Par l’absurde, supposons que le Père Noël existe vraiment.
Il y a approximativement deux milliards d’enfants de moins de 18 ansOk, so now you’re a PhD, and you’re looking for a job in the industry, because you realized that academia was rotten, and you have no fear of making a step ahead.
You’re looking for a super position, but you will face a lot of incomprehension :
But no hope is lost !(edit December ’13) If you live in the Bay Area, and you are interested in doing a job in data science, you might want to enroll Insight, which is a 6-weeks program for postdoc on the topic of data science. There are about 4 sessions a year (the January one is beast suited for foreigners, since they can have interviews immediately after, apply for a H1-B visa right for the April deadline and start working in October). It is a fully paid fellowship, the attached string is that you have to go into interviews with companies that are partners to the program (facebook, LinkedIn, etc.) and you might be required to give a hand once in a while.+1 in my Nobel Prize Drawings Collection !

Le monde nous apparaît souvent tel qu’il est représenté. Aussi, amusons-nous à changer des perspective !
Si le monde n’était pas gauche, peut-être que nous verrions les choses sous un autre jour.A propos de Grèce, vous qu’elle est au Sud. Et que si l’on met le Sud en haut (pourquoi le devrait-on systématiquement le mettre en bas? pourquoi la droite et la gauche s’inversent dans un miroir, et pas le haut et le bas ? -réponse ici, section ‘miroir”), nous voila avec une nouvelle image mentale !
La terre est ronde. Le chemin le plus court entre deux point est la ligne droite. Voici la liste des raccourcis :
L’Afrique est un grand continent, plus qu’on ne se l’imagine car les projections ne lui font pas honneur (il est coupé en deux par l’équateur). Pour preuve:
Et le Pacifique, un grand océan (il faut bien remplir 71% en eau la surface de la Terre!).

edit 12 septembre 2013 :I recently came back from San Francisco and LA, where I had an interesting conversation on copyrights and the characteristics of a genuine piece of art.
It started with the fact that Shepard Fairey who created the iconic “Hope” picture of Obama has been sued by Mannie Garcia, the photographer who took the original picture and won (the case is not settled, though).
This reminded me of the (more confidential) work of Andy Baio, who revisited Miles Davis in 8 bit : Kind of Bloop. Strangely enough, he was sued not for the music, but for the album cover which was considered to be too close to the original photograph !

So you’re smart and want to start a PhD ? Here are a few considerations and advices that might help you.
I won’t tell you whether it’s worth or not. I loved it, some hated it. Do don’t do it to earn an extra diploma, but because you are truly interested in science. And I mean it !

Quelques remarques qui ressortent de l’entretien
No shame !
That’s what Nature said to those Prometheuses who wanted to steal the neutrinos from the realm of light (via).
No shame, because they put themselves at risk, claiming that the centenary rule that nothing can go faster than light might not be so unbreakable, while keeping their calm at all time.
The best is their allegations re-opened the debate on what the speed of light really is the limit of.
Even though I’m not a specialist in special relativity, I was pleased to hear the crazy theories like this one :The speed of light is like a barrier. You cannot cross it, but you can be already on the other side, where the neutrinos might be.
Photons are exactly on the wall : they cannot go any slower or faster.(as heard on the radio).
I liked this picture because it relates to two (mis?)conception that I have.
