Donneida Thomas December 12‚ 2013 Physics pd. 11 Bombing of Innocent Civilians The former president‚ Harry Truman had to make one of the most crucial decisions of his life. On August 6‚ 1945 during World War II‚ he decided to drop the atomic bomb on two cities in Japan. The first bomb that dropped on Hiroshima was nicknamed “Little Boy”. The explosion wiped out 90 percent of the Hiroshima and immediately killed an estimation of 80‚000 people; thousands more people would later die of radiation

Atomic weapons are similar to poison gas – both are barbaric.The U.S.A. should not shock the world with such a weapon. What we have to understand is that current bombing campaign against Japan has brought the country just about to its knees. The atomic bomb will

Niels Bohr and Albert Einstein are names anyone who has taken a basic physics course is familiar with. Posters of Albert Einstein can be easily encountered hanging on walls‚ with quotes that often do not contemplate any scientific content. These scientists are two of the most influential personalities of modern physics‚ although little is talked about the respectful rivalry that took place between the two over nearly 30 years regarding physics’ most revolutionary branch of quantum mechanics. In his

Composition II “You Have Atomic Bombs‚ but We Have Suicide Bombers” In Rohde’s article we learn of his experience as a hostage in Afghanistan and Pakistan. He explains the Islamic cultures and values‚ but shows us his view on them. Their cultures have some similarities‚ but more differences. We both have religions‚ but Americans approach their religion differently and less violently. America’s whole reality and country differs greatly from the Taliban’s society. The Taliban’s reality differs

1.1 The atoms‚ during bond formation‚ may lose or gain electrons (valence electrons) in order to achieve a stable state‚ or technically speaking‚ a stable electron configuration. Usually metal atoms lose electrons and non-metals gain electrons in order to achieve electron stability. When dealing with bond formation (Ionic bonding for example) we need to analyse the outer shell of the atom. Metals usually present 1‚ 2 or 3 electrons in their outer shell therefore they have to give them away to achieve

The Atomic and Nuclear Structure of an Atom The atom has three main components the protons‚ neutrons‚ and electrons. The protons and neutrons make up the nucleus‚ while the electrons are found outside the atom’s nucleus. Each component of an atom has a charge to it. The protons have a positive charge. The electrons have a negative charge‚ and the neutrons have a neutral charge. The atoms also have a charge. For example hydrogen can be negative‚ positive or neutral. These are called

Democritus Democritus ( 460 a.c.– 370 a.c.) was an Ancient Greek philosopher born in Abdera‚ Thrace‚ Greece. He was an influential pre-Socratic philosopher and pupil of Leucippus‚ who formulated an atomic theory for the universe. His early deductions about the composition of the basic component of nature led him to believe in unseen and uncuttable particles ‚ called atomos. This Greek philosopher wondered how he could be sitting in one part of his

1. a) Democritus reasoned that if matter could be infinitely divided‚ it was also subject to complete disintegration from which it can never be put back together. However‚ matter can be reintegrated. b) In Greek‚ the prefix "a" means "not" and the word "tomos" means cut. Our word atom therefore comes from atomos‚ a Greek word meaning uncuttable. All matter is composed of atoms‚ which are bits of matter too small to be seen. These atoms CANNOT be further split into smaller portions. 2. At
