[OM] Meet real precision

[Mike Gordon via olympus]

Some new configuration of ytterbium optical lattice clock it seems. 
Reproducible to the 10**-18 level and should be a tool to 
detect gravitational waves and probe for detection of dark matter--very cool.

Not exactly like my Grandmother's Tiffany never-wind which was an early battery 
powered torsion pendulum clock from early 1920's. I think I may have broken it 
as a kid trying to tinker with it. 
It was back impulsing so had to install a diode which I doubt is appropriate 
for the time.  Could never get it more accurate than 2-3 min/day and sent it to 
3 electrical horologists.  They could not do that much.  There apparently are 
just some problem clocks.  

No gravitational wave detection this month in South Hamilton, Mike
