Historical Note on Sheldon Prime
The name Sheldon prime was named for the fictional physicist Sheldon Cooper, who expounded upon the properties of the number $73$ in (fittingly) episode $73$ of The Big Bang Theory, by Lee Aronsohn, Jim Reynolds and Maria Ferrari:
- $73$ is the best number:
- $73$ is the $21$st prime number.
- Its mirror $37$ is the $12$th prime number.
- Its mirror $21$ is the product of multiplying, hang on to your hats, $7$ by $3$.
- Eh? Eh? Did I lie?
- We get it. $73$ is the Chuck Norris of numbers.
- Chuck Norris wishes.
- In binary, $73$ is a palindrome: $1,001,001$, which backwards is $1,001,001$, exactly the same.
- All Chuck Norris backwards gets you is Sirron Kcuhc!
