Quantum Mechanics for Blondes

At one of the drunkards of the “Popular Mechanics” college, we talked about science.

Again, some motherly words are written in the magazine! Complaints from the advertising department.
Where is?? to
“Boh-ze-en-stein-ovskiy Kon-den-Sat” is the name of the Not only does it break the tongue, it is not clear what it is and what it is about! You can’t explain it to ordinary people.

Even this way? Well, here is the boson condensate and quantum effects for blondes.

There are two types of particle people, “boys” and “girls.” The boys are dressed in pants that take 1 meter of canvas. This is a whole back. These particles are called bisons. The girls are dressed in sweaters that go 0.5 meters of canvas. This is a half-whole spin, and the girl particles are fermions.

They behave differently.

When the bosons gather together for a purely male party and discover that they are all dressed in absolutely the same costumes, they smile joyfully, sit next to each other, knock each other on the shoulder, give each other a beer, become best friends and act as a whole. This is the boson condensate (it is Bose-Einstein condensate). And when there is a scream "Our beaten!" all the particles-boys strive to defend - in the same direction and without interfering with each other. This is superfluidity.

And when the girls-fermions, gathered for the maid, find that they wear the same dress or sweat, they whisper, turn away and try not to get close to each other and not to sit on the neighboring chairs. This is the principle of Paulie’s prohibition.

Now imagine a shopping center with two entrances-outputs from different sides. This is a conductor. Inside there are many shops and boutiques. This is a crystal grid. If you run through one entrance a particle-girl (Fermion), then instead of going straight through and out on the other side, she will experience numerous clashes with shops, and will come out with a weight-loss wallet. This is an electrical resistance mechanism (electrons are fermions).

And now imagine that at the entrance a girl meets a girlfriend, and they get stuck in tongues and start talking about fashion, hairstyles and boys. In this case, two girls (fermions) act as a single whole. This is a couple. Enthusiastic about talking, the friends do not notice the shops and go through the shopping center, without experiencing clashes with the boutiques and without spending a penny of money, that is, they behave exactly like a boy (bozon). It is superconductivity.

Well, now you know as much as the students of physics will learn in the course of a year of quantum theory. Well almost.
