I read an article about this genius recently in a ham radio magazine and was directed to the below YouTube video. One of her subjects is “Maxwell’s Equation in 45 Minutes.”
I can’t begin to understand any of this lecture and I challenge my readers to get through it. Feel free to skip to the next post. The T shirt with the equation is apparently quite popular.maxwells equation

Here is what Wikipedia says about Maxwell’s equation:

In the 1860s James Clerk Maxwell published equations that describe how charged particles give rise to electric and magnetic force per unit charge. The force per unit charge is called a field. The particles could be stationary or moving. These, together with the Lorentz force equation, provide everything you need to calculate the motion of particles in electric and magnetic fields.

Maxwell’s equations describe how electric charges and electric currents create electric and magnetic fields. Further, they describe how an electric field can generate a magnetic field, and vice versa.

The first equation allows you to calculate the electric field created by a charge. The second allows you to calculate the magnetic field. The other two describe how fields ‘circulate’ around their sources. Magnetic fields ‘circulate’ around electric currents and time varying electric fields, Ampère’s law with Maxwell’s correction, while electric fields ‘circulate’ around time varying magnetic fields, Faraday’s law.
