Remembering Donald P. Shiley: Happy 101st Birthday!

January 22, 2021

Despite being inundated with quote requests by numerous local, national, and international news agencies regarding the remarkable amount of palindrome dates in 2021 (including Inauguration Day on 1-20-21), Shiley School of Engineering professor Aziz Inan constructed the following birthday curiosities to celebrate Donald Pearce Shiley’s 101^st birthday, which occurred on January 19:

Shiley turned 101 this month on 01/19. Interestingly, if 01/19 is split into 01 and 19, the sum of the reverses of these two numbers equals 101.
Further, 101 is the 26^th prime number and twice the sum of 26 and its reverse (62) equals 176, the sum of the letter numbers of Donald Pearce Shiley.
If 2021 is split as 20 and 21, the reverse of the sum of these two numbers equals 14 and 14=1+7+6.
Every year, the sum of the digits of Shiley’s birthday and the sum of the digits of the anniversary day of his death are equal since 1+1+9=7+3+1.
If Shiley’s 101^st birthday, 01/19/2021, is split as 01, 19, and 2021, the prime factors of 2021 are 43 and 47, and interestingly, the difference of the squares of 43 and 47 and the difference of the squares of 01 and 19 are equal.
Lastly, 43+47=90, the age Shiley was when he passed on 7/31/2010.

Happy 101^st birthday, with great respect, admiration, and affection, to Donald Pearce Shiley!
