From JOHN BAEZ
I am the inventor of the ‘Crackpot Index’ described in Feedback (5 December).
While I hope it is not my most profound contribution to science, it may
well be the most practical, so some credit would appear to be in order.
After all, if Beaufort is remembered for his scale of wind speeds, why shouldn’t
I be remembered for my rating of blowhards? Free copies of the Crackpot
Index are available by e-mailing baezucrmath. ucr. edu.
