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.
In physics, classical mechanics, also known as Newtonian mechanics, is one of two major sub-fields of mechanics developed principally by Isaac Newton and Gottfried Wilhelm Leibniz. The other sub-field is quantum mechanics. Classical mechanics is concerned with the set of physical laws describing the motion of bodies under the influence of a system of forces. The study of the motion of bodies is an ancient one, making classical mechanics one of the oldest and largest subjects in science, engineer
