Quantum mechanics is perhaps the most unintuitive theory ever devised. And yet it's also the most successful, in terms of sheer predictive power. Simply by following the math of quantum mechanics, incredible discoveries have been made....

If you want to make particles move really fast, you have to build a particle accelerator that is really big, right? Not anymore!

Quantum field theory is notoriously complicated, built from mind-bendingly abstract mathematics. But are the underlying rules of reality really so far from human intuition? Or are physicists just showing off? For better or worse, the...

Hank tells us about some developments that are being made in the dramatic area of laser tractor beams.

In this video Paul Andersen explains how a vector field shows the distribution of vector quantities. In AP Physics 1 student should be able to map and understand gravitational vector fields. In AP Physics 2 students should be able to...

Many thanks and shout-out to David Tong's lecture on Quantum Fields for inspiring this video. I highly recommend his free lecture series. In my opinion, he and Richard Feynman are two of the best educators...

Quantum theory solved many problems with classical theory - the photoelectric effect solved by Einstein, atomic model solved by Niels Bohr. But quantum theory had a high price - determinism. it introduced...

Summary:

If you point a powerful laser at the moon, and spin it 100 times per second, the dot on the moon will move 3X the speed of light. This is ok. The maximum speed limit is not a limit with which...

Why using magnets, not wheels, allows this train to defy gravity and reach record speeds without an engine. Physics - Electricity And Circuits - Learning Points. The Maglev train in China does not have an engine. Instead it uses...
