[HCARC] 73

[W4wj at aol.com]

Of course 73 is our amateur radio
shortcut for 'Best Wishes'

For  those of you nerds who watch The Big Bang Theory
Sheldon occasionally wears a  tee with 73 on it. Not
for ham radio but for:

"The best number is  73.... 73 is the twenty-first prime number. 
Its mirror, 37, is the twelfth  and its mirror, 21, is the product of 
multiplying (hang on to your hats) 7  and 3.... In binary, 
73 is a palindrome: 1-0-0-1-0-0-1, which backwards is  1-0-0-1-0-0-1."

73, something we have used for years because we also  
knew it was 'The Best Number'.....
