RE: prime number challenge
I was thinking more of the folks that can look at a photo of pebbles or some such, and more or less instantly give an accurate total of how many there are.

So would it even be possible theoretically for a person to look at a 10 digit number and ascertain in a few seconds whether or not it's prime ??
