support. Couldn’t have done it without her.🚘🎉🥳

This is in the police bus that hauled us off when we were arrested. We sang. And laughed. And refused to let the weariness and violence overwhelm us. Joy is an act of resistance. [With handcuffs on, I managed to get my phone out of my pocket and record this little video inside the bus. My pal Ben Cohen (co-founder of Ben & Jerry’s) was also arrested, and was pretty impressed by my Houdini-style maneuver.] Keep singing. Keep laughing. Keep shining in the darkness. Death will not have the final word. Love wins.

Cool and simple proof: Are there two irrationals a & b such that a^b is rational? Consider √2^√2. If it's rational, we're done. If it's irrational then √2^√2^√2=√2^2=2 is rational, we're done. This is a non-constructive existence proof!

It's Mental Math Monday! Math teacher Robin from Michigan wants to know how you would mentally calculate 18×5.

大学院の後輩から部材をもらって作ったもの。立方体のボックスに細いドリルで穴を開け、糸を通して作ったもの。設計と穴あけは後輩による。テグスを100円均一ショップで買ってきて完成。数学的オブジェ、それ以上でも以下でもないですが、綺麗です。

When learning feels like play, understanding grows. Use these games to help students develop partners of 10 through reasoning, strategy, and joy. na2.hubs.ly/H03n_VL0 #MathIsFigureOutAble #MTBoS #ITeachMath #MathEd

So many serious and more important things going on, but our bit of math and art silliness, AL, Logical, a mathy graphic novel goes live on Kickstarter on Wednesday. If you can help us spread the word then, we'd love it. #mathart #mathstory
