[6] [page needed] Other Chinese inventions included the horse collar, cast iron, an improved plow and the seed drill. Mining and metal refining technologies played a key role in technological progress. Much of our understanding of fundamental chemistry evolved from ore smelting and refining, with De re metallica being the leading chemistry text ...
The Lower Paleolithic period lasted over 3 million years, during which there many human-like species evolved including toward the end of this period, Homo sapiens.The original divergence between humans and chimpanzees occurred 13 (), however interbreeding continued until as recently as 4 Ma, with the first species clearly belonging to the human (and not chimpanzee) lineage being ...
Benjamin Franklin pioneered the study of electricity by being the first to describe positive and negative charges, [61] as well as advancing the principle of conservation of charge. [62] Franklin is best known for the apocryphal feat of flying a kite in thunderstorm to prove that lightning is a form of electricity which, in turn, led to the ...
The history of technology is the history of the invention of tools and techniques by humans. Technology includes methods ranging from simple stone tools to the complex genetic engineering and information technology that has emerged since the 1980s.
Networks of such miniature tissues could become functional using stimulus-response training or organoid-computer interfaces – to potentially become "more powerful than silicon-based computing" for a range of tasks – and could also be used for research of various pathophysiologies, brain development, human learning, memory and intelligence ...
The tow truck was invented in 1916 by Ernest Holmes Sr., of Chattanooga, Tennessee. He was a garage worker who was inspired to create the invention after he was forced to pull a car out of a creek using blocks, ropes, and six men. An improved design led him to manufacture wreckers.

Painting of the Royal Institution by Thomas Hosmer Shepherd circa 1838. Founded in 1799 with the stated purpose of "diffusing the Knowledge, and facilitating the general Introduction, of Useful Mechanical Inventions and Improvements; and for teaching, by Courses of Philosophical Lectures and Experiments, the application of Science to the common Purposes of Life," the Royal Institution was a ...
Many of these inventions occurred late in the Hellenistic period, often inspired by the need to improve weapons and tactics in war. Hellenistic engineers of the Eastern Mediterranean were responsible for a number of inventions and improvements to existing technology. Archimedes invented several machines. Hellenistic engineers often combined ...
