Despite their diplomatic and mercantile qualities‚ the Assyrians had the most capable and savage military of their time. Through technological advancements and sheer ruthlessness‚ they built the largest empire the ancient world had ever seen. One of the most important technological advancements they made was using iron for weaponry instead of bronze. Iron has a few advantages over bronze. One being that because bronze is an alloy of copper and tin whereas iron is a naturally occurring element‚ iron

THE STRUCTURE OF SILICON DIOXIDE Silicon Dioxide is commonly found in our daily lives- but what exactly is it? Silicon Dioxide (SiO2)‚ or Silica‚ is the most abundant compound of silicon found in the Earth’s crust‚ as well as a widely found oxide. Formed when silicon is exposed to the oxygen in the atmosphere‚ it is a giant covalent molecule with strong electrostatic forces of attraction between the adjacent non-metal oxygen and silicon atoms. Silicon Dioxide occurs in 13 different structural modifications

Regina May P. Hinagdanan 10-SCB Physics Reaction Paper Is nuclear power plant really that dangerous? It is true that many people have varying opinions about having nuclear power plants and developing nuclear energy. I‚ myself‚ see it as a good alternative source of energy while my brother sees it as a weapon for mass destruction. Nowadays‚ people are easily swayed by the reports of the media. Indeed‚ most of them are true but some of them tend to be a bit exaggerated. The article pointed

The Significance of Dropping the Atomic Bomb Paul Warfield Tibbets Jr.‚ who dropped the atomic bomb died in 2007. However‚ the dispute of his action continues and the atomic bomb does not disappear with his death. The main argument people are talking about is that whether it is a right decision for the us to use atomic weapons on japan to end World War 2. It is true that the atomic bomb totally destroyed two cities of Japan‚ causing millions of civilians dead directly. Moreover‚ the nuclear radiation

For a considerable length of time‚ researchers have been searching for purported "glueballs." Now it appears they have been found finally. A glueball is an extraordinary molecule‚ made up altogether of gluons - the "sticky" particles that keep atomic particles together. Glueballs are insecure and must be identified in a roundabout way‚ by investigating their rot. This rot process‚ then again‚ is not yet completely caught on. Teacher Anton Rebhan and Frederic Brünner from TU Wien (Vienna) have now

The dynamo theory explains the mechanism by which a celestial body generates a magnetic field. For a long time‚ it has been suggested that Earth’s magnetic field would eventually weaken. The field can change over time and may even occasionally flip‚ causing the north to become the south and vice versa. Now‚ new research‚ published on July 28th in Nature‚ states that Earth’s weakening magnetic field is actually a sign that another flip is to be anticipated. It is important to understand Earth’s magnetic

Chemistry Changes Everything: ¹ᶟ¹I - Iodine¹ᶟ¹ An isotope is two or more forms of an element where the nuclei of the element has more neutrons than protons and normally each element only has one stable isotope of the element. Changing the neutrons in the atom also changes the atomic mass but not chemical properties. Radioisotopes are radioactive versions of an isotope where the atom or element has an unstable nuclei therefore emitting radiation. An unstable nuclei is created when there is either

As for EDF‚ it has developed a "behavior module" for specific outages and a fire simulation to integrate the procedures: "As the date of the nuclear fleet of 70-80 years‚ it is facing many retirements that replaces a lot of young people. And like that was not well anticipated‚ companionship is very short. We try to as qualitative as possible alternative way of expert knowledge in serious games. ". But beyond the good or bad assumed applications‚ serious games‚ which participates in the advent of

Chromium has an atomic number of 24 and is located in the 6th group‚ 4th period of the periodic table of elements. Chromium is a metal and can be identified by its atomic symbol of Cr. Chromium is a hard and brittle metal‚ making it hard to bend as it would break if one tried to do so. Chromium is also a shiny and lustrous metal with a grey color to it. Chromium may also be identified by its high melting and boiling point and can prove to be very useful in everyday lives. Chromium was first discovered

A nuclear weapon is commonly defined as a device‚ which uses a nuclear reaction for destructive means. There are six different types of nuclear bombs. The two main types of nuclear weapons: atom bombs and hydrogen bombs. The hydrogen bomb is the most powerful‚ destructive bomb of all. In this essay I’m going to give a brief history of the hydrogen bomb‚ the chemistry behind the bomb‚ and how much destruction the hydrogen bomb can do. After the Soviet Union’s atomic bomb success during the cold war
