Georgia Tech Archivist Alison Reynolds and School of Physics astronomer and Georgia Tech Observatory director Jim Sowell lead a virtual discussion on Newton's Principia, which established the modern science of dynamics and serves as the basis for the modern study of physics, and Opticks, which provided our modern understanding of light and color.
By using time-lapse footage, along with a root-like robot to test ideas, researchers at Duke University and Georgia Tech gained new insights into how and why plant root tips twirl as they grow. The Georgia Tech researchers, all from the School of Physics, are Dan Goldman, Yasemin Ozkan-Aydin, and Mason Murray-Cooper.
A new study heralds the discovery of Gliese 486 b, an exoplanet in Earth's cosmic neighborhood with an atmosphere, which could help in the search for other primordial atmospheres around small rocky planets. The news has Inverse calling up a previous story on exoplanet research featuring Billy Quarles, a research scientist with Georgia Tech's Center for Relativistic Astrophysics.
Georgia Tech's Daniel Goldman gets credit here for the idea of using a certain plant root-mimicking robot for a study on molecular and mechanical strategies that roots have for navigating through soil. The School of Physics professor knew of the robot developed by UC-Santa Barbara's Elliott Hawkes, “and realized it would make a nice model of the real biological system,” Hawkes says. Goldman joined a team of Duke University researchers on the project.
Free electron lasers (FELs), which are driven by kilometer-long linear accelerators, emit bursts of short-wavelength light lasting one quadrillionth of a second. As a result, they can act as strobe lights for viewing the fastest events in nature — atomic or molecular motion — and therefore promise to revolutionize our understanding of almost any kind of matter. New research shows how to measure the super-short bursts of high-frequency light emitted from FELs.
Researchers from Georgia Tech have been conducting experiments designed to show the simplest of robots can still accomplish tasks. The team created a group of robots they call BOBbots, which stands for “behaving, organizing, buzzing bots.” One of the researchers in Dan Goldman, Dunn Family Professor in the School of Physics.
For the most part, animals don't get heart attacks — not even one of our closest living relatives, chimpanzees. Nonhuman animals experience other cardiac problems, but as far as scientists know, heart attacks are rare in other creatures. One of the scientists looking into this is Flavio Fenton, professor in the School of Physics, who has conducted extensive research into cardiac dynamics in humans and animals.
A team of researchers led by Dana Randall, ADVANCE Professor in the College of Computing, and Daniel Goldman, Dunn Family Professor in the School of Physics, sought to show that even the simplest of robots can still accomplish tasks well beyond the capabilities of one, or even a few, of them.
Researchers from Georgia Tech and the University of Tennessee–Knoxville uncovered hidden and unexpected quantum behavior in a rather simple iron-iodide material (FeI2) that was discovered almost a century ago.
A snake-like robot has been developed that can burrow through sand or loose soil. Researchers at the University of California Santa Barbara & Georgia Institute of Technology have taken their cues from plants & animals that have evolved to navigate subterranean spaces. They say they have "developed a fast, controllable soft robot that can burrow through sand.” The team is working on a project with NASA to develop burrowing for the moon or even more distant bodies, like Enceladus, a moon of Jupiter.
