75 digits of pi
(Does this count as a podcast?)
When I was a junior geek of 14 or so, some friends and I spent some time filling dead time in a maths class by learning digits of pi. I got to 75. Twenty years later, it’s still hanging about in my brain, wasting valuable brain cells.
Thank goodness it’s knowledge that is useful, rather than some pointless weird-arse geek party trick.

When I was in year 11 maths class, for the same reason, I memorised Pi to 25 decimal places (your 75 puts me to shame). After not thinking about it for 20 years, one day I remembered having memorised it and was able to recall it all correctly. Why is that, when nowadays I can’t even remember my best friends phone number??

I suppose it’d be okay if your friend’s phone number was (03) 1415 9265 …

Um, you actually recalled 76 digits, not 75. Most I’ve ever learned is 400.

I’m in the process of doing it during dull pure maths.. I’m up to 40, i think it is..

I memorized pi to 75 digits in math class. I’m 12 years old.
One day I was so bored i found a cool thing about pi and prime numbers. Here it is:
The 19th through 23rd digits of pi are as follows: 46264
19 is a prime number.
The next 5 prime numbers are 23, 29, 31, 37, and 41.
Find the differences between each prime number:
23-19=4
29-23=6
31-29=2
37-31=6
41-37=4
46264 (see 19th through 23rd digits of pi).

I also like trigonometry. It is fun.
sine cosine tangent cotangent secant cosecant trigonemetric functions.

I made a math website. It’s for 6th through 8th grade. Here it is: Visit My Website
