John Woolman was an American merchant, tailor, journalist, Quaker preacher, and early abolitionist during the colonial era. Based in Mount Holly, near Philadelphia, he traveled through the American frontier to preach Quaker beliefs, and advocate against slavery and the slave trade, cruelty to animals, economic injustices and oppression, and conscription. Beginning in 1755 with the outbreak of the French and Indian War, he urged tax resistance to deny support to the colonial military. In 1772, Woolman traveled to England, where he urged Quakers to support abolition of slavery.
Soyuz 23 was an October, 1976, Soviet crewed space flight, the second to the Salyut 5 space station. Cosmonauts Vyacheslav Zudov and Valery Rozhdestvensky arrived at the station, but an equipment malfunction did not allow docking and the mission had to be aborted.
Nautilus was a submarine designed by Robert Fulton and first tested in 1800. Though preceded by Cornelis Drebbel's vessel of 1620 and the Turtle, Nautilus is often considered to be the first practical submarine.
RMS Empress of Ireland was a British-built ocean liner that sank near the mouth of the Saint Lawrence River in Canada following a collision in thick fog with the Norwegian collier Storstad in the early hours of 29 May 1914. Although the ship was equipped with watertight compartments and, in the aftermath of the Titanic disaster two years earlier, carried more than enough lifeboats for all aboard, she foundered in only 14 minutes. Of the 1,477 people on board, 1,012 died, making it the worst peacetime maritime disaster in Canadian history.
Ocean Ranger was a semi-submersible mobile offshore drilling unit that sank in Canadian waters on 15 February 1982. It was drilling an exploration well on the Grand Banks of Newfoundland, 267 kilometres (166 mi) east of St. John's, Newfoundland, for Mobil Oil of Canada, Ltd. (MOCAN) with 84 crew members on board when it sank. There were no survivors.
A submersible is an underwater craft which needs to be transported and supported by a surface vessel or platform. This distinguishes submersibles from submarines, which are self-supporting and capable of independent operation.
Xanthorrhoea is a genus of about 30 species of flowering plants endemic to Australia. Species are known by the name grass tree.
Battle Mountain is an igneous mountain in Rappahannock County, Virginia. The eastern slope is generally considered to reside in the unincorporated town of Amissville, Virginia while the western slope is generally considered to be within Castleton, Virginia. The entire mountain including the summit lies within private property at an elevation of 1,162 ft.
An ice spike is an ice formation, often in the shape of an inverted icicle, that projects upwards from the surface of a body of frozen water. Ice spikes created by natural processes on the surface of small bodies of frozen water have been reported for many decades, although their occurrence is quite rare. A mechanism for their formation, now known as the Bally–Dorsey model, was proposed in the early 20th century but this was not tested in the laboratory for many years. In recent years a number of photographs of natural ice spikes have appeared on the Internet as well as methods of producing them artificially by freezing distilled water in domestic refrigerators or freezers. This has allowed a small number of scientists to test the hypothesis in a laboratory setting and, although the experiments appear to confirm the validity of the Bally–Dorsey model, they have raised further questions about how natural ice spikes form, and more work remains to be done before the phenomenon is fully understood. Natural ice spikes can grow into shapes other than a classic spike shape, and have been variously reported as ice candles, ice towers or ice vases as there is no standard nomenclature for these other forms. One particularly unusual form takes the shape of an inverted pyramid.

The Mangala Valles are a complex system of criss-crossing channels on Mars, located in the Tharsis region and in the Memnonia quadrangle. They originated in the Hesperian and Amazonian epochs. They are thought to be an outflow channel system, carved by catastrophic floods, and the release of vast quantities of water across the Martian surface. This flooding was probably initiated by tectonic stretching and the formation of a graben, Mangala Fossa, at the channels' head, perhaps breaching a pressurized aquifer trapped beneath a thick "cryosphere" beneath the surface. The Mangala Valles contain several basins; after they filled, the overflow went through a series of spillways. One source of waters for the system was the Memonia Fossae, but water also probably came from a large basin centered at 40 degrees S.
A ballast tank is a compartment within a boat, ship or other floating structure that holds water, which is used as ballast to provide hydrostatic stability for a vessel, to reduce or control buoyancy, as in a submarine, to correct trim or list, to provide a more even load distribution along the hull to reduce structural hogging or sagging stresses, or to increase draft, as in a semi-submersible vessel or platform, or a SWATH, to improve seakeeping. Using water in a tank provides easier weight adjustment than the stone or iron ballast used in older vessels, and makes it easy for the crew to reduce a vessel's draft when it enters shallower water, by temporarily pumping out ballast. Airships use ballast tanks mainly to control buoyancy and correct trim.
The Red Seas is a series appearing in the British comics magazine 2000 AD, written by Ian Edginton and drawn by Steve Yeowell.
Zacatón is a thermal water-filled sinkhole belonging to the Zacatón system - a group of unusual karst features located in Aldama Municipality near the Sierra de Tamaulipas in the northeastern state of Tamaulipas, Mexico. It is the deepest known water-filled sinkhole in the world with a total depth of 339 meters (1,112 ft). The 392 meters (1,286 ft) deep Pozzo del Merro is deeper, but its nature as a near-vertical cave or a sinkhole still being debated.
The Watertower is a 1994 young adult's picture book written by Australian author Gary Crew and illustrated by Steven Woolman. The story, which takes place in a small rural town called Preston, is about two teenagers exploring a sinister watertower on Shooter's Hill. The illustrations for the watertower use a combination of chalk and pencil on black paper, and acrylic paint on textured board. The text is simple, while the complex illustrations create an eerie atmosphere, most notably with the recurring theme of the watertower symbol.
British Army Dirigible No 1, christened Nulli Secundus was a semi-rigid airship. First flown on 10 September 1907, it was Britain's first powered military aircraft.
The Johnson Sea Link accident was a June 1973 incident that claimed the lives of two divers. During a seemingly routine dive off Key West, the submersible Johnson Sea Link was trapped for over 24 hours in the wreckage of the destroyer USS Fred T. Berry, which had been sunk to create an artificial reef. Although the submersible was eventually recovered by the rescue vessel A.B. Wood II, two of the four occupants died of carbon dioxide poisoning: 31-year-old Edwin Clayton Link and 51-year-old diver Albert Dennison Stover. The submersible's pilot, Archibald "Jock" Menzies, and ichthyologist Robert Meek survived. Over the next two years, Edwin Link designed an unmanned Cabled Observation and Rescue Device (CORD) that could free a trapped submersible.

Mary Raphael Schenck Woolman was an American educator known for her advocacy of vocational education and consumer education, particularly for women. She was one of the first woman faculty members at Teachers College in New York City. She was the founder of Manhattan Trade School for Girls, the first vocational school for women in the United States. She was the author of several books and lectured around the country.
