Here are some more unsung heroes of research: scanners (the human kind). In the 1950s, Donald Glaser invented the bubble chamber – a way to track infinitesimally small quantum particles as they winked in and out of existence. The idea – which may or may not have been tested in beer – was to create…

Today’s guest post is by Weizmann Institute physicist, Prof. Micha Berkooz. Berkooz, a string theorist, recently organized a conference at the Institute on “Black Holes and Quantum Information Theory.” We asked him about Hawking’s recent proposal, reported in Nature under the headline:”There are no black holes.”   Celebrated theoretical physicist Stephen Hawking has opened a…

Breaking the Law

A recent paper by Weizmann Institute scientists suggests that we might be able to break the third law of thermodynamics. This is how that law was originally formulated in 1908 by Walther Nernst: “It is impossible for any procedure to lead to the isotherm T = 0 in a finite number of steps,” (source: Wikipedia).…

Physical Benefits

Of the four new articles online on our website, three happen, purely by accident, to be on physics research. The three are very different, and yet each is an illustration of the ways that basic physics research changes our world – in small and large, practical and enlightening ways. And each is situated at a…

Today’s post is about some cool chemistry – very cool. About 0.01°Kelvin, as a matter of fact (that is, one hundredth of a degree above absolute zero). Physics experiments conducted at such temperatures are already old hat, but chemistry is another story, altogether. Scientists have been attempting to produce chemical reactions at ultra-low temperatures for…

Science magazine seemed to imply there was some grousing about the new Fundamental Physics Prizes awarded by billionaire Yuri Milner, but we in Rehovot think it’s a good thing. While one can quibble about which fields are still underfunded, we believe that any support for truly basic research — the kind whose applications, if they…

This week’s Weizmann news stories: A “steam release valve” for inflammation, a “brake” for cell division and an “amplifier” for quantum signals. The steam release valve mechanism also involves an amplifier – one that ramps up the inflammation signal in response to viral attack on a cell. When the signal reaches its peak, it trips…
