But there are some questions that come to mind: Calculus students typically meet this problem somewhere in the second semester.

It is one of the simplest examples of a differential equation.

In other words there was originally 4 parts per million Parentium-123 and 0 parts per million Daughterium-123.

Since there is now only 1/4 of the original amount of Parentium-123, we know that two half-lives of Parentium-123 have elapsed.

Using fossils as guides, they began to piece together a crude history of Earth, but it was an imperfect history.

After all, the ever-changing Earth rarely left a complete geological record.

The energies involved are so large, and the nucleus is so small that physical conditions in the Earth (i.e. The rate of decay or rate of change of the number N of particles is proportional to the number present at any time, i.e.

Another isotope, carbon-14, is useful in studying abnormalities of metabolism that underlie diabetes, gout, anemia, and acromegaly.

...prehistoric archaeology occurred in 1948, when Willard F.

Libby, at the University of Chicago, developed the process of radioactive carbon dating.

A photosynthesizing plant does not strongly discriminate between the most abundant natural carbon isotope ( The discovery of natural carbon-14 by American chemist Willard Libby of the United States began with his recognition that a process that had produced radiocarbon in the laboratory was also going on in Earth’s upper atmosphere—namely, the bombardment of nitrogen by free neutrons.

Newly created carbon-14 atoms were presumed to react with atmospheric oxygen to form carbon dioxide...
