Here's an odd item. NewScientist.com reports an American engineering student at Michigan State University has discovered the largest prime number ever.
Michael Shafer’s new number is 6,320,430 digits long.
In case you don’t remember, prime numbers are positive integers that can be divided (without a remainder) only by themselves and the number one.
I doubt this number will come in handy any time soon. But its discovery is an achievement rare enough to admire.
