Many radioactive dating methods are based on minute additions of daughter products to a rock or mineral in which a considerable amount of daughter-type isotopes already exists. These isotopes did not come from radioactive decay in the system but rather formed during the original creation of the elements. In this case, it is a big advantage to present the data in a form in which the abundance of both the parent and daughter isotopes are given with respect to the abundance of the initial background daughter. The incremental additions of the daughter type can then be viewed in proportion to the abundance of parent atoms. In mathematical terms this is achieved as follows. When some daughter atoms are initially present designated D 0 , the total number D is the sum of radiogenic and initial atoms, so that. To establish the condition that both parent and daughter abundances should be relative to the initial background, a stable isotope S of the daughter element can be chosen and divided into all portions of this equation; thus,. This term is called the initial ratio.

Stuck at home during the coronavirus pandemic, with movie theaters closed and no restaurants to dine in, Americans have been spending more of their lives online. But a New York Times analysis of internet usage in the United States from SimilarWeb and Apptopia, two online data providers, reveals that our behaviors shifted, sometimes starkly, as the virus spread and pushed us to our devices for work, play and connecting.

Internet problems arise from the existence of a free and open network that connects most of the world; platform problems arise from features native to the platform. The fact that anti-vaccination zealots can meet online is an internet problem; the fact that Facebook recommended that new mothers join anti-vaccination groups is a platform problem.
