The FDA has approved the use of these cell lines for the production of these Merck vaccines.. Other common vaccines, including those for chicken pox, hepatitis and rabies, are also propagated in cells originating from legally aborted human fetuses, according to the FDA.erck, the vaccine's manufacturer, acknowledged that those cells were originally obtained from an electively aborted fetus. They were used to start a cell line, which is a cell multiplied over and over again to produce cells that are of a consistent genetic makeup.
Quantum mechanics is the science of the very small. Quantum mechanics explains the behaviour of matter and its interactions with energy on the scale of atoms and subatomic particles. By contrast, classical physics only explains matter and energy on a scale familiar to human experience, including the behaviour of astronomical bodies such as the Moon.
Quantum mechanics gradually arose from Max Planck 's solution in 1900 to the black-body radiation problem (reported 1859) and Albert Einstein 's 1905 paper which offered a quantum-based theory to explain the photoelectric effect (reported 1887). Early quantum theory was significantly reformulated in the mid-1920s.he word quantum derives from the Latin, meaning how great or how much. In quantum mechanics, it refers to a discrete unit assigned to certain physical quantities such as the energy of an atom at rest (see Figure 1).
