These are quartz crystals and feldspar, so most sand in the world on the mainland is made of quartz crystal and feldspar. It's the erosion of granite rock.

While a quartz watch keeps time more accurately than the most finely crafted handmade mechanical Swiss watch, the value of a quartz watch has plummeted, while Swiss watches value has climbed into the stratosphere.

When you are in Britain you are not required to assimilate or become British for people to consider you one of them.

Furthermore, Saki poses unique therapeutic mud and Eupatoria has vast empty beaches with the purest sand.

The subject me and the object the scheme of things fuse into oneness, an experience nobody can say, I am denied of, an experience common to all and sundry.

The group gels. And it changes from a group of highly motivated but fairly individually centric people into something larger, into a tribe that becomes aware of its own existence.

These four drivers are fusing together and creating the big shift away from the 20th century, defined by hyper consumption, towards the 21st century, defined by collaborative consumption.

Quartz glass, which is common in cuvettes, can withstand high temperatures and is transparent in certain parts of the electromagnetic spectrum.

This complex primitive pattern has, however, been simplified to various degrees in the great majority of vertebrates, as bones have either fused or vanished entirely.

The duration that a star spends on the main sequence depends primarily on the amount of fuel it has to fuse and the rate at which it fuses that fuel, i.e.

The National Bureau of Standards (now NIST) based the time standard of the United States on quartz clocks from late 1929 until the 1960s, when it changed to atomic clocks.

Germanium differs from silicon in that the supply for germanium is limited by the availability of exploitable sources, while the supply of silicon is only limited by production capacity since silicon comes from ordinary sand or quartz.

In addition, the quartz watches also have integrated alarm, stopwatch, and timer functions that the other watches either lack, or that serve only as a design spoiling, hard to read effort to keep up with the competition.
