Fourth gravitational wave signal detected – Five things you need to know

Fourth gravitational wave signal detected – Five things you need to know The latest observation was made on August 14, 2017. It’s the first gravitational wave signal recorded by the Virgo detector. New Delhi: Originally predicted in the early 20th century by Albert Einstein, gravitational waves – ripples in space and time – were not detected until 2015, when the Laser Interferometer Gravitational-wave Observatory (LIGO) identified the first such signal from two merging black holes. On Wednesday, scientists announced the detection of a fourth gravitational wave signal coming as a…

Kip Thorne co-writer of Nolan's Interstellar, awarded Nobel Prize for Physics

Kip Thorne co-writer of Nolan’s Interstellar, awarded Nobel Prize for Physics Kip Thorne : Oscar Awards snubbed science epic Interstellar and its co-writer Thorne. Nobel committee knows better than that. New Delhi: What has one of this year’s Nobel Prize winning physicist to do with making a Hollywood film a blockbuster? A lot, if you ask. While Oscars gave a royal snub to the writers and creators of Interstellar, Nobel Prize committee know better than. Before this Tuesday, Kip S Thorne, the 77-year-old American theoretical physicist whose work on gravitational…

Wave girls top Commerce, 99-41

Wave girls top Commerce, 99-41

Wave girls top Commerce, 99-41   A dominant, all-around performance powered Greenfield High School to a convincing 99-41 victory over High School of Commerce in an independent girls’ track & field meet Friday afternoon at the Pete Conway Track in Greenfield. Eighth-grader Victoria Marin won a pair of events for Greenfield (1-2), which won its first meet of the season. Marin took first in the 200 meters (29 seconds) and the long jump (15 feet, 11¾ inces), and coach Conway lauded her performance in the long jump which continues to…

Quantum tractor beam could tug atoms, molecules

Quantum tractor beam could tug atoms, moleculesdouble-slit experiment

Quantum tractor beam could tug atoms, molecules Electron beams could enable ‘matter wave’ treknology, theoretical study suggests The wavelike properties of quantum matter could lead to a scaled-down version of Star Trek technology. A new kind of tractor beam could use a beam of particles to reel in atoms or molecules, physicists propose in the May 5 Physical Review Letters. Scientists have previously created tractor beams using light or sound waves, which can pull small particles a few millimeters or centimeters (SN: 11/15/14, p. 16). But “the idea of doing…
