Many crystals have signature shapes— like the cascade of pointed quartz or a pile of galena cubes. Every crystal's atoms have a defining feature: their organized, repeating pattern. The pattern isn't restricted to minerals- sand, ice, metals and DNA als
If you're not already familiar with liquid crystals, you might like to take a quick look at our main article on how LCDs work. But here's a very quick recap.As their name suggests, liquid crystals are a bit like solids in some respects and liquids in others. The ones we're ...
In some accelerometers, piezoelectric crystals such as quartz do the clever work. You have a crystal attached to a mass, so when the accelerometer moves, the mass squeezes the crystal and generates a tiny electric voltage.Artwork: The basic concept of a piezoelectric accelerometer: as the gray...

When water reaches freezing temps, ice crystals form around such dust particles. If no dust particles are present, then the ice won't form until the water gets even colder. In fact, research has shown that water can get down to about minus 40 degrees Celsius ( minus 40 degrees Fahrenheit...
" Science is essential to any work of science fiction; in fact, it separates science fiction from fantasy or other works of fiction. Furthermore, sci-fi fans are very discriminating. Sometimes, minor errors in the science do not detract from the story and may not be noticeable, except by ...
