The Great Molasses Flood or the Boston Molasses Disaster, January 15th, 1919. Twenty one people were killed and 150 injured on Commercial Street in Boston's North End when a tank containing 2.3 million gallons of molasses ruptured and exploded. An eight foot wave of liquid moved down Commercial Street at a speed of 35mph. Wreckage of the collapsed tank is visible in background, center, next to a light colored warehouse.

James Clerk Maxwell (1831-1879), Scottish physicist whose major work was on light and electromagnetic waves. He showed that oscillating charges produced waves in an electromagnetic field, and that these waves had the same velocity as light. This led him to predict other forms of electromagnetic radiation, such as radio waves. His equations introduced the value c for the speed of light. He also worked on the motions of molecules in a gas, and showed that Saturn's rings must be composed of numerous particles.

Tsuki ni tomari fune. Sailboats moored under the moon. Print shows sailboats at dock and low buildings under the light of a full moon. Since ancient times the Japanese have contemplated the combination of snow, flowers, moon, and the beauties of nature. And not only have they contemplated such scenes, they've also made them favored themes for paintings and poetry. The symbolic meaning of the moon is closely tied to the act of rejuvenation.

A darkroom is a workshop used by photographers working with photographic film to make prints and carry out other associated tasks. It is a room that can be made completely dark to allow the processing of the light sensitive photographic materials, including film and photographic paper. Various equipment is used in the darkroom, including an enlarger, baths containing chemicals, and running water. Darkrooms have been created and used since the inception of photography in the early 19th century.

A camera obscura is an optical device that led to photography and the photographic camera. The device consists of a box or room with a hole in one side. Light from an external scene passes through the hole and strikes a surface inside, where it is reproduced, inverted (upside-down), but with color and perspective preserved. The image can be projected onto paper, and can then be traced to produce a highly accurate representation. Such cameras were later adapted by Joseph Nicephore Niepce, Louis Daguerre and William Fox Talbot for creating the first photographs. This image has been colorized.

Joseph Black (April 16, 1728 - December 6, 1799) was a Scottish physician and chemist, known for his discoveries of magnesium, latent heat, specific heat, and carbon dioxide. In 1750, while still a student, Black developed the analytical balance based on a light-weight beam balanced on a wedge-shaped fulcrum. Each arm carried a pan on which the sample or standard weights was placed.

Map showing the approximate locations of major coral reefs (red) and the general areas (whitened part) where reefs have suffered damage from bleaching. From 2014 to 2017, rising sea temperatures have caused the worst coral bleaching on record, with over 70 percent of reefs experiencing damage. When corals are stressed by changes in conditions such as temperature, light, or nutrients, they expel the symbiotic algae living in their tissues, causing them to turn completely white.

Inverted image. La dioptrique (Dioptrique, Optics, or Dioptrics), is a short treatise published in 1637 included in one of the Essays written with Discourse on the Method by Rene Descartes. In this essay Descartes uses various models to understand the properties of light. This essay is known as Descartes' greatest contribution to optics, as it is the first publication of the Law of Refraction.

Louis-Jacques-Mande Daguerre (November 18, 1787 - July 10, 1851) was a French artist and physicist and inventor of the daguerreotype process of photography. Although originally employed as a tax officer, Daguerre became a painter of opera scenery, and invented the illuminated diorama. After this he started work with Niepce on chemicals sensitive to light. Niepce died in 1833, but Daguerre continued their work, and unveiled his first camera, the Daguerreotype, in 1839.

The Kinetoscope is an early motion picture exhibition device designed for films to be viewed by one individual at a time through a peephole viewer window at the top of the device. The Kinetoscope was not a movie projector but introduced the basic approach that would become the standard for all cinematic projection before the advent of video, by creating the illusion of movement by conveying a strip of perforated film bearing sequential images over a light source with a high-speed shutter.

John Tyndall (August 2, 1820 - December 4, 1893) was an Irish physicist and medical educator. Beginning in the late 1850s, Tyndall studied the action of radiant energy on the constituents of air. He was the first to correctly measure the relative infrared absorptive powers of the gases nitrogen, oxygen, water vapor, carbon dioxide, ozone and methane.
