1 In Memory of Nelson Rolihlahla Mandela 5 December 2013 Aziz S. Inan Donald P. Shiley School of Engineering University of Portland 5 December

2 South African anti-apartheid revolutionary and President Nelson Rolihlahla Mandela was born on 18 July 1918 ( ). We lost this great man today, on 5 December 2013 ( ), at age December

3 I dedicate these next few slides in his memory. 5 December

4 Mandela’s death date, 5 December, expressed as 5-12, or simply as 512, is the highest-power date in each year. How? 512 = 2 9 ! Mandela died on the Highest- Power Day of the Year 5 December (Note that 5 December (512) is the highest-power date of each year in the day-month-year date format. However, in the month-day-year date format, the highest-power date is October 24, expressed as 1024 = 2 10 !)

5 Mandela died on a Pythagorean Day. Why? If 5 December 2013 is expressed as , then: = 13 2 ! Mandela died on a Pythagorean Day 5 December Other such ascending-order Pythagorean Days in each century in day-month-year date format are , , and (Additional Pythagorean Days in the month-day-year date format are , , , and )

6 If numbers are assigned to the letters of Mandela’s full name based on the English alphabet (let A = 1, B = 2, etc.), number 512 (representing Mandela’s death day) repeats in his full name three times: NELSON  ROLIHLAHLA  MANDELA  Number 512 Repeats in Mandela’s Name Three Times 5 December

7 Number 121 repeats four times in Mandela’s full name: NELSON  ROLIHLAHLA  MANDELA  Number 121 Repeats in Mandela’s Name Four Times 5 December

8 How? 121 = 11 x 11 = = 484 = 22 x = x 44 = 11 2 x x 43 = = ! Four 121’s “Magically” Lead to Mandela’s Death Date 5 December

9 Mandela’s death date, 5 December 2013, can be written as: Numerical Connection Between Mandela’s Name and Death Date 5 December Notice that numbers 523 and 11 are intertwined to result in Interestingly enough, reverse of one less than 523 is 225, which equals the sum of the numbers assigned to the letters of Nelson Rolihlahla Mandela [1]. Also, interestingly, 523 – 11 = 512 (again, 5 December).
