Did you revolt against math when you found out that pi was some boring constant?
And not a fun dessert or even slice of pizza??

@ElwoodBlues triple differentials? 😩
ElwoodBlues · M
@ShepherdBard It's called vector calculus, and those are Maxwell's Equations. E represents an electric field, an B a magnetic field. The triple integrals integrate the whole of a 3D volume; the double integrals with a loop integrate over a closed surface containing said volume. On the right hand side, the upside down triangle is called 'del' and 'del dot' and 'del cross' are different partial derivatives of 3D vector quantities; also known as divergence and curl operators respectively.
When an electromagnetic wave (radio, light, etc) propagates thru empty space, a magnetic field in some direction rises and falls, inducing a perpendicular electric field to rise and fall, thus inducing a magnetic field, etc etc. At any point in space these fields have a magnitude and direction, so they are described by 3D vectors.

@ElwoodBlues I took calc 3 a bit over a year ago. It was a lot of work, a lot of the info didn’t stick because the pace was so quick. But I’m going back and learning from calc 1 a bit each day
