People memorize pi, but what about the square root of 2?
2006-10-10 7:06 pm
I know these dudes in Japan can memorize over 100,000 digits of pi, (the one currently on erecord is 52,000 or something) and I was wondering, what about the square root of 2? Or e? People haven't memorized those yet. I want to memorize something; pi, square root of 2, e, etc., but I don't know which one. Yes, I'm a geek, I have no life, but I need to know. I might do the square root of 2, because no one has set a record for that yet. What do you people think?

Once I was bored, with a calculator in hand OH NO!, and I memorized the square roots of 2, 3, 5, 6, 7, 8, and 10 all to 10 decimal places.
Does that mean I'm a bigger geek than you?

I have memorized the sq.rt. of 4 to 50 places. Is that a record?

I recommend memorizing prime numbers; this is something Gauss did, and led him to formulate the prime number theorem. Can you memorize up to 541 (the 100th prime)? This will help you get good at arithmetic too. Memorizing irrational numbers to base 10 is much less valuable.

Being a geek is no excuse for spending your energy on something so useless. How about studying some decent math instead?

Maybe instead of memorizing an irrational number, you could memorize a meaningful series of numbers. For example, the squares of the integers:
1,4,9,16,25,36, etc.
Or perhaps the powers of 2:
2,4,8,16,32,64, etc.
Memorizing these may help you solve some equations very rapidly.

Strictly speaking you can't memorize either because they go on forever.

Yes,
when i was in school it was normal to memorise the square root of 2, 3 and 5.
If you use triginometry, it is useful to know square root of 2, 3 in particular.

pi is used because it is the first irrational number people encounter, and therefore it is the most famous. If you think about it, most people learn about pi in elementary geometry, when they learn the basic formulas for the area and circumference of a circle. This is at least a year or two before learning about square roots (besides, sqrt(2) doesn't have a Greek letter assigned to it) and at least a few years before people learn about the Euler constant, if they even learn about it.

JUz becoz U wanna do something like this doesnt mean U're a geek. I think thats cool. Go for it n good luck!!
