Sample text

For Einstein to be able to see that energy and mass are two sides of the same coin and to then use math to express this fact, and then do it in such a simple form is an intellectual marvel and the likely reason why you have heard of it before. Energy : Mass :: Yin : Yang 58 CH 28: Quipu to Mathematica Perhaps an effective method to assess the level of scientific sophistication in a society is to examine the tools they use for mathematics. Many ancient civilizations considered the abacus landmark in allowing people to calculate quickly.

They wrestled with the philosophical idea that nothing could be something, and these became deep religious questions, even many centuries later. In 9th century India we see the first practical use of the number zero, in that it was treated as any other number. Even the ancient Chinese, a civilization rich with sophistication, took until the 13th century to develop an actual symbol for zero. It is rather easy in our modern society to take for granted the simplicity and necessity of the zero but for much of human civilization; it has been a complex quandary without an obvious solution.

In the digital domain however, that randomness is a bit harder to emulate. In fact, it is so difficult that there is a term called a pseudorandom number, which refers to a number that appears to be random but is in fact not. In cryptography, which is all about how to protect information, it is dangerous to use pseudo-random numbers to protect your data. Since there is a deterministic process to arriving at a pseudorandom number, generally an algorithm, that process can be uncovered and therefore the information stolen.
