Are astronauts weightless? Einstein’s happiest thought | Science4All 14

Standard

Finally, here was my first video on general relativity per se. And it starts with a basic but incredibly deep question: Are astronauts weightless? Pondering similar questions (there were no astronauts back then) would lead Einstein to the happiest thought of his life… and for good reasons. It might be the most dramatic thought (in physics) I’ve ever encountered!

Despite a few technical issues and the smallness of the number of views, I still regard this video as my best one yet. Please let me know what you think 😛

Between Two Stools

Standard

Innovation lies at the interfaces of disconnected fields. Everyone knows that. And you might think that the world of scientific research is the ideal location for such an innovation. Well, from my (young) experience, interdisciplinarity is mainly an empty intergalactic void, far from any of the gigantic clusters of research groups. 

I’m feeling down. My first research paper doesn’t seem to fit anywhere. Operations Research has rejected it, claiming that it should be Games and Economic Behavior paper. But game theorists argue that it belongs to operations research. Meanwhile, Mathematics of OR asserts a lack of mathematics, and Management Science affirms an insufficiency of applications. Weirdly, no one criticizes the quality. But all disapprove the relevancy for their own journals.

So far, I do not feel at the interface of anything. I’m feeling like falling between two stools.

Ma Thèse en 180 Secondes

Video

Cette vidéo est celle de ma présentation au concours “Votre Soutenance en 180 Secondes” organisée par l’ACFAS en 2013. Allez voir mon profil sur leur site !

Vous pouvez en savoir plus sur ma thèse en lisant mes articles Science4All sur la théorie des jeux, la conception de mécanisme et sur la définition de l’équité. En attendant les articles Science4All qui seront plus directement liés à ma thèse, mais qui ne sortiront malheureusement pas tant que je n’aurai pas publié dans les revues mathématiques !

My First Post

Standard

Hey guys,

I’m currently travelling alone across Indonesia. This country is wonderful, and I have so much to tell you about it! Also, I’ve just been to the very interesting BtSM2013 colloquium, where I learned so much about… learning! So, in a moment of loneliness in one of the long bus trips I’ve had, I’ve decided to launch this new blog to share these adventures and ideas with you guys!

As opposed to what I do on Science4All, we’ll be having a more informal conversation. Plus, I won’t have to restrict myself to explaining some deep fundamental theory at the root of maths and science!

I’m going to be writing more as it comes to my mind, kind of like what Derek Müller does on his second channel 2Veritasium. The bright side is that it’s going to be much easier for me. The downside is that there weren’t be as much quality.

In fact, this blog is going to be a bit messy, as I’ll talk about anything that comes to my mind, from travelling and sports to thoughts about education or the fundamental nature of mankind. If you guys really like it, I’ll eventually try to structure it more.

Best wishes,
Lê.
