It has been quite a week.

I went to see Hans Zimmer at the Palais des Congrès and it was an amazing performance. Probably one of the best experience of my life. The Orchestra played Gladiator, The Lion King, Pirates of Caribbean, Inception, Interstellar, Batman and more and you felt everything. I recommend it to anyone. Here are some excerpts, but it's orders of magnitude better live :

I have some interviews coming this friday and next week for 6-months internships in Private Equity, Management Consulting and M&A. It's going to be quite hard but I'm going to prepare and we will see how it goes.

I went to see a conference of Jean-Yves Le Gall (CEO-equivalent of the CNES (Centre National d'Etudes Spatiales) -equivalent of the NASA here) and it was quite interesting:

- Fun facts: it seems that the main reason the ISS stays up in the air is because we don't know how to bring it back to Earth. (the size of this thing is crazy: length 78.8m (239ft) ; width 108.5m (356ft) ; height 20m (66ft))

- Google X works on a live Google Earth, I didn't know this. It could have tremendous application, especially for self-driving cars if the network knows in advance where are moving things and in which directions.

- Jeff Bezos really knows his science, he was able to talk at a rocket-science level for 2 straight hours with specialists and journalist at a conference 2 weeks ago.

- There was a dinner between Obama, Hollande, Elon Musk, Jean-Yves Le Gall and others. During the dinner, when Jean-Yves asked Musk about a possible collaboration, Musk told him that if he wanted to collaborate he would have to set up an appointment with Human Resources at SpaceX. Typical Musk.

- Ariane 6 is going to be completely new and have a cost effective approach, trying to respond to market needs (3D printing of parts, reusability, etc.)

- Concerning SpaceX, his group of experts told him that the design of the rocket wasn't going to work and was going to explode at high altitude due to fluctuation. That didn't happen. They also told him that the first stage would just go through the barge, sinking both the first stage and the barge. That didn't happen either. So now they take new entrants way more seriously.
