Physicist Claire Berger has been awarded the Chevalier dans L'ordre des Palmes Académiques for her groundbreaking graphene research — and her work on strengthening ties between U.S. and French scientists.
Physicists have developed a new model and clearer picture of molecular movements within active matter — bringing science a step closer to designing specific functions into new materials, and understanding emergent behaviors.
Researchers are exploring how active matter can be harnessed for tasks like designing new materials with tailored properties, understanding the behavior of biological organisms, and even developing new approaches to robotics and autonomous systems. But that’s only possible if scientists learn how the microscopic units making up active matter interact, and whether they can affect these interactions and thereby the collective properties of active matter on the macroscopic scale. School of Physics Professor Roman Grigorievand his research colleagues have found a potential first step by developing a new model of active matter that generated new insight into the physics of the problem. They detail their methods and results in a new study published in Science Advances, “Physically informed data-driven modeling of active nematics.” Lead author of the study is graduate researcher Matthew Golden. Co-authors are graduate researcher Jyothishraj Nambisan and Alberto Fernandez-Nieves, professor in the Department of Condensed Matter Physics at the University of Barcelona and a former associate professor of Physics at Georgia Tech. (This research was also covered in WorldTimeTodays andCityLife.)
There’s no artist more vibrant, spiritual, or creative than Mother Earth. Then, we have mortals like Georgia Tech School of Physics alumni Dylan Diamond, who execute Mother Earth’s designs into functional tools or, in this case, a timepiece: “Moss Clock.” The clock has its own gear train and servo, or motors. The bottom line: this technology is a clock composed of living moss. Diamond had the idea to make a “digitally inspired” clock where moving panels of different colored moss resemble a classic digital clock display. "My physics degree helped, but I firmly believe that in the age of information, with public access to so many free tutorials and teachers online, anyone can do something like this," Diamond said.
The science world is remembering W. Jason Morgan, who in 1967 developed the theory of plate tectonics — a framework that revolutionized the study of earthquakes, volcanoes and the slow, steady shift of the continents across the earth’s mantle. Morgan, who died July 31 at his home in Natick, Mass., attended Georgia Tech and received his B.S. from the School of Physics in 1955.
