Henry Rumsey (July 7, 1784 – April 8, 1855) was an American judge and politician in the U.S. state of Michigan. He was a member of the Michigan Senate in its first term, and a portion of his farm became the campus of the University of Michigan.

The EMC effect is the surprising observation that the cross section for deep inelastic scattering from an atomic nucleus is different from that of the same number of free protons and neutrons (collectively referred to as nucleons). From this observation, it can be inferred that the quark momentum distributions in nucleons bound inside nuclei are different from those of free nucleons. This effect was first observed in 1983 at CERN by the European Muon Collaboration, hence the name "EMC effect". It was unexpected, since the average binding energy of protons and neutrons inside nuclei is insignificant when compared to the energy transferred in deep inelastic scattering reactions that probe quark distributions. While over 1000 scientific papers have been written on the topic and numerous hypotheses have been proposed, no definitive explanation for the cause of the effect has been confirmed. Determining the origin of the EMC effect is one of the major unsolved problems in the field of nuclear physics.

XI Brigade, Royal Horse Artillery was a brigade of the Royal Horse Artillery which existed in the early part of the 20th century. It was dissolved at the outbreak of World War I as its constituent batteries were posted to other formations.

Arthur Woody (April 1, 1884 - June 10, 1946) was born in Suches, Georgia. He was an American conservationist and humanitarian who saw his father kill the last deer in the North Georgia mountains in 1895, and is credited with bringing deer back to the North Georgia mountains. As a forest ranger for the United States Forest Service, he served in Georgia from 1912 to 1945 and was involved in the acquisition of land in what became the Chattahoochee National Forest. He also is known for putting rainbow and brown trout in streams, restoring native brook trout, restoring turkey and black bear populations and was the driving force behind Blue Ridge Wildlife Management Area (established 1936), the first of its kind in Georgia and the nation. He built lakes, fire towers, brought roads to the area, built Woody Gap School in Suches, Georgia (1940), was instrumental in building the Appalachian Trail through Georgia, and did much to help his mountain people during the Great Depression. Woody was known as the "Barefoot Ranger," "Kingfish," or simply "Ranger." He, along with "Ranger Nick" Nicholson of Clayton, Georgia, are considered to be the two most important early figures in the history of the Chattahoochee National Forest. Among the landmarks in the Chattahoochee National Forest honoring Woody is a trail through the Sosebee Cove, a 175-acre (0.71 km2) tract of prize hardwood that Woody purchased for the Forest Service that is now part of the Brasstown Ranger District.

The Battle of Yangcun was a battle during the march of Eight-Nation Alliance forces from Tianjin to Beijing during the Boxer Rebellion. The Alliance forces defeated the Qing and were able to continue their march towards Peking.

Gottfried Lumper (6 February 1747 – 8 March 1800 (Hefele says 1801)) was a German Benedictine patristic writer.

Sir John Anthony Pople (31 October 1925 – 15 March 2004) was a British theoretical chemist who was awarded the Nobel Prize in Chemistry with Walter Kohn in 1998 for his development of computational methods in quantum chemistry.
