That is really cool! I'll pass it along to my ham radio forum.Sorry it was a ppt file and i could not attach it properly
Here it is hope i got it right
You should never teach math to kids. Here's why.That's an interesting take on it.
I watched some of the James Burke series on inventions that changed history. The one on bringing Arabic numerals into Europe was cute:
"How do you write a zero?"
"Just make a hole on the page."
Smart girl!You should never teach math to kids. Here's why.
When my youngest daughter was around 5, she had a plate of cookies. I asked her for a cookie. She gave me a cookie. I told her, "You know I hate odd numbers. I need TWO cookies."
She took my cookie back and said, "Zero is an even number, too!"
Lesson learned.

BBC: 5 NUMBERS The First Series, mentioned above.This thread reminded me of a series of programmes the BBC did on Radio 4 a couple of years back about numbers, looking at some of the most important numbers and their significance in mathematics, science, and nature; including 0, 1, π, e, the golden ratio (~ 1.618), and ∞. If you're in the UK it might be worth a look up (people outside the UK may be able to get the series on the BBC World site).

Ah yes, that was the series. I recall the first series first time around on Radio 4; I don't think I've had a listen to all of series 2. I also got it wrong slightly, 1 isn't in the first series, but i (or j to us EEs) is. Nice to see it is still accessible so I can listen again. I assume you can listen outside of the UK?
And where will it be in another 6 years I wonder?--ETA: Largest Prime Number now known is Mersenne prime, \(2^{43,112,609}-1\), a 12,978,189 digit number
The Second Series (From 2003) states it as \(2^{13,466,917} -1\), 4,053,900 digits long. There were 39 known Mersenne Primes in Oct, 2003, there are now at least 46 known, all since 1996 discovered by GIMPS
That's not bad for a standalone. The biggest problem is an OS that can manage efficiently such power and resources.<SideTrack>
GIMPS at 47 TeraFlops the 5th largest distributed computing supercomputer, similar to folding@home- the fastest "computer" in the world at 8.1 PetaFlops, and SETI@Home 528 TeraFlops. By comparison, the fastest "standalone" Supercomputer as of 11/2008, IBM's Roadrunner is 1.1 Petaflops.
