Bronisław Knaster
Bronisław Knaster (22 May 1893 – 3 November 1980) was a Polish mathematician; from 1939 a university professor in Lwów and from 1945 in Wrocław. He is known for his work in point-set topology and in particular for his discoveries in 1922 of the hereditarily indecomposable continuum or pseudo-arc and of the Knaster continuum, or buckethandle continuum. Together with his teacher Hugo Steinhaus and his colleague Stefan Banach, he also developed the last diminisher procedure for fair cake cutting. Knaster received his Ph.D. degree from University of Warsaw in 1925, under the supervision of Stefan Mazurkiewicz.

Harvard College Observatory
The Harvard College Observatory (HCO) is an institution managing a complex of buildings and multiple instruments used for astronomical research by the Harvard University Department of Astronomy. It is located in Cambridge, Massachusetts, United States, and was founded in 1839. With the Smithsonian Astrophysical Observatory, it forms part of the Center for Astrophysics Harvard & Smithsonian. HCO houses a collection of approximately 500,000 astronomical plates taken between the mid-1880s and 1989 (with a gap from 1953–1968). This 100-year coverage is a unique resource for studying temporal variations in the universe. The Digital Access to a Sky Century @ Harvard project is digitally scanning and archiving these photographic plates. History In 1839, the Harvard Corporation voted to appoint William Cranch Bond, a prominent Boston clockmaker, as "Astronomical Observer to the University" (at no salary). This marked the founding of the Harvard College Observatory. HCO's first tele ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Katherine Sopka
Katherine Sopka (born Katherine J. Russell) was a science interviewer, physics professor and historian of physics. She is known for her interviews held with leading scientists, and for work on the history of quantum physics and the physics community in the U.S. in the 1920s and 1930s. Life Katherine was born fourth of six children in Dorchester, Boston, and attended Girl's Latin School in Boston. She studied at Radcliffe College, where she obtained her bachelor's degree in physics. She married John J. Sopka in 1943, and the couple subsequently moved to Dayton, Ohio, where her husband worked with the Manhattan project until the end of the war. They both intended to complete their graduate degrees and returned to Harvard, where Katherine earned her master's degree in physics and John his Ph.D. in mathematics.

Office Of Scientific Research And Development
The Office of Scientific Research and Development (OSRD) was an agency of the United States federal government created to coordinate scientific research for military purposes during World War II. Arrangements were made for its creation during May 1941, and it was created formally by Executive Order 8807 on June 28, 1941. It superseded the work of the National Defense Research Committee (NDRC), was given almost unlimited access to funding and resources, and was directed by Vannevar Bush, who reported only to President Franklin Delano Roosevelt. The research was widely varied, and included projects devoted to new and more accurate bombs, reliable detonators, work on the proximity fuze, guided missiles, radar and early-warning systems, lighter and more accurate hand weapons, more effective medical treatments (including work to make penicillin at scale, which was necessary for its use as a drug), more versatile vehicles, and, the most secret of all, the S-1 Section, which later be ...

Department Store
A department store is a retail establishment offering a wide range of consumer goods in different areas of the store, each area ("department") specializing in a product category. In modern major cities, the department store made a dramatic appearance in the middle of the 19th century, and permanently reshaped shopping habits, and the definition of service and luxury. Similar developments were under way in London (with Whiteleys), in Paris (Le Bon Marché) and in New York ( Stewart's). Today, departments often include the following: clothing, cosmetics, do it yourself, furniture, gardening, hardware, home appliances, houseware, paint, sporting goods, toiletries, and toys. Additionally, other lines of products such as food, books, jewellery, electronics, stationery, photographic equipment, baby products, and products for pets are sometimes included. Customers generally check out near the front of the store in discount department stores, while high-end traditional department sto ...

Prince School Of Business
A prince is a male ruler (ranked below a king, grand prince, and grand duke) or a male member of a monarch's or former monarch's family. ''Prince'' is also a title of nobility (often highest), often hereditary, in some European states. The female equivalent is a princess. The English word derives, via the French word ''prince'', from the Latin noun , from (first) and (head), meaning "the first, foremost, the chief, most distinguished, noble ruler, prince". Historical background The Latin word (older Latin *prīsmo-kaps, literally "the one who takes the first lace/position), became the usual title of the informal leader of the Roman senate some centuries before the transition to empire, the ''princeps senatus''. Emperor Augustus established the formal position of monarch on the basis of principate, not dominion. He also tasked his grandsons as summer rulers of the city when most of the government were on holiday in the country or attending religious rituals, and, for ...
