Ordinary day

Yes, there are some days when you start thinking : “Hey, this day is like every other day!”. Today is a day like that. Woke up at 6 to catch the 6:44 train to go to Paris, overwhelmed by the crowd inside. Everything’s dark. 1 hour and two connections inside Paris later, it was still dark outside. Wow, that’s gonna be a hell of a day !

 

Three lessons this morning, like every monday. I’m starting to believe that mathematics are the most complicated science ever. The teacher was talking about injections, surjections and bijections…mmmh I think I’ll Google it because I really didn’t get the point. Did you know that ? A function is bijective (one-to-one and onto) if and only if (iff) it is both injective and surjective. (Equivalently, every element of the codomain is mapped to by exactly one element of the domain.) A bijective function is a bijection (one-to-one correspondence). (credit to wikipedia.org). Well, now you know
Then came the electronic lecture. This week is an exams week, so everyone’s stressed out, nobody seems to understand what the teacher’s saying. He was talking about Bode’s diagram, and tried to make us understand what does resonance looks like in a RLC circuit, but we were elsewere, drowned between resistors, capacitors and inductors. We were suddenly woken up by the fire alarm. It was just a test. Ten minutes after, we were sleeping again…”Oh, it’s already 11:30 ! It’s time for the optics lecture !”. During weeks, we have been studying lenses, mirrors, prisms, but now she’s mixing everything together. That’s quite funny though. I like optics !
Just an hour to eat, and there you go, optics again ! Yeah !

 

School finished at 4, but I’m so tired, I almost slept reading the newspapers in the train that was taking me back home. Like every Monday, the first thing I do is to watch the new Desperate Housewives (well, it still isn’t there…). Oh, it’s still dark outside, it is as I never saw the sun today !

 

So, that is the end of a ordinary day, before the beginning of another, tomorrow…
