My name is Lê Nguyên Hoang. I am the founder of Science4All, which is a website where users can read and write quality popular science. I am an active author on Science4All, which has made me want to share much more than just science. In particular, I have a lot to say regarding education and travelling. And some other stuffs too.

On an education level, I am a PhD student in applied mathematics at the Ecole Polytechnique of Montreal. I work on mechanism design, somewhere between game theory and optimization. I have taught to undergrads at the university a course of calculus and a course of probability and statistics. And, as I said, I’m a popular science writer on Science4All.

On a travelling level, I was born in Vietnam, but grew up in France and now live in Canada. My favorite country is New Zealand where I spent 3 months. I have travelled across North America, Europe and South-East Asia. So far…

  1. Bonjour,
    Très content de lire tes articles.Vu ton profil, pourquoi pas des articles en Français aussi.
    Tu es du même pays que moi; mes enfants ne parlent plus le vietnamien.
    As-tu des restes du Viet Nam (culture, langue, etc…) ?

  2. Bonjour,
    Je suis ravi de voir que mes articles vous intéressent. Pour l’instant, je me concentre sur le développement de Science4All, qui est en anglais. Mais si l’opportunité se présente, cela me ferait plaisir d’écrire en français.
    Sinon, je parle un peu vietnamien. Et ce que je préfère du Viet Nam, c’est la nourriture. Em rất thích ăn phở!

  4. Dear Le,

    thanks for all your articles,

    and since you are writing about the magic of math …

    i would be very interested in an article from you , about the incredible works of Keith Critchlow, and the connections between – his discoveries in geometrycs and – your ideas in mathematics.

    Best regards,

    The Netherlands

  5. I cannot thank you enough for the video on weightlessness. I am an amateur struggling to understand the implications of general relativity, and I felt intuitively that the astronauts in the spacestation must be genuinely weightless. But so many apparently authoritative sources on the ‘net just provided the same old newtonian “falling makes you seem weightless” explanation, I was getting really confused. I now understand that they are in error in presuming that the Earth is the only valid frame of reference. Again, thank you – you are a first class educator.
