Equilbrioception is also how we can sense acceleration and gravity. We also have chronoception, an inner sense of timing, which explains how you know it’s about 2:30 without checking. 

Other animals can sense water currents and pressure, as well as electric and magnetic fields, among other things. We too can sense magnetic fields to a degree – if you’re willing to get magnets placed in your fingertips.

Nature is amazing in the breadth of things for which it can adapt, and the way it does so.

Crystalline Candleholders Made Using The Magic Of Magnetism

Jólan van der Wiel is a Dutch designer harnessing the power of nature to create unbelievable forms. His candlesticks begin as resin packed with iron oxide. Then, through a pulley system fitted with large magnets, the  resin is pulled along the magnetic field lines into shapes that represent a freakin’ force of physics, visualized right before our eyes. The invisible made visible.

When the resin sets, the magnetic field spikes are written in air forever, with no human intervention!

This is an incredible idea. What better centerpiece could you want?

It has baffled scientists for while now why the Sun’s atmosphere is hotter than its surface; a situation akin to having to shed clothing as you climbed Mt. Everest. Recent mathematical and astrophysics research from the University of Sheffield indicates that there are many magnetic plasma vortices (tornadoes) that bring up energy from inside the Sun and release it into the atmosphere. They’re relatively small compared to some of the ones that make the news occasionally, but still reach sizes greater than Great Britain and temperatures of several millions degrees kelvin.

Not only is the research answering questions about space, but the applications are important here too. If we can learn to use similar magnetic fields to control plasma here, there are ways to produce clean, green energy. The more ways we can do that, the better!

Quantum levitation: super-cooled metals let off magnetic fields, so when metal disks are dipped in liquid nitrogen the will levitate and follow a magnetic track. Even if it’s upside down! This demonstration was run by Boaz Almog, from Tel Aviv University, and was a popular stop at the World Science Festival in Brooklyn. Obviously there is a ton of practical uses, like more efficient trains. But we are all really just hoping for hoverboards, aren’t we?
