Rutherford and holmes radiometric dating
Once this energy was discovered a new, successful strategy called radiometric dating would be developed.
Today radiometric dating places absolute dates on the relative time scale.
The interest in Rontgen’s discovery would launch the second scientific revolution; the first being launched by the work of Galileo (Asimov, 1984, pp 514-515).
By 1904 physicist Ernest Rutherford showed how this decay process could act as a clock for dating old rocks.
From the fragments, scientists calculated the relative abundances of elements that formed as radioactive uranium decayed over billions of years."It was not until the 1950s that the age of the universe was finally revised and put safely beyond the age of the Earth, which had at last reached its true age of 4.56 billion years," Lewis said.
"Physicists suddenly gained a new respect for geologists."For the record, the universe is now thought to have debuted, at least in its latest incarnation, about 13.7 billion ago.
To his surprise the compound could do this even when it was not fluorescing.
This energy did not only have penetrating power it also ionized the air as shown by an electroscope.
