Marion Scheepers
Marion Scheepers is a South African-born mathematician, lecturer and researcher in the Department of Mathematics of Boise State University in Boise, Idaho since 1988. He is particularly known for his work on selection principles and on infinite topological and set-theoretical games. He introduced themes that are common to many selection principles and is responsible for the Scheepers diagram. Life Scheepers was born in December 1957, in Thabazimbi, South Africa.

Thabazimbi
Thabazimbi is an iron mining town in the Limpopo province of South Africa. The town is at the feet of the Ysterberg and is surrounded by the Witfonteinrand and Boshofberg with the majestic Kransberg in the background. The name Thabazimbi means ''mountain of iron'' because of the large iron ore reef that was discovered in 1919 by J. H. Williams. The mine boasts one of the largest mining shafts in Africa. More than 2 million tons of ore are mined every year and hauled by train to Mittal's iron and steel works. The railway line from Rustenburg reached the area in the 1930s and full scale iron and steel production began. The town was proclaimed in 1953. Kumba Iron Ore, previously Kumba Resources, is now the principal operator of the iron ore mine. The Marakele National Park Marakele National Park is a National Park, part of the Waterberg Biosphere in Limpopo Province, South Africa. Flora and fauna The park is accessible to all passenger vehicles, with the camp and tent sit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Single-cell Organism
A unicellular organism, also known as a single-celled organism, is an organism that consists of a single cell (biology), cell, unlike a multicellular organism that consists of multiple cells. Organisms fall into two general categories: prokaryotic organisms and eukaryotic organisms. All prokaryotes are unicellular and are classified into bacteria and archaea. Many eukaryotes are multicellular, but some are unicellular such as protozoa, unicellular algae, and unicellular fungi. Unicellular organisms are thought to be the oldest form of life, with early protocells possibly emerging 3.8–4.0 billion years ago. Although some prokaryotes live in Colony (biology), colonies, they are not specialised cells with differing functions. These organisms live together, and each cell must carry out all life processes to survive. In contrast, even the simplest multicellular organisms have cells that depend on each other to survive. Most multicellular organisms have a unicellular life-cycle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South African Mathematicians
South is one of the cardinal directions or compass points. The direction is the opposite of north and is perpendicular to both east and west. Etymology The word ''south'' comes from Old English ''sūþ'', from earlier Proto-Germanic ''*sunþaz'' ("south"), possibly related to the same Proto-Indo-European root that the word ''sun'' derived from. Some languages describe south in the same way, from the fact that it is the direction of the sun at noon (in the Northern Hemisphere), like Latin meridies 'noon, south' (from medius 'middle' + dies 'day', cf English meridional), while others describe south as the right-hand side of the rising sun, like Biblical Hebrew תֵּימָן teiman 'south' from יָמִין yamin 'right', Aramaic תַּימנַא taymna from יָמִין yamin 'right' and Syriac ܬܰܝܡܢܳܐ taymna from ܝܰܡܝܺܢܳܐ yamina (hence the name of Yemen, the land to the south/right of the Levant).

American Mathematical Society
The American Mathematical Society (AMS) is an association of professional mathematicians dedicated to the interests of mathematical research and scholarship, and serves the national and international community through its publications, meetings, advocacy and other programs. The society is one of the four parts of the Joint Policy Board for Mathematics and a member of the Conference Board of the Mathematical Sciences. History The AMS was founded in 1888 as the New York Mathematical Society, the brainchild of Thomas Fiske, who was impressed by the London Mathematical Society on a visit to England. John Howard Van Amringe was the first president and Fiske became secretary. The society soon decided to publish a journal, but ran into some resistance, due to concerns about competing with the American Journal of Mathematics. The result was the ''Bulletin of the American Mathematical Society'', with Fiske as editor-in-chief. The de facto journal, as intended, was influential in in ...

National Science Foundation
The National Science Foundation (NSF) is an independent agency of the United States government that supports fundamental research and education in all the non-medical fields of science and engineering. Its medical counterpart is the National Institutes of Health. With an annual budget of about $8.3 billion (fiscal year 2020), the NSF funds approximately 25% of all federally supported basic research conducted by the United States' colleges and universities.

University Of Witten-Herdecke
Witten/Herdecke University is a private, state-recognized, nonprofit university in Witten, North Rhine-Westphalia, Germany. It was the first German private institution of higher education to receive accreditation as a "Universität", a status recognizing the university's academic quality equivalent to state-run universities and granting the right to award bachelor's and master's degrees, doctorates, and the German Habilitation. Its foundation and history has often been marked by controversial debates and significant difficulties to establish the new university in the German educational system. In 1995, ''Times Higher Education'' noted that the university was considered by some "an idealistic model for the future of German higher education and yothers ... a carbuncle on the country's fiercely state-dominated university landscape". Today Witten/Herdecke University has succeeded in being recognized as one of Germany's few private universities considered ' Humboldtian' and as a ro ...

Encryption
In cryptography, encryption is the process of encoding information. This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext. Ideally, only authorized parties can decipher a ciphertext back to plaintext and access the original information. Encryption does not itself prevent interference but denies the intelligible content to a would-be interceptor. For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. It is possible to decrypt the message without possessing the key but, for a well-designed encryption scheme, considerable computational resources and skills are required. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients but not to unauthorized users. Historically, various forms of encryption have been used to aid in cryptography. Early encryption techniques were often used in military ...
