Libby radiocarbon dating

Signals from radioactive decay can then, e.g., show the path taken by the stable element through the human body.

This idea worked out and gave George de Hevesy the 1943 Nobel Prize in Chemistry.

In 1940 he married Leonor Hickey, by whom he had twin daughters.

In 1966 he was divorced and married Leona Woods Marshall, a staff member at the RAND Corporation of Santa Monica, Calif.

Protons and neutrons make up the center (nucleus) of the atom, and electrons form shells around the nucleus.

The number of protons in the nucleus of an atom determines the element.

I can get much of the gist without delving into the deepest details or formulas. In fact after you get through the intro on radioactive waves from outerspace soaking into our bodies and slowly decaying over 5730 years you will realize there are some serious mathematical flaws.

It is quite dated, I suspect, but fascinating for being in the author's scientist voice. Sorry frequent fliers, you will age like crazy since they accumulate at the same altitude commercial jets fly.

To prove the survivability of nuclear war, Libby built a fallout shelter at his house, an event that was widely publicized.The first 75 pages are the text that explains how C14 is formed, the assumptions made about its behavior in the atmosphere and in living tissue, how it was prepared and analyzed, etc. I still eagerly await that book, apparently yet to be written. The equation does not work in the short term or less than 5000 years or in the long term or over 40,000 to 50,000 years.The remainder of the book is a list of objects that at that time (1955) had been dated using his techniques. The author also does not find items in nature to develop the formula but first has the formula and then seeks out things in nature that add up to the numbers that work in his formula. I first heard this story told by the geologist Cesare Emiliani, who described Libby as perhaps the last scientist to make a major contribution to science nearly single-handedly. He did this largely on his own over a period of many years, many trials and tribulations.
