The video below starts off with a long but useful review of conic constants and how planes ... or ellipses depending on the plane’s angle. As [Huygens Optics] explains, mirrors ground to each ...

In a paper published earlier this month in Physical Review Letters, a team of physicists led by Jonathan Richardson of the ...

In keeping with the ongoing optics-ready trend in the handgun world, Colt introduced two new models of its Competition 1911 ...

Qubits—the fundamental units of quantum information—drive entire tech sectors. Among them, superconducting qubits could be instrumental in building a large-scale quantum computer, but they rely on ...

The smooth wings of fruit-sucking moths appear to be ridged like a leaf – but the resemblance is created by nanostructures ...

Our brain and eyes can play tricks on us—not least when it comes to the expanding hole illusion. A new computational model ...

In the dense rainforests of northern Australia and South-East Asia, a master of disguise flutters through the shadows. The ...

Cardiac, vascular, and metabolic diseases continue to place a significant burden on global healthcare systems. This highlights the urgent need for ...

Optical illusions are fascinating brain teasers designed to trick the mind, making you second-guess what you see. They challenge how your brain interprets colours, shapes, and patterns ...

Optics and photonics is the study of the fundamental properties of light and harnessing them in practical applications. Optics and photonics covers the entire electromagnetic spectrum from high ...

We review basic principles of modern optical magnetometers, discuss fundamental limitations on their performance, and describe recently explored applications for dynamical measurements of ...
