Jan 19, 2021... We have been measuring time for millennia. Prof. Roee Ozeri of the Department of Physics of Complex Systems and Institute Vice President, provides an engaging history of these efforts, their inspiration, and their efficacy, from the sundial to the pendulum to modern atomic clocks.
Dec 29, 2020... Quantum mechanics, the theory that describes the physics of the universe at very small scales, is notorious for defying common sense. Consider, for instance, the way that standard interpretations of the theory suggest change occurs in the quantum turf: shifts from one state to another supposedly happen unpredictably and instantaneously. Put another way, if events in our familiar world unfolded similarly to those within atoms, we would expect to routinely see batter becoming a fully baked cake without passing through any intermediate steps. Everyday experience, of course, tells us this is not the case, but for the less accessible microscopic realm, the true nature of such “quantum jumps” has been a major unsolved problem in physics.

REHOVOT, ISRAEL—January 12, 2021—In the not-so-distant past, the discovery of a supernova—or exploding star—was considered a rare occasion.
When Prof. Avishay Gal-Yam of the Weizmann Institute’s Particle Physics and Astrophysics Department was a doctoral student, he only located seven supernovas over the course of four years. But today, advanced measuring instruments and analytical methods make it possible to detect fifty such explosions daily. While these improved means may have made these celestial events somewhat less notable over the years, the greater number of observations has also increased the probability that researchers will spot rarer types of explosions that have so far existed only as theoretical constructs. Gal-Yam and his colleagues recently discovered a rare-type supernova that has never been observed before. Their findings are being published today in Nature.
