Jan C. A. Boeyens
Jan C. A. Boeyens (1934–2015) was a South African chemist and educator. Boeyens was educated at the University of Pretoria. He worked at the Council for Scientific and Industrial Research of South Africa and at Stanford University. He became a professor of chemistry at the University of the Witwatersrand and Extraordinary Professor at UNISA. He has written or co-written more than 600 scientific contributions. Some of his books are used as textbooks of theoretical chemistry all over the world. As an emeritus he wrote books challenging the current scientific consensus about the adequacy of quantum mechanics in which he presented a way to establish more accurate modern physics and chemistry without using higher mathematics by using elementary number theory. Biography Education and career in chemistry Jan Boeyens was born 2 October 1934 in Wesselsbron, Free State, South Africa. He attended the University of the Orange Free State and in 1955 he obtained a BSc (Chemistry, Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wesselsbron
Wesselsbron is a small maize farming town 75 kilometres south of Bothaville in Free State province of South Africa. Town 32 km east of Hoopstad and 48 km north-west of Welkom. It was laid out in 1920 and became a municipality in 1936. Named after Commandant Cornelis J Wessels who was in command of the Siege of Kimberley from 13 October 1899 to 12 February 1900. Bron is Afrikaans for ‘source’, ‘spring’. Wesselsbron has a vast district which stretches from the Vet River in the south to the Vaal River in the north. The main cultivation is corn, but also wheat, sunflower and peanuts are cultivated. The grain silos of Senwes are the biggest silo complex in the Southern Hemisphere and can cope with the enormous amount of 275,000 tons of grain. Escorted tours can be organized to visit the silos as well as a private milling complex next to Senwes. Because of the growing demand for liquidated fertilizer, Omnia opened a factory in Wesselsbron in 1997, one of the biggest f ...

Who's Who Of Southern Africa
''Who's Who of Southern Africa'' is the name of an annual print publication distributed in Southern Africa, containing biographical information about prominent professionals in the Southern African region. According to the website, Southern Africa consists of South Africa, Namibia, Botswana, Zimbabwe, Lesotho, Swaziland and Mozambique. The book has been a source of information regarding noteworthy people in Southern Africa for over 100 years. Similar publications exist around the world, including the more famous annual British publication, ''Who's Who'', published since 1849 and the ''Who's Who in American Art'', a listing of prominent American artists. The original print publication provided lists of names and some biographical details of notable individuals in Southern Africa. Like the British version, inclusion was decided by a members prominence in public life, and /or his or her professional achievements. An online listing of the print publication was launched in 2001.

Differential Equation
In mathematics, a differential equation is an equation that relates one or more unknown functions and their derivatives. In applications, the functions generally represent physical quantities, the derivatives represent their rates of change, and the differential equation defines a relationship between the two. Such relations are common; therefore, differential equations play a prominent role in many disciplines including engineering, physics, economics, and biology. Mainly the study of differential equations consists of the study of their solutions (the set of functions that satisfy each equation), and of the properties of their solutions. Only the simplest differential equations are solvable by explicit formulas; however, many properties of solutions of a given differential equation may be determined without computing them exactly. Often when a closed-form expression for the solutions is not available, solutions may be approximated numerically using computers. The theory of d ...

Periodic Table
The periodic table, also known as the periodic table of the (chemical) elements, is a rows and columns arrangement of the chemical elements. It is widely used in chemistry, physics, and other sciences, and is generally seen as an icon of chemistry. It is a graphic formulation of the periodic law, which states that the properties of the chemical elements exhibit an approximate periodic dependence on their atomic numbers. The table is divided into four roughly rectangular areas called blocks. The rows of the table are called periods, and the columns are called groups. Elements from the same group of the periodic table show similar chemical characteristics. Trends run through the periodic table, with nonmetallic character (keeping their own electrons) increasing from left to right across a period, and from down to up across a group, and metallic character (surrendering electrons to other atoms) increasing in the opposite direction. The underlying reason for these trends is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Theory Of Relativity
General relativity, also known as the general theory of relativity and Einstein's theory of gravity, is the differential geometry, geometric scientific theory, theory of gravitation published by Albert Einstein in 1915 and is the current description of gravitation in modern physics. General theory of relativity, relativity generalizes special relativity and refines Newton's law of universal gravitation, providing a unified description of gravity as a geometric property of space and time in physics, time or four-dimensional space, four-dimensional spacetime. In particular, the ' is directly related to the energy and momentum of whatever matter and radiation are present. The relation is specified by the Einstein field equations, a system of second order partial differential equations. Newton's law of universal gravitation, which describes classical gravity, can be seen as a prediction of general relativity for the almost flat spacetime geometry around stationary mass distribution ...

Numerologists
Numerology (also known as arithmancy) is the belief in an occult, divine or mystical relationship between a number and one or more coinciding events. It is also the study of the numerical value, via an alphanumeric system, of the letters in words and names. When numerology is applied to a person's name, it is a form of onomancy. It is often associated with the paranormal, alongside astrology and similar to divinatory arts. Despite the long history of numerological ideas, the word "numerology" is not recorded in English before c. 1907. The term numerologist can be used for those who place faith in numerical patterns and draw inferences from them, even if those people do not practice traditional numerology. For example, in his 1997 book ''Numerology: Or What Pythagoras Wrought'' (), mathematician Underwood Dudley uses the term to discuss practitioners of the Elliott wave principle of stock market analysis.

Havenga Prize
The Havenga Prize (''Havengaprys'' in Afrikaans) is a prize awarded annually by the ''Suid-Afrikaanse Akademie vir Wetenskap en Kuns'' (South African Academy for Science and Arts) to a candidate for original research in the Sciences since 1945. Candidates are judged on the quality of research publications and evidence of the promotion of Afrikaans. The Havenga prize can only be awarded to a person once, but can be awarded posthumously. The prize is named after Finance Minister Nicolaas Christiaan Havenga, who donated £50 annually to the academy for the prize from 1946. A bequest of R4 000 was received from Havenga's estate and R14 000 from the estate of his wife, Olive. Since 1979 the prize has been awarded in the form of a gold medal.
