World’s Most Accurate Clock

Those of you with even a passing interest in science will be aware of highly accurate atomic clocks. These types of clock use an atomic resonance frequency standard as their timekeeping element and are used to control things such as the frequency of television broadcasts and GPS systems.
In May 2009 the University of Colarado unveiled their strontium optical clock as being the world’s most accurate of it’s kind. Like other atomic clocks it harnesses the the natural and consistent vibration of atoms to keep track of time. What makes this particular clock different is that the vibration of these atoms is made even more consistent by holding them in a laser beam and then freezing them to a rather chilly -273 degrees (the temperature at which all matter stops resonating).
Even those this increase in accuracy is a minute fraction of a second, the implications of this development are large. It has great potential in areas of astrophysics and determining great distances, in particular measuring the distance to distant galaxies in space.
If it’s accuracy you are looking for in your designer watches then you should really look at quartz watches as mechanical watches are generally only accurate to -/+1 second per day, which will of course add up over the course of a year!
