New research clarifies how toroidal droplets—which initially take the shape of a donut—evolve into spherical droplets by collapsing into themselves or breaking up into smaller droplets. Work with droplets has implications for the life sciences, and could improve industrial processes....“Surface tension drives the evolution of the droplets,” says Alexandros Fragkopoulos, a PhD candidate at Georgia Institute of Technology.
More than ten years ago, astronomers made a discovery that has puzzled them ever since – supermassive black holes appeared to have popped up soon after the start of the Universe. It is thought to take billions of years for supermassive black holes to form, but at least 20 of them were spotted at the dawn of the Universe, just 800 million years after the Big Bang. A team of researchers from Dublin City University, Columbia University, Georgia Tech, and the University of Helsinki, have now used computer simulations to attempt to solve the mystery. The results say a black hole can grow quickly
It’s no secret that supermassive black holes are heartless beasts: These objects of immense gravity that let nothing, not even light escape, have fascinated astronomers since the early 20th century.
Bright radiation emitted by neighboring galaxies likely fueled the rapid growth of supermassive black holes in the early universe, a new study shows. John Wise, an associate professor in the School of Physics, is a co-author of the study.
To explore the mathematical possibilities of alternative geometries, mathematicians imagine such ‘non-Euclidean’ spaces, where parallel lines can intersect or veer apart.
Imagine a liquid that could move on its own without human effort or the pull of gravity. You could put it in a container flat on a table, not touch it in any way, and it would still flow. As reported in Science, researchers have taken the first step in creating a self-propelling liquid. The finding offers the promise of developing an entirely new class of fluids that can flow without human or mechanical effort.
It's Vice's turn to have fun with a new study on mammal defecation provided by School of Biological Sciences associate professor David L. Hu's lab. The study found that despite a wide range of sizes in bodies and feces, most healthy mammals poop at the same rate.
Science Daily picked up the Georgia Tech news story about the ethene-to-graphene research study, which included two members of the School of Physics' Center for Computational Materials Science: Bokwon Yoon, a research scientist, and professor Uzi Landman, who is also CCMS director.
