History of Engineering part 2

Historical Development of Engineering

Early Islamic Contributions to Science and Engineering

  • Islamic Science and Engineering: Emerged around 800 AD, emphasizing the importance of science as a foundational basis for engineering.

    • Engineering viewed as inspired by science and observation.

  • Ibn Sina (Avicenna):

    • Authored the Treatise on Wisdom, which discusses various scientific principles, such as lenses, mirrors, and automata.

Notable Figures in Islamic Science

  • Al-Biruni (973 AD):

    • Criticized the overreliance on Aristotle's authority:

    • Statement: "The trouble with most people is their extravagance in respect of Aristotle’s opinions: they believe that there is no possibility of mistake in his views, though they know he was only theorizing to the best of his ability.”

The Mongol Empire (Late 13th Century)

  • The Mongol Empire encompassed a significant part of the Eurasian landmass, extending from the Danube to the Pacific, impacting trade routes and cultural exchanges.

Medieval Engineering Developments

  • Apollodorus of Damascus:

    • Designed an apparatus for pouring boiling liquid over ramparts, showcasing advanced engineering techniques of the time.

Transfer of Technology from Islamic World to Europe (1100-1400)

  • Roger II of Sicily: Recruited Arab engineers to enhance his court's engineering capabilities.

  • Roger Bacon: Advocated for learning Arabic, Greek, and Hebrew instead of Latin, promoting a broader understanding of various scientific disciplines.

  • Hohenstaufen Kings of Germany: Continued the tradition of employing Islamic engineers, enriching European technology.

  • Henry the Navigator (Portugal): Utilized Islamic astronomical knowledge to facilitate exploration.

Industrial Engineering Innovations

  • 16th Century Smithy:

    • Featured a system utilizing two pairs of bellows driven by a crankshaft and connecting rod attached to a waterwheel to maintain high furnace temperatures.

    • Depicted in Le diverse et artificiose machine, published in 1588.

Renaissance and Advancements in Science

  • Leonardo da Vinci (1452-1519):

    • Notable for inventions such as an assault chariot equipped with guns, illustrating the merging of art and engineering.

  • Scientific Progress:

    • Copernicus proposed the heliocentric model where the earth revolves around the sun.

    • Francis Bacon (1561-1626):

    • Founded the Royal Society and introduced the concept of empirical research, advocating for the experimental method.

    • Asserted the need for a new understanding of science, distancing from reliance solely on Aristotle.

    • Quoted in The Advancement of Learning: "For as water will not ascend higher than the level of the first springhead from which it descendeth, so knowledge derived from Aristotle and exempt from liberty of examination will not rise again higher than the knowledge of Aristotle.”

The Industrial Revolution (Late 18th - 19th Century)

  • Technological advancements:

    • Steam engine innovation accelerated various technologies, including power looms.

    • The transition caused factories to recruit a larger workforce, altering societal dynamics:

    • England’s Enclosure Act forced workers into industrial employment.

    • Factories often described as loud and unpleasant environments, leading to further societal critique from groups like the Luddites, who rejected technological machinery.

  • Cities in England, 1750 vs. 1850:

    • Significant growth in populations within urban centers, necessitating infrastructure and transportation advancements.

Engineering in the 20th Century

  • At the dawn of the 20th century, distinctions between science and engineering became more pronounced.

    • Notable developments during and after World War I showcased engineering’s application to practical challenges:

    • Science demonstrated its utility in warfare, particularly in artillery and communications.

  • Innovative Patents & Inventions:

    • Thomas Edison: Patented the incandescent lamp on January 27, 1880, showing developments in electrical engineering.

    • Wright Brothers (1904) & Henry Ford: Key figures in early aviation and automotive engineering, respectively.

World War Innovations and Technological Advances

  • Advancements in Warfare Technology:

    • Introduction of new weaponry such as poison gas (e.g., xylyl bromide, chlorine, phosgene, mustard gas) and tanks during WWI, challenging traditional combat strategies.

  • The Development of the Triode Valve:

    • Functionality included amplification, switching, and binary signal storage, laying groundwork for modern electronics.

Cybernetics and Control Systems

  • Norbert Wiener: Recognized as the father of cybernetics, examining control and communication in animals and machines.

The Evolution of Rocketry and Missile Technology**

  • Detail on V-2 rockets and potential applications influenced future aerospace endeavors, with the legacy extending into ICBM technologies.

Nuclear Advancements and Military Applications

  • Enrico Fermi: Built the first nuclear reactor at the University of Chicago in 1942, marking significant progress in nuclear engineering and energy.

Philosophy and Resistance to Change in Engineering

  • Critical Perspectives:

    • The shifting role of engineering professionals reflects broader societal trends, with quotes like Werner von Braun urging engineers in the US space program to identify more as scientists.

  • Definition of Engineering:

    • Described as “the systematic application of scientific knowledge to the betterment of the human condition,” highlighting its evolving nature through different eras.
