michelson morley experiment explained
In Atal Tinkering Labs ATL, More Info | No commentIn this video I review the famous Michelson Morley experiment, what is known as the most famous null result experiment. Although impossible to reconcile with the understating of Physics at the time, it became fully understood in the context of Einstein’s Theory of Special Relativity. I use a couple of useful analogies to help you understand the experiment.

Meissner Effect demonstrated (basic)
In Atal Tinkering Labs ATL, More Info | No commentA video that demonstrates the Meissner Effect. Produced with the Australian HSC in mind. This does abruptly end as I had to remove an erroneous section. Nonetheless, it’s the meissner effect that causes levitation. Any further explanation for the stability of the levitation is Quantum related and beyond the school of a high school student.

NSW Physics review – dot points 9.4.4
In Atal Tinkering Labs ATL, More Info | No commentThe in a series of short videos, I review the dot points in the NSW HSC syllabus. I won’t go into the full details of the physics of each point, but I will touch on them discussing the nuances of each dot point. I this set I review section 9.4 Ideas to Implementation part 4 – on superconductors
