Dictionary of Scientific Biography

The Dictionary of Scientific Biography is a scholarly reference work, published from 1970 through 1980 by publisher Charles Scribner's Sons, with main editor the science historian Charles Gillispie, from Princeton University. It is supplemented by the New Dictionary of Scientific Biography. Both these publications are comprised in an electronic book, called the Complete Dictionary of Scientific Biography; the Dictionary of Scientific Biography is a scholarly English-language reference work consisting of biographies of scientists from antiquity to modern times, but excluding scientists who were alive when the Dictionary was first published. It includes scientists who worked in the areas of mathematics, chemistry and earth sciences; the work is notable for being one of the most substantial reference works in the field of history of science, containing extensive biographies on hundreds of figures. It gives information about both the personal biography and in considerable detail about the scientific contributions.

Engineers, social scientists and philosophers only appeared "when their work was intrinsically related to the sciences of nature or to mathematics." Though the Dictionary has worldwide coverage, the editors write that it focuses most on Western scientists, due to the limited availability of scholarship about Asian and Islamic historical scientists at the time. The articles in the Dictionary are 1–5 pages and are written by eminent historians of science. All articles list a selection of the original works of the subject, as well as a comprehensive list of the secondary literature about them, including early works as well as more contemporary ones; the first volume of the Dictionary was first put out in 1970, under the general editorship of Charles Coulston Gillispie. The set was completed in 1980; the Dictionary was published under the auspices of the American Council of Learned Societies by Charles Scribner's Sons in 16 volumes. Volume 15 is Supplement I. Volume 16 is the general index. A 2-volume Supplement II with additional biographies was published in 1990.

In 1981, after the 16-volume set was complete, Scribner's published a one-volume abridgment, the Concise Dictionary of Scientific Biography. Its second edition was published in 2001 and includes content from the 1990 Supplement II. In 1981, the American Library Association awarded the Dartmouth Medal to the Dictionary as a reference work of outstanding quality and significance; the New Dictionary of Scientific Biography, edited by Noretta Koertge, was published by Scribner's in December 2007 with 775 entries. Nearly 500 of these are new articles about scientists who died after 1950 and thus were not included in the original Dictionary; the other 250 are supplementary or replacement articles giving recent research and interpretation, intended to be read in conjunction with the corresponding articles in the original dictionary. The coverage now includes psychology, to a limited extent some areas of sociology and economics. In 2007, Charles Scribner's Sons published the Complete Dictionary of Scientific Biography as an e-book.

It includes the complete text of both print editions, with other finding aids. The e-book version is available as part of the Gale Virtual Reference Library. Many of the article are available online through HighBeam Research's encyclopedia portal; the DSB has been praised as a monumental undertaking. One reviewer of another work wrote that "The Dictionary of Scientific Biography has become the standard against which to measure all multi-volume biographical works in history of science."

Troitsky Bridge Building Competition

The Troitsky Bridge Building Competition is an annual event that takes place at Concordia University in Montreal, Canada in the spring. Participating teams of engineering students come from universities across Canada and the United States, they design and build model bridges out of popsicle sticks, white glue and dental floss. The competition began in the 1960s when Dr. Michael S. Troitsky, a professor in the Civil Engineering Department of Sir George Williams University spoke with students in his bridge design class about building bridge models similar to those in their course work. Students began building small-scale bridge models using wood and glue. By 1984, the department had become the Department of Building and Environmental Engineering of Concordia University and held the First Annual Bridge Building Competition; the contest was only open to Civil Engineering students enrolled at Concordia. The event expanded to include other universities in the province of Quebec those across Canada.

In 1991, the competition included its first international teams, from the United States. In 1988, the Civil Engineering graduating class created an award for most innovative concept, dedicated it to the memory of Lars Rowland, an alumnus who completed his B. Eng in 1988 at Concordia and was working as a civil engineer for Canadair when he died in 1990 piloting his plane; the inscription reads: "May his creativity and love of life serve to inspire you, as it has us, in the pursuit of your dreams."The Crusher, the hydraulic press which tests the strength of each bridge and is the focal point of the competition, has a history of its own. The original Crusher was a hydraulic device which, after ten years of service, was damaged beyond repair in 1994 - exploding hydraulic fluid all over the judges and competitors while attempting to crush the truss-bridge designed by Hugues Rivard, a Masters student at BCEE. A mark remains on the ceiling of the Hall Building Alumni Auditorium from the incident, the real capacity of Rivard's bridge remains a mystery.

The next Crusher was a donation from Wainbee in 1994. It was a screw jack style mechanism controlled by a computer, it could apply loads of up to 6000 pounds. In 2000, Mechtronix Inc. donated a new Crusher. During the 2000 competition, a bridge resisted up to 1860 kgf; the winner, however, is the one that has the highest overall score in terms of capacity, esthetic value, originality. For the 2010 competition a brand new crusher donated by Concordia's department of Building and Environmental Engineering and is follows its origins and is again a hydraulic jack; the 2006 competition was held on March 10. Over 40 teams participated in the event. Pictures of the event can be seen here. A short video of the competition can be seen on Discovery Channels page here The 2007 Competition took place on March 2, 2007. Picture gallery; the 2010 Competition took place on March 5, 2010.

Ye Ju

Ye Ju romanized as Yeh Chü, was a Chinese Nationalist general and governor of Guangdong Province. Ye was born in 1881, he first served under Long Jiguang. After Long's fall, he served with Chen Jiongming. After the fall of Yuan Shikai, amid China's Warlord Era, Sun Yat-sen's Nationalist rival government in Guangzhou vied for legitimacy with the Zhili Clique's Beiyang government in Beijing. With Ye's assistance, Chen Jiongming had restored Sun's government through the Yuegui Wars with the Old Guangxi Clique but by 1922 they were of two minds about whether to remain a regional power or to press towards a reunification of China through a northern expedition. Under Chen's regime, Ye oversaw Guangzhou. Sun was unable to dismiss Chen but threatened General Ye, saying he had "8-inch guns with poisonous shells capable of finishing off sixty battalions in three hours", ordered him to withdraw his men from Guangzhou within ten days. In response, Ye assaulted the Presidential Palace on 15 or 16 June 1922.

Sun had fled but his wife narrowly escaped shelling and rifle fire before meeting him on the gunboat Yongfeng where they were soon joined by Chiang Kai-shek. They hid it among the Whampoa anchorage's foreign ships, which Chen could not risk striking, held out for about 50 days, shelling Chen's positions and attempting to restore Sun to power. Conceding his lack of support, they reached Hong Kong on a British ship and took a steamer to Shanghai. Sun summoned the aid of members of the New Guangxi Clique, who drove Chen and Ye into eastern Guangdong. Ye died of an illness in late January, 1925.

Victor Ubogu

Victor Eriakpo Ubogu is a former Bath and England rugby union player. He came to the UK from Lagos, Nigeria in 1977 and attended West Buckland School in Devon where he received the school's top award, the Fortescue Medal. While at school he played for England Under 18s, he went on to the University of Birmingham to study Chemical engineering. While at university he played for Moseley, he went on to St Anne's College, Oxford where he was selected to play for the University of Oxford RFC and achieved his Blue. After leaving Oxford he joined Bath Rugby, he started for Bath in the victorious 1998 Heineken Cup Final. In 1992 he became a prop for the England national rugby union team where he remained until 1999. Combining the size and strength typical of a prop with unusual speed for a player specializing in this position, Ubogu was a effective ball-carrier in broken play. Against well-drilled international defences he sometimes lacked penetration, but he embarrassed club-level opposition. Ubogo founded the "Shoeless Joe's" chain of sports bars.

In 2001, Ubogu appeared on Lily Savage's Blankety Blank. Since 2004 he has run a successful, high-end travel and sporting hospitality company, using his initials as its name, VU Ltd.
