Light is any wavelength of electromagnetic radiation, though the word is commonly used to refer to the visible light spectrum. The human eye typically perceives electromagnetic wavelengths between 400 and 700 nanometers, interpreting them as a range of colors from red to violet. Light is understood to exhibit both particle and wave properties, and the fundamental particle, or quantum, of light is called the photon. Who received the Nobel Prize in 1921 for his work on this wave-particle duality?
Sir Walter Scott
Back in the day
Herman Melville, inspired by his whaling experiences on the South Seas, penned Moby Dick, the now famed tale of a deranged whaling captain's obsessive voyage to find and destroy the great white whale to whom he lost his leg. The novel is at once an exciting sea story, a sociological critique of American prejudices, a repository of information about whaling, and a philosophical inquiry into the nature of good and evil. What may have inspired Melville to name his whale Moby-Dick?

Monet was a French painter who helped found the Impressionist movement in the late 19th century. His works include renowned en plein air, or outdoor, paintings, which capture natural landscapes with accents of sunlight and vibrant colors. He is also known for painting the same subject repeatedly, at different times of day and in different seasons, to show how changing light affects form. Where did Monet paint his famous Water Lilies series?
