So Leave.EU is still active, and apparently last year they were soliciting a graphic to ridicule journalist Carole Cadwalladr:
As a mathematical scientist it strikes me as significant that she is considered to be discredited by association with three images: Flat Earth, Illuminati (though it looks to me like the Masonic eye from the US dollar bill), and what looks like a cheat sheet for an introductory electromagnetism course. Down in the corner we see that she’s been learning the right-hand rule for multiplying vectors. Right above it she has the formula for calculating power, which seems problematic.

I read it. As a lefty, I do not understand it. Care to explain?
I’m just trying to find some sense in the attempt to discredit someone with images of, among other things, the “right-hand rule”. (That’s the picture with the circles and the hand.)
The “right-hand rule” is one of the diagrams on the blackboard, that are supposed to show how weird and dangerous she is.
