If you take any real number and repeatedly applying the cosine to it, the result always converges to the same constant (0.73908...). This problem shows that the convergence is fast enough that the differences add up to some differentiable function. #calculus #Math pic.twitter.com/8scsuWldTV

Want to try this again - please RT for reach:
Alice is looking at Bob. Bob is looking at Chris. Alice is standing. Chris is not standing.
Question: Is someone who is standing looking at someone who is not standing?

The answer will follow :P curious how people approach this.

Some abstract theorems can be used as tools to simplify matrices to practical ends. Here is an example utilizing the beautiful result on the polynomial algebra K[x] being a PID (principal ideal domain) for any field K - leading to the Jordan canonical form. #algebra #math pic.twitter.com/V8nxn8nzh5

Basic Abstract Algebra: Groups

So, last we left off we discussed sets and monoids. Monoids will be our jumping off point in discussing groups! So, a group is a set with a binary operation that is associative and unital, as monoids are. (1/12)

Re-sharing as #DisruptJMM fades & #DisruptMath emerges!

Direct link to #DisruptMaths presentation [#TMCNYC19]:

Hoping the mathematical `Disruption` cuts across pre-K to 12 as well as post-secondary and other mathematical spaces.

Veterans with traumatic brain injuries (TBIs) can have constant pain & reduced cognitive function. I wrote the law to improve care for service members with TBIs & am disgusted the president would trivialize these severe injuries. Our troops deserve better. https://t.co/dWTdZHtGHQ

Entropy is the amount of information you don't have about the random details of a system: what you'd need to describe those details.

It takes 500 zettabytes to fully describe a gram of liquid water, but a manageable amount per molecule!

I know, *everyone* is hiring for machine learning these days. It is OK if you like this, but if you still love (like me) (a) good old fashioned computational integer linear programming and (b) teaching, write me an email; we are hiring PhDs/postdocs @OR_RWTH #orms

A mixture of Gaussians model can be represented as a weighted points cloud (actually a measure) over the mean/covariance domain. Mixture fitting is a non-convex optimization problem. https://t.co/zuaAu2GwcR pic.twitter.com/PFAesnpfko

Tiling a 16x16 board, with one unit removed, using L shaped tiles. Recursively divide into four smaller boards, place the tile on those not containing the omitted square. This reduces to four smaller instances of the problem. Works with any square board of size 2^n. pic.twitter.com/jyUmJtLlzH
