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…”

Quantum Dots and Diffusion…

Topics: Biology, Diffusion, Quantum Dots, Quantum Mechanics Quantum dots diffuse within living cells in a nearly two-dimensional fashion. This result, which was obtained using a new 3D microscopy technique that can track single particles, sheds fresh light on intracellular diffusion – a process that is critical for moving molecules around the cell and for mediatingContinue reading “Quantum Dots and Diffusion…”

Blind Mice Seeing…

Topics: Bioengineering, Optical Physics, Nanorods, Nanotechnology Even in the dark, rattlesnakes and their fellow pit vipers can strike accurately at small warm-blooded prey from a meter away. Those snakes, and a few others, can see in the IR—but not with their eyes. Rather, they have a pair of specialized sensory organs, called pit organs, locatedContinue reading “Blind Mice Seeing…”

Lingering Effects…

Topics: COVID-19, Coronavirus, Pandemic I have friends who insist on seeing their friends during a pandemic, playing the equivalent of Russian Roulette (apropos, as they are capitalizing on our hubris), flaunting safety concerns and wearing masks “when they think about it” and selectively reading any materials I might send them. Well, I’ve attended at leastContinue reading “Lingering Effects…”

Gaming This Out…

Because of the recent changes in my previous platform, I am discontinuing https://www.physics4thecool.blogspot.com and continuing on WordPress. What follows is the post I meant for Blogger. I will miss it.
