Sub-Saharan African countries spent on average 0.3% of their GDP on S&T (Science and Technology) in 2007. This represents a combined increase from US$1.8bn in 2002 to US$2.8bn in 2007. North African countries spend a comparative 0.4% of GDP on research, an increase from US$2.6bn in 2002 to US$3.3bn in 2007.
In essence, the Fourth Industrial Revolution is the trend towards automation and data exchange in manufacturing technologies and processes which include cyber-physical systems (CPS), Internet of Things (IoT), [25] cloud computing, [26][27][28][29] cognitive computing, and artificial intelligence. [29][30] Machines improve human efficiency in ...
Steam engines promoted automation through the need to control engine speed and power.. The introduction of prime movers, or self-driven machines advanced grain mills, furnaces, boilers, and the steam engine created a new requirement for automatic control systems including temperature regulators (invented in 1624; see Cornelius Drebbel), pressure regulators (1681), float regulators (1700) and ...
t. e. The Industrial Revolution, sometimes divided into the First Industrial Revolution and Second Industrial Revolution, was a period of global transition of the human economy towards more widespread, efficient and stable manufacturing processes that succeeded the Agricultural Revolution. Beginning in Great Britain, the Industrial Revolution ...
A cotton picker at work. The first successful models were introduced in the mid-1940s and each could do the work of 50 hand pickers. Mechanised agriculture or agricultural mechanization is the use of machinery and equipment, ranging from simple and basic hand tools to more sophisticated, motorized equipment and machinery, to perform agricultural operations.

Iron metallurgy in Africa concerns the origin and development of ferrous metallurgy on the African continent.Whereas the development of iron metallurgy in North Africa and the Horn closely mirrors that of the Ancient Near East and Mediterranean region, the three-age system is ill-suited to Sub-Saharan Africa, where copper metallurgy generally does not precede iron working.

1959 – Trevor Wadley invented the Tellurometer, the first successful microwave distance measurement device. 1962 – SANAE I, the first South African Antarctic base is built. [ 22][ 23] 1963 – The Dolos was developed in East London. 1965, 18 March – SAFARI-1, the first nuclear reactor on the African continent, goes critical.
1920-1925. Wilhelm Lenz and Ernst Ising created and analyzed the Ising model (1925) [45] which can be viewed as the first artificial recurrent neural network (RNN) consisting of neuron-like threshold elements. [9] In 1972, Shun'ichi Amari made this architecture adaptive. [46][9] 1920s and 1930s.
