Since this is my first blog post I have decided on the topic of the Meissner effect, or Quantum levitation. this is the phenomenon of a superconductor levitating* when exposed to a weak magnetic field

Superconductivity was discovered in 1911 on April 8th by a dutch physicist by the name of Heike Kamerlingh Onnes.
He was experimenting the resistance of mercury at cryogenic temperatures using the newly discovered liquid helium as the refrigerant. at the temp of 4.2 kelvins (-452 f, -268 c), he observed the resistance of electricity through the mercury had disappeared (I will go more into how it works later). he continued his study and later in 1913 he discovered that lead would superconduct ar 7 k (-447 f, -266 c), and in 1941 Niobium nitride was discovered as a superconductor at 16 k (-430 f, -257 c)
And in 1933 due to extensive research for how superconductivity works, it was discovered that superconductors expelled weak magnetic fields
How it works:
In all materials, there is a certain resistance to the electricity running through them. Like wood, for example, it does not allow electricity to run through it and therefore turning all the electricity into heat. This is how toasters work, they have electricity running through a semiconductive wire to create heat, to then cook your toast.
But with superconductors there is no resistance to the electricity running through them, therefore allowing infinite amounts of electricity to run through them without losing any of it to heat.
Superconductors levitate by expelling weak magnetic fields, they do this by creating electric fields, therefore holding the superconductor in place.
Another thing it does is, lock itself in place through quantum locking
it allows some of the field to move through the superconductor but locks them in place therefore not letting the superconductor move freely, here is a video showing this:
What could we do with this?
with this technology we could make hoverboards (if Hendo doesn't come out with one first). Self-driving, levitating cars. and bullet trains with literaly no friction againts the track
