In 1900, Max Planck, in trying to understand the mathematical principles behind blackbody radiation, postulated that energy was not continuous, but came in discrete amounts.
He admitted that this was a mathematical trick to make the model fit observations.
Nonetheless, his idea, of energy being quantised, was taken up by Albert Einstein to explain the Photoelectric Effect. Later it was taken up by Niels Bohr to understand the structure of the atom.
What was a 'mathematical trick' led to complete paradigms shift what is now known as Quantum Mechanics.
The following lessons explore the development from Max Plank to Schrödinger and Heisenberg.
 

1. Black Bodies and Planck

 

​2. Photoelectric Effect Explained

 
 

3. The Bohr model

 

4. De Broglie and the introduction of matter-wave duality 

 

5. The experiment that demonstrated that electrons act like waved

 

6. Compton scattering

 

7. Schrödinger's Equation

 

8. Heisenberg Uncertainty Principle

9. How a laser works
