I need to start a collection of "math things that really, really sound like wizard and/or cleric things."

If you're interested in my research:  program verification, type theory, domain theory, logic.

Funtastic Ferro Fluid!

Here’s a special piece of artwork that will make you go ‘wow’:

You may wonder, weren’t those liquid they had there? How could it acted as though it could move on its own will, solidified and formed spikes around those drill-like constructions? Quite a show-offish liquid we have here!

Well, the secret behind their ‘will’ lies at the fact that this liquid is ferromagnetic. Remember some principles of magnetism? Here’s one basic tenet: Opposites attract, equals repel!

(Psst, do you know that the earth is one gigantic magnet with two opposite poles at either end?)

Not all materials are magnetic. In terms of magnetic conductivity, matters could be classified as

Ferromagnetic literally translated as "magnetic like iron"; is materials which can be strongly magnetised

Diamagnetic  materials that resists magnetization and weakly repel magnetic fields outside themselves

Paramagnetic  objects can be induced and magnetized positively, but to a lesser extent as the ferromagnetic object

Magnetic behavior can be explained by the Domain Theory, read the stuff up!

If you would like to try it at home, here’s a link that is going to show you just how to do that:

Disclaimer: It’s going to get messy, so do conduct some precautions before attempting the experiment. You’ve been warned.
