Really BIG numbers...

I remember the late Carl Sagan saying that if you tried to write out a Googleplex in standard notation, the amount of paper required would not fit in to the visible universe.

How the "Graham's" number compares to this I'm not sure.

PS. I downloaded 'Horizon' earlier today. They're discussing Infinity. Whether it's worth watching (or even whether it's watchable at all) I won't know until later.

Anyone interested in numbers, especially prime ones, should read this book about Paul Erdos, see .
It is a wonderful book. It must be great, and lonely, to be brilliant.

Wikipedia says the last 10 digits of Graham's Number are 2464195387. I have not independently verified this. Lately.

Horizon is a great way to make one look clever.

The last digit of Grahams' number is indeed 7.

How round can a circle be?

My brain hurts now.

There's an Infinite number of infinite worlds.

Here was I thinking the answer was 42.

It's also a great way to make you feel really stupid, as well.

Yes..sigh. It is

LOL. I wanted to say that.

Hi guys
Rather than spend your afternoon worrying about whether we are dumbing down, or whether Munch was wrong to have the audacity to mention the weather, do something really useful.

Download this little programme and calculate pi on your own computer. 10,000 places done is a trice. You can work out the circumference of your turntable platter impressively accurately now.

Will it tell me why some so called 12" LPs have a larger radius than others?

If some have problems with number ones and number twos, how will they ever manage a gooleplex?

Ya, the stupefying size of unreasonable numbers was why I was watching leaves blowing in the air outside the classroom.

Don - the one I put a link to above in 'how round can a circle be?' sort of makes 10k look like nearly nothing..

''A computer scientist claims to have computed the mathematical constant pi to nearly 2.7 trillion digits, some 123 billion more than the previous record''.

Still not exactly as big as a Grahams I admit, but accurate enough for an Lp12.

'Can we get behind numbers to find what it is they measure? Can we come to grips with numbers themselves what they are and where they came from'?

And:

'All of this makes infinity a fascinating, elusive topic. It can be like a deer, spotted in the depths of a thick wood. You will catch a glimpse of the beauty that stops you in your tracks, but moments later you are not sure if you saw anything at all. … We may then open up clear views on this most remarkable of mathematical creatures – a concept that goes far beyond sheer numbers, forcing us to question our understanding of reality'.

I very much doubt you would understand it. Do you have an interest in maths btw?

Must have been a headache, fitting all that onto the front cover.

The book is called "How to get small-minded men to post on the Internet."

Worked on me.

Mike,

You're being too hard on yourself! I'm sure nobody here would describe you as "small minded".

Mongo, Mike D

My apologies for any offense you may have taken from my comment above.

What fascinated me was the way in which you can get a room at the Infinity Hotel, even if every room was taken - just by getting everyone to move to the room next door.

I have already answered this question elsewhere. Try to keep up.
