Stanford bioengineers develop a 20-cent, hand-powered centrifuge


No comments. It is simply awesome. Perhaps, it is worth just to point you to Stanford University youtube channel, and to the actual scientific article on the paperfuge, as they called it, including its mathematical description.

  1. I used to make this toy with buttons when I was a kid! I perfectly recall the noise it makes when it goes fast enough.

    1. Wow... It is incredible! Anyhow, it is still too expensive. If the price comes down to 50 $, the washing machine companies would surely crash.

RSA Animate - Drive: the surprising truth about what motivates us - Daniel Pink

RSA Animate is a collection of 10 min cartoon-like animations on a whiteboard that partners with a synthesis of a conference given by renown academics in RSA Events . This series is put forward by the Royal Society of Arts (RSA), who aim at a 21st century enlightenment .  I first saw some of the short-film series while being in Cuba. I remember I was astonished by the amount of information they could compress in a 10 min talk. Then, I noticed that there was a great deal of post-processing after the 'natural' 30 min or so talk. Nonetheless, it is still amazing how they can manage to do it so smoothly. The animations deserve special attention. They are not only accompanying the talk but they actually supply complementary information, in terms of irony, cultural references, etc., while marking a step-by-step evolution of the speech in a better way than any slide show could do. Here is an RSA Animate example on "Drive: the surprising truth about what motivates us", ...

Slow science/publishing and educational system

Guys, I don't know if you already know about the ''Slow science movement'' or not, well this is a wiki definition for it: Slow science  is part of the broader  slow movement . It is based on the belief that  science  should be a slow, steady, methodical process, and that scientists should not be expected to provide "quick fixes" to society's problems. Slow science supports  curiosity -driven  scientific research  and opposes  performance targets . I'm personally interested in it if you remember Gabriel once we had a discussion on the waste of energy and resources to produce junk science and the fact that scientists are losing balance on looking into science.  Sometimes people do not know why they publish and for the sake of what?! it's become a tradition or kinda religion.  I'm most agreed with the directed scientific activities, slowly going ahead and touching the problem, whenever you can swallow the problem with...

Firing Line - Thomas Sowell with William F. Buckley, Jr. (1981)

Firing Line is a TV show from the US I discovered just a few days ago. It is always conducted by William F. Buckley, Jr. of whom it has been said to be  "arguably the most important public intellectual in the United States in the past half-century…".   The program is a talk show based upon the interview of top level intellectual figures from the US and abroad on different topics. It has the nice quality of being intellectually challenging while often dealing with highly polemic issues. See Hoover institution archives on Firing Line broadcasts for more features and details. In particular, the interview with Prof. Thomas Sowell in 1981 (entitled "The economic lot of minorities") contains a profound debate supported with lots of data on race and gender discrimination, and how unemployment and low income rates relate to education in ethnic minorities and women. I hope you reflect on these difficult points, which are still unresolved 36 years after this interview. ...
