Part XXI Water: What Makes it so Unique and so Important
Part XX Water: What Makes it so Unique and so Important “Water, water everywhere and all the boards did shrink, Water, water everywhere, nor any drop to drink” Those words learned so long ago from “The Rime of the Ancient Mariner” by Samuel Coleridge still ring in my ears like the day I memorized them …

Part XX: DNA or Protein; The Great Debate
The story of the true carrier of genetic information from generation to generation is an interesting tale which followed a winding path from the late 1800’s up to 1953 and even that historic discovery, while one of the most sought after and important discoveries of human kind, was really just a new chapter in the …

Part XV: the Milankovich Cycles

The earth is now on the brink of entering another ice age, according to a large and compelling body of evidence that could last for the next …
