Mechanics
Branch
of physics which deals with behavior of environmental objects under force.
(or)
Branch
of physics which deals with energy & forces acting on materialistic bodies
in motion is called mechanics.
Median
The median, as
implied by its name, is the middle value in a distribution of values. To
calculate the median, simply sort all of the values from lowest to highest and
then identify the middle value.
Medical
Physics
Branch
of physics which uses physics principles in practice of medicine. It is most
often used to describe physics applications related to use of radiation in
medicine.
Medical physics is a branch of physics dealing with
the application of physics to medicine, most generally in three areas: Diagnostic imaging physics, Nuclear
medicine physics and
Radiotherapy physics. While nuclear medicine
concentrates mainly on application of unsealed radio nuclides for diagnosis and
treatment of disease, the use of x rays forms an important component of
diagnostic radiology as well as radio therapy.
Mega
Prefix in metric
system denoting a factor of million i.e. 106 of basic unit.
Meissner
Effect
The property of
exhibiting perfect diamagnetism by super conductor is called Meissner effect.
Melanin
It is pigment on
human skin which absorbs UV rays.
Melody
When two or more
notes are sounded one after the other, the combined note producing pleasing
effect on the ear, is called melody.
Melting
Physical
process which results in phase transition and a substance from solid to liquid
under influence of temperature.
Melting
Point
Temperature at which solid changes its state from solid to
liquid at atmospheric pressure.
Membrane
A semi permeable thin layer of material
capable of separating
MEMS
A large number of miniature mechanical
devices that are integrated with electrical elements on a silicon substrate.
Mechanical components act as micro sensors and micro actuators and are in form
of beams, gears, motors and membranes. In response to micro sensor stimuli, the
electrical elements render decisions that direct responses to the micro
actuator devices.
Meniscus
The curved upper
surface of a non turbulent liquid in a container fixed close to the surface of
container, caused by surface tension. It can be either convex or concave.
Meson
Modern definition
of Meson is that it is a particle that is believed to be fundamental, not
composite capable of participating in strong interactions. It is a Boson
Meta
Stable State
Atomic or
nuclear energy level, which has life time of order 10-3 sec or more.
Metallic
Bond
In
this type
of bonding, the valence electrons which hold atoms together are not bound to
individual atoms or pairs of atoms but moves freely throughout the whole metal.
Meteor
It is a small
body of matter from other space that enters the earth’s atmosphere appearing as
streak of light.
Meteorology
It is science of weather. It is
interdisciplinary science because atmosphere, land and ocean constitute integrated
system. The 3 basic aspects of meteorology are observation, understanding and
prediction of weather.
Mho
Unit
for electrical conductance; the name suggested by Thomson.
Refer
Siemens also.
