1831- Using his invention the induction ring, Michael Faraday proved that electricity can be induced (made) by changes in an electromagnetic field. Faraday’s experiments about how electric current works, led to the understanding of electrical transformers and motors. This experiment became Faraday’s Law, which became one of the Maxwell Equations (Administrator, 2007). 1890 - Heinrich Hertz (1857-1894) a German physicist, laid the ground work for the vacuum tube. He laid the foundation for the future development of radio, telephone, telegraph, and even television.
I.6.2 Flamethrowers The first modern flamethrower, Flammenwerfer, was invented by German engineer Richard Friedler in 1901. These powerful weapons used pressurized air, carbon dioxide or nitrogen to push oil through a nozzle, which was ignited by a charge, producing a jet of flame. Flame throwers were mainly used to clear enemy soldiers from the trenches. Richard Friedler developed two types of flamethrowers – the smaller version Kleinflammenwerfer was a portable one carried by one person, and the larger version Grossflammenwerfer was suitable for transportation, also by a single person. From 1911 onwards, the German army deployed flamethrowers in three specialized battalions.
In 1932 James Chadwick discovered a second particle in the nucleus, he fired alpha particles at beryllium and found that neutrons were released. He revised Bohr’s model of the atom to include a representation of both protons and neutrons in the visual diagram. Today we know that electrons orbit a nucleus made up of protons and neutrons and that the electrons can be described as both waves and
In addition to electricity, Tesla experimented with radio waves and much of Guglielmo Marconi’s, inventor of the radio, work was based off of Tesla’s research. Throughout his life, Tesla was granted 111 U.S. patents and every electrical appliance today uses at least one of Tesla’s inventions. In addition to how Tesla affected the world, Einstein left his mark on America’s technology and inventions. One major invention Einstein contributed to was the atomic bomb. The invention of the atomic bomb was a turning point in World War 2 when they dropped the bombs on the cities of Hiroshima and Nagasaki.
984 - Ibn Sahl and refraction Persian scientist Ibn Sahl writes on burning mirrors and lenses, which sets out his understanding of how curved mirrors and lenses bend and focus light. He discovers a law of refraction mathematically equivalent to Snell’s law (1615). 1021 - Intromissionist
Hot Air Balloon Analysis In the duration of this project there were many factors that needed to be kept into consideration. The most important was the laws of gas, because the hot air balloon needed to be be constructed enough to withstand the air and have enough room for the hot air particles to move making the balloon have a successful flight. Due to the hot air particles move as a faster rate making then collide to each other which causes the balloon to have enough energy to take flight. While actually launching the ballon I began to see the balloon that did take flight and those who did not. In the beginning of the class launch many of the hot air balloon were successful.
While we listen to music, the brain is stimulated in the frontal lobe, amygdala, and hippocampus, which are the main areas that control our emotions. The hippocampus is connected to emotional responses which impacts the release of brain chemicals. Stefan Koelsch explains the impact the hippocampus has to do with music, “The fact that the hippocampus reacts to emotional music (including fear and joy) suggests that it is responsive to the potential of music to stimulate the release of brain chemicals that affect its function, by virtue of that music’s emotional associations and core meaning” ( Williamson). Music has a big impact on brain stimulation. As our brain is stimulated it produces chemicals that can also impact our mood, “Listening to music increases the neurotransmitter dopamine.
He is mostly known for his mass–energy equivalence formula E = mc2, which has been recognized as "the world 's most famous equation". ii. Can you give me an example of one of his contributions do science? 1. In the year of 1905, Albert Einstein published a paper advancing the hypothesis that light energy is carried in discrete quantized packets to explain experimental data from the photoelectric effect.
This helped prove his theory of the proton’s existence because when the alpha radiation occurred it turned the old element into a new element by removing two protons. Lastly the article also mentions that, “In 1898, Ernest Rutherford began studying the radiation emitted by uranium. His experiments led him to conclude that radioactivity must have at least two components; and he named them alpha and beta rays after the first two letters of the Greek alphabet.” The research he conducted lead him to realized that beta rays were way more penetrating than alpha
He predicted the discovery of more elements, and left spaces open in his periodic table for them. In 1894, Sir William Ramsay and Lord Rayleigh discovered the noble gases. The noble gases group was then incorporated into the periodic table. In 1897 physicist J. J. Thomson first discovered electrons; small negatively charged particles in an atom. John Townsend and Robert Millikan later on were able to determine their exact charge and mass.
