1. In Memory of JFK November 22, 2013 Aziz S. Inan Donald P. Shiley School of Engineering University of Portland November 22, 2013 1

2. President John Fitzgerald Kennedy (JFK) was born on May 29, 1917 (5-29-1917). While JFK was serving as the 35 th US President, he was assassinated on Friday, November 22, 1963 (11-22- 1963), at age 46. November 22, 2013 2

3. His brother, Robert Francis Kennedy (RFK) was born on November 20, 1925 (11-20-1925). RFK was assassinated on Thursday, June 6, 1968 (6-06-1968), at age 42. November 22, 2013 3

4. This Friday, November 22, 2013, marks the 50 th anniversary of JFK’s death. On this special occasion, I dedicate these next few slides to the memory of JFK. November 22, 2013 4

5. JFK’s birthday can be constructed from three consecutive prime numbers, 17, 19 and 23. How? 5291917 = (23 x 23) 1917 Three Consecutive Primes Lead to JFK’s Birthday November 22, 2013 5

6. JFK’s and RFK’s birthdays have a special numerical connection. How? The reverse of the leftmost four digits of JFK’s birthday equals the rightmost four digits of RFK’s birthday. JFK’s Birthday: 5291917 RFK’s Birthday: 11201925 JFK’s and RFK’s Birthdays Have a Unique Numerical Connection November 22, 2013 6

7. JFK’s Last Name, Kennedy If numbers are assigned to the letters of the English alphabet in alphabetical order (A = 1, B = 2, etc.), the numbers assigned to the letters of “Kennedy” add up to 78. If 78 is split as 7 and 8, the seventh and eighth primes (17 and 19) put side by side yield JFK’s birth year, 1917. 7 + 8 = 3 x 5 where digits 3 and 5 side by side give 35. JFK served as the 35 th US President. 7 + 8 = 9 + 6 where 9 and 6 put side by side make 96, JFK’s age today. 78 = 3 x 26 where 3 and 26 side by side yield 326. JFK got killed on the 326 th day of 1963. 7 + 8 = 15 where 15 th prime number is 47, which equals to the sum of the numbers assigned to JFK’s first name, “John”. November 22, 2013 7

8. JFK’s Birth and Death Dates JFK’s full birthday is 5291917. The sum of the squares of the digits of 5291917 yield 242. Twice 242 equals square of 22 and half of 242 is square of 11. Numbers 11 and 22 put side by side make 1122, representing November 22, the day JFK was assassinated in 1963. The sum of the cubes of the digits of 5291917 yields 1936, which by switching its rightmost two digits, results in 1963, the year JFK was killed. Also, the square root of 1936 is 44, which equals the difference of 19 and 63, which make up 1963. If the digits of 11221963 (the day JFK was shot) are numbered left to right from 1 to 8, the odd-numbered digits put side by side yield 1216, which equals four times 304. Interestingly enough, 304 = 50 + 92 + 91 + 71, where switching the digits of these four two-digit numbers and putting them side by side yield 05291917! November 22, 2013 8

9. JFK’s Birth Year If JFK’s birth year 1917 is split into two numbers consisting of its odd- and even-numbered digits as 11 and 97, these two numbers add up to 108. Coincidentally, the numbers assigned to the letters of JFK’s middle name, “Fitzgerald”, also add up to 108. The numbers assigned to the letters of JFK add up to 27. Multiplying 27 with one less than its reverse (72) yields JFK’s birth year, 1917. November 22, 2013 9

10. JFK’s 46 th Birthday JFK died 177 days after his 46 th birthday, 5291963. The digits of 5291963 add up to 35, signifying JFK’s 35 th US Presidency. 1 + 7 + 7 = 15 = 3 x 5, where again, 3 and 5 side by side make 35. 177 = 3 x 59, where 59 equals the sum of the three consecutive primes (17, 19, and 23) which constitute JFK’s birthday, 5291917. Also, if 177 is split as 1 and 77, 1 + 77 = 78, the sum of the numbers assigned to the letters of JFK’s last name, “Kennedy”. In addition, 46 = 23 + 23, where 23 x 23 = 529, JFK’s birth date, May 29.

11. JFK Died 2 Days After RFK’s 38 th Birthday JFK died on 11221963, 2 days after RFK’s 38 th birthday, 11201963. Ironically, 38 divided by 2 is 19, 38 minus 2 is 36, and 19 and reverse of 36 (63) put side by side yield JFK’s death year, 1963. Also, 38 th prime number is 163 and 2 times 163 yields 326. Coincidentally, 11221963 was the 326 th day of 1963. Also, replacing digit 0 in RFK’s 38 th birthday (11201963) by digit 2 leads to JFK’s death day. RFK died on 6061968, 8 days after JFK’s 51 st birthday, 5291968. The prime factors of RFK’s death year 1968 (2, 3, and 41) add up to 46, JFK’s death age. The prime factors of RFK’s death day 606 are 2, 3 and 101 and 101 – (2 + 3) = 96, JFK’s age today. November 22, 2013 11

12. RFK’s Birth Year Yields JFK’s Birth Date RFK’s birth year is 1925. The prime factors of 1925 are 5, 7, and 11. Interestingly enough, the square of the sum of these primes yield 529, that is, JFK’s birth date, May 29. Note that reverse of 529 equals the rightmost three digits of 1925. November 22, 2013 12

13. JFK is 96 If JFK was alive today, he would have been 96 years old. Twice 96 equals 32 x 6 where 32 and 6 put side by side makes 326. JFK was killed 50 years ago, on the 326 th day of 1963, 11221963. The digits of JFK’s death date, 11221963, add up to 25, which coincidentally equals the sum of the numbers assigned to the letters of JFK’s common name, “Jack”. Also, the sum of the squares of the digits of JFK’s death age, 46, equals 52, which is reverse of 25. November 22, 2013 13
