Abraham Lincoln, the sixteenth president of the United States, and Rutherford B. Hayes, the nineteenth president of the United States, were both Republicans who pursued a career in law prior to their presidency. Lincoln was an American politician who severed the United States until his assassination by John Wilkes Booth in 1865. In 1846, Lincoln ran for the United States House of Representatives and during his term he became known as an advocate for civil rights amongst those of color. Rutherford B. Hayes was an Ohio governor, Congressman, and a general aside from his presidency. Unlike Lincoln, Hayes suffered a heart attack and died in 1893.…
Middle Passage is divided into nine entries made by Rutherford Calhoun in a ship’s log. A newly freed slave, twenty-two-year-old Rutherford Calhoun arrives to New Orleans awaiting the new experience. His mischievous nature causes him to become deep in debt with a creole gangster, Papa Zeringue. He meets soon Isadora, although their personalities collide he is drawn to her unconventional attractiveness. Isadora soon becomes determined to marry Rutherford, she figures a woman like her would calm him down.…
Within these lectures he discussed his research on gases and liquids. This research gave remarkable new insight into the nature of gases. Thus became know as the Atomic Theory. The Atomic Theory states that: “all matter is made up of atoms which are indivisible and indestructible, all atoms of a given element are identical in mass and properties, compounds are formed by a combination of two or more different kinds of atoms, and a chemical reaction is a rearrangement of atoms” (Atomic Theory). Though most of this theory has held true we now know that atoms of the same element can have different masses and that atoms can be destroyed or subdivided in nuclear reactions.…
The first atomic model was introduced by an English chemist, physicist, and meteorologist named John Dalton. John Dalton had reintroduced the idea of the atom that had once been a theory of a Greek scientist named Democritus. However, unlike Democritus, Dalton was able to prove the existence of atoms. Through many experiments, Dalton came up with a list of properties, that he thought, all atoms shared.…
Scientists believe that stars are made of mostly gas, and this gas is made up of many atoms. In the star, the atoms in the gas bang into each other and give off different light depending on the type of atoms. This light from stars enables scientists to figure out the type and amount of atoms they are made of. Knowing the composition of the stars, we can guess how they were formed. Therefore we can see that stars are just atoms (hydrogen) hitting each other producing light.…
Teaching Observation of Professor Sandra Rutherford: I attended the first hour of a three hour class of Professor Sandra Rutherford from 6:00-7:00 of GEOS 103, Oceans and Atmosphere class. This class began with a student presentation about the garbage patch that is floating in the Pacific Ocean. The two students dressed up with garbage bags to illustrate the types of materials that end up in the garbage patch. Some of the highlights of the talk included the size of the patch about twice the size of Texas and the depth and damage done to the ocean floor and coral reefs. The assignment had a clear outline and inspiring students to dress up for a talk speaks well to inspiration that Professor Rutherford providers.…
Rutherford was the visionary who originally created the experiment and Geiger and Marsden were his assistants. Even though Rutherford didn't finish the experiment i think it's completely fair that the credit went to him. After the experiment Rutherford said: "It was quite the most incredible event that has ever happened to me in my life". That just goes to show how important this experiment was to him. In a way Rutherford was the one playing the Orchestra and his assistants were the musicians in it.…
Even though it caused mass destruction and death, the atomic bomb was a major breakthrough which ended World War II in controversial fashion. Although Richard Feynman played a major role in the Manhattan Project, he accomplished many other achievements and thoroughly explored the vast area of physics. Richard Feynman's childhood influenced his entire life. Before Richard was even born his father, Melville Feynman, said, "If it's a boy, he's going to be a scientist. " He claims In one of his books he wrote, What Do You Care What Other people Think, that his father taught him how to think, and his mother taught him humor.…
The Atomic Bomb is considered one of the most notorious and calamitous weapons in United States history. The atomic bombs, code named “Fat Man” and “Little Boy,” were considered breakthrough warfare technology when they were introduced to the world during the 1940s. Consequently, this powerful creation also came with catastrophic results. The effects were dangerous and harmful to living things, and they are still felt to this day. This infamous event started with the Manhattan Project in New York, which was led by physicist Julius Robert Oppenheimer and General Leslie Groves.…
rnest Rutherford was born on August 30, 1871, in Spring Grove, on the South Island of New Zealand. Rutherford resided in a family of 12 children, whose mother was a teacher and strongly believed in a good education for her children. Without this education, Rutherford would not have affected the atomic structure as much as he did. Rutherford, specializing in Physics, in 1895 was the very first research student at University of Cambridge’s Cavendish Laboratory in London. While at the Cavendish Lab, Rutherford worked with fellow scientist J.J. Thompson and studied the effects of X-Rays on the conductivity of gases and dividing atoms into molecules and atoms.…
Mendeleev lived and worked before there was a consensus on the constitution of an atom. Were they solid and uniform throughout with only mass differentiating between elements, or were they particulate and composed of certain “sub-atoms”? Mendeleev staunchly adhered to the former theory and explained certain phenomenon characteristic of electrons and protons (valence properties, radioactivity) as a result of this ether (book). Proving its existence would require extensive research enabled by assistants, expensive equipment, and laboratory space. Realizing the necessity of considerable funds for such a comprehensive endeavor, Mendeleev “[perpetuated] the false impression that he was interested in high-pressure research with applications to ballistics” and roped in government ministries to fund his research project (51).…
In 1897 was the year he had it discovered. It all started with a series of experiments to understand the nature of electric discharge, and it was being investigated by many other scientists during that time. He used the deflection of the rays with electric plates and magnets for an evidence of “bodies much smaller than atoms”. He thought having a very large value for the charge-to-mass ratio and he then found the value of the charge itself.…
According to his experiments, his team shot a positively charged beam at a gold foil, if Thomson’s model was correct, the ball of positive charges won’t be able to repel the beam (Like charge repel each other). Some were deflected strongly, so Rutherford thought that all the positively charges are packed in the middle of an atom. Two years later, a Danish scientist Niel Bohr proposed that electrons orbit in certain orbits. It seemed pretty advanced at that time, but it was soon proven incorrect. In the late 1920s, the cloud model was created.…
He proposed a model for the hydrogen atom, which explained the spectrum of the hydrogen atom. Also, there are only a limited number of orbits in which the electron dwell in. His assumptions were that the electron in a hydrogen atom travels around the nucleus in a circular direction, the energy of the electron in an orbit is proportional to its distance from the nucleus, and light is absorbed when an electron jumps to a higher energy level and emitted when an electron falls into a…
Rutherford did an experiment where he hit a thin piece of gold foil with alpha particles and was able to see the alpha particles pass through the gold foil. Alpha particles are positively charged due to the losing their electrons. This made Rutherford realized two things. He realized that atoms are made mostly made of empty space and that the positively charged particles, called a proton, were all packed together in a place called the nucleus. Rutherford made a model that fits his new atomic theory.…
