The 20th Centuary's Greatest Idea

[Argonavis]

The most astounding advance to emerge from the 19th C was the Darwinin Wallace theory of Organic Evolution.

The most powerful idea to emerge from the 20th was the concept of physical evolution - that the elements are transformed through nucleosynthesis and we are composed of billion year old carbon.

I understood the seminal paper was written in the late 1950's, by Burbidge, Burbidge, Hoyle, Fowler which defined the mechanism by which stars produce the heavy elements.

Another contributor to the science of this gradual realisation of physical evolution was Hans Bethe (1906—2005)

for a shockingly good read on this, I recommend Ken Croswell's "The Alchemy of the Heavens". His web site is well worth a visit as well. He has put many of his articles online.

My great admiration goes to people like Hans .... Answering the really big questions of... how ?
The questions that we can all spend our lives pondering though are ...why ?
Why are we here now, with the insight & intellect to ask these questions ?
