I do not get how Python's math.modf works...
Why do I get all the zeros or nines?
4.4 | 4.0 | 0.40000000000000036
4.5 | 4.0 | 0.5
4.6 | 4.0 | 0.5999999999999996
I can fix it with... more math, but maybe I am doing something wrong?

Relaxing at home and got nerd sniped again via YouTube. Looked interesting enough to give it a shot though the thumbnail was more than a bit misleading as they used `n` instead of `x` which has certain connotations associated with it.

Start with the number of your birth month (January is 1, February is 2, and so on), add 9 squared, add 12 minus your birthday month number, multiply the value you have by itself, subtract 2.

Früher hieß es, der Beweis ist trivial oder so. Das ist eine schöne Steigerung. 😉

I am so clueless about math I don’t know what this is called… the thing where you have 3 numbers and can then figure out the fourth value.
This is how I remember doing it in school, and I can calculate it, but cannot remember what it’s called. Also, is there a way to write it out?

Wooo, another nerd snipe:
Find the limit of the xth root of x as x approaches infinity.
Not too horrible, but definitely a smidge of fun.

I've seen 2 people in #Mathematics claim recently that we can't prove that a b=b a - the Commutative Property - and that we just accept it as true. Nope, not only…

Another day, another math problem. Was browsing the Internet and ran across one of those math social media posts that asked to solve `8^x 2^x = 30` and decided to go all the way down the rabbit hole on the solution. Also learned a bit about spacing in math mode for LaTeX as well...

Say you have a machine that spits out hundreds of very long solution attempts to the Riemann hypothesis. Each is tedious and hard and then humans start reading it all until they refute most and finally find one that is correct. It’s a gigantic effort for the humans, but now they have a proof.
Did the machine then _solve_ the Riemann hypothesis?

Pedro the #Math Cat 🐈 is, once again, wondering why it's taking so long to grade these final exams.

My plan to attend #FortWayne #NoKings has been derailed by an unpleasant headcold 🤧 . So I am staying home with Pedro the #Math Cat 🐈

It's #Caturday and Pedro the #Math Cat 🐈 knows these papers should be graded before finals week so he is on top of it.

I have a notational problem to solve. In my linear algebra script polynomials are usually capital letter named, like P,Q ∈ K[t].
Endomorphisms have capital letters from the F,G,H range.
Then in the theory of normal forms we need projection operators, which are endomorphisms, so they ought to be and are currently called P.
But then in that chapter the (characteristic, minimal, ...) polynomials move to small letters which is disturbing.
What should I do?
#math #teaching
Make polynomials small p,q ∈ K[t] throughout
Find a new name for projectors like π.
Don’t change anything, ever!
