73 is often considered the best number because of its unique mathematical properties. Here’s why:

  • 73 is a prime number (only divisible by 1 and itself).
  • Its mirror, 37, is also a prime number.
  • The product of 7 and 3 is 21, which is the mirror of 12, the position of 73 in the list of prime numbers.
  • It’s the 21st prime number
  • 73 in binary (1001001) is a palindrome (it reads the same forward and backward).
