I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#New method to measure vibrational frequencies in molecular hydrogen ions” Credit: CC0 Public Domain An international research collaboration headed by VU-scientist Jeroen Koelemeij developed a new method to measure vibrational frequencies in the molecular hydrogen ion at four hundred times higher precision than before. The results improve the understanding of the fundamental laws of physics…
“#Shock waves might offer the jolt needed to reach Mars” A scramjet–which features an engine that uses an engine’s forward motion to compress incoming air, which flows at supersonic speeds. Credit: NASA, Tony Landis. Applying shockwaves can improve conditions for fluid mixing in supersonic combustion engines, paving the way for flights at speeds five times…
“#Cosmic tango between the very small and the very large” Tiny quantum fluctuations in the early universe explain two major mysteries about the large-scale structure of the universe, in a cosmic tango of the very small and the very large. A new study by researchers at Penn State used the theory of quantum loop gravity…
“#CERN experiment reports first evidence for ultra-rare process that could lead to new physics” The NA62 experiment is 270 metres long and includes a 120-metre-long vacuum tank, shown here, housing several of the particle detectors. (Note: the experiment axis is a straight line, the curving of the tank is an optical effect of the photo.)…
“#How microscopic scallops wander” Micro-hinge. Credit: Leiden University All microscopic objects, from enzymes to paint particles, are jittering constantly, bombarded by solvent particles: this is called Brownian motion. How does this motion change when the object is flexible instead of rigid? Ruben Verweij, Pepijn Moerman, and colleagues published the first measurements in Physical Review Research….
“#Argonne breaks ground on new state-of-the-art beamlines for the Advanced Photon Source” DOE Under Secretary for Science Paul Dabbar, third from left, joined leaders from Argonne, UChicago and the Department of Energy to break ground on the Long Beamline Building, part of the upgrade to the APS.

“#New ‘super light source’ should allow fascinating insights into atoms” GF concept: laser photons (pink waves) are scattered by PSI circulating in an accelerator ring. The scattered photons propagate in the direction of the ions motion (purple arrows) – resulting in an intense beam of highly energetic gamma rays. Credit: Universitaet Mainz The ‘Gamma Factory…
“#Ultracold mystery solved: Researchers crack a molecular disappearing act” Harvard researchers discover that ultracold temperatures slow chemical reactions to sluggish speeds, gifting them with a glimpse of how molecules transform and insights into the quantum world. Credit: Ni Lab/Harvard University In a famous parable, three blind men encounter an elephant for the first time. Each…
“#Physicists celebrate Japan collider record” University of Cincinnati physics professor Alan Schwartz points to a panel of optical-grade quartz in his optics lab. He and his students used these quartz panels to build a new detector for Japan’s SuperKEKB particle collider.
