For those who spend their lives working to prevent and end wars‚ whether and how war itself can be justified must be an urgent question. Of course‚ war’s justification is an ancient tradition. Bizarrely‚ Just War theory was formulated within the Christian church‚ whose founder chose a donkey instead of a war horse and taught his followers to overcome evil with good. Not only is the theory still mainstream among churches but‚ as Dan Smith‚ head of an important NGO working for conflict transformation

Kevin Li Mrs. Baldwin Honors Chemistry 3 November 2012 Historical Development of Atomic Structure Over the many years of the world’s history‚ there have been numerous developments and discoveries pertaining to atomic structure. Each of these breakthroughs gradually led us—step by step—to a deeper understanding of what makes up each and every atom. Because of this‚ our perception of an atom’s structure today is vastly different from the first idea of an atom’s structure from many centuries

Ernest Rutherford | 18 | 10 | References | 21 | INTRODUCTION It is quite remarkable to know that the work of scientist hundreds years ago lies at the heart of our understanding of the structure of atom. New Zealand scientist Ernerst Rutherford was the first to show that the atom is the building block of all matter that consists of a positively charged nucleus surrounded by tiny negatively charged electrons. The extraordinary achievements of these scientists have been instrumental development

IF YOU WERE PRESIDENT HARRY TRUMAN‚ WOULD YOU HAVE MADE THE SAME DECISION AS HE DID‚ WITH DROPPING THE ATOMBOMB ON HIROSHIMA? The 6th of August 1945 was a day that people will always remember with terror. On this day‚ an atomic bomb was used by the U.S. against Japan‚ in the city of Hiroshima. This was the first time in world history. Before this sad event‚ Japan and the U.S. were having conflicts with each other because Japan tried to invade parts of Europe and the Pacific. In an attempt stop Japanese

Isotopes‚ sub-atomic particles and relative atomic mass Sub-atomic particles A subatomic particle is a particle smaller than an atom: it may be elementary or composite. In 1905‚ Albert Einstein demonstrated the physical reality of the photons‚ hypothesized by Max Planck in 1900‚ in order to solve the problem of black body radiation in thermodynamics. In 1874‚ G. Johnstone Stoney postulated a minimum unit of electrical charge‚ for which he suggested the name electron in 1891. In 1897‚ J. J. Thomson confirmed

Was America justified in dropping the atomic bomb on Japan? The dropping of the atomic bomb on Japan ended world war two. The decision to do so was solely that of the Commander in Chief of the Armed Forces‚ Harry S. Truman. As President Truman had to ask himself whether or not it was justifiable to use a weapon of untold destructive force. The answer would change the world. I. The Dropping of the Atomic Bomb A. How was the atomic bomb created? 1. The atomic bomb was created

history. Currently‚ the atom is known as the basic unit of a chemical‚ but there was a time when that was not known among scientists. There were multiple scientists that contributed to the creation of the first Atomic Theory: Democritus‚ Antoine Lavoisier‚ Joseph Proust‚ and John Dalton. Dalton took the information that he had taken from the three scientists prior to him and put everything into one theory. The Atomic Theory is the most well-known and accurate theory we know right now. Later on in

The Progress of the Atomic structure Different theories about the atomic structure were introduced over time. These theories changed as a result of development of different experiments. Leucippus was the first to introduce the theory of atomism‚ however he didn’t write about his theories in detail. However‚ Democritus‚ his student wrote about the theory of atoms in detail. He theorised that everything was composed of atoms and that atoms are solid and indestructible. He also had a theory that

The invention of the atomic bomb certainly brought extreme fear into Canadians’ lives after revealing its astonishing power through the massive destructions done at Hiroshima and Nagasaki. Although most people did not speak of this fear but it can be clearly seen throughout the cold war when the arms race between the two super powers at the time‚ the United States and the Soviet Union‚ split the world into two halves. On one side‚ there was the communist countries allied with the Soviet Union‚ and

Nuclear Bombs August 6th‚ 1945‚ the US drops the first nuclear bomb in combat over the city of Hiroshima‚ in Japan. This date is a huge part in our history because no weapon of such mass destruction has ever been used in combat like this. Three days later another nuclear bomb is dropped over Nagasaki‚ as soon as the bomb detonated around 80‚000 people died almost instantly showing the sheer power the bomb. A nuclear bomb has never been used in combat since then‚ but nuclear development has created
