Triumph of the Nerds

This film chronicles the rise of the personal computer/home computer beginning in the 1970s with the Altair 8800, Apple II and VisiCalc. It continues through the IBM PC and Apple Macintosh revolution through the 1980s and the mid 1990s at the beginning of the Dot-com boom. It includes interviews with Apple Computer's Steve Jobs and Microsoft's Bill Gates. This three-part film first premiered on PBS in June 1996. http://www.youtube.com/p/4D5CD637F73C24C7&hl=en&fs=1

Publishing equations without images

Fibonacci number is the sum of the two previous ones, yielding the sequence.

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, ... .

Fibonacci numbers are related to the golden ratio ? and to its conjugate , which are given by the following

phi  = [1 + sqrt{5}]/2 = 1.61803

 

bar{phi}   = [1 + sqrt{5}]/2 = -0.61803

F_{i}  = (phi -bar{phi}) / sqrt{5}

Fibonacci numbers are related to the golden ratio Φ and to its conjugate , which are given by the following

\phi  = [1 + \sqrt{5}]/2 = 1.61803

 

\bar{\phi}   = [1 + \sqrt{5}]/2 = -0.61803

F_{i}  = (\phi -\bar{\phi}) / \sqrt{5}
