Sometimes when you look into a swimming pool it’s difficult to tell how deep the water actually is. If you grab something long, like a stick, you can use it to test the depth of the water. Upon ...

Scientists have created a new class of laser beam that appears to violate long-held laws of light physics. These new beams, which the team calls “spacetime wave packets,” follow different rules of ...

For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays - without the need for artificially manufactured metamaterials. Scientists have long ...

Horiba has developed a particle size distribution measuring device that accurately measures particle size distribution even in the presence of similar-shaped particles. The device uses image ...

When the moon is completely enveloped by the Earth's shadow, yet glows with a mysterious dark red light—this astronomical ...

Building on the design of the original X5 Invisible Dive Case, the Dive Case Pro introduces advanced optics and a host of new ...

Microscopic crystals in tantalum disulfide have a starring role in what could become a hit for 3D displays, virtual reality and even self-driving vehicles. Microscopic crystals in tantalum disulfide ...

Imagine when the sun, Earth, and moon align in a nearly straight line; the Earth blocks the direct sunlight, causing the moon to enter the Earth's umbra. At this moment, the moon does not completely ...

IN preparing an elementary lecture on Light, intended to be given at the Taunton College School, I have had to consider how best to explain the somewhat abstruse principle of optical refraction. It is ...

Rainbows are optical phenomena resulting from the interaction of sunlight, water droplets, and the human visual system, not physical objects. Scientific understanding of rainbows developed over ...

HOUSTON - (Sept. 2, 2020) - Microscopic crystals in tantalum disulfide have a starring role in what could become a hit for 3D displays, virtual reality and even self-driving vehicles. A ...
