CDIAC has updated its presentation of data from the NASA Goddard Institute for Space Studies Surface Temperature Analysis (GISTEMP), which finds that 2015 was by far the warmest year in the modern temperature record.

Rutherford applied the principle of a radioactive element's half-life to studies of age determination of rocks by measuring the decay period of radium to lead-206.

Half-life is constant over the lifetime of an exponentially decaying quantity, and it is a characteristic unit for the exponential decay equation.
