Mechanics 
and its 
Impact on 
Human Life
What is Quantum 
Physics?
• Quantum Physics also known as 
quantum theory or quantum mechanics 
is a major part of modern physics along 
with general relativity.

Use of quantum 
physics in daily life
• Today, every other thing is influenced by 
quantum physics. For example: 
Computers and Smartphone: The entire 
working process of computers is based 
on quantum physics.

Modern 
Semiconductor
• The phenomenon of band structure, 
which supports the modern 
semiconductor- based electronics, is 
fundamentally a quantum mechanism.

Lasers and 
Telecommunication
• The base of fiber optic 
telecommunication is quantum physics.
• The light sources that are used to send 
messages down the fiber optic cables 
are lasers that are quantum devices.

Perennial puzzle 
of consciousness 
• The perennial puzzle of consciousness 
has even led some researchers to invoke 
quantum physics to explain it. 
• That notion has always been met with 
skepticism, which is not surprising.

Measure some 
property
• Outcome of a quantum experiment can 
change depending on whether we 
choose to measure some property of 
the particles involved.

Consciousness influences 
quantum mechanics
• Today some physicists suspect that, 
whether consciousness influences 
quantum mechanics, it might in fact 
arise because of it. 
• They think that quantum theory might 
be needed to fully understand how the 
brain works.

Interactions of a 
quantum object
• Quantum effects such as superposition 
are easily destroyed, because of a 
process called decoherence. 
• This is caused by the interactions of a 
quantum object with its surrounding 
environment, through which the 
"quantumness" leaks away.

Quantum 
Properties
• In most physical phenomena we 
encounter in our everyday lives, we do 
not see these discrete amounts of 
energy; the quantum properties of 
particles are hidden from our eyes.
