From the wikipedia article under the subheading *Primality of one*:
"...Derrick Norman Lehmer's list of primes up to 10,006,721,
reprinted as late as 1956,[5] started with 1 as its first prime.[6]
Henri Lebesgue is said to be the last professional mathematician to
call 1 prime.[7]"
Henri died in 1941. Perhaps it takes awhile for the word to get around.

Apparently it hasn't been a prime since wikipedia started. Though what
is a prime is simply a matter of definition as are most mathematical
constructs. (Though some fit the physical world rather well. )
"A '''prime number''', or '''prime''' for short, is a [[natural number]] larger than
1 that has as its only positive [[divisor]]s ([[factors]]) 1 and itself."

"Junior programmers create simple solutions to simple problems. Senior
programmers create complex solutions to complex problems. Great
programmers find simple solutions to complex problems. The code
written by topnotch programmers may appear obvious, once it is
finished, but it is vastly more difficult to create."

According to http://en.wikipedia.org/wiki/Prime_numbers 1 isn't a prime
number any more. Can someone explain (translate) the reason for this shift
in the cosmos?
Where's Henri when you need him? (You have to see the wiki article.)
