Joan Eileen Annie Liversidge FSA was an English archaeologist who specialised in Roman Britain. Liversidge was an Honorary Keeper of the University Museum of Archaeology and Anthropology at the University of Cambridge, a research fellow at Newnham College, a faculty lecturer at Cambridge, she was a Founding Fellow of Cambridge. Her work was focussed on artistic evidence. Liversidge took a social history approach to Roman Britain, undervalued in subsequent decades; as with the undervaluing of her social history approach, her findings that several Roman villas in Britain were of more than one storey in height were overshadowed by assertions of R. G. Collingwood and Ian Richmond that such structures had only one story, but re-evaluations in 1982 found that such buildings could be of greater height, she was secretary of the Cambridge Antiquarian Society for 25 years. She was elected a fellow of the Society of Antiquaries of London in 1951. Furniture in Roman Britain. Tiranti, London, 1955. Britain in the Roman Empire.

Sprinting is running over a short distance in a limited period of time. It is used in many sports that incorporate running as a way of reaching a target or goal, or avoiding or catching an opponent. Human physiology dictates that a runner's near-top speed cannot be maintained for more than 30–35 seconds due to the depletion of phosphocreatine stores in muscles, secondarily to excessive metabolic acidosis as a result of anaerobic glycolysis. In athletics and track and field, sprints are races over short distances, they are among the oldest running competitions, being recorded at the Ancient Olympic Games. Three sprints are held at the modern Summer Olympics and outdoor World Championships: the 100 metres, 200 metres, 400 metres. At the professional level, sprinters begin the race by assuming a crouching position in the starting blocks before driving forward and moving into an upright position as the race progresses and momentum is gained; the set position differs depending on the start. The use of starting blocks allows the sprinter to perform an enhanced isometric preload.

Body alignment is of key importance in producing the optimal amount of force. Ideally the athlete should begin in a 4-point stance and drive forwards, pushing off using both legs for maximum force production. Athletes remain in the same lane on the running track throughout all sprinting events, with the sole exception of the 400 m indoors. Races up to 100 m are focused upon acceleration to an athlete's maximum speed. All sprints beyond this distance incorporate an element of endurance; the first 13 editions of the Ancient Olympic Games featured only one event—the stadion race, a sprinting race from one end of the stadium to the other. The Diaulos was a double-stadion race, c. 400 metres, introduced in the 14th Olympiad of the ancient Olympic Games. The modern sprinting events have their roots in races of imperial measurements which were altered to metric: the 100 m evolved from the 100-yard dash, the 200 m distance came from the furlong, the 400 m was the successor to the 440-yard dash or quarter-mile race.

Biological factors that determine a sprinter's potential include: The 60 metres is run indoors, on a straight section of an indoor athletic track. Since races at this distance can last around six or seven seconds, having good reflexes and thus getting off to a quick start is more vital in this race than any other; this is the distance required for a human to reach maximum speed and can be run with one breath. It is popular for testing in other sports; the world record in this event is held by American sprinter Christian Coleman with a time of 6.34 seconds. 60-metres is used as an outdoor distance by younger athletes. Note: Indoor distances are less standardized as many facilities run shorter or longer distances depending on available space. 60m is the championship distance. The 100 metres sprint takes place on one length of the home straight of a standard outdoor 400 m track; the world-record holder in this race is considered "the world's fastest man/woman." The current world record of 9.58 seconds is held by Usain Bolt of Jamaica and was set on 16 August 2009, at the 2009 World Athletics Championships.

The women's world record was set by Florence Griffith-Joyner. World class male sprinters need 41 to 50 strides to cover the whole 100 metres distances; the 200 metres begins on the curve of a standard track, ends on the home straight. The ability to "run a good bend" is key at the distance, as a well conditioned runner will be able to run 200 m in an average speed higher than their 100 m speed. Usain Bolt, ran 200 m in the world-record time of 19.19 sec, an average speed of 10.422 m/s, whereas he ran 100 m in the world-record time of 9.58 sec, an average speed of 10.438 m/s. Indoors, the race is run as one lap of the track, with only slower times than outdoors. A shorter race, the stadion, was the first recorded event at the ancient Olympic Games and the oldest known formal sports event in history; the world record in this event is 19.19 seconds, held by Usain Bolt and was set on 20 August 2009, at the 2009 World Athletics Championships. The 400 metres is one lap around the track on the inside lane.

Runners are staggered in their starting positions to ensure. While this event is classified as a sprint, there is more scope to use tactics in the race; the world record is held by Wayde van Niekerk with a time of 43.03 seconds in Rio Olympic 2016 in 400m final The 4×100 metres relay is another prestigious event, with an average speed, quicker than the 100 m, as the runners can start moving before they receive the baton. The world record in this event is 36.84 seconds, held by the Jamaican team as set 11 August 2012 at the Games of the XXX Olympiad held in London. The 4x400 metres relay is held at track and field meetings, is by tradition the final event at major championships; the event was a common event for most American students, because it was one of the standardized test events as part of the President's Award on Physical Fitness. The 50 metres is an uncommon alternative to the 60 metres. Donov

Sarah Frances Whiting, American physicist and astronomer, was the instructor to several astronomers, including Annie Jump Cannon. Whiting graduated from Ingham University in 1865. Whiting was appointed by Wellesley College president Henry Fowle Durant, one year after the College's 1875 opening, as its first professor of physics, she established its physics department and the undergraduate experimental physics lab at Wellesley, the second of its kind to be started in the country. At the request of Durant, she attended lectures at MIT given by Edward Charles Pickering, he invited Whiting to observe some of the new techniques being applied to astronomy, such as spectroscopy. In 1880, Whiting started teaching a course on Practical Astronomy at Wellesley. In 1895, as told by biographer Annie Jump Cannon, An exciting moment came when the Boston morning papers reported the discovery of the Rontgen or X-rays in 1895; the advanced students in physics of those days will always remember the zeal with which Miss Whiting set up an old Crookes tube and the delight when she obtained some of the first photographs taken in this country of coins within a purse and bones within the flesh.

Between 1896 and 1900, Whiting helped Wellesley College trustee Sarah Elizabeth Whitin to establish the Whitin Observatory, of which Whiting became the first director. Tufts College bestowed an honorary doctorate on Whiting in 1905, she was known for supporting prohibition. Whiting retired from Wellesley in 1916 and was a Professor Emeritus until her death in 1927 in Wilbraham, Massachusetts, she is buried in Machpelah Cemetery in New York, near her now-defunct alma mater. Whiting wrote textbook Daytime and evening exercises for schools and colleges, she was author of several articles in Popular Astronomy, including: "Use of Graphs in Teaching Astronomy", "Use of Drawings in Orthographic Projection and of Globes in Teaching Astronomy", "Spectroscopic Work for Classes in Astronomy","The Use of Photographs in Teaching Astronomy", "Partial Solar Eclipse, June 28, 1908", Solar Halos, "A Pedagogical Suggestion for Teachers of Astronomy", "Priceless Accessions to Whitin Observatory Wellesley College", "The Tulse Hill observatory diaries", "The Tulse Hill observatory diaries", as well as the obituary for Margaret Lindsay Huggins, "Lady Huggins".

Eric Clapton and the Powerhouse was a British blues rock studio group formed in 1966. They recorded three songs, which were released on the Elektra Records sampler album What's Shakin' in 1966. A possible fourth song remained unreleased; the Powerhouse was formed with full intention of being a short-lived studio project. In 1965 and 1966, American record producer Joe Boyd was in the process of opening a London office for Elektra Records and was looking for some British talent to feature on the first release from the label's local division, a sampler compilation album. Manfred Mann's singer Paul Jones suggested putting together an all-star band to mark the occasion; this band featured Jones playing harmonica alongside Eric Clapton on guitar and Manfred Mann's Jack Bruce on bass together with Steve Winwood on vocals and Pete York on drums, Ben Palmer on piano, who had played with Clapton and Jones as a member of the Roosters and the Glands. Ginger Baker was intended to fill the drummer's position, but he was unavailable at the time.

The Powerhouse only recorded a few songs in March 1966, three of which were released on the Elektra compilation album What's Shakin' alongside tracks by the Lovin' Spoonful, Al Kooper, Tom Rush and the Butterfield Blues Band. The album was reissued in the UK under the title Good Time Music; the tracks included were "Crossroads", "Steppin' Out" and "I Want to Know". There was a fourth song recorded, a "slow blues". "The slow blues was never issued, so they must have it on tape at Elektra somewhere", said Clapton in a March 1968 interview, printed in Guitar Player magazine in 1992. "It was pretty good, too."Due to contractual constraints, Winwood was credited as Steve Anglo in the original album's liner notes. It has been suggested that the song "I Want to Know" was in fact written by Jones under a pseudonym named for his wife, Sheila McLeod. Many members of the Powerhouse played together as members of other bands. Bruce and Clapton formed Cream in 1966 with Ginger Baker, Palmer joined them as their tour manager.

Clapton and Winwood have appeared together on numerous occasions, most notably from 1968-1969 as half of Blind Faith, with Ric Grech and again Ginger Baker. Since their original release the Powerhouse recordings have been re-released intermittently, with the band being credited differently depending on the release: "Crossroads" was included on Winwood's compilation album Winwood in 1971 credited to'Powerhouse'. Credited to'Eric Clapton and the Powerhouse'. Eric Clapton – guitar Steve Winwood – vocals Paul Jones – harmonica Jack Bruce – bass Pete York – drums Ben Palmer – piano
