Professor Comes Up With a Way to Divide by Zero

54mc writes "The BBC reports that Dr. James Anderson, of the University of Reading, has finally conquered the problem of dividing by zero. His new number, which he calls "nullity" solves the 1200 year old problem that niether Newton nor Pythagoras could solve, the problem of zero to the zero power. Story features video (Real Player only) of Dr. Anderson explaining the "simple" concept."

      My £100 (equivalent $200) will happily divide by Zero. It displays and "E" on the screen which I take to mean 14 in hex. So anything divided by Zero is 14. Apart from Zero divided by Zero which amusingly it consider to be Zero.

      In fact, using proof-by-blatant-assertion,

      if 0/0=14
      then 0*14 must = 0
