In these cases, the wavefunctions of the system in question are represented as vectors, the components of which correspond to coefficients in a linear combination of the basis functions in the basis set used. The operators are then represented as matrices, (rank two tensors), in this finite basis.

History of U.S. Unemployment. The U.S. government began tracking unemployment officially in the 1950s, but estimates of previous unemployment rates are not difficult to ascertain. The Great Depression of the early 1930s had an unemployment rate of 23.6 percent â the highest in modern times. The countryâs lowest rate â 1.2 percent â came in 1944 when millions of men were in uniform and the wartime (World War II) economy was in overdrive. The lowest post-war rate was 2.9 percent in 1953.
