When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of ...

Smartphone sensors and microphones are not exactly designed to be used as measuring tools. Also, the quality of these ...

This is a subject close to my own heart - I was slightly involved in an earlier iteration of very similar research. The aim is to find out how rich or poor people are in remote or otherwise ...

Human vision relies on light. After reflecting off surfaces, light enters into the eyes and travels through the cornea and pupil to produce an image on the retina. The eye is sensitive to a broad ...

A new method will help with discovering the most efficient lamps, which may save billions in lighting costs in the future. The method helps discovering the most efficient lamps, which may save ...

Researchers are seeing the light, but in an altogether different way. And how they are doing it just might be the semiconductor industry's ticket for extending its use of optical microscopes to ...

Laser Doppler vibrometers (LDVs) measure vibrations in ways that other sensors can't. From large aircraft structures to microscopic MEMS sensors, and Laser Doppler vibrometers (LDVs) measure ...

The fact that so many people are stuck at home makes for strange opportunities. Italy’s confined populace has taken to singing from the balconies — and now researchers are asking them to use those ...

In the last few weeks I've been working on a slightly more formal version of this post on black-body radiation for use in something else. One of the tricky things in writing about the development of ...

How does one go about measuring the amount of light in a given area? With a Light Meter of course! Maintaining proper lighting levels can be very important in places like schools, hospitals and even ...
