Reaction formation. In psychoanalytic theory, reaction formation (German: Reaktionsbildung) is a defense mechanism in which emotions, desires and impulses that are anxiety -producing or unacceptable to the ego are mastered by exaggeration of the directly opposing tendency. [1]
The uncanny valley (Japanese: 不気味の谷, Hepburn: bukimi no tani) effect is a hypothesized psychological and aesthetic relation between an object's degree of resemblance to a human being and the emotional response to the object. Examples of the phenomenon exist among robotics, 3D computer animations and lifelike dolls.
Specifically, they are the inverses of the sine, cosine, tangent, cotangent, secant, and cosecant functions, [ 4 ] and are used to obtain an angle from any of the angle's trigonometric ratios. Inverse trigonometric functions are widely used in engineering, navigation, physics, and geometry.
'Irony' comes from the Greek eironeia (εἰρωνεία) and dates back to the 5th century BCE.This term itself was coined in reference to a stock-character from Old Comedy (such as that of Aristophanes) known as the eiron, who dissimulates and affects less intelligence than he has—and so ultimately triumphs over his opposite, the alazon, a vain-glorious braggart.

Fizeau interferometer. A Fizeau interferometer[1] is an interferometric arrangement whereby two reflecting surfaces are placed facing each other. As seen in Fig 1, the rear-surface reflected light from the transparent first reflector is combined with front-surface reflected light from the second reflector to form interference fringes.
Newton's laws are often stated in terms of point or particle masses, that is, bodies whose volume is negligible. This is a reasonable approximation for real bodies when the motion of internal parts can be neglected, and when the separation between bodies is much larger than the size of each.

A Shepard tone, named after Roger Shepard, is a sound consisting of a superposition of sine waves separated by octaves. When played with the bass pitch of the tone moving upward or downward, it is referred to as the Shepard scale.
