In particular, the energy of a photon equals Planck's constant times the frequency of the radiation. Mathematically, this is given by the equation E = hf. Planck's constant is the fundamental constant of quantum theory that determines the scale of the small-scale world.lanck's constant = 6.63 * 10^-34 joule-second (J-s). The total energy in an electromagnetic wave is the sum of the energies of each photon in the wave. The energy of a photon is so small that we usually measure it in electronvolts (eV). One eV is the potential energy of each electron in a 1-volt battery.
A social revolution inevitably encounters an obstacle in the form of the political power of the ruling class. Hence, the first act of a social revolution is political revolution, the attainment of state power by the revolutionary class.
During the Social Security program's start-up period between January 1937 and December 1939, the SSA only made one-time, lump-sum payments. According to SSA historians, Ernest Ackerman was the first recipient of Social Security benefits -- 17 cents, paid to him in January 1937. The first person to receive monthly benefits was Ida May Fuller from Vermont, who retired in November 1939 and started collecting benefits in January 1940 at age 65. In the three years that Fuller worked under the program, she contributed a total of $24.75.
