#21 Tunnel Effect

You only need to believe.

#20 Divergence

This is called the Gauss's law for magnetism, and it is one of the Maxwell's equations that form the foundation of classical electrodynamics, classical optics and electric circuits. Gauss's law for magnetism states that there are no isolated magnetic charges but there are dipoles which generates the magnetic field. As you can check easily, when you have a magnet it always have a north pole and a south pole, and if you cut it apart, you'll have two magnets each of them with its own north and south pole. You can't have a north pole in one hand and a south pole in the other. That appropriate behaviour of magnetic charge make it possible for the compasses to work and to point the north pole of the Earth.

So, it is VERY important. Never EVER forget that divergence of B is zero, you'll never know when this information would save your ass.

Schrödinger's Cat experiment explained for programmers.

#18 Entropy

 

Cats do a great job keeping nature laws as they should be. They don't even need to be quantum cats to increase the entropy of every place they walk in. 

Sorry for the great delay since the last entry. I've been very busy with the new year start at college, but now I collected some new ideas thanks to my friends and classmates. Thanks to all who support Schrödinger's Cat!

#17 Boundary Conditions

Quantum cats have a lot of problems in their everyday life, but it's easier to solve them using periodic boundary conditions.

#16 Circuits

This is a little joke dedicated to my great friend Víctor, who is leaving on monday to stay the whole year studying in England with an Erasmus scholarship. I'm gonna miss him so much since he's my best friend at college and we've passed the last 4 years sitting together in class, chatting, laughing and making fun of everything just like 10 years old kids (all teachers probably hate us). I don't know what am I going to do without him. Seriously, I'm screwed, he was the smart, I need him to solve the problems and explain them to me! (Joking). This picture is something we usually drawed on our Electronics notes. Since we hated that subject and solving circuits is just a nightmare, we usually added cats to make them... furrier. It's funny because this circuit doesn't even have nodes.

Have fun in Manchester Víctor! I'll miss you!

#15 Classic

Probably the most classical, typical and still hilarious physics joke. Approximations, approximations everywhere.

I'm starting a new year at college next week so probably I won't have all the time I'd like to draw a new strip every day. The good news is that I'm sure new subjects will inspire new funny facts about physics.

#14 Notation

Dirac notation may be tricky sometimes, but it is very useful for describing quantum states.

#12 Tricks

Some people may think that Schrödinger's cat is very bad doing tricks, but be actually plays dead all the time. He plays alive at the same time. Well, it's complicated.

#11 Degenerate level

I'm not very into pedobear jokes, but seriously, quantum physics deserves it with all those degenerate levels and perturbed states and s**t.

#10 Curiosity

Thanks to Peube for suggesting the idea, unless this is probably not what he was thinking about :)
