Perhaps the most famous equation ever produced by the renowned theoretical physicist Albert Einstein was his theory of special relativity, written as E=mc2. This sequence of letters and numbers is, for the most part, common knowledge. But how many people actually know what E=mc2 means, or how it has shaped our understanding of the universe? What has he done for the ever-expanding field of science? More importantly, how did his discoveries affect world history?
Before the 1600’s, electricity was not a huge concept. The idea of electricity or the need for it was very foreign to several people. Until one day, in the 1700’s, when a man of the name Benjamin Franklin introduced this idea and made it into a reality with his invention of the Electrostatic Machine. The Electrostatic Machine laid the groundwork for understanding electricity and magnetism in depth. In the 1600’s, philosophers, scientists, and instrument makers created many devices to generate electrostatic charges, but was never to the full extent and paused with only their charges.
An English physicist named William Gilbert wrote books on the attractive nature of amber and used the Latin word "electricus" as a description. Several years later, another Englishman was inspired by Gilbert, his name was Thomas Browne. He wrote books on Physics, and created the word electricity to describe his investigations based Gilbert 's work. While being one of the many men who help to create electricity as we know it, Benjamin Franklin did not discover
Galvanometer has a word called sensitivity of galvanometer is defined as the current in micro ampere required to consume one millimeter deflection on a scale placed 1m away from a mirror. As with other formulas galvanometer has its own formula called a=the angle of deflection of the coil. Although, the currency of moving coil meters is dependent upon having a uniform and magnetic field. Is a very sensitive instrument used to measure the small currents of the order. Galvanometer gives the deflection which is proportional to the electric current flowing through it.
In his book, he used history as a medium to show that “that scientific progress depended more on the accumulation of “new facts” that anyone could discover than on the theoretical insights of a few men of genius”- John G. McEvoy. In his work with electricity, Joseph Priestley anticipated the inverse square law of electrical attraction, discovered that charcoal conducts electricity, and noted the relationship between electricity and chemical change between the two. Through the basis of these experiments, he was elected a member of the Royal Society of London in
Ever since Einstein first penned his famous equation, E = mc2, showing the world that there is energy stored in matter waiting to be harvested, mankind has been searching for new ways to free it. Initial work towards this goal led to the development of nuclear fission, the pinnacle of which was the successful Trinity Test in 1945. As time went on the technology was improved upon, resulting in nuclear power plants and more powerful weapons. Still, there was a desire for a more efficient, less dangerous, and more powerful means of extracting energy from matter. This desire was met with nuclear fusion.
J. Robert Oppenheimer Imagine how famous you would be if you were intelligent enough to help hundreds of scientists and physicists assemble nuclear weapons? Physicist J. Robert Oppenheimer must have felt the same way During World War II. Julius Robert Oppenheimer was born on April 22, 1904, in New York City. He was known as "The Father of the Atomic Bomb" because of his assistance with assembling nuclear weapons during World War II. He is also known for the Born-Oppenheimer Approximation; the assumption that the electronic motion and the nuclear motion in molecules can be separated.
According to the textbook, Germany had a team of scientists, which developed the idea of the atomic bomb. The United States decided to research on the atomic bomb because the country was very interested in this creation. However, Roosevelt was in fear of the consequences that could come about and therefore authorized an American atomic initiative. The result of this top-secret effort became known as the Manhattan Project and this eventually changed the course of human history. Additionally, the atomic bomb was tested and later labeled successful after the Manhattan Project began in 1942.
Tulia Peres “Solar Panels” Informative Speech Outline Introduction A. Attention Getter: Does anyone know what electric energy source works during the day and night? B. Background and Audience Relevance: As stated by C. Naff in his 2007 book Feeling the Future Solar power the development of the Solar Panels began during the mid-1800, this was during the Industrial Revolution to be able to heat up water and also steam for the machinery. In the year of 1839 French Scientist Alexandre Edmund Becquerel discovered the Photovoltaic process.
UNRAVELING NIKOLA TESLAS GREATEST SECRET: RADIANT ENERGY If all the great inventions and discoveries of Nikola Tesla, nothing stood out with greater potential benefit to the whole of humanity than his discovery of Radiant Energy in 1889. The series of observations that led to the discovery of Radiant energy initially grew out of experiments that Tesla had conducted in an attempt to duplicate the results that Heinrich Hertz had claimed to achieve in affirming the existence of electromagnetic waves, the discovery of which Hertz announced in 1887. While replicating Hertz’s experiments, Tesla experimented with violently abrupt DC electrical discharges and discovered a new force in the process. Only after conducting exhaustive experimental trials
