Finding pi in a needle-stack

preview_player
Показать описание
Start with a floor with parallel lines that are equally spaced out and randomly throw some needles on to this floor. It seems like one divided by the probability (of a needle crossing a line) is approaching pi. This may seem like a coincidence, but it is a legitimate way to approximate pi using probability, called Buffon’s needle.

#buffon #needle #pi

very nice video, easy to follow for the layman, and those with some math knowledge can enjoy this too as you kept is brief and reasonably assume we know what, for example, an integral is. perhaps you can speak a bit stronger, but that is just something all small/new YouTubers face, and a better mic/more videos will improve that sole issue. Good job.
