Abstract
A palindrome is a word or phrase that reads the same forward and backward, such as the word “level” and the phrase “Madam, I’m Adam.” Numbers whose digits read the same forward and backward are also called palindromes, such as the numbers 22, 1234321, and 2002. Palindromic phrases can also occur in number form, for example the Universal day of Symmetry: 8:02 P.M. on February 20, 2002. If one were to look at the time on a twenty-four hour clock, it would read 20:02; the date can be read as the twentieth day of the second month, which also represents a 2002. Of course, the year is already a 2002. Putting the whole date together gives 2002 2002 2002, a palindromic number phrase. The word palindrome comes from the Greek word palindromes, meaning “running back again”.
