Pi Memorization!

Post Reply New Topic

3.14 has always worked well enough for me.

42 places. Because that is the number of digits needed to calculate the circumference of any circle in the observable universe to the accuracy of the diameter of a proton. I may bother to learn more, but any more digits is useless until the observable universe gets bigger.

100.

Writing my own computer algorithm to compute the digits sounds more fun to me.

I found this old thread...

Ten years ago I was into memorizing digits of Pi. I read an article about a man who had memorized over 10 000 digits and wanted to try, how many I would be able to learn (I don't usually remember numbers well). I got somewhere around 600 digits, but then I lost interest. I deciced to test myself yesterday, and I could only remember 22 digits. I think I'll give the memorizing another try now, then years later, just for fun. I'll not probably even try to get to 600 digits this time.

How I want a drink, alcoholic of course, after the heavy lectures involving quantum mechanics. And if the lectures were boring or tiring, then any odd thinking was on quartic equations again,

(see http://mathworld.wolfram.com/PiWordplay.html)

I'm memorising pi in hexadecimal. I've got to 112 digits.

What's the world record?

I memorized 100 digits. That was an artistic endeavor for me. Basically, I learned the Dominic system and Journey of Loci. Then I made up a story about characters doing different stuff along a path of a place I used to work at. It was a good way to build creative muscles.

Personally, it still bothers me that I don't yet know much about pi itself beyond it being the ratio of circumference to diameter. I imagine pi having to do with n-gons with each side being the same length. Then I imagine that for a perfect circle, that's got to be a huge number of sides. Then I realize that those sides have to each be tiny to the point of approaching near zero.

Then I just find myself feeling confused and realizing I know virtually nothing. Oddly enough, this sort of confusion makes me "happy". It reminds me that there's an interesting world out there.

Apu: I can recite pi to 40,000 places. The last digit is 1.
Homer: Mmmm...pie.

I don't see the point of knowing it past about 4 or 5 decimal places, in reality you can only be so precise in practice like when you take in consideration of the margin of error of machining equipment as an example. It is impressive that people can memorize it to so many decimal places though, I am just glad that if I found myself transported back to 1996/1st grade I could unlock my bike because I still remember the 5 digit code.

1000 decimal places, but I only did it for less than a day. Might do some more soon.

Daniel Tammet has memorized Pi to more than 22,500 digits.

I can't remember my phone number.
