Zero is Hero, A blog by Salah Elleithy

My friend Salah launched a blog a few months ago, Zero is Hero. It can be reached at http://selleithy.blogspot.com/

Zero is a very interesting number. Mankind has been using numbers from the days of the Babylonians. However we never knew about the number zero until much later in history, sometime around 458 AD. Zero comes from arabic term "Sifr" and indicates two very different meanings. The first meaning being empty, and the second a place holder in a larger number to indicate a multiple of ten. Zero did revolutionize the numbering system and provided more meaning to a positional concept of numbers. The positional concept of numbers was introduced around 500 AD by Al-Khawarizmi.

So Salah dropped me a note ... and shared his intriguing blog name ... Take a guess and get a free book on job hunting !!

Something that when it is zero, it leads to prosperity, development and will prevent inflation and depreciation. What is that something? First one to get the correct answer will get a copy of my free book.
