Photography of the Invisible…

Topics: Applied Physics, Optics, Women in Science, X-rays In February 1896 Sarah Frances Whiting, founder of the physics and astronomy departments at Wellesley College, conducted a series of x-ray experiments. She was working only a few weeks after the public announcement of Wilhelm Röntgen’s discovery of the rays, and she was not alone; amateur andContinue reading “Photography of the Invisible…”

Bright, Tiny, Powerful…

Topics: Light-Emitting Diode, Nanotechnology, Solid-State Physics A new design for light-emitting diodes (LEDs) developed by a team including scientists at the National Institute of Standards and Technology (NIST) may hold the key to overcoming a long-standing limitation in the light sources’ efficiency. The concept, demonstrated with microscopic LEDs in the lab, achieves a dramatic increaseContinue reading “Bright, Tiny, Powerful…”

Neutrons Eye COVID…

Topics: COVID-19, High Energy Physics, Neutrons, Particle Physics Advanced neutron facilities such as the Institut Laue-Langevin are gearing up to enable a deeper understanding of the structural workings of SARS-CoV-2. The global scientific community has mobilized at an unprecedented rate in response to the COVID-19 pandemic, beyond just pharmaceutical and medical researchers. The world’s mostContinue reading “Neutrons Eye COVID…”

Strange Metals…

Topics: Black Holes, Modern Physics, Quantum Mechanics, Superconductors, Theoretical Physics Even by the standards of quantum physicists, strange metals are just plain odd. The materials are related to high-temperature superconductors and have surprising connections to the properties of black holes. Electrons in strange metals dissipate energy as fast as they’re allowed to under the lawsContinue reading “Strange Metals…”

Pig Slop…

Topics: Civics, Civil Rights, Existentialism, Fascism, Human Rights Farmers feed their pigs slop, a messy, wet mix of various leftovers—and when they do, they can say they slop the pigs. A derogatory way to talk about food that doesn’t look very tasty is to call it slop. And you can call sticky, overly sentimental music, writing, or films slop as well. Source:Continue reading “Pig Slop…”

Ceres…

Topics: Asteroids, Exoplanets, Space Exploration, Spaceflight “Ceres was the Roman goddess of agriculture, grain, and the love a mother bears for her child. She was the daughter of Saturn and Ops, the sister of Jupiter, and the mother of Proserpine. Ceres was a kind and benevolent goddess to the Romans and they had a common expression, “fit for Ceres,”Continue reading “Ceres…”

CdTe and IoT…

Topics: Alternate Energy, Internet of Things, Materials Science, Solar Power Photovoltaic cells made from cadmium telluride (CdTe) – already widely used in solar energy generation – also excel at harvesting ambient light indoors, making them an excellent energy source for the fast-growing Internet of Things (IoT). This is the finding of researchers at the MassachusettsContinue reading “CdTe and IoT…”

Quantum Hush…

Topics: Cryptography, Quantum Computer, Quantum Mechanics A “quantum secret sharing” scheme that allows 10 parties share information securely – the highest number so far – has been developed and demonstrated by researchers in South Africa. The protocol involves each party performing quantum operations on the photon without measuring its state and the team says it could helpContinue reading “Quantum Hush…”

Holographic Microscopy…

Topics: Holography, Microscopy, Optical Physics, Modern Physics ABSTRACT In the past few years, the venerable field of holographic microscopy has been revitalized by computational data analysis. It is now possible to fit a generative (forward) model of scattering directly to experimentally obtained holograms of complex microscopic objects. This approach enables precision measurements: it allows theContinue reading “Holographic Microscopy…”

Occam’s Razors and Scorched Earth…

Topics: Civics, Civil Rights, Existentialism, Fascism, Human Rights As Chancellor, Gerhard Schröder was a strong advocate of the Nord Stream pipeline project, which aims to supply Russian gas directly to Germany, thereby bypassing transit countries. At the time of the German parliamentary election, according to Rick Noak of The Washington Post: In 2005, Russian President Vladimir Putin’s friend SchroederContinue reading “Occam’s Razors and Scorched Earth…”
