Thomson discovered electrons through his cathode ray experiment and proved that atoms were divisible(1897) (McPhee, 2010), ("A brief history," 2005) 20th century concepts and discoveries •Earnest Rutherford discovered that there was a small, dense positively charged nucleus, predicted the existence of neutrons, stated that electrons move rapidly in the empty space around the nucleus (1909-11) •In continuation of his experiments J.J. Thompson determined that all particles had charges that were multiples of the same number •In 1913 Robert Millikan accurately determined the mass of election…

    One of the most historical tools was the telescope. Which Galileo Galilei perfected the telescope that was originally created by Hans Lippershey. Most of the earliest versions of the telescope used a curved lens made of polished glass at the end of a tube to magnify objects to a factor of 3x. Galileo was the first person to actually see different masses far within space. It gave way for scientists to see stars, planets, and space. Also, the telescope helped scientists to venture out and study planet surfaces. (Wethington, 2009)…

    Industrial Revolution Research Paper

    Not only did the physical advancements bring change to the world, but the mental and scientific advancements also brought the same amount of change if not more. With dedicated philosophers and innovative minds, the world saw the evolution of anatomy, chemistry, electricity, and medicine. It was in 1796 that the cure for the lethal smallpox was invented, thanks to Edward Jenner (Murdarasi). Ever since the vaccine was invented, the world of today has yet to witness another smallpox case. During the Industrial Revolution, it was chemistry of the four scientific practices that received the most attention and progression. The periodic table of today is extensive and intricate, each element composed of different materials and compounds. By 1789, Antoine Lavoisier had discovered a total of twenty-three elements, as well as devised a method of etymology for chemical compounds. As the years passed, men of different backgrounds discovered the components that made up air: nitrogen (Daniel Rutherford, 1772), oxygen (Joseph Priestly, 1774), carbon dioxide (Joseph Black), and hydrogen (Henry Cavendish, 1776). There was also a theory devised by Cavendish that when oxygen and hydrogen were combined, the product was that of water…

    History of Science and Technology

    For centuries it was religion that had kept contemporaries of science in the shadow. Any sort of advance to explain a certain phenomena in ways other than that of God’s doing could eventually end up in one’s demise. However, what happens when religion loosens its grip on science or as some may argue loses its appeal to the masses due to an influx of intellectual material? This paper will outline the key stages during the period of 1400-1700 (the Renaissance) in which religion and science co-exist on a scale far larger than before. Prior to this period, the works of Aristotle were most commonly affiliated with religion. Although some of Aristotle’s ideas caused tension towards Christianity, scholars noticed some similarities with Aristotle’s matter theory and Christian doctrine. An example of this was the “Christian soul and it could be explained as the “form” of the body, the immaterial feature that gives the body its defining essence (Ashworth, Kit, p. 67)”. Religious contemporaries at the time felt no threat by Aristotle’s theory of form and matter and it continued to present itself until the 17th century. The relevance of this is simply that religion was the only way in which scientific endeavors were possible or even allowed, most scholars eventually credited God at some point in their work, which deemed it possible to continue or even publish.…
