Moment of inertia, in physics, quantitative measure of the rotational inertia of a body—i.e., the opposition that the body exhibits to having its speed of rotation about an axis altered by the application of a torque (turning force). The axis may be int
Atomic mass unit (AMU), in physics and chemistry, a unit for expressing masses of atoms, molecules, or subatomic particles. An atomic mass unit is equal to 1 12 the mass of a single atom of carbon-12, the most abundant isotope of carbon, or 1.660538921
He developed the general theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics). He is best known in popular culture for his mass–energy equivalence formula E = mc2 (which has been dubbed "the world's most famous equation"). He received the 1921 ...
Its explanatory importance is comparable to categories such as evolution in biology, gravity in physics, and disease in medicine. A good deal of human behavior can be understood, and indeed predicted, if we know apeople’s design for living.Many acts are neither accidental nor due to personal...
