Pretty sweet #MathSky

1st panel shows Buzz Lightyear captioned “what if I’m not smart enough to do math?” 2nd panel shows an infinite looking shelf of cloned Buzz Lightyears captioned “every mathematician”

4-panel meme. 1st panel - Superintendent Chalmers saying “So du/dt=du/dx dx/dt?" 2nd panel - Principal Skinner saying “Yes.” 3rd panel - Superintendent Chalmers saying “So du/dx is a fraction?” 4th panel - Principal Skinner saying “No.”

Poor calculus students #MathSky

Not sure what you mean by source, as I made this meme. That is a great book though!

4-panel Power Puff Girl Mixing Meme. The first panel shows a character adding sugar captioned "topology χ(M)", second panel shows character adding spices captioned "Geometry K k_g", third panel shows character adding in "Analysis integral symbol", and the 4th panel shows a monster captioned "Gauss-Bonnet". Below is the statement of the Gauss-Bonnet theorem: integral_M KdA+integral_{boundary M}k_g dx = 2πχ(M).

Such a cool theorem

A page of a calculus textbook showing an example of using L'Hopital's rule. On the page is a popup with text "Sorry, L’Hôpital’s rule isn’t available right now. A law banning L’Hôpital’s rule has been enacted in the U.S. Unfortunately, that means you’ll need to find another method. Calculus students are eagerly working to get L’Hôpital’s rule reinstated. Please stay tuned! Learn more. Close"

Wow...they really banned it 😭

2 characters carrying another character in a stretcher. The characters are saying "What happened to him?" and "He found out (3&6\\0&1)(5&4\\0&2)=(3\cdot 5&6\cdot 4 \\ 0\cdot 0&1\cdot2)". The character in the stretcher is captioned "Mathematician".

Cursed matrix multiplication

A dog standing on 4 cans. The dog is captioned “group theory”. The cans are captioned “for all a,b in G, ab in G”, “for all a,b,c in G (ab)c=a(bc)”, “for all a in G there exists b in G ab=e=ba”, and “there exists e in G for all a in G ea=a=ae”.

From only a few simple axioms, we get all of group theory #MathSky

The text "I heard the MathMatize booth is giving out Hagoromo chalk". Below is a picture of a person whispering in another person's ear next to a picture of an arm with goosebumps.

Hey #MathSky, if you'll be at #JMM2025 please stop by my exhibition booth. MathMatize has come a long way, and I'd love to share how it's being used in math classrooms around the world.

I'll also be accepting chess challengers, and am handing out travel-ready Hagoromo chalk 🤠🤠
