[time-nuts] Public lecture on atomic and optical clocks

[Ole Petter Ronningen]

Hello

There is a relatively recent (november 2015) public lecture by David
Wineland on Youtube, titled "Keeping Better Time: The Era of Optical Atomic
Clocks". I thought it an interesting, clear overview for the non-expert.

I searched the archives, but could not find it - apologies if this has
already been reported.
