The omega equation is a culminating result in synoptic-scale meteorology. It is an elliptic partial differential equation , named because its left-hand side produces an estimate of vertical velocity, customarily [ 1 ] expressed by symbol ω {\displaystyle \omega } , in a pressure coordinate measuring height the atmosphere.
A sphere rotating around an axis. Points farther from the axis move faster, satisfying ω = v / r.. In physics, angular frequency (symbol ω), also called angular speed and angular rate, is a scalar measure of the angle rate (the angle per unit time) or the temporal rate of change of the phase argument of a sinusoidal waveform or sine function (for example, in oscillations and waves).
The formula is a combination of Ohm's law and Joule's law: = = =, where P is the power, R is the resistance, V is the voltage across the resistor, and I is the current through the resistor. A linear resistor has a constant resistance value over all applied voltages or currents; many practical resistors are linear over a useful range of currents.

Ohm's law was probably the most important of the early quantitative descriptions of the physics of electricity. We consider it almost obvious today. When Ohm first published his work, this was not the case; critics reacted to his treatment of the subject with hostility.
The mass formula was obtained by considering the representations of the Lie algebra su(3). In particular, the meson octet corresponds to the root system of the adjoint representation . However, the simplest, lowest-dimensional representation of su(3) is the fundamental representation , which is three-dimensional, and is now understood to ...
An experimental nasal spray has helped clear toxic protein buildups in the brains of mouse models of Alzheimer's. Its developers believe the spray may help delay Alzheimer's by at least a decade.
ω (omega) is the angle in the chain C α − C' − N − C α, φ (phi) is the angle in the chain C' − N − C α − C' ψ (psi) is the angle in the chain N − C α − C' − N (called φ′ by Ramachandran) The figure at right illustrates the location of each of these angles (but it does not show correctly the way they are defined).
