The 800th Lifetime

It has been observed that if the last 50,000 years of man's existence were divided into lifetimes of approximately 62 years each, there have been 800 such lifetimes. Of the 800, fully 650 were spent in caves. Only during the last seventy lifetimes has it become possible to communicate effectively from one lifetime to another- as writing made it possible to do. Only during the last six lifetimes did masses of men ever see a printed word. Only during the last four has it been possible to measu...

About 300,000 years after their appearance, matter and energy started to coalesce into complex structures, called atoms, which then combined into molecules. The story of atoms, molecules and their interactions is called chemistry. About 3.8 billion years ago, on a planet called Earth, certain molecules combi...
