🚨🚨 #MathTwitter Announcement! 🚨🚨 As I'm going through and finalizing chapters in my #VisualAlgebra book, I'm recording a new set of YouTube videos in tandem. This will be more than twice as long as my existing #VisualGroupTheory playlist, with MUCH more content. 1/3 👇

What makes a great mathy cartoon? Ben Orlin from the blog Math with Bad Drawings shows us how to make our very own mathematical cartoons in the latest #MathValues! #MathTwitter

Lately, I’ve been missing #MathTwitter. Is it gone? Does it live on somewhere in here? I’ve been so hard pressed to find math and academic related posts on my algorithm :/

Teaching derived categories means there are a number of technical fine points I finally understand after (checks calendar) 29 years and five months of using them. #MathTwitter

Hey #MathTwitter, let's talk (group) Isomorphism Theorems, which I did in class yesterday. I want to CONVINCE you that they're always in the wrong order, and there should be (gasp!) 5 of them. I'll end this thread with a question for all of you. Let's get started! 🧵👇 1/12

Grothendieck's prime #mathtwitter

Geography fun! Go to the website to see how map projections distort reality. I hope every #geographyteacher and #mathtwitter know about this. Source:

π ≈ 3.14 But why??? पण का??? #MathTwitter

On the 121st day of the year, we are presented with this remarkable representation of the number 121. #Mathematics #Mathtwitter #Today

In today's Abstract Algebra class, I introduced automorphisms and semidirect products, despite us not having defined a homomorphism yet. Students should see the intuition behind the concepts, the motivation for them, and the inherent BEAUTY that is too often missed. #MathTwitter

When the instructor forgets the proof in the middle of class #mathtwitter

Ok #MathTwitter, this semester has completely burned the love of math out of me and I am sad. What's a fun expository or intro book to get back into it over winter break? What readings would you recommend to someone who knows nothing about your area of study?

No board no problem, chalk markers to the rescue! #mathtwitter #hotmathsummer

Find a unique value of 'x' that satisfies the interesting exponential function equation below. #mathematics #Mathtwitter #weekendfun

A beautiful theme across mathematics is "conjugation preserves structure". How do we impart this knowledge in a memorable way that students will truly understand? My attempt, after introducing conjugacy classes yesterday. Feel free to use/adapt in your own class! #MathTwitter

Hey #MathTwitter! Here's a little something inspired by @matthematician's "is-it-a-sandwich" activity and #HoagieHomies everywhere. 🥪 What makes a number, a NUMBER? Would love to hear your thoughts! 🙂
