Actually, just the left hand side of the equations, because it looks better that way. The right hand sides are just a click away.
E and B are the electric and magnetic fields, respectively. ∇ is the “del” operator.
The divergences ∇ · E and ∇ · B are the “fields emanating from the sources.”
The curls ∇ x E and ∇ x B are the “circulation of the fields.”
I like to think
(it has to be!)
of a cybernetic ecology
where we are free of our labors
and joined back to nature,
returned to our mammal
brothers and sisters,
and all watched over
by machines of loving grace.
— Richard Brautigan from All Watched Over by Machines of Loving Grace
There is nothing wrong with your television set. Do not attempt to adjust the picture. We are controlling transmission. If we wish to make it louder, we will bring up the volume. If we wish to make it softer, we will tune it to a whisper. We will control the horizontal. We will control the vertical. We can roll the image, make it flutter. We can change the focus to a soft blur or sharpen it to crystal clarity. For the next hour, sit quietly and we will control all that you see and hear. We repeat: there is nothing wrong with your television set. You are about to participate in a great adventure. You are about to experience the awe and mystery which reaches from the inner mind to – The Outer Limits.
