Noun1.physical phenomenon - a natural phenomenon involving the physical properties of matter and energyphysical phenomenon - a natural phenomenon involving the physical properties of matter and energy
natural phenomenon - all phenomena that are not artificial
acoustic phenomenon - a physical phenomenon associated with the production or transmission of sound
atmospheric phenomenon - a physical phenomenon associated with the atmosphere
boundary layer - the layer of slower flow of a fluid past a surface
chaos - the formless and disordered state of matter before the creation of the cosmos
cloud - any collection of particles (e.g., smoke or dust) or gases that is visible
decalescence - phenomenon that occurs when a metal is being heated and there is a sudden slowing in the rate of temperature increase; slowing is caused by a change in the internal crystal structure of the metal
electrical phenomenon - a physical phenomenon involving electricity
electricity - a physical phenomenon associated with stationary or moving electrons and protons
energy - any source of usable power; "the DOE is responsible for maintaining the energy policy"
energy, free energy - (physics) a thermodynamic quantity equivalent to the capacity of a physical system to do work; the units of energy are joules or ergs; "energy can take a wide variety of forms"
power - (physics) the rate of doing work; measured in watts (= joules/second)
event - a phenomenon located at a single point in space-time; the fundamental observational entity in relativity theory
field of force, force field, field - the space around a radiating body within which its electromagnetic oscillations can exert force on another similar body not in contact with it
force - (physics) the influence that produces a change in a physical quantity; "force equals mass times acceleration"
hysteresis - the lagging of an effect behind its cause; especially the phenomenon in which the magnetic induction of a ferromagnetic material lags behind the changing magnetic field
resonance - an excited state of a stable particle causing a sharp maximum in the probability of absorption of electromagnetic radiation
mechanical phenomenon - a physical phenomenon associated with the equilibrium or motion of objects
opacity - the phenomenon of not permitting the passage of electromagnetic radiation
optical phenomenon - a physical phenomenon related to or involving light
force per unit area, pressure, pressure level - the force applied to a unit area of surface; measured in pascals (SI unit) or in dynes (cgs unit); "the compressed gas exerts an increased pressure"
reflexion, reflection - the phenomenon of a propagating wave (light or sound) being thrown back from a surface
refraction - the change in direction of a propagating wave (light or sound) when passing from one medium to another
resolving power, resolution - the ability of a microscope or telescope to measure the angular separation of images that are close together
resolution - (computer science) the number of pixels per square inch on a computer-generated display; the greater the resolution, the better the picture
conduction, conductivity - the transmission of heat or electricity or sound
propagation - the movement of a wave through a medium
fundamental interaction, interaction - (physics) the transfer of energy between elementary particles or between an elementary particle and a field or between fields; mediated by gauge bosons
surface tension - a phenomenon at the surface of a liquid caused by intermolecular forces
syzygy - the straight line configuration of 3 celestial bodies (as the sun and earth and moon) in a gravitational system
transparence, transparency - permitting the free passage of electromagnetic radiation
turbulence, turbulency - unstable flow of a liquid or gas
chop - the irregular motion of waves (usually caused by wind blowing in a direction opposite to the tide); "the boat headed into the chop"
floatation, flotation - the phenomenon of floating (remaining on the surface of a liquid without sinking)

"Visitors can watch the laser show closely, see interactive exhibits, paint with light, while we explain various mysteries and physical phenomenon.
But the distances between galaxies are so vast--are these both due to the same physical phenomenon? Or is it possible that the two sets of observations require two different physical forces?
The latter suggests, in a manner to be precise by Theorem 3, that only samples that describe a physical phenomenon (those whose ergodic limit is a "reasonable" probability) should be considered as samples for any physical "reasonable probability space." It is also apparent, as shown by Theorem 3, that a stronger theory can be established if other samples are not considered.
This converter, described in (http://www.nature.com/nphoton/journal/vaop/ncurrent/full/nphoton.2016.228.html#affil-auth) a study published this week in the journal Nature Photonics, exploits a physical phenomenon that causes the index of refraction for light in certain crystals to change in the presence of an external magnetic field.
