most perfect sphere on Earth. Made from a single crystal of silicon 28 atoms, the object has been created by the Avogadro Project to help solve the
longest running problem in measurement - how to define the kilogram.
Silicon is extremely stable though, and as they now have extremely accurate measurements for that isotope, this is actually a much better way of
dictating the standard of our made up system of measurements.
I wonder if there are any experiments that you can utilize that damn near perfect sphere for.
This doesn't sound right. I thought the spheres that made up the gyroscopes for the Gravity Probe - B experiment are actually the roundest objects
ever made on Earth? These were made from quartz with a layer of Niobium.
As an aside, I find that reseacher girl very attractive.
ETA: Also, we need to start teaching and using the metric system in the U.S. We use it all the time in the lab.
