Many moons ago, I had a colleague named Ada, who I called my favorite “palindrome.” Ada was a delight to work with and knew precisely what it meant, so she gave me a novel to read called “Palindrome” that she thought I might like. For those who may not know, a palindrome is a word that has the same spelling backwards and forwards.*
The most famous English palindrome is “Madam I’m Adam” which can be read forward or backwards sans the punctuation. Yet, many names are good palindromes. Ada, Anna, Elle, Eve, Hannah, Sis, e.g. fit the bill. And, Mom and Dad are the most popular palindromes. The most recent numerical palindrome is the year 2002, but we had one eleven years before in 1991. Before then, we would need to go back to 1881.
Yet, palindromes can also refer to identical twins. They are as close to mirror images as we can get in nature. Not to spoil the novel by this name, but identical twins factor into the storyline.
I bring this up as my wife and I have a new favorite palindrome. Ada will have to step aside as the old favorite, as we have a new niece named Hannah. Hannah is a great name to begin with, but the fact it is a palindrome makes it even more worthwhile. Welcome to the world Hannah. I know your parents are glad you were not identical twins
*A palindromic number (also known as a numeral palindrome or a numeric palindrome) is a number (such as 16461) that remains the same when its digits are reversed. In other words, it has reflectional symmetry across a vertical axis. The term palindromic is derived from palindrome, which refers to a word (such as rotor or racecar) whose spelling is unchanged when its letters are reversed. The first 30 palindromic numbers (in decimal) are:0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 22, 33, 44, 55, 66, 77, 88, 99, 101, 111, 121, 131, 141, 151, 161, 171, 181, 191, 202, … (sequence A002113 in the OEIS).
