Are there any SpongeBob SquarePants experts here?

I would like to know from which episode are these images coming: https://vimeo.com/27806741.

It illustrates the "man in the middle" attack, a well-known attack in #cryptography.

Because this game will never be played enough (in my opinion), here is the trailer for Hollow Knight, my favorite game!

An "Egyptian fraction representation" [1] of a rational a/n ∈ ℚ is a solution in positive integers m₁, m₂, ..., mₖ∈ ℕ to the equation

a/n = 1/m₁ + 1/m₂ + ... + 1/mₖ

Example: 5/6 = 1/2 + 1/3

Hi, I'm new here and I did not know here had a math community and I decided to join. I hope to share with all of you and learn new things from you. I speak Spanish and English. At this moment I study by my own mathematics. I love learning new things that I don't know. Nice to meet you, guys.

I've been on Mastodon for a time. That's the reason I created an account here to sharing mathematics topics with all of you. :)

I am a big fan of the anime and manga #OnePunchMan, but until recently I did not read the webcomic, mainly because of the art.

Well, that was an error, this is way too hilarious.

Though I will never take a notes with anything except paper and pencil, this is a great LaTeX figure tutorial, and now I'm playing with Inkscape

I did not find any capitalist prime ≤ 10⁴ 😄, using the following code in SageMath Show more

I often see people use #Doodle to organize polls but did you know https://framadate.org by @Framasoft ?

So now I think I'll try to find "capitalist" primes: that I define as follow.

A capitalist prime is a prime number p > 5 such that at least 50% of the values 2!, 3!, ..., (p-1)! belong to at most 1% of the classes modulo p.

A socialist prime [1] is a prime number p > 5 such that 2!, 3!, ..., (p-1)! are all distinct modulo p.

It is called "socialist" because the values are equally distributed among the classes 🙃

A friend told me that

n! ≤ nⁿ

was the only thing he could say about how fast factorials grow. Well, he's not that far, because we have Stirling's formula [1]:

n! ≈ nⁿ · e⁻ⁿ · √(2πn)
