Atomic Bomb Essays

“Little BOY’ dropped over the Japanese town of Hiroshima was so devastating that the people only had an instant to react before feeling the effects? “A Noiseless Flash”, the first chapter in the novel Hiroshima was written by John Hershey, 1914-1993, describes the overall situation and feelings of the bomb through six characters. John Hershey […]

done in the United States, by a group of the best scientists; this research was given the name of “The Manhattan Project”. On Monday July 16th, 1945, a countdown for the detonation of the first atomic bomb took place near Los Alamos, New Mexico. This atomic bomb testing would forever change the meaning of war. […]

J. Robert Oppenheimer was a brilliant physicist and known as the Father of the Atomic Bomb. A charismatic leader of rare good qualities and commonplace flaws, Oppenheimer brought an uncommon sensibility to research, teaching, and government science. After help creating the atomic bomb with the Manhattan Project he was banned from the U.S. Government during […]

Michael Levin is a philosophy professor at City University of New York. As a scholar, his works are mostly related to philosophy and one of his masterpiece is the article The Case for Torture, which was published by Newsweek in 1982. In this article, he argued that using torture as a means to save many […]

The Clan of One-Breasted Woman by Terry Tempest Williams is a story that describes the tale of the family of a young girl that has struggled with cancer. Terry says that her mother, grandmother and her six of her relatives had mastectomies. Only two survived, she and her aunt and they had to go through […]

An electron microscope is a type of microscope that produces an electronically-magnified image of a specimen for detailed observation. The electron microscope (EM) uses a particle beam of electrons to illuminate the specimen and create a magnified image of it. The microscope has a greater resolving power than a light-powered optical microscope, because it uses […]

In any case, only one atomic mass can be an integer because of the difference in mass between a proton and neutron, and the fact that the sum of the particle masses for any isotope is not equal to the mass of the isotope. There are different isotopes of the elements. The atomic weight is […]

In this paper I will discuss the element called Radon.  I will explain how and when this element was discovered, its’ physical characteristics, the natural environment of the element and the abundance in which it occurs. In addition, I will describe why Radon is important to humans, and other interesting facts related to this element.Radon […]

Objective: To determine experimentally the water of hydration for the hydrate Borax. Theory: In this experiment, we examined and found the water of hydration of the hydrate borax. Borax is derived from the element Boron, which is a metalloid chemical element with properties between those of carbon and aluminum(95CI). Boron is relatively rare, constituting only […]

Have you ever done the laundry and wondered what was in the detergent you use? Or if you watched a rocket launch into space have you wondered how it can even make it past earth? The answer to those questions is boron (B). Boron is a metalloid element with an atomic number of 5 and […]

Fossil fuels provide both energy and raw materials such as ethylene, for the production of other substances construct word and balanced formulae equations of chemical reactions as they are encountered. There are three important steps involved:  Show all reactants and all products in the word equation. Write the correct formula for each reactant and each […]

Technetium is a chemical element with the symbol Tc and atomic number 43. It consists of 43 protons and has a mass number determined by its 55 neutrons, giving it a total of 98. Technetium is classified as a transition metal and belongs to the d-block in the periodic table. It can be found in […]

Abstract: One is to determine the gap energy of cadmium sulfide semiconductor thin film using the equation: Eg = h.c/ is the signal of the long wavelength limit of the absorption peaks (measured in the lab). The reaction between cadmium sulfide and NH3, in the presents of thiourea yield a ? of 579(nm). The  error […]

Introduction The purpose of the flame lab was to identify a set of flame-test color standards for selected metal ions, relate the colors of a flame test to the behavior of excited electrons in a metal ion, observe spectral lines using diffraction grating, and to identify an unknown metal ion by using a flame test. […]

A quantum dot is a nanoparticle or nanocrystal, a billionth of a meter in size [1]. These dots belong to the class of materials called semiconductors, which are actually crystals made of “periodic groups of II-VI, III-V, or IV-VI materials [2]. ” Semiconductors are, of course, the foundation of the modern-day electronics industry. Whether they […]

Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule. It determines several properties of a substance including its reactivity, polarity, phase of matter, color, magnetism, and biological The angles between bonds that an atom forms depend only weakly on the rest of the molecule, I. E. They can be understood as […]

Chemical Basis of Color in Fireworks? Abstract The purpose of the first experiment was to see the light spectra of different elements, and confirm that each element shows unique emission spectra, in terms of being able to identify an unknown substance. The analysis is expected to show that elements do indeed have unique emission spectra, […]

This page explains what electronegative Is, and how and why it varies around the Periodic Table. It looks at the way that electronegative differences affect bond type and explains what is meant by polar bonds and polar molecules. If you are interested in electronegative in an organic chemistry context, you will find a link at […]

Photocopying is a quick and cheap process of reproducing documents or materials. Mostly, photocopying process is with the use of dry heating called Xerography. Photocopying Machine The photocopy machine a worldwide used electronic machine which are useful both in school and offices. It can be used by a person to reproduce even much volume of […]

Blackbody radiation is the electro-magnetic radiation emerging from a small hole in a perfectly black box containing electromagnetic radiation at a high temperature. Scientists were interested in setting standards for the electric and thus measured the distribution of the total electromagnetic energy in a black box among the different wavelengths of the light. But not […]

James Hillier, one of the entrepreneurs of the electron microscope, was born on August 22nd, 1915 in Brantford, Ontario. He attended the University of Toronto, where he received a PhD in 1941. After graduating, Hillier spent most of his career at the Radio Corporation of America (or RCA), discovering the principle of stigmator, which is […]

Some atoms contain loosely attached electrons. These electrons can be made to move easily from one atom to another. When these electrons move freely along a path, a current of electricity is created. Electrons can only flow freely in materials that conduct electricity. A Conductor of electricity is a substance that allows electricity to flow […]
