This is beer day, here
So, I decided to share some information which would distract us all beer drinkers by concentrating more on the process of drinking and on drinking less (let’s be sure not to abuse any substance, even when it is pleasant/nice). A great/long paper about a well-documented book titled “A natural history of beer“, by George Scialabba.…

Quantum computing, let’s reduce weirdness
This is true. When we hear about Quantum Computing, we hear a lot of noise and so few useful information. But, after the all-too-usual “This revolution is going to blow everything”, you’ll find very little understandable talk. So, I was left collecting a few knowledge bits about this, that I would like to share with…

Fruits and vegetables in hospital
Normally, Magnetic Resonance Imaging (MRI) is interesting only the physicists for its uses in scientific research and the physicians for the fabulous pictures it gives of the insides of the human body. An MRI scanner will allow to display fine cuts of the body of the patient laid into the machine, but what is to…

High temperatures, low temperatures
Here, we don’t even speak about Summer or Winter; This is not about global warming either. The Rasmussen College presents us a great poster sweeping the widest possible range of temperatures to allow us to travel through universe’s thermal diversity. I hope they will sell the poster somewhere.

The Scale of the Universe
A nice Flash animation that you can play with to get a grasp of the dimensional diversity of our universe. Fly from portion of a yocto-meter to many yotta-meters.

Maglev trains: Toys and games
Magnetic levitation is considered by some as the future of train technology. Several real trains have actually been created (the German industry has been a pioneer and is in a strong competition with Japan for the development of such MagLev trains or Magnetic Levitation trains). But did you really see how it works? It’s easy.…

Surprise! You can find color in B&W photos
This is easy to reduce a color photo to a B&W image (any photo software or any B&W photocopier can do it). But the reverse operation seems difficult at best, impossible in most cases. However, a team of French scientists from the French INRIA (Guillaume Charpiat, Matthias Hofmann et Bernhard Schölkopf) presented recently an algorithm…
