Hydrogen atom
Large metal plate,
driven up and down. put sand on it and the places that it doesn’t move are nodes
Wave function depends on (radius, angle and
time) *partial diff. equation
They knew how to figure waves out with Newtonian
physics
Then they could identify element with their
spectrum with their wavelengths
So
we could figure out what the stars are made of
1870s spectrum of hydrogen was measured
very well and we knew where the lines and the wavelengths came together
High
school teacher - Balmer figured out that the
successive wavelengths
At this point it was just a puzzle
Rutherford said there was a nucleus
Bohr says that if the angular momentum of
the electron is quantized
Figured
out that the energies
Lyman
series n->1
Balmer series n->2
But
no one could understand anything else about other elements
1925.
Heisenberg
Got
PhD barely
Then
he got hay fever really bad afterward
Founded
quantum mechanics from making tables
Max
Born realized that he was using matrixes
He
called it matrix mechanics
Hilbert- great mathematician
Turn
them into partial differential equations
Schrodinger came up with his equation using
the partial differential equation
Schrodinger found that if he found that
there was a connection about heisenburg's tables and
Schrödinger's wave function
19025-1930 Then people were happy and people
found wave functions for everything
The laws of chemistry were the laws of
quantum mechanics
(if there's a frequency f1 and f2, then you could find a
frequency f3 that was f1 + f2
