Paper day! together with some colleagues we wrote an article about the boundary conditions between two media in relative motion.

As it turns out, we need to use the wrong boundary conditions to get the correct results!

In 1778 Sebald Justinus Brugmans discovered diamagnetism, and in 1845 Michael Faraday showed it to be a property of matter. (sharpgiving.com/thebookofscien)

A nice way to play with the fields and look at it...

Skeptoid #72: Electromagnetic Hypersensitivity: Real or Imagined? by Brian Dunning Some claim to be hypersensitive to electromagnetism. Science has already solved what's really going on.

I love the reasoning that even nothing is filled with something.
reminds me of the older ideas of which was created to explain how works in a vacuum. The difference being that there is experimental evidence of Quantum Foam.

My moment for today.

It’s one of my favourite lessons of Higher Physics.
Moving charge in a magnetic field. Cue a class of kids twisting their hands to work out which way the force points.

Being in Scotland, we call it the right hand rule with electron flow, but I’ve warned them others use conventional current.

Hey Physicists of Twitter, here is a very simple exercise for you. We have a battery with V=10 Volt. The five capacitors are identical, all with capacity C=10 microFarad.
Find the charge Q2 in capacitor C2!

How do Maxwell's equations predict that the speed of light is constant?🤔 (photo credit: Fermat's Library)

Maxwell's equations, a set of coupled partial differential equations (PDEs), describe the behaviour of electric and magnetic fields and predict that the speed of light is constant in all reference frames, which is a fundamental principle of the theory of relativity.

Magnetism - In 1600, William Gilbert experimented to determine the properties of magnets and declared that the Earth is a giant magnet. (sharpgiving.com/thebookofscien)
