Leslie Leiserowitz
Leslie Leiserowitz ( he, לסלי ליזרוביץ, born 1934 in Johannesburg) is an Israeli chemist and crystallographer. Leiserowitz studied electrical engineering at the University of Cape Town with a bachelor's degree, and then worked briefly as an electrical engineer and received a master's degree in physics (X-ray crystallography, under Reginald William James). In 1959 he joined the X-ray crystallography department at the Weizmann Institute under Gerhard Schmidt, a student of Dorothy Crowfoot-Hodgkin. The group at the Weizmann Institute has an international reputation in solid-state chemistry. From 1966 to 1968 he set up the organic chemistry X-ray crystallography department at the University of Heidelberg at the invitation of Heinz Staab. There he developed and installed computer programs using the direct method of Nobel Laureates Herbert Hauptman and Jerome Karle. Back at the Weizmann Institute, Leiserowitz worked on the synthesis of molecules for the investigation of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johannesburg
Johannesburg ( , , ; Zulu and xh, eGoli ), colloquially known as Jozi, Joburg, or "The City of Gold", is the largest city in South Africa, classified as a megacity, and is one of the 100 largest urban areas in the world. According to Demographia, the Johannesburg–Pretoria urban area (combined because of strong transport links that make commuting feasible) is the 26th-largest in the world in terms of population, with 14,167,000 inhabitants. It is the provincial capital and largest city of Gauteng, which is the wealthiest province in South Africa. Johannesburg is the seat of the Constitutional Court, the highest court in South Africa. Most of the major South African companies and banks have their head offices in Johannesburg. The city is located in the mineral-rich Witwatersrand range of hills and is the centre of large-scale gold and diamond trade. The city was established in 1886 following the discovery of gold on what had been a farm. Due to the extremely large gold de ...

Scientists From Johannesburg
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

University Of Cape Town Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university i ...

The EMET Prize For Art, Science And Culture
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a v ...

Meir Lahav
Meir Lahav ( he, מאיר להב, born 1936 in Sofia, Bulgaria) is an Israeli chemist and materials scientist and emeritus professor at the Weizmann Institute of Science. Lahav emigrated to Israel in 1948. He studied at the Hebrew University of Jerusalem, where he obtained a master's degree in polymer chemistry in 1962. With Gerhard Schmidt at the Weizmann Institute of Science, he obtained a Ph.D. in solid state chemistry. As a postdoctoral fellow, Lahav worked with Paul Doughty Bartlett at Harvard University, among others, before returning to Israel in 1971. Since 1985 he has held a full professorship at the Weizmann Institute. In a long-term collaboration with Leslie Leiserowitz, Lahav dealt with how crystal formation and growth can be influenced by targeted impurities (useful impurities) and with the direct determination of the sense of chirality of molecules. He investigated crystallization and interface phenomena such as the packing of amphiphilic molecules at the phase bou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herbert Hauptman
Herbert Aaron Hauptman (February 14, 1917 – October 23, 2011) was an American mathematician and Nobel laureate. He pioneered and developed a mathematical method that has changed the whole field of chemistry and opened a new era in research in determination of molecular structures of crystallized materials. Today, Hauptman's direct methods, which he continued to improve and refine, are routinely used to solve complicated structures. It was the application of this mathematical method to a wide variety of chemical structures that led the Royal Swedish Academy of Sciences to name Hauptman and Jerome Karle recipients of the 1985 Nobel Prize in Chemistry. Life He was born in to a Jewish family in New York City, the oldest child of Leah (Rosenfeld) and Israel Hauptman. He was married to Edith Citrynell since November 10, 1940, with two daughters, Barbara (1947) and Carol (1950). He was interested in science and mathematics from an early age which he pursued at Townsend Harris High S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
