Enter this guide by [Mithuna] from Looking Glass Universe, where she circles back on the concept of measurement basis in quantum mechanics using a rather simple piece of calcite crystal.

One of Earth's most abundant minerals, calcite is a major component of limestone and marble. It is also the most stable of the three common, naturally occurring crystal forms of calcium carbonate ...

A chemical analysis confirmed that the stone was Icelandic Spar, or calcite crystal, believed to be the Vikings' mineral of choice for their fabled sunstones, mentioned in the 13th-century Viking ...

This review focuses on the effect of water on the binding conformation of an organic molecule at a hydrated calcite crystal surface. A recent molecular dynamics simulation suggested that water ...

Hilton, with Dr. Harry Berman, a mineralogist from Harvard, had discovered the “optical” calcite, a common crystal deposited in veins in the desert’s sandstone. This high-grade calcite ...

The calcite crystals are imaged to simultaneously visualize the crystal morphology and internal strain fields. Our data reveal that each crystal possesses a single dislocation loop that occupies a ...

A sixteen-foot long calcite crystal is known in Iceland. Fluorite (calcium-fluoride) crystals can also get big. A cubic crystal with a diameter of 6.5-foot was found in New Mexico, U.S. During ...

Harry Potter and Bilbo Baggins, take note: Scientists are a step closer to conquering the "magic" of invisibility. Many earlier cloaking systems turned objects "invisible" only under wavelengths ...
