These short anomaly-detection puzzles are designed to illustrate how reasoning often depends on identifying inconsistencies ...

People are increasing "chatfishing," using AI apps to generate texts to their romantic interests. Sometimes they'll slip up ...

SkyWave is a desktop application by InnovationForesight that uses AI-based wavefront sensing (AIWFS) to analyze telescope optics. You feed it a defocused star image ...

To many of you, Observable Space — formerly PlaneWave — needs no introduction. Starting as a breakaway from Celestron in southern California in 2006, PlaneWave was founded by Rick Hedrick and Joe ...

We present the development of a high-throughput, robotic GIWAXS platform for automated thin-film characterization at the ALS SAXS/WAXS beamline. The system features a UR5e robotic arm, a helium-purged ...

In my opinion, the Bahtinov mask is one of the most useful inventions for astrophotography. The traditional use of a Bahtinov mask is for focusing a telescope only and is not used for collimation of ...

Collimating is a method of aligning a light beam or stream of particles in a parallel path. The technique reduces particle distribution while ensuring parallel propagation. Collimation optics is the ...

Conventional spectroscopic ellipsometry is a powerful tool in optical metrology. However, when it comes to the characterization of non-periodic nanostructures or structured fields that are much ...

Optogenetics has brought transformational capabilities to neuroscience: the ability to not only measure but also manipulate the activity of neurons by light targeted at single neurons. This has ...

Quantum emitters radiate light omni-directionally, making it hard to collect and use the generated photons. Here, we propose a three-dimensional metal–dielectric parabolic antenna surrounding an ...
