Self Driving Microscopes to Make Discoveries on Their Own in the Future

Image: A smart approach to microscopy and imaging developed at Oak Ridge National Laboratory could drive discoveries in materials for future technologies. Credits: Adam Malin/ORNL, U.S. Dept. of Energy Microscopes are being taught to drive discoveries by researchers at the Department of Energy's Oak Ridge National Laboratory, using an intuitive algorithm developed at the lab's Center for Nanophase Materials Sciences that could lead to breakthroughs in new materials for energy technologies, sensing, and computing.  The method, described in Nature Machine Intelligence , combines physics and machine learning to automate microscopy experiments aimed at determining the functional features of materials at the nanoscale. “There are so many potential materials, some of which we cannot study at all with conventional tools, that need more efficient and systematic approaches to design and synthesize,” said Maxim Ziatdinov of ORNL’s Computational Sciences and Engineering Division and th

Memristor, a New Discovery Responsible for the Collision of Artificial Intelligence and Quantum Technology

Credits: Artificial intelligence has grown rapidly in recent years, with applications including speech recognition, image identification, medical diagnosis, and many others. Quantum technology, on the other hand, has been shown to be capable of computational power much beyond that of even the world's most powerful supercomputer. Physicists at the University of Vienna have now created a novel technology known as a quantum memristor that might allow these two worlds to collide, unlocking previously unimaginable capabilities. The experiment was carried out in partnership with the Italian National Research Council (CNR) and Politecnico di Milano on an integrated quantum processor that operates on single photons. The research was just published in the journal Nature Photonics . Neural networks are mathematical models that are at the heart of all artificial intelligence applications. The biological structure of the human brain, which is made up of linked nodes, inspire

The dance of Pendulums- Pendulum waves (Video)

The beauty of science and the conception of art. Pendulum Waves are a great example of a kinetics sculpture working on simple harmonics. Whats brilliant about these structures is that it runs on simple physics, that takes 15 balls and suspends them at different, well calculated lengths. The Pendulums are placed in increasing order of length of the pendulum, so while the longest completes 51 oscillations in 60 seconds, the shortest takes completes 65, producing a dance that is a visual delight. ENJOY!

Is the Earth's gravity same everywhere?

Earth's gravity measured by NASA's GRACE mission, showing deviations from the theoretical gravity of an idealized smooth Earth. (Photo credit: Wikipedia ) When you drop something, it falls downwards towards the ground. Why does it fall down? Why not up? All such questions were answered with a 7 lettered word-GRAVITY. Gravity is an attractive force and is stronger on Earth as compared to our Moon due to larger mass. When you drop an object it falls towards the ground and when it is dropped from a greater height it falls towards the ground with greater speed and impact. The greater impact and speed is attributed to acceleration (the rate of change of speed) which is higher due to gravity. The force of gravity is inversely proportional to the radius of the Earth , that's what our textbooks said in school. But a recent press release from the European Space Agency , showed that the shape of the Earth is not a perfect sphere but a geoid or ellipsoid, bulging slightly
