What is Quantum Mechanics??/

Evolution

Role in daily life

Uncertainity principle

Application

Magical Effect

Difference between classical and quantummechanics.

Unsolved questions.

Our views.


3/14

If Classical Physics describes the world to be

deterministic where the entire future course

is predecided, quantum physics puts up a

theory based on the assumption that world isprobabilistic where the events take place on

random chances.

Einstein States:

According to the assumption to be

contemplated here, when a light ray is

spreading from a point, the energy is notdistributed continuously over ever-increasing

spaces, but consists of a finite number of

energy quanta that are localized in points in

space, move without dividing, and can beabsorbed or generated only as a whole.

In 1900, Max Planck suggested that

electromagnetic energy could only be

emitted in quantized form.

In 1905, Albert Einstein Explained thephotoelectric effect i.e. light itself consists

of individual quantum particles (photons).

In 1925, Wolfgang Pauli Outlined the Pauli

exclusion principle which states that no twoidentical fermions may occupy the same

quantum state simultaneously.

Gravitational Effect

The force between two matter particles is pictured

as being carried by a particle of spin 2 called the

graviton, thishas no mass of its own.

Electromagnetic Force

The electromagnetic attraction is pictured as being

caused by the exchange of large no. of virtual mass

less particles of spin 1 called photons.


7/14

Nuclear force

It is responsible for radioactivity & which

acts on all matter particles of spin such as

photons and gravitons Strong Nuclear Force

It holds the quarks together in proton and

neutron, and holds the protons and neutrons

together in the nucleus of an atom. It isbelieved that this force is carried by another

spin-1 particle called the Gluon.

Any two variable that do not

commute cant be measured

simultaneously-the moreprecisely one is known the less

precisely other can be known.

HxHp "!h/2It can be proved using the properties

of fourier transformation.

In classical mechanics there is pre

determined that what will happen in

th

e past, present and future..But in quantum mechanics past,

present and future mingle with each

other and there is no surity of any

thing to be happened.


11/14

Rigidity of the surface of the solid material.

If there is sun and we are not going to

measure any of the effects of the sun then

there is no surety of existence of the sun andsame is the case for every object.

It can be the case that the judges sitting for

judgement, judge the candidates before the

performance of the candidate.


12/14

Why the events occuring in this

universe is determinstic even if the

quantum mechanics is working in the

small scale??

How can we satisfy the relativistic

theory, which is the theory for very

large objects, with the quantummechanics which is the theory of

very small??


13/14

There exists two type of universe, in first

there is energy constant and time vary, and

in second time is constant and energy is vary.

If we mix up those two universe then we canget the exact picture of the universe which is

present today.

At a time only one event can occur in this

universe
