8 February 17

Wearing orange and paisleys to celebrate "Opticks Day"! On this date in 1672 -- 345 years ago -- Isaac Newton read his first paper on the physical properties of light and lenses to the Royal Society in London. His full book Opticks: Or, a Treatise of the Reflexions, Refractions, Inflexions and Colours of Light was published in 1704. My tie has many reflexions, refractions, inflexions and colours.
