Nuclear Power

Nuclear Power is undoubtedly the an incredible power, producing no carbon emissions whatsoever. The Nuclear Energy Institute (http://www.nei.org/Knowledge-Center/Nuclear-Statistics/World-Statistics) states that there are 438 nuclear reactors in 30 different countries and 67 nuclear reactors under construction in 15 countries.
Roughly 10% of the worlds energy is generated by nuclear power, but people are terrified of the potential destruction of a meltdown in a nuclear reactor.

A uranium pellet the size of a Pencil eraser produces the same amount of energy of 738 tonnes of coal. Unfortunately, nuclear reactor disasters in the past like Chernobyl and Fukushima have created a fear in many countries that refuse to allow nuclear reactors. For example, Australia has 31% of the worlds uranium and geologically stable ground, but the country has only one nuclear reactor in Sydney that produces medicine. OPAL (or Open Pool Australia Light-Water Reactor) is Australia's only functioning nuclear reactor (http://www.world-nuclear.org/info/Country-Profiles/Countries-A-F/Appendices/Australian-Research-Reactors/) produces many medical substances along with irradiating silicon. By irradiating silicon, it changes a very small amount of the silicon into phosphorous, making it significantly more conductive.

The Science of Firearms

Guns are a hot topic in USA and many other places, their destructive abilities and availability means that murders are frequent in the many places.
But, many who own guns don't even know how guns work, let alone the rest of us gun free people across the world
The basic principle behind a firearm, at least a modern one, is that a bullet or projectile is loaded into a chamber, the bulled consists of a casing a projectile and gunpowder or cordite and the casing is at the base. It is filled with gunpowder and then the projectile is loaded into the casing sitting on the gunpowder. Then, when the trigger is pulled the hammer pulls back and slams forward creating a spark, that hits the primer ,which is a small explosive, that ignites the gunpowder pushing the projectile forward at incredible speeds. the casing is then ejected, this can happen by many methods and most of these mechanisms are unique to a specific weapon manufacturers. following the ejection of the casing a spring in the magazine pushes up the next bullet ready to have the process repeated. but that is only a semi automatic weapon the most common modern firearm, There are many types of guns including; manual action firearms; that can only be fired once per equipped barrel before it must be reloaded or charged via an external mechanism or series of steps. A semi-automatic, or self-loading, firearm is one that performs all steps necessary to prepare the it to discharge again after firing—assuming cartridges remain in the weapon's feed device or magazine. An automatic firearm is one that continues to load and fire cartridges from its magazine as long as the trigger is depressed (or until the magazine is depleted).

Leonardo da Vinci

Leonardo di ser Piero da Vinci, or more simply Leonardo da Vinci, was an Italian “polymath” meaning his expertise spanned a significant number of different subject areas including; Invention, painting, sculpting, architecture, science, music, mathematics, engineering, literature, anatomy, geology, astronomy, botany, writing, history, and cartography. He has been variously called the father of paleontology (Basically the study of fossils) ichnology (the examination of footprints as fossils), and architecture, and is widely considered one of the greatest painters of all time. He is often credited with the inventions of the parachute, helicopter and tank, his genius epitomised the Renaissance.Born on the fifteenth of April 1452 in the Tuscan town of Vinci, little is known about Leonardo's early life. He spent his first five years in the home of his mother, then from 1457 he lived in the household of his father, grandparents and uncle. In 1466, at fourteen, Leonardo was apprenticed to the artist Verrocchio, and gained much of his artistic talent there.From 1476 to 1507 Leonardo put to use his existing talents and gained a many more, he studied at an art academy where he also learned of engineer and took classes pertaining to it. He wrote letters and gave gifts to a duke of Millan securing peace between Italy and Milan for the duration of the renaissangce. He designed a dome for a cathedral showing of his engendering talent and was commissioned to paint many of his most famous paintings, cementing his place in higher societyFollowing a French invasion of Italy, Leonardo and some of his closest friends fled to Venice where his renown as an engineer was put to use on a military council where he came up with some of his most radical ideas including the aforementioned tank. In 1500 he returned to Italy where he served the war mongering SON of the corrupt POPE Cesare Borgia (underlined because, POPES AREN’T SUPPOSED TO HAVE SONS [or a common whore for a wife]) as a military engineer and advisor, he retired from this position 3 years later. Following this he left the public eye and split up his recently deceased father’s estate among his brothers.From 1510 to 1516, Leonardo spent much of his time living in the Belvedere in the Vatican in Rome, under the newly elected Pope Leo X. In October 1514, King Francis I of France recaptured Milan. Leonardo was commissioned to make for Francis a mechanical lion which could walk forward, then open its chest to reveal a cluster of lilies. He spent the last years of his life, accompanied by his friends and apprentices, and supported by a pension totalling 10,000 scudi (a small fortune).Overall Leonardo pioneered many inventions and was an engineering and artistic figurehead for his time and will not soon be forgotten, whether from his paintings ideas or professions he pioneered. 

The Large Hadron Collider

The Large Hadron Collider (LHC) is the world's largest and most powerful particle collider. It’s the largest, arguably most complex facility ever built. Along with being the largest single machine in the world. The LHC has and will continue to challenge our (as a species) current idea of physics. The large hadron collider sits in The European Organization for Nuclear Research’s (CERN) accelerator complex. The LHC consists of a 27-kilometer ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way.  It first started up on the 10 September 2008, and after a closure and refit in 2013 it opened again in 2015 after being extensively upgraded, including a beam power enhancement of ~six times its original power.

Back in 2011 two teams at the Large Hadron Collider looking for the Higgs Boson announced that they had finally seen results which could suggest the Higgs Boson particle existed, The Higgs Boson is a particle that gives mass to other particles which, if real would lead to much more interesting discoveries including the source of the creation of the universe. Around Christmas that year the same teams, announced that they had finally seen results which could suggest the Higgs Boson particle existed; however, they did not know for certain if this was true. But on 4 July 2012, the teams at the Large Hadron Collider declared that they had discovered a particle to which most signs point to being the Higgs Boson. March the following year the teams had done much more testing, and announced that they were within acceptable error margin and that the new particle was a Higgs Boson.

This discovery is undoubtedly one of the most scientifically significant events in the history of the Earth.

Many people believe (or believed) that the Large Hadron Collider could set off a chain reaction that could lead to Earth's destruction. For more information check out the following link:

Nuclear Fission and Fusion

Nuclear Fission and Fusion are both forms of nuclear energy but vary on the production of such energy.

Nuclear Fission

Nuclear Fission uses either Plutonium or Uranium for fuel. Fission starts when a fast moving neutron strikes a nucleus. The whole nucleus breaks apart into two smaller nuclei. In the process of splitting several neutrons split off from the nuclei and continue the reaction. A Nuclear Reactor requires a controlled reaction. An uncontrolled reaction will lead to incredible heat being generated, and this is how a Nuclear Bomb is created. 

Nuclear Fusion

Nuclear Fusion uses Hydrogen as fuel and occurs when atoms fuse together. To start a fusion reaction, pairs of nuclei must meet so that they fuse together. When they fuse a neutron will be left over. The fused nucleus will move off at high speed producing astronomical amounts of heat. There is no radiation, but the neutrons are harmful. To make the nuclei fuse the temperature of the atoms must reach millions of degrees. 

E=mc2

Perhaps the most famous equation known to man is E=mc², but what does it actually mean?

The "E" in the equation is energy. The "m" is the change in mass and the "c" is the speed of light. Therefore the equation is, "Energy is equal to the mass of the object multiplied by the speed of light squared." An example is an object that weighs 12 grams. The equation would be 12 x 8.98755179 x 10¹⁶. This is equal to 1,078,506,219,000,000,000 joules. That is equal to 107,850,621,900,000 kilojoules or 299,585,061 Watts.
