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??

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

    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.

    Hate to break it to you, but that’s only 69 digits. (Or 68 places). Still a good effort though!
