The Watt steam engine, a major driver in the industrial revolution, underscores the importance of engineering in modern history. This model is on display at the main building of the ETSII in Madrid, Spain. The concept of engineering has existed since ancient times as humans devised fundamental inventions such as the pulley, lever, and wheel.
Romans developed an intensive and sophisticated agriculture, expanded upon existing iron working technology, created laws providing for individual ownership, advanced stonemasonry technology, advanced road-building (exceeded only in the 19th century), military engineering, civil engineering, spinning and weaving and several different machines ...
He identifies four stages of human development, based on advances in the history of communication. In the first stage, information is passed by genes. In the second, when humans gain sentience, they can learn and pass information through experience. In the third, the humans start using signs and develop logic. In the fourth, they can create ...
The Hellenistic engineer and inventor Ctesibius (fl. 285–222 BC) fitted his clepsydras with a dial and pointer for indicating the time, and added elaborate "alarm systems, which could be made to drop pebbles on a gong, or blow trumpets (by forcing bell-jars down into water and taking the compressed air through a beating reed) at pre-set times ...
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 ...
If an earlier civilization existed on Earth millions of years ago, we might have trouble finding evidence of it -- but that doesn't mean it didn't exist.
Because of the increased complexity of engineering projects, many disciplines of engineer collaborate and specialize in sub fields. [41] One of these collaborations is the field of robotics, in which electrical engineers, computer engineers, and mechanical engineers can specialize in and work together.
The Neanderthal DNA found in modern human genomes has long raised questions about ancient interbreeding. New studies offer a timeline of when that occurred and when ancient humans left Africa.
