few days ago I set out to read History of Time by Stephen Hawking, with the intent and the illusion of understanding, this time, all that the theory of relativity, quantum mechanics, particle physics ...
At first, I must say, the matter seemed very easy and understandable, but once the dedication, he began to become increasingly arid and convoluted and I confess I've reached the end sweaty and tired, even stiffness, and the feeling of not having very well aware of issue. But hey, one thing I understood.
I especially liked a kind of narrative flow that runs under the body of theory. It is like the history of successive scientific advances, sometimes simple matter of fluke, which have been making progress of science, both as sidereal movements of the smallest quarks. Within these small advances, my favorite is undoubtedly the Pauli exclusion principle.
This is Pauli
According to this principle, Pauli made, there can be two particles in the same place at the same time. Or what is the same: if a particle is in one place, there can be another time in that site. You can get one and move it, or throw to one side, or even destroy it, okay, but what is the two at a time, in the same place at the same time, they can be. Come on, do not. That is, or is one or the other, but not both simultaneously. It is impossible.
In formulating this principle, gave Wolfgang Ernst Pauli the Nobel Prize in 1945. I do not mean anything, the Academy Sweden knows better than I how awards the Nobel Prize in Physics, but much like the Pauli principle I have heard in many bars are rotated
Abar and people screaming from the bottom "here we do not more", and which are at the door, despite everything, trying to find a place but no way is impossible. There is no place to enter, even if pushed. One hopes that time comes to fill a place. Pauli puffing a pipe
On the Pauli principle, another physicist, named Hund, established a rule that, as I understood, dictates that orbitals are filled, the unpaired electrons form a second orbital. Or what is the same, and in the case of our example, go to another bar or even founded an establishment, as in the originally wanted to go no place. No, no place, no effort, it makes the Pauli exclusion principle.
A Friedrich Hund did not get the Nobel Prize. Sometimes, truth is, the Swedish Academy make some injustices that ... Anyway, back each other. I do not interfere.
This is Hund
The fact is that, under Pauli exclusion principle and Hund's rule explains much of the molecular structure of the universe. What, blogger friend. I, just in case, I will take to present here a phenomenon that I observed the whole life and that nobody has been able to give me an explanation. Is this: oranges and mandarins wedges are always odd. Sometimes 9, sometimes 11, but always odd. Try it if you want, as I did: for more oranges or tangerines to open, and although they have different fruit stands, the segments will be odd, inevitably. And this why? I do not know. By the way, as I say, I expose, everything will come someone reads it, and it would be the key to explain the performance of our cosmos. With what science and come to fruition thanks to the so-called "principle of odd Baquero.
