Phys .org: Researchers use quantum mechanics to see objects without looking at them

Phys .org: Researchers use quantum mechanics to see objects without looking at them . “Imagine that you have a camera cartridge that might contain a roll of photographic film. The roll is so sensitive that coming into contact with even a single photon would destroy it. With our everyday classical means there is no way there’s no way to know whether there’s film in the cartridge, but in the quantum world it can be done.”

Hackaday: Inexpensive Reading Glasses Become Stereoscope

Hackaday: Inexpensive Reading Glasses Become Stereoscope. “It’s an unfortunate consequence of growing older, that no longer are you able to read the print on a SOT-23 package or solder a QFN without magnification. Your eyes inexorably start to fail, and to have any hope of continuing a set of reading glasses is required. We have this in common with [Niklas Roy], who noticed while shopping for cheap reading glasses that their lenses were of surprisingly good quality. The result of this observation was a stereoscope made from card and a few euros worth of eyewear.”

South China Morning Post: A stunning 16th-century Chinese ‘magic mirror’ was found in a US art museum after being tucked away in storage

South China Morning Post: A stunning 16th-century Chinese ‘magic mirror’ was found in a US art museum after being tucked away in storage. “Buddhist magic mirrors, also called ‘transparent’ and ‘light-penetrating’ mirrors, were first made in China during the Han dynasty (202 BCE–220 CE) and were also a notable artefact from Japan’s Edo period (1603–1867)….When the mirror is held to light from the correct angle, the bronze reflects the light to reveal the secret image, a buddha in the case of the Cincinnati Art Museum’s relic.”

Amateur Photographer: Brian May Reveals Plans For First International Stereoscopy Day

Amateur Photographer: Brian May Reveals Plans For First International Stereoscopy Day. “The event is planned to be a new international celebration of the birth of stereoscopic 3D. It will celebrate the inventor of stereoscopy, the British genius and polymath Sir Charles Wheatstone (who revealed his stereoscope in 1838), its early pioneers and their successors up to the present day.”

Scientific American: Light-Based Quantum Computer Exceeds Fastest Classical Supercomputers

Scientific American: Light-Based Quantum Computer Exceeds Fastest Classical Supercomputers. “For the first time, a quantum computer made from photons—particles of light—has outperformed even the fastest classical supercomputers. Physicists led by Chao-Yang Lu and Jian-Wei Pan of the University of Science and Technology of China (USTC) in Shanghai performed a technique called Gaussian boson sampling with their quantum computer, named Jiŭzhāng. The result, reported in the journal Science, was 76 detected photons—far above and beyond the previous record of five detected photons and the capabilities of classical supercomputers.”

Cornell Chronicle: Research reflects how AI sees through the looking glass

Cornell Chronicle: Research reflects how AI sees through the looking glass. “Things are different on the other side of the mirror. Text is backward. Clocks run counterclockwise. Cars drive on the wrong side of the road. Right hands become left hands. Intrigued by how reflection changes images in subtle and not-so-subtle ways, a team of Cornell researchers used artificial intelligence to investigate what sets originals apart from their reflections. Their algorithms learned to pick up on unexpected clues such as hair parts, gaze direction and, surprisingly, beards – findings with implications for training machine learning models and detecting faked images.”

Tarsier Goggles: a virtual reality tool for experiencing the optics of a dark-adapted primate visual system (Dartmouth Digital Commons)

Dartmouth Digital Commons: Tarsier Goggles: a virtual reality tool for experiencing the optics of a dark-adapted primate visual system . “Tarsier Goggles is a virtual reality (VR) project that allows everyone to experience how a tarsier might see. It serves as a tool to engage in hands-on scientific concepts in optics, perceptual science, and evolutionary biology, and also challenges our own thinking about our environment. The experience is self-guided and allows users to toggle between human and tarsier in order to explore different realistic environments with both sets of eyes. Built in Unity3D with SteamVR for the HTC Vive Pro. For various functionalities like teleportation, splash screens, and tooltips for our tutorial, we use Virtual Reality Toolkit (VRTK), an open source library.” Tarsiers are those primates with enormous eyes. MNN has a good overview.
