[edit] In mathematics

Fifty-three is the 16^th prime number. It is also an Eisenstein prime.

53 written in hexadecimal is 35, that is, the same characters used in the decimal representation, but reversed. Three multiples of 53 share this property: 371 = 173₁₆, 5141 = 1415₁₆, 99481 = 18499₁₆.

But 53 can not be expressed as the sum of any integer and its base 10 digits, making 53 a self number.
