Opticks is a book by English natural philosopher Isaac Newton that was published in English in 1704.[ (A scholarly Latin translation appeared in 1706.) The book analyzes the fundamental nature of light by means of the refraction of light with prisms and lenses, the diffraction of light by closely spaced sheets of glass, and the behaviour of color mixtures with spectral lights or pigment powders. It is considered one of the great works of science in history. Opticks was Newton's second major book on physical science.

At last, scientists have validated a key part of Einstein's general theory of relativity. The National Science Foundation, Caltech and MIT have confirmed the existence of gravitational waves, or ripples in spacetime. Their two LIGO (Laser Interferometer Gravitational-wave Observatory) detectors measured atomic-scale differences on September 14th, 2015 that point to the collision of black holes (also a new discovery) 1.3 billion years ago, triggering gravity ripples that only just reached Earth. There have long been hints of these waves, but hard evidence has proven elusive until now.
