About this book

Written in English rather than Latin, and built from experiments a reader can follow one at a time, this is Newton's most approachable book. Published in 1704, it reports what he found by letting a beam of sunlight through a prism in a darkened room: white light is not pure but a mixture, and the colours are already present before the glass ever touches them. Newton moves on to the rings of colour in thin films, the bending of light at edges, and the rainbow, then closes with the Queries, a set of open questions about light, matter, and heat that kept physicists busy for the next two centuries. Free to read and download in PDF and EPUB.

About the author

Isaac Newton

Isaac Newton (1642-1727), English mathematician, physicist, and astronomer, spent his career at Cambridge before taking charge of the Royal Mint. Besides gravitation and calculus, he built the first reflecting telescope and worked for decades on light and colour, alongside private studies in alchemy and theology.
