Promising New Horizon 2010

I will use this blog to communicate about my personal research and developpement projects for efficient PDE solvers, geared toward structural mechanic. And also about other things, to show how my mind is like, if it as any importance...

At the begining my aim was to start a company to sell solvers using recent research findings and new developpement in hardware (multi-threaded and GPU computing).
But I finally gave up since I realized I wasn't tailored for such thing.

Shear waves, medecine and brain

Yesterday evening, too bored by what TV was proposing to me, I decided to watch a conference of Mathias Fink , a french researcher working on multidisciplinary application of waves. Specially shear waves. Here is a brief summary of his talk. In solids, waves have two principal components: compression waves (P-waves for primary) moving in the direction of propagation, and shear waves (S-waves, for secondary) that make ripples in the plane orthogonal to that direction. Since compression waves propagate in the direction of propagation, they move faster than shear waves. Usually ultrasound equipment in medicine only use compressional waves. But since human tissues have a high bulk modulus, the P-wave speed is relatively constant (around 1580 m/s). Human tissues are very stiff if you apply isotropic constraints on them (like pressure of water). However M. Fink and his colleagues proposed a new way to investigate human tissues by first sending a strong compressional wave in ...

Why Thinking is important

This week I went to the dentist for a routine check-up. By inspecting his waiting room I should have guessed that my dentist was a Jeovah witness. The book questioning the existence of pardise should have warned me. After a while the dentist came in and I sat in the scary chair with pipes and syringes all over. I looked at my wisdom teeth that I should remove because there is no place left for them in my mouth. I mean really no place, one is pushing against my jaw and it make a terrible infection. The dentist began to explain me that I should open my mind, that I should make some work upon myself and give a place to those teeth, that they were here for a REASON. It was not a matter of surgery, just a matter of faith and self opening to the world. Seeing that I was more and more sceptical, he mistakingly took the example of homepathy to explain me that OTHER WAYS exist. "Yeah, I replied, I know that. It's the placebo effect. But it work only if you believe it". At that p...
