Learn Pi
« on: January 21, 2010, 05:02:17 PM »
Would anyone like to learn it.

Divide it into segments...

3.14 15 926 535 8979 323 8 4626 43 383 279 502 884 19 716 939 93 751 05 82


Always look for palindromes (green)

sets of two numbers that almost repeat.

8979 is almost 89 89

Can you use them to predict the next numbers, or do you have to remember alle the numbers in pi?

It's just to remember, if it was to predict, then I would have a billion digits. Some, say its transcendental. Not sure what that it, but you have to be lucky to find a transcendental number. One mathematician was eating a sandwich (this is true), and he looked at his tomato, and he knew something as simple as a circle couldn't have a never ending nember and he worked out that in the middle of pi there would be a "1001" and it would be a palindrome (because decimals don't count.

I learned it (in 6th grade) this way:
3.14 15 926 535 8979 323 846 26 433 83279 50288 41971 69399 37510

When I recall it, I think of the numbers grouped this way. I worked my way up to 25 digits ...433, then learned the next 25 in groups of 5.

They don't even tell us to learn it. They just say its 3.14. One day I calculated the circumference of my bicycle wheel to the 30th decimal. It was 80 point something....

Just wondering if it was with this pi song when I went to the tune of that it seemed to fall just with your numbers. But, who knows. THat song got me to learn about 15 numbers in about 3 das of listening to it. It's catchy!

I remember reading somewhere that for evening the most challenging engineering problems we don't really need to know pi beyond 20 decimal places. Anything beyond that is generally only useful to mathematicians.

...with this pi song ...

I've heard that before. The pi song is awesome.

I read that to 30 decimal places, you can calculate the circumference of the universe (assuming it is a sphere) to within a millimeter.

We had a contest at my school in 7th grade about memorizing the most digits in pi. There were actually papers taped on the wall through the hallways with the digits  :P

I wish we did that. People couldn't even remember.  :P
