111Coffee extraction — Main article: Coffee preparation Proper brewing of coffee requires using the correct amount of coffee grounds, extracted to the correct degree (largely determined by the correct time), at the correct temperature. Contents 1 Concepts 2 Extraction… …
112Measuring instrument — Captain Nemo and Professor Aronnax contemplating measuring instruments in Twenty Thousand Leagues Under the Sea …
113Potential energy — This article is about a form of energy in physics. For the statistical method, see Potential energy statistics. Classical mechanics Newton s Second Law …
114Potential flow — streamlines around a NACA 0012 airfoil at 11° angle of attack, with upper and lower streamtubes identified. In fluid dynamics, potential flow describes the velocity field as the gradient of a scalar function: the velocity potential. As a result,… …
115Least squares — The method of least squares is a standard approach to the approximate solution of overdetermined systems, i.e., sets of equations in which there are more equations than unknowns. Least squares means that the overall solution minimizes the sum of… …
116Hysteresis — Not to be confused with Hysteria. Fig. 1. Electric displacement field D of a ferroelectric material as the electric field E is first decreased, then increased. The curves form a hysteresis loop. Hysteresis is the dependence of a system not… …
117Conservative vector field — In vector calculus a conservative vector field is a vector field which is the gradient of a function, known in this context as a scalar potential. Conservative vector fields have the property that the line integral from one point to another is… …

119Gunn diode — A Gunn diode, also known as a transferred electron device (TED), is a form of diode used in high frequency electronics. It is somewhat unusual in that it consists only of N doped semiconductor material, whereas most diodes consist of both P and N …
120Atmospheric electricity — is the regular diurnal variations of the Earth s atmospheric electromagnetic network (or, more broadly, any planet s electrical system in its layer of gases). The Earth’s surface, the ionosphere, and the atmosphere is known as the global… …
