Imagine a knotted wire with electric charge distributed uniformly along it. What do the equipotential surfaces around it look like? The animation below, by my student Max Lipton, shows one example. We’re also studying how many zeros exist in the electric field around the knot. https://t.co/0gr6oPERzx
