He then decided to end painting in order to begin finding a way to improve long distance communication. This invention would eventually highly influence the Industrial Revolution in America. (art) In 1832, he met Charles Thomas Jackson who knew about electromagnetism. Morse developed the concept of a telegraph with a single wire. The original telegraph by Morse was submitted with his application for a patent is now at the National Museum of American History at
Research Investigation Was the dropping of the atomic bomb justified? By Oscar Jungstedt 10 History Scotch College SOSE Research Investigation: By Oscar Jungstedt 1195 words (excluding quotes) “I made one great mistake in my life,' he said to Linus Pauling, who spent an hour with him on the morning of November 11, 1954, '...when I signed the letter to President Roosevelt recommending that atom bombs be made” Physicist Albert Einstein, one of the smartest men in history, who’s whole life was about taking risks said he had one major regret: sending a letter recommending the president about the atomic bomb. These two sentences practically sum up the dropping of the atomic bomb on Hiroshima to be completely unjustified. The bomb was
Einstein used a combination of theories on mass, energy and light to come up with his formula of e=mc2 and from that he became the father of modern physics. Michael Faraday was an uneducated English blacksmith who grew up in the 19th century. When Faraday was 20, he received tickets to a series of lectures at the Royal Institution that was the beginning of his journey into science . Faradays interests in science soon brought him to the top of his field where he discovered the invisible fields of electricity and magnetism .He created the law of conservation of energy which is the total amount of energy in an isolated system remains constant over time. Faraday also discovered the electromagnetic waves when conducting an experiment that later on led to the invention of the electric motor.
Charles L. Reason Algebra II Trig Charles L. Reason was born July 21, 1818 in New York City to West Indies immigrants Michael and Elizabeth Reason. Charles attended the African Free School along with his brothers Elmer and Patrick both who are important historical figures in their own right. An excellent student in mathematics, Reason became an instructor in 1832 at the school at age fourteen this became a striking matter for the news, receiving a salary of $25 a year. He used some of his earnings to hire tutors to improve his knowledge. Later, he decided to enter the ministry but was rejected because of his race by the General Theological Seminary of the Protestant Episcopal Church in New York City.
Figure 2 shows a circuit with a resistor R = 1.0 × 103 Ω, and a battery with potential diﬀerence of VB = 5.0V . (a) Solve the circuit in Figure 2. That is, ﬁnd all unknown currents, voltages, and resistances. (b) What is the direction of the current? Note: I want the direction of the conventional current.

Yours sincerely, The document became the first stepping-stone towards the 1948 establishment of the state of Israel. The declaration was driven by one of Britain’s leading Zionists, Dr. Chaim Weizmann. A leading chemist, Dr. Weizmann had developed a new means of making acetone, critical to the military explosive cordite, which was in turn critical to the British war effort. In response to his defense contribution, and to his unflagging lobbying efforts, the British cabinet agreed to consider the question of a Jewish homeland, and eventually put forth Lord Balfour’s letter. The document was, however,

In 1787, it is believed that Benjamin Franklin designed the first penny, called “Fugio”, when the Constitutional Congress authorized the minting of the first currency. The design included a detailed sun, shining down on the words, “Mind Your Business” at the bottom and on the back, “ We Are One”, with a chain of thirteen interlocking
Soon after the invention caught on, the tin foil was replaced by cylindrical cardboard coated in wax, and eventually vinyl which of course is still used today. The gramophone was invented in 1887 by a German immigrant named Emile Berliner, and while it was based on the same concept of Edisons phonograph, Berliners invention was the first to record sound and play it
