Archaeologists have discovered numerous tools left behind by prehistoric civilizations. Most of these finds are made of stone, but in Spain, researchers have also found incredible weapons made of rock crystal.

A crystal radio is basically a high Q resonator tied to an antenna and an envelope detector. These days the envelope detector is a point contact diode such as a 1N34 Germanium diode. The resonant circuit passes a specific wavelength (or more specifically ...

There’s an old joke where a travel consultant asks a customer, “Are you interested in a world cruise?” The customer responds, “No, I’d rather go someplace else.” But if you’re interested in a five-month luxury journey that will take you to ...

Remember that old high school chemistry experiment where salt crystals precipitate out of a saltwater solution—or maybe the one where rock candy crystals form from sugar water? It turns out that your understanding of how crystals formed in those ...

If you’ve gone through a breakup, made a career change, or entered another transformative time in your life, chances are you had some support from the gang. Maybe your mom sent you a care package, your best ~corporate~ gal pal gave you a pre-interview ...

Swarovski isn't the only crystal worth seeking out at your favorite thrift store. Keep an eye out for valuable vintage pieces from this luxury glassmaker.

A stable honeycomb borophene layer hosts strongly interacting electrons that form a quantum liquid crystal state, with potential for superconducting electronics.

A team of US researchers has developed a tiny laser-based crystal sensor that can
