Remember when the operator x was for multiplication? Then for a while it was just a dot. Now it’s nothing, no symbol indicating multiplication. The dot became dot product and the x became cross product, both of which are some crazy vector jive.
So why the fuck did we ever use x operator to begin with?
You’ll see in a movie like a chalkboard covered in symbols and weird shit that’s supposed to seem like an exaggeratedly indecipherable mess of equations to the audience, but I’ll take a step back from a lecture’s worth of E&M notes and that’s exactly what physics student deals with.
