Maths Around the Clock (2018)
- OisinMoran 6y agoThis is a great link! If you enjoy weird clocks here's a vague clock I made: https://oisinmoran.com/clock.html https://oisinmoran.com/clock.html More closely related to this I also wanted to make one of these style of clocks from the article using just a single 4 along with the square root, factorial, and floor operations (from Knuth) although so far I haven't been able to get 9 or 12. I haven't worked on it in ages but you can play with the live calculations here, nicely typeset in KaTeX: https://oisinmoran.com/projects/root_floor_fact_four.html https://oisinmoran.com/projects/root_floor_fact_four.html

- maps7 6y agoYeah, I should have put a space between the link and "[1]" EDIT: The "[1]" should have been at the start too!
