Those long winter evenings must just fly by in the Haraguchi household! Can you imagine him at a party....."Hey Akira, got any good party tricks?" "Oh man, you just had to ask him didn't you!"

:D :D :D !!!

At this rate I will cut it at 3.15!! :p

Flames to Akira!!! :eek:

e better than Pi!!! ;)
 
I find when learning lines, etc... i don't think about it... things just become long strings in my head and my mouth does the repeating not my brain if you get me.

When learning german oral presentations for school I used to learn like the first paragraph one night then the second an hour later and the third after an hour break again, etc etc. then i'd be able to recite the whole thing without thinking.

And even now, 4 months later, if someone mentions the first word of the whole thing (which i have forgotten now) it'll all come back to me.

SO... if this guy learnt like this.. perhaps its possible. Just over 5000 seems impossible to me!... oh well he's obviously running embedded OS X.

At the risk of showing my age, when I got my first Guinness Book of Records, the record for memorizing pi stood at just over 3000. There was a photo of it written on a blackboard.
 
I have to say, this is one of the most amazing feats I've ever heard of a human performing. I routinely hear about people doing things that really impress me, but this is a whole different level. It boggles the mind.

Now WHY he did it is another issue entirely...

Actually, wasn't it the Japanese who were thinking of shortening the use of pi to just 3 for math in school?

There was a bill passed by some state house(Missouri iirc) to that effect. It was one of the innumerable junk bills that get passed by voice vote for recognition. They make big stacks of them on they get announced but not read and passed by voice vote with perhaps a couple of half hearted nays because everybody wants to recognize granny Farnsworth for being a good great grandmother and making the best peach cobbler in East Bumblefark. And to acknowledge the 30 odd eagle scouts and girls with the silver award(I think that the GS equivalent)

I know about 12 digits of pie. I was in a room once with 12 people who knew it out to 100 and 3 who could take it past 150. We were there for other reasons but had a mass pi recitation.

There was something else I was going to add but can't remember.

To all the people who think its irrelevant to know that many numbers of pi, it can be usefull once you know that pi sequence is totaly random.

Actually, in old statistic books, the last few pages were filled with the pi number and could be used to pick any random number.

Btw, dont ever think about renting the PI movie. It really sucks and has no logic at all...

Is there an equation to derive the value of pi? if there is, could that old man use the equation to come up with the numbers mentally (even that is a feat by its own).

PS: Sorry if I am asking an obvious question, I kinda forget what I had learnt about pi for a long time.

I used to love Magnum PI!

"How I wish I could remember pi" That's always stuck with me from school and served me well the few times I've actually need to use pi in real life.

I can't understand how Mr. Haraguchi can remember a stream of digits that long.
I'm lucky I can remember "83,431."

I have a good memory for numbers, as I can remember many phone numbers, passcodes, locker combinations (including my padlock that I've had for about 15 years and use about 3 times a year), etc. So I guess I can remember many short numbers, but no long ones.

Pi is just the ratio of the circumference of a circle to it's diameter. As far as I know, there's no equation that would allow him to do this.

Just think of it as bob's phone number, janes bust size, how old you were when you first kissed a girl, the number of people who were supposedly deep throat, the number of times you've seen deep throat... etc.

Yes, but its very inefficient. You need to solve 3 or 4 polynomials for each new digit (and keep track of all of the decimal places).

What I would like to see is someone measure pi to confirm the euclidian nature of the universe.

That's what I was thinking also, but check out this link. If he was using one of these methods, that may be even more impressive then memorization!
 
I've impressed the service man at the acura dealership by reciting my VIN (Vehicle Identification Number) to the guy before my 25,000 mile service. My friends think I'm nuts for knowing that number! But it's only 26 digits.. that's .0031163 of the 83,431...
 
Another way to look at it - if he recited those digits at a rate of approximately Pi digits per second, he would have been reciting numbers for 7.3769200317222 hours.

If he could have made it to 4 digits per second, he'd still have been up there for nearly 6 hours. I wonder if he got bathroom/food/water breaks? :eek:
 
Anyone want to recite pi backwards? Even if you only know one digit's worth, I'll be impressed!
