Photograph: Donaldson Collection/Getty Images Katherine Johnson obituary African-American mathematician who played a key role in landing men on the moon It was not the most arresting of titles: in 1959 the African-American mathematician Katherine Johnson, who has died aged 101, completed a paper entitled Determination of Azimuth Angle at Burnout for Placing a Satellite Over a Selected Earth Position. Thus did she become the first woman to have a credit on a report published by the flight research division of the newly created National Aeronautics and Space Administration (Nasa). Even more significantly, those calculations were at the basis of a crucial part of Johnson’s work for the astronaut John Glenn, when, in 1962, he became the first American to orbit the Earth. “Get the girl,” the astronaut had said, refusing to fly unless Johnson, with her maste

Katherine Johnson: Hidden Figures Nasa mathematician dies at 101 Pioneering African-American Nasa mathematician Katherine Johnson has died at the age of 101. Nasa announced her death on Twitter, saying it was celebrating her life and honouring "her legacy of excellence that broke down racial and social barriers". Ms Johnson calculated rocket trajectories and Earth orbits for Nasa's early space missions. She was portrayed in the 2016 Oscar-nominated film Hidden Figures. The film tells the story of African-American women whose maths skills helped put US astronaut John Glenn into orbit around the Earth in 1962. Ms Johnson verified the calculations made by new electronic computers before his flight.

An internal view of the novel "Al-Jinju .. The Earth Screws" by the novelist Abdel Aziz Baraka Sakin  Written by / Hatem Babiker Awad Al-Karim The Gingu are the product of wars and the destruction of rural societies. This collapse and destruction accompanies the loss of man’s social environment and he is forced to migrate internally for life.

Building a novel "Shouq Al-Darwish" by the novelist Hamour Ziyada  Written by / Hatem Babiker Awad Al-Karim The controversy raised by this narrator due to the sensitivity of its handling of the topic of historical events related to a set of facts that compels us to look at it from within to identify the techniques of novel writing used by the novelist Hammour in addition to his greatness. The current of consciousness has advanced techniques in creative writing. In its creative construction, the technique of multiple, interlaced temporal description, historical social time, psychological time, and internal (superstitious) time appears. All these times are combined in the novel "Longing the Darwish", which shows more than a narrative vision of the beauty of aesthetics and amazement. The historical time is usually characterized by the structure of the traditional novel in which time comes as a logical sequence and the novelist used it with skill that liberated hist

The definition of the novel "Al-Jinju .. the screws of the earth" - by the novelist Abdel Aziz Baraka Sakin  Written by / Hatem Babiker Awad Al-Karim The novel "Al-Jinju .. The Nails of the Earth" was shown by the Al-Tayeb Salih Prize for the Creative Novelist, held by the Abdul Karim Mirghani Cultural Center. The competition for novelist novelism is held to commemorate the Sudanese international novelist, Al-Tayeb Saleh, who authored the wonderful "Season of Migration to the North". "Gongo ... Earth Screws" won the award in 2009.

There are those who believed that the novel dealt with sex and politics, and that its board was full of "anxious silence" in the prevailing cu

Behavior building Umama Hassan Abdullah Al-Turabi Human beings meet at any official or customary level, setting themselves laws, rules and provisions that regulate their behavior in their interactions with each other and with their environment. Laws differ between formal and written laws and legislations that have administrative systems within the systems of government that are based on their application and care for their enforcement, and customary rules and rules that people know and compose in their small or large societies and on which the whole society is established, established, nurtured and applied. There is hardly any law without punitive procedures that criminalize some behaviors and punish them with what was agreed upon so that the specific and defective behavior does not spread in the particular community based on the idea that the punishment in whatever form is a deterrent to the person against it and to others so that they do not think about doing the same.
