#42 Angular Momentum

Yeah, maybe they’re not just trying to catch their tails…
Today, some classical mechanics with conservation of angular moment: A basic and still beautiful concept.

#41 Graduated

If everything goes right, I’m graduating in less than a month That’s just how I’m feeling about my close future.
Cheesus, exam period is about to start… wish me luck!

#40 Event Horizon

This semester I'm studying cosmology and it's the time to learn about cosmologic horizons. Event horizon is probably the saddest concept I've ever heard! Just listen: Two particles separated farther than the distance of the event horizon will never EVER meet each other in the history of the universe due to its accelerating expansion. Isn't it devastating? But hey, don't get down, every single partcile was in contact with others at the start, so they will never forget about each other. Thats the reason for thermodynamic equilibrium in the universe! :)

#39 Exercise

Who needs to go to the gym when you have special relativity?
I was supposed to be studying, but... too tired.... blergh. 

#38 Quarkonia

Quarkonium, in plural Quarkonia are flavorless mesons composed by a quark and its own antiquark, like charmonium and bottonium. Learn more here.
So, we were in our Nuclear Physics class when we read the term 'quarkonia' in our text book. My mate Sara suggested that it sounded like the name of some fantasy world and thats how The Chronicles of Quarkonia came up!

#37 Compliment

Bc+ particles are B mesons made of a c (charmed) quark and a b (bottom or beauty) antiquark, so it is a meson that has a quantum number for 'charm' and for 'beauty'. Aren't they appropiate? The nicest kind of particle! I'll totally date them. For more information check Wikipedia.
This one is for a very special philosopher ;)

#36 Flavour

Because no, angular momentum, spin or principal quantum numbers are not enough to describe particles. Physicist need MOAR and to describe quarks it is necessary to define a NEW ONE, and, sure, why not say... flavour quantum number? Because, of course, quarks are tasty and you can differenciate them by the way they sweeten your coffee. Other day, we can talk about colours... because they're also colored you know. Read more.
