All elements above Bismuth in the Periodic Table are unstable, i.e., they are in a constant state of releasing energy, or Each nucleus that alpha decays produces a unique set of alpha-particle energies.As these alpha particles travel through a mineral matrix, they deposit their energy in the mineral itself.
Radiometers generally consist of a glass bulb containing a rarefied gas in which four diamond-shaped paddles are mounted on a central axis.
Each paddle is black on one side and silvery on the other.
Many of us believed that string theory was a very dramatic break with our previous notions of quantum theory.
But now we learn that string theory, well, is not that much of a break.
When radiation such as sunlight strikes them, the black side absorbs radiation and the silvery side reflects it, resulting in a temperature difference between the two sides and causing motion of gas molecules around the edges of the paddles.
This motion of the surrounding gas molecules causes the paddles to spin.— David Gross at 23rd Solvay Conference in December 2005 Radioactive dating is a key concept in determining the age of the earth.Many secular scientists use it to dismantle the faith of Christians and cause them to accept uniformitarian assumptions that, in addition to being scientifically erroneous, demand a figurative and distorted interpretation of Genesis.The object's approximate age can then be figured out using the known rate of decay of the isotope.For organic materials, the comparison is between the current ratio of a radioactive isotope to a stable isotope of the same element and the known ratio of the two isotopes in living organisms.Radiocarbon dating is one such type of radiometric dating.
