Canadian victory bond poster

A lithographed poster for Canadian victory bonds during World War I. Canada's contributions to World War I changed the country's history and enabled it to become more independent, while opening a deep rift between the French and English speaking populations. Battles such as Vimy Ridge, Second Battle of Passchendaele and the Battle of the Somme are still remembered today by anglophones as part of Canada's founding myth, to both its identity and culture.

Othello poster

Poster for an 1884 American production of William Shakespeare's Othello starring Thomas W. Keene. Because of its varied themes—racism, love, jealousy and betrayalOthello remains relevant to the present day and is often performed in professional and community theatres alike. The play has also been the basis for numerous operatic, film and literary adaptations. The production history of Othello has seen some landmark milestones: a 1660 performance was probably the first time a professional actress appeared on a public stage in England, and the 1943 production by Margaret Webster ran for 296 performances, almost twice as long as any other Shakespearean play on Broadway.

Voyager I approach to Jupiter

An animated view of Voyager I's approach to Jupiter. One frame of this image was taken each Jupiter day (approximately 10 hours) between January 6 and February 9, 1979, as the space probe flew from 58 million to 31 million kilometers from Jupiter during that time. The small, round, dark spots appearing in some frames are the shadows cast by the moons passing between Jupiter and the Sun, while the small, white flashes around the planet, are the moons themselves.

Reference ranges for blood tests by mass

Reference ranges for blood tests, sorted by mass concentration. A reference range is a set of values used by a health care provider to interpret a set of medical test results. The range is usually defined as the set of values 95 percent of the normal population falls within, or two standard deviations from the mean. All values (with some exceptions) denote blood plasma concentration, which is approximately 60–100% larger than the actual blood concentration if the amount inside red blood cells is negligible.

Storming of the Bastille

A hand-tinted French etching depicting the storming of the Bastille on 14 July 1789. The fall of the Bastille, along with the earlier Tennis Court Oath, is considered the beginning of the French Revolution, which deposed King Louis XVI and instituted the French First Republic.

Haile Selassie I of Ethiopia

Haile Selassie I was Ethiopia's regent from 1916 to 1930 and Emperor of Ethiopia from 1930 to 1974. The heir to a dynasty that traced its origins to the 13th century, and from there by tradition back to King Solomon and the Queen of Sheba, he is a defining figure in both Ethiopian and African history. Selassie is revered as the religious symbol for God incarnate among the Rastafari movement, whose name comes from Ras (literally "Head," an Ethiopian title equivalent to Duke), and Tafari Makonnen, Selassie's pre-coronation name.

Radar image of Venus

A radar image of the surface of Venus, centered at 180 degrees east longitude. This composite image was created from mapping by the Magellan probe, supplemented by data gathered by the Pioneer orbiter, with simulated hues based on color images recorded by Venera 13 and 14. No probe has been able to survive more than a few hours on Venus's surface, which is completely obscured by clouds, because the atmospheric pressure is some 90 times that of the Earth's, and its surface temperature is around 450 °C (842 °F).

Sea otter

A sea otter (Enhydra lutris) nurses her pup from nipples on her abdomen. Native to the coasts of the northern and eastern North Pacific Ocean, sea otters eat primarily invertebrates such as sea urchins and are among the smallest marine mammals. They are vulnerable to oil spills as their primary form of insulation is thick fur.

Atomic bomb schematic

Schematic representation of the two methods with which to assemble an atomic bomb. An A-bomb produces its explosive energy through nuclear fission reactions alone. A mass of fissile material (enriched uranium or plutonium) is assembled into a supercritical mass—the amount of material needed to start an exponentially growing nuclear chain reaction—either by shooting one piece of sub-critical material into another (the "gun" method, shown on top here), or by compressing a sub-critical sphere of material using chemical explosives to many times its original density (the "implosion" method, at bottom).

Night Watch

The Night Watch is one of the most famous works by the Dutch master Rembrandt. It was completed in 1642, at the peak of the Dutch Golden Age. The painting is renowned for three elements: its colossal size (363 x 437 cm, or 11 ft 10 in x 14 ft 4 in); the effective use of light and shadow; and the perception of motion in what would have been, traditionally, a static military portrait. It depicts a Schutterij (volunteer city guard) company being led by Captain Frans Banning Cocq (centre, with a red sash).
