14TH December 1990.
Can be seen as the birth of quantum physics.
When one of my favorite scientist named Max Planck introduced a paper on black body radiation and gave
this equation E is equal to each new.
There he tried to summarize that radiations are particles and the packet of energy they possess is called
quantum.
The possibility of quantum phenomenon and blancs research was further confirmed by Einstein's photoelectric
effect.
Niels Bohr, atomic model.
Compton effect.
And Davisson Germar experiment.
These theories are considered old quantum theory, emergence of new quantum theory came from two pioneers
of quantum physics and two new fields within quantum physics evolved.
One is Matrix mechanics, led by physicist Heisenberg, who gave a very important theory of quantum
mechanics named Heisenberg's Uncertainty Principle.
And another field is Will Mechanics, led by Irwin Scrounger, whose theories are the building blocks
to study modern quantum physics, and we will study in this course in lot more depth.
And I will repeat, don't worry about these equations, you will get more clarity in four sections just.
