I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Scientists find new way to measure important beam property” Beam images as a function of solenoid strength. Credit: Jiahang Shao / Argonne National Laboratory For a wide variety of high-powered scientific instruments, from free-electron lasers to wakefield accelerators to electron microscopes, generating a bright electron beam that has specific properties represents one of the most…
“#A small number of self-organizing autonomous vehicles significantly increases traffic flow” With the addition of just a small number of autonomous vehicles (AVs) on the road, traffic flow can become faster, greener, and safer in the near future, a new study suggests. Dr. Amir Goldental and Prof. Ido Kanter, of Bar-Ilan University, present a simple…
“#Decorating windows for optimal sound transmission” In Applied Physics Letters, researchers discuss a layered glass material they developed that allows for efficient sound transmission with no air ventilation. This image is a view of the decorated window: The entire structure is made of glass, making it optically transparent. Credit: Xihan Tan Glass windows typically offer…
“#Why different measurements of material properties sometimes give different results” Credit: Vienna University of Technology It is very hard to take a photo of a hummingbird flapping its wings 50 times per second. The exposure time has to be much shorter than the characteristic time scale of the wing beat, otherwise you will only see…
“#Researchers investigate applications of magnetic sensors in the automotive and medical sectors” Further research goes into magnetic sensors and their future application. Credit: Dieter Suess et al. In his Christian Doppler Laboratory, Dieter Süss and his partners from the field of practice investigate the possible applications of magnetic sensors in the automotive and medical sector….
“#Demonstrating vortices as Brownian particles in turbulent flows” Flow structures with rotation. Snapshots of (A) the temperature θ and (B) streamlines originating from the lower thermal boundary layer. (C) Snapshots of Q/Qstd (Q-criterion) taken horizontally at the edge of thermal boundary layer for Ekman number (Ek) = 4 × 10−5 and Ra = 108 and…
“#Supernovae could enable the discovery of new Muonic physics” Artistic illustration of SN1987a. Credit: NRAO/AUI/NSF, B. Saxton. A supernova, the explosion of a white-dwarf or massive star, can create as much light as billions of normal stars. This transient astronomical phenomenon can occur at any point after a star has reached its final evolutionary stages….
“#Thermodynamics of computation: A quest to find the cost of running a Turing machine” A Turing Machine performing a computation over a sequence of steps. Credit: Kolchinksy and Wolpert, Turing machines were first proposed by British mathematician Alan Turing in 1936, and are a theoretical mathematical model of what it means for a system to…
“#Researchers uncover unusual glassy behavior in a disordered protein” Like a paper ball after crumpling, the disordered protein exhibited a slow relaxation, defying expectations. Credit: Pixabay/CC0 Public Domain When UC Santa Barbara materials scientist Omar Saleh and graduate student Ian Morgan sought to understand the mechanical behaviors of disordered proteins in the lab, they expected…
“#Beating noise via superposition of order” Credit: CC0 Public Domain Information can successfully be transmitted through noisy channels using quantum mechanics, according to new research from The University of Queensland and Griffith University. We all know it’s impossible to take a picture through thick smoke or fog—physicists would say, ‘it’s impossible to send information through…
