Here's a short dynamics-based explanation of the equation e^(πi)=-1
First (and hopefully not last 😅) blog post of the new year: want to understand logarithms intuitively? Then start thinking about them as clocks ⏰ Thanks to @stevenstrogatz and @3blue1brown for looking over a first draft: mehta-rohan.com/writings/blog_… (1/2)
#ma205 infinity is part of Wednesday's exam! youtu.be/Vp570S6Plt8
Finally some reasonable suggestions! Don’t cite it as an author, describe in detail how the tool was used. Makes a great deal of sense to me in many of writing applications. nature.com/articles/d4158…
#ma205 this is the difference between a conditional and its converse, as we spoke about in class Friday! More on converse errors and arguments to come in the next few weeks of discrete math!
Take a circle in the complex plane, and average each point on it with its reciprocal. The result looks like an airfoil! johndcook.com/blog/2023/01/2…
Doubtlier, gaboratory, whenure, coffree. Start the new year off with words you didn’t know you needed. scim.ag/15e @ScienceCareers
To demonstrate how computers work, Alex Gorischek has made a physical example of how binary logic gates work using pulleys and weights. For anyone who doesn’t know much about logic gates, it’s a great lesson in one of the fundamentals of circuitry [video: ow.ly/WTvD30obozP]
Good grief! The day before Charles M. Schulz's 100th birthday, it's a DORK TOWER FRIDAY, at the mothership! dorktower.com/2022/11/25/goo… RT (please and thank you - it's a huge help), but most of all...rats!

#ma225, we’ll look at the ideas of distances this month!
How to download academic papers and books for free
#ma342 we will get to this before the end of the semester!
Oldies but goldies: E. W. Dijkstra, A note on two problems in connexion with graphs, 1959. Dijkstra’s algorithm computes the geodesic distance on a graph in O(n*log(n)) operations using a front propagation algorithm. en.wikipedia.org/wiki/Dijkstra%…
So all of this to say: There is trauma in the running. There is trauma in the running. There is trauma in the running. And we have to do more. (21/21)
One of my favorite Disney films! I have a VHS I taped off of the Disney channel decades ago!

A topological magic trick. (Mathematical explanation in the next tweet.)
Going to make sure my fall class sees this.
My matrix visualizations with MIT Gilbert Strang. I compiled the graphics in a short(14-page) PDF paper! github.com/kenjihiranabe/…

Three cheers for linear algebra in fiction!
