Some Friday afternoon #numberphile to warm your brain up: https://www.youtube.com/watch?v=Jw_ZPdnHGzg

This one's about Very Big Numbers

fractals in reality from Hideki Tsuiki via #numberphile

that h-fractal absolutely has my heart. i want to see it 10 times the size. it's like some weird reality where mathematics is projected into the real world.

Even better when it gets to the “integer dimensioned" fractals.

‪I'm enjoying the free time from classes to finally write a blog post again:

Risky Risk Results - https://mhoehle.github.io/blog/2025/02/21/risk.html

The work was inspired by a #Numberphile episode on erroneous calculations of the probabilities in the Game of Risk.

For anyone interested into how #DUAL_EC_DRBG worked, #numberphile made a good video about it.

Surprisingly low numbers are unresolved in the ways that they're imperfect.

Schönes Video von #Numberphile.

Slightly related habe ich nun einen Knoten im Hirn:

- Pi hat unendlich viele Nachkommastellen, in denen alle überhaupt möglichen Zahlenfolgen vorkommen.

- Also müssen auch *unendlich lange* Folgen sich wiederholender Zahlen, ob 666... oder 123123123..., darin vorkommen.

- Aber dann könnten dahinter nicht mehr alle noch fehlenden möglichen Zahlenfolgen kommen.

#Mathe-Bubble, helft mir mal, wo ist mein Denkfehler?

Got my prime number, 8933.

Nice Numberphile video. Starts with a divisibility test for 7, followed by divisibility tests for the other numbers up to 11.

Just watched an excellent video #TomScott did for #Numberphile about 5 years ago, on #numbers in #language: https://youtu.be/l4bmZ1gRqCc ("58 and other confusing numbers")
Really interesting to see it from a #linguistics POV, and I never realised #base10 was far from the only commonly used base system.

Lovely. How to mathematically determine whether a certain pattern in this classical number toy is possible when the starting pattern is 1,2,3,...,14,15,<blank>. For example, the one shown 15,14,13,...,3,2,1,<blank> is impossible. Ditto for the classic Sam Loyd one where 14 and 15 are switched.
