Sir Isaac Newton published “Opticks” in  1704 — at the height of the “Age of Enlightenment”. For the first time he describes how  the inflexion of light becomes what we call color. Brilliant in its practicality, Opticks shows how beams of light bend through water and prisms, and why millions of drops of rain become magical rainbows. These wonderful illustrations have been locked inside books for centuries — now you can experience and share them in this STAKKUM theme.
