He competed in the men's middleweight event at the 1952 Summer Olympics. |
Tris(cyanoethyl)phosphine |
Tris(cyanoethyl)phosphine is the organophosphorus compound with the formula P(CHCHCN). |
It is white solid that is air stable, which is unusual for a trialkylphosphine. |
It is prepared by the hydrophosphination of acrylonitrile with phosphine. |
The compound has been the subject of much research. |
For example, it is an effective reagent for the desulfurization of organic disulfides. |
Carole Ann Haswell |
Carole Ann Haswell is a British astrophysicist and current Professor of Astrophysics and Head of Astronomy at the Open University. |
She is a Fellow of the Royal Astronomical Society. |
She has been involved in the detection of several exoplanets, including Barnard's Star b. |
Haswell was born in Saltburn-by-the-Sea, North Yorkshire, and grew up in Dormanstown. |
Her father worked on an ammonia recovery plant at Imperial Chemical Industries. |
She became interested in space as a child, when her father told her about the Apollo astronauts as they gazed at the moon while on Redcar beach. |
Although she originally wanted to be an astronaut, she realised at the age of ten that this was impractical. |
She attended Huntcliff School where she worked towards her GCE Ordinary Levels. |
Whilst a student at Prior Pursglove and Stockton Sixth Form College, Haswell was interested in art, mathematics and physics, and was a fan of the television show "Star Trek". |
One of her physics teachers was rumoured to be biased against girls, and despite Haswell achieving the highest grades possible in her A-level exams, refused to write her a reference to study physics at university. |
She eventually studied mathematics at the University of Oxford, but wanted to apply mathematics to the real world and became tired of abstract proofs. |
Haswell eventually spoke to Donald Blackwell who helped her transfer courses, and enrolled on a physics degree at University College, Oxford. |
During her time as an undergraduate student, Haswell was President of the Oxford University Astronomical Society and rowed in the Summer Eights. |
Haswell earned her doctorate at the University of Texas at Austin, where she worked on black hole binaries. |
She attended the Hubble Space Telescope launch in 1990. |
She later joined the Space Telescope Science Institute, where she worked on accretion flow and multi-wavelength observations. |
In 1994, Haswell moved to Columbia University, where she worked on black hole X-ray transients and cataclysmic variable stars. |
She was made a lecturer at the Barnard College where one of her students was Lauryn Hill. |
Haswell moved back to the United Kingdom in 1996 and was made a lecturer at the University of Sussex. |
Since 1999, she has been at the Open University, at first still working working on black holes and accreting binary stars and switching to exoplanet research in 2003. |
Early work on exoplanets was not well funded, and Haswell has spoken about using second hand Canon camera lenses to make suitable telescopes. |
First working on accreting binary stars, and then exoplanets. |
In particular, Haswell studies short period exoplanets. |
Since 2012 she has led the "Dispersed Matter Planet Project", which involves the analysis of light from nearby stars to identify which host mass-losing planets. |
In 2018 Haswell was part of the team that was first to identify a planet around Barnard's Star, the closest single (non-binary) star to Earth, a red dwarf star that is six light years away from Earth. |
Using the radial velocity method, the team discovered Barnard's Star b. |
The solar system around Barnard's Star touches on the edge of the Oort cloud. |
Barnard's Star b has a mass three times that of Earth and orbits Barnard's Star in 233 days. |
Haswell has predicted that the planet may have a similar surface temperature to Europa. |
In 2019 Haswell used the High Accuracy Radial Velocity Planet Searcher (HARPS) to discover six extraordinarily hot exoplanets (with surface temperatures between 1100 and 1800 °C). |
At temperatures this high the atmosphere and surface levels of the planet can be lost, and the materials disperse into a thin sheet of gas. |
The gas filters the light from nearby stars, which allowed Haswell and colleagues to study the chemical composition of the atmosphere of the gas sheet. |
The planets have masses equivalent to 2.6 times the mass of the Earth with almost half the mass of Jupiter. |
Haswell has proposed that these planets could be used to understand the geology of the rocky planets in Earth's solar system. |
She is part of the team for CHaracterising ExOPlanets Satellite (CHEOPS), which will examine known exoplanets to improve our understanding of their sizes. |
CHEOPS, which features a 35 cm telescope, launched in December 2019. |
Haswell has been featured in a Royal Astronomical Society exhibition on women fellows. |
She regularly provides expert opinion to the national media and is involved with various outreach programmes through the International Astronomical Union. |
Haswell was awarded the Open University Outreach and Public Engagement Award for her work targeted at people with low science capital in Teesside. |
Haswell has a daughter. |
She is interested in the stock market and has used her understanding of astrophysics to buy and sell stocks. |
Haswell's publications include: |
Oldknows Factory, Nottingham |
The Oldknows Factory is a former lace factory on St Ann's Hill Road, in the city of Nottingham in England. |
The factory is formed of two 18th century factories, which have since been joined. |
The original purpose of both factories was the manufacture of lace. |
It's since been converted to house artist studios, workshops, and offices to rent. |
The original structure remains as a Grade II-listed building. |
Lata Brandisová |
Countess Marie Immaculata Brandisová, also known as Lata Brandisová or Lata von Brandis, (26 June 1895 – 12 May 1981) was a Czech equestrian and the only woman to win the Great Pardubice Steeplechase. |
Her victory over the Nazi officers at the 1937 race, seen as a symbol of Czech resistance against Nazi Germany, was celebrated with parades attended by thousands of people. |
She is the subject of Richard Askwith's book "Unbreakable: The Woman Who Defied The Nazis In The World’s Most Dangerous Horse Race". |
Brandisová was born on 26 June 1895 at Schäffer Castle in Úmonín, Austria-Hungary (now the Czech Republic) to Count Leopold von Brandis and Johanna von Schäffer. |
She was a member of an old Tyrolean family that had been ennobled in 1580, but later became impoverished. |
Her father, a horse breeder, had served as a lieutenant colonel in the Austrian army. |
Her mother was the daughter of Christian Ritter von Schäffer. |
Her paternal grandmother, Countess Barbara Kinská, was the sister of Count Oktavian Kinsky, who was one of the founders of the Great Pardubice Steeplechase. |
She had a twin sister, Countess Marie Kristýna Brandisová. |
In 1897 they moved from Schäffer Castle to a chateau in Řitka owned by her mother. |
Brandisová began horseback riding when she was eight years old and grew up attending horse races with her father. |
In 1916, at the age of 21, she competed in her first horse race. |
During the First World War, her father and brother, Count Nicholas von Brandis, went off to fight. |
Her brother was killed in action in Italy. |
Much of their property was seized y the government during the war. |
After the establishment of Czechoslovakia, the family lost much of their remaining property. |
She continued her training at the Prague-Velká Chuchle Racecourse and, in 1921, won her first women's race. |
In 1926 her cousin Count Zdenko Radslav Kinský, a nephew of Oktavian, invited her to Orlík Castle to breed Kinsky horses for hurdle racing. |
She continued to train as a horse racer at Velká Churchle and Veveří Castle under the coaching of Karel Šmejda. |
In 1927 she signed up to race in the Great Pardubice Steeplechase. |
Her enlistment in the race caused controversy, and she was faced with protests as the race was seen as too dangerous for a woman. |
Petitions were made to the Czechoslovak Jockey Club to have Brandisová removed from the race. |
The Jockey Club decided that she would be allowed to race, following advice from the Royal Jockey Club in Great Britain. |
The Great Pardubice of 1927 was the first time a woman raced, and the first time a French rider raced (Count Alexandre de la Forest). |
Brandisová placed fifth, after falling three times on the race track. |
In 1933 she raced in the Great Pardubice on a mare named Norma and placed third. |
A year later she placed second, and in 1935 she placed fifth. |
In 1937 she raced with Norma in the 56th Great Pardubice. |
At this time, there was extreme tension between Czechoslovakia and the neighboring Nazi Germany, with the Czechs fearing an invasion. |
Over 40,000 people attended the race, hoping to see a Czech jockey defeat the Germans, who had been consecutive champions in the Great Pardubice over the last few years. |
On 17 October 1937, Brandisová became the first woman to win the race, seven lengths ahead of a German rider. |
Celebrations culminated with a 10,000 person parade from the racecourse to town square in Pardubice. |
The race was not held again until after World War II. |
Germany invaded Czechoslavkia in 1939, and Brandisová's estate was seized by the Nazi government. |
During the war, she joined the Czech Resistance, providing food for resistance fighters and tending to wounded soldiers during the Liberation of Prague. |
After the war, Brandisová raced again in the Grand Parduice, failing to finish in 1947. |
After the Soviet invasion of Czechoslovakia in 1948, she and her sisters moved into cottage in the woods, where they lived in relative poverty throughout the Communist regime. |
She died from pneumonia in Reiteregg, Austria on 12 May 1981. |
