Arithmetical trivia for Bob Moore's 90th birthday
Feb. 15 marked the 90th birthday of Bob Moore, the founder and pioneer of Bob's Red Mill Natural Foods in Milwaukie. Bob is a true visionary in producing high-quality nutritional whole grain foods and the natural food business he founded in 1978 is an Oregon success story that will be an inspiration for generations to come.
I had the opportunity to meet Bob personally at Bob's Red Mill Whole Grain Store in Milwaukie and recognized him to be a humble man who truly cares about others. In his honor, I constructed the following number trivia as a birthday gift for him:
Further, 3 times the product of 2 and 15, the month and day numbers of Bob's birthday, also yields 90.
Moreover, the difference and the sum of 2 and 15 are 13 and 17 respectively and interestingly, 3 times the sum of 13 and 17 equals 90 too.
The product of 13 and 17 equals 221, the reverse of 221 is 122, the 122nd prime number is 673, and 3 times 673 equals 2019.
Additionally, 13 and 17 are the 6th and 7th prime numbers and 6 square plus 7 square equals 85. Note that if numbers 1 to 26 are assigned to the letters of the English alphabet, the numbers assigned to the letters of Bob Moore also add up to 85.
Bob and Moore each contain 3 and 5 letters respectively and note that the difference and the product of 3 and 5 yield 2 and 15, the month and day numbers of Bob's birthday.
Bob's birthday, Feb. 15, is embedded in his first name, Bob, and here is how: If numbers are assigned to the letters of Bob as 2/15/2, the leftmost two numbers 2/15 represent February 15 and the rightmost two numbers 15/2 represent 15 February. (Note that Bob's 73rd birthday in 2002 expressed as 02/15/02 represented the letters of Bob in this form.)
Bob's birthday coincides with the 46th day of each year (2/15) and interestingly, 46 equals the sum of the numbers assigned to the letters of one of Bob's favorite words: Mill.
Furthermore, the sum of the digits of 2/15 equals 8; 8 square is 64, and the reverse of 64 is 46 too. Note also that Bob Moore consists of 8 letters.
Lastly, 64 times 8 is 512 and the reverse of 512 is 215, Bob's birth date, 2/15.
Thank you for your genuine commitment in providing us healthier nutritional food, Bob Moore, and happy 90th birthday!
P.S. Coincidentally, my office number in Donald P. Shiley School of Engineering is 215 representing Bob's birth date, 2/15.
