Top 5 Reasons Why Online Classes Suck
Too Many Distractions Photo by Ketut Subiyanto from Pexels.com The reason behind why students hate online classes is that they get distracted easily and turn their attention away from studying. There are countless distractions that can interrupt a student. Students have their cell phones and computers in their hands for online classes and just one…
Japanese Nobel-prize-winning semiconductor pioneer Isamu Akasaki dies aged 92
(from physicsworld.com) The Japanese semiconductor pioneer Isamu Akasaki has died at the age of 92. His work in the late 1980s and early 1990s led to the development of blue light-emitting diodes (LEDs), which soon found a wide range of applications from low-energy light bulbs and mobile-phone displays to televisions. For the work Akasaki shared the…
Online Learning Should Return to a Supporting Role
(from nytimes.com) As the coronavirus pandemic forces schools and college campuses to go online, the delivery model of education — largely unchanged for centuries — has suddenly been disrupted. This may seem like the acceleration of a permanent shift toward online learning, but I have my doubts. In fact, economics tells us that technology will…
Gravity: We might have been getting it wrong this whole time
(From phys.org) Symmetry has been one of the guiding principles in physicists’ search for fundamental laws of nature. What does it mean that laws of nature have symmetry? It means that laws look the same before and after an operation, similar to a mirror reflection, the same but right is now left in the reflection.…
In surprise breakthrough, scientists create quantum states in everyday electronics
(From phys.org) After decades of miniaturization, the electronic components we’ve relied on for computers and modern technologies are now starting to reach fundamental limits. Faced with this challenge, engineers and scientists around the world are turning toward a radically new paradigm: quantum information technologies. Quantum technology, which harnesses the strange rules that govern particles at…
An artificial intelligence algorithm can learn the laws of quantum mechanics
(From techxplore.com) Artificial intelligence can be used to predict molecular wave functions and the electronic properties of molecules. This innovative AI method developed by a team of researchers at the University of Warwick, the Technical University of Berlin and the University of Luxembourg, could be used to speed-up the design of drug molecules or new…
Beyond Einstein: Physicists solve mystery surrounding photon momentum
(From phys.org) Albert Einstein received the Nobel Prize for explaining the photoelectric effect: in its most intuitive form, a single atom is irradiated with light. According to Einstein, light consists of particles (photons) that transfer only quantised energy to the electron of the atom. If the photon’s energy is sufficient, it knocks the electrons out…
SwarmTouch: A tactile interaction strategy for human-swarm communication
(From phys.org) Researchers at the Skolkovo Institute of Science and Technology (Skoltech) in Russia have recently introduced a new strategy to enhance interactions between humans and robotic swarms, called SwarmTouch. This strategy, presented in a paper pre-published on arXiv, allows a human operator to communicate with a swarm of nano-quadrotor drones and guide their formation,…
Dog-like robot jumps, flips and trots
(From phys.org) Putting their own twist on robots that amble through complicated landscapes, the Stanford Student Robotics club’s Extreme Mobility team has developed a four-legged robot that is not only capable of performing acrobatic tricks and traversing challenging terrain but is also designed with reproducibility in mind. Anyone who wants their own version of the…
