Ethan Vishniac
Ethan Tecumseh Vishniac (born 1955) is an American astrophysicist. He is the Editor-in-Chief of the Astrophysical Journal and a professor of Astronomy at Johns Hopkins University in Baltimore, after holding positions at University of Saskatchewan in Saskatoon, McMaster University in Hamilton, Ontario, Canada, and University of Texas in Austin. Education Vishniac graduated from University of Rochester and Harvard University. He received his Ph.D. in astrophysics in 1980 from Harvard University while working under the direction of William H. Press. After Harvard, Vishniac spent two years as a post doctoral fellow working under Jeremiah P. Ostriker at Princeton University. Research His best known scientific work is the study of instabilities in expanding blast waves. In Vishniac (1983), he demonstrated that a blast wave expanding in a sufficiently compressible medium would be subject to a linear overstability growing as the square root of time. This is usually known as the Vishni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roman Vishniac
Roman Vishniac (; russian: link=no, Рома́н Соломо́нович Вишня́к; August 19, 1897 – January 22, 1990) was a Russian-American photographer, best known for capturing on film the culture of Jews in Central and Eastern Europe before the Holocaust. A major archive of his work was housed at the International Center of Photography until 2018, when Vishniac's daughter, Mara Vishniac Kohn, donated it to The Magnes Collection of Jewish Art and Life at the University of California, Berkeley. Vishniac was a versatile photographer, an accomplished biologist, an art collector and teacher of art history. He also made significant scientific contributions to photomicroscopy and time-lapse photography. Vishniac was very interested in history, especially that of his ancestors, and strongly attached to his Jewish roots; he was a Zionist later in life.ICP Library of Photographers. ''Roman Vishniac''.

Wolf V
The wolf (''Canis lupus''; : wolves), also known as the gray wolf or grey wolf, is a large canine native to Eurasia and North America. More than thirty subspecies of ''Canis lupus'' have been recognized, and gray wolves, as popularly understood, comprise wild subspecies. The wolf is the largest extant member of the family Canidae. It is also distinguished from other ''Canis'' species by its less pointed ears and muzzle, as well as a shorter torso and a longer tail. The wolf is nonetheless related closely enough to smaller ''Canis'' species, such as the coyote and the golden jackal, to produce fertile hybrids with them. The banded fur of a wolf is usually mottled white, brown, gray, and black, although subspecies in the arctic region may be nearly all white. Of all members of the genus ''Canis'', the wolf is most specialized for cooperative game hunting as demonstrated by its physical adaptations to tackling large prey, its more social nature, and its highly adva ...

Vishniac (crater)
Vishniac is the larger crater of the Martian surface feature called the Giant's Footprint. It was named after Wolf V. Vishniac, a microbiologist who died on an expedition to Antarctica. Professor Carl Sagan felt very bad for the scientist, and so found an unnamed crater at the exact longitute and latitude that he died on Mars and named it after him. The feature was originally observed by Mariner 7 in 1969. In 1999, the Mars Global Surveyor's Mars Orbiter Camera was able to provide more detailed pictures. The crater measures approximately in diameter. Its name was approved by the International Astronomical Union The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisation with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreac ... in 1976.
