Magnets - how DO they work? We've got the answer for you, plus a bunch of weird fun magnet facts - where they got their names, why hitting some stuff with a hammer can turn it into magnets, and even why we feed magnets to cows, on purpose.

Neils Bohr said, “It is wrong to think that the task of physics is to find out how Nature is. Physics concerns what we can say about Nature.” Well it turns out that if we pay attention to this subtle difference, some of the most...

If you're lucky enough to find a glowing rock, it likely doesn't mean you're the chosen one. In fact, it could have to do with one of these five phenomena! Learn about the quantum mechanics of glowing rocks in this new SciShow Episode...

If you find a glowing rock, it probably doesn't mean you're the chosen one. If it's one of these five phenomena, it's quantum mechanics, not narrative significance.

How do foxes know where to pounce when they can't see their prey? There's evidence they're using the Earth's magnetic field to help.

The Stern-Gerlach experiment, which took place in 1922, was the most important proof that electrons have spin and that they have a spin quantum number. A stream of silver atoms was sent through an experiment using a magnetic field...

Materials can be classified based on their response to external magnetic fields. Diamagnetic materials are weakly repelled by external magnetic fields, while paramagnetic materials are attracted but lose their magnetism in the absence...

In this representation I discuss the main principles of quantum mechanics behind the quantum computer. and How to build a device that can manipulate the energy operator of the Schrodinger Equation for an electron to change its spin...

In this part we build three quantum computers that can process simple commands by manipulating the Energy Operators in Schrodinger Equation. <br/>
