Okay, it's brain relaxing/straining time (depending on your point

of view).

How many places can you remember Pi (or your favorite trancendental {sp?})

to?

Myself, pi to 34 places.

An ex-colegue's colegue, pi to 75 places.

Any advances?

Letsee, all I know is

3.1415926535897932384626433832795028841971693993751058209749445923078

1640628621... (the last 1 is a zero that's rounded up)

That would be 78 places. I know someone who has it memorized 150+

digits, and somebody else who knows it to 400+ (both high school

students). I believe the world record is 40,000.

Everytime I'm really bored, I just start working on a few more

digits. Generally I like to go until I reach a zero, since they make

good stopping places (next time I'm bored, I'll start working on the

next group of digits which is 089986280 (I had to look that part up))

As for other numbers, I know e is 2.718281828459045..., 16 places,

and the next part is 235360 (again, that part I had to look up).

sqrt(pi) is 1.7724538509055, 14 places, and I don't plan to learn any

more.

Those are the only ones I know to more than 10 places, but I'm

working on learning a few digits of logs and square roots of small

numbers.

Ummm ... a little over a hundred, I think. It was a

popular thing in high school.

What I would like to know is whether anyone does this

by picturing or visualizing the digits, as opposed to

reciting them and remembering the sound. I think I read

somewhere that more people do it by sound than sight. But

I'm curious ... if you do it by sight, what does it look

like?

There is a rhyme starting something like:

I know a maths professor.

1 4 1 4 9

He always weeps and sighs,

2 6 5 3 5

whenever polyhedra capsize ...

You get the decimal digits of pi after the decimal point

by counting the letters in the word.

I don't no if its correct, nor how it continues ...

Who does (there might have been something in Sci. American) ??

I learned e to 15 (because of an insane mneumonic device that my high

school teacher showed me) and pi to one hundred because that's how

many I had access to, but I sincerely wonder if it has any worth at

all. It certainly doesn't relax me, and it's hardly something I'm

proud of. Hence, my question is why do so many people find it so

attractive, including those (like myself) who don't particularly enjoy

it?

By the way, I learned pi partially auditory (the first 35), partially

visual (the last 30 or so), and the rest a mish mash of the two.

Needless to say, it's the in-between ones that I know the least well.

Visually just means that I have no auditory association, that is, it

doesn't "sound right," I just see the next five (I memorized them in

groups of five) moving from right to left in front of me.

a guy I knew first year at Univ. of Stockholm knew the first 100, so

I learned 150, then he did 400, so I did 500, then he did a 1000, so

I gave up, but anyways, he remembered them visualy (whereas I did it

by sound,) and he had grouped them on a paper in groups of 5, so it

would make 50 on each line, and then you could ask him "667th decimal"

and he'd find out which line and row, and he'd see that group and tell

you.. he'd do it backwards from the 885th decimal if you wanted him to...

My brother got bored when he was in high school and I think he made

it to about 2000 digits. I'm sure he doesn't still know them and

I think at his best there would usually be a mistake or two in the

last thousand digits.

I should ask him sometime how he remembered them.

I remember 3. 141 5926 535 8 979 323 8 46264 .. and an 8 somewhere

this is how I remember it, I remember the palidromes easiest,

and fill in the gaps, when I was still in high school I think I

remembered about 10 more, but I lost those, I guess not palindromic

enough (3383279502884...)

When I was 14 I had a contest with my brother to see who could memorize

the most digits of Pi (He won with 139). He did it by sound and I did

it by sight.

The interesting thing was that because our list was by groups

of 10 with 5 groups to a line I was able to immediately give, for

example, the 78th digit. My brother had to start with the 50th digit

and go through the series hoping he didn't mess up because he was

counting. Another advantage to having a picture in my head was that I

could recite Pi backwards from the 50th digit. (How's that for

something totally useless :-)

Some time ago I undertook to memorise a hundred or so digits of

pi and wrote an interactive "pi trainer" on the computer. I added

a timer and embarked on a campaign of "speed pi typing" - I used

the top line of digits, not the number key pad. I recorded results

in a "pilog", which I still have. Some notable entries:

50 digits in 7 secs Tue Jan 25 16:46:32 1983

100 digits in 17 secs Tue Feb 15 11:53:14 1983

200 digits in 38 secs Sun Mar 27 16:17:22 1983

300 digits in 57 secs Wed Apr 13 13:44:08 1983

400 digits in 102 secs Fri May 11 16:07:48 1984

I started the timer on the initial keystroke ( "3" )

and ended the timer with a <CR>. The count specifies

digits after the decimal point ( which I also typed. )

I can still do 50 under 15 seconds, but that's about it.

Some have remarked on the visual versus aural methods of

memorizing. I found that I retained the digit sequence as

a motor skill, and actually had to go through the motion

of typing to recall them, in some instances.

I used the popular "groups of five" method throughout.

Not insane!
