On October 9, 2013, a Nobel Prize was awarded to 2 physicists on the account of the Higgs boson, aka the “God Particle”, that was discovered last year. The Higgs Boson is the particle that would explain what scientist have been scratching their head over for years, how all matter in the universe gets its mass. In the 1960s, Peter Higgs and other physicists proposed a theory on how particles acquire mass. The theory suggests that everything in the universe is in what’s called a Higgs energy field, in which particles move around and attract Higgs Bosons, giving them their mass. Particles that would attract more Higgs Bosons would have more mass, whereas particles that draw less Higgs Bosons would have less mass. For physicists, finding the Higgs Bosons would explain the mystery of mass that has been existent in the Standard Model of fundamental particles. Located underground in Geneva, Switzerland, the Hadron Collider worth 10 billion dollars, 17 miles in length, and is 328 ft. underground has been smashing together protons at high speed by scientists hoping to find evidence of the Higgs Boson. According to the theory that everything in the universe is in the Higgs field, by smashing protons together the physicists believed that they might be able to knock off a small part of the Higgs field, making the Higgs Boson visible to sensors, before turning into particles due to its instability. The Nobel Prizes awarded to Peter Higgs and Francois Englert, the people who…
the video, which is essentially the only justification for money spent to the big science project.
I believe that the main task of this story - it's popularization for usual people of elementary particle physics as a science.
When I been at the Institute, I studied physics of elementary particles, so most of the terms I was know.
The first thing that impresses - scale. Especially the number of people who worked on this project and dimension of the collider. 27 kilometers of scientific equipment:…
The Higgs Boson, commonly called “the God particle” is part of the standard model of particle physics. "The God particle" comes from the title of Leon Lederman's book on the topic and stuck although it has nothing to do with God. The Standard Model was put together in its final form in the 1970’s with the confirmation of the existence of quarks and consists of the simplest explanations for the behavior of particle physics. In the early 1960 the first high energy particle collisions were experimentally…

All matter is made up of atoms
Atomos /Atoms- small, invisible, indestructible and physically indivisible particles which are infinite in number
Issac Newton 1704
Defined the laws of gravity and motion
Newton's law of gravity-all objects attract everything other object in the universe with gravitational forces.
Atoms are solid, hard, impenetrable, moveable particles
Newton’s laws of gravity and motion -atoms are held together by opposing forces.

There are 5 points in the particle theory
Matter is made up of particles
All particles move according to how much heat is added
All particles attract
All particles are made of different substances if they aren't alike
There are spaces between the particles
Development of the Atomic Theory
Atom – The smallest particle into which an element can be divided and still be the same substance. Element – A pure substance that cannot be separated into simpler substances by physical or chemical means. Atoms make up elements. Elements are made of only one kind of atom. Elements combine to form compounds. All matter is made of elements or compounds, so all matter is made of atoms. Atoms are so small that, until recently, no one had ever seen one. But ideas, or…
and to discussing their properties (i.e. density, compressibility, etc...)
The particle model for matter states that all matter is made of particles which are moving all the time.
In solids they vibrate in place, a solid holds its shape and volume.
In liquids the particles can move all through the liquid, it pours, A liquid holds its volume but takes the shape of the container.
In a gas the particles are moving fast. A gas will spread out to fill any container, a gas does not hold its shape…
Wave Particle Duality
Wave particle duality that all particles exhibit both wave and particle properties. A central concept of quantum mechanics, this duality addresses the failure of classical concepts like particle and wave to fully describe the behaviour of quantum-scale objects. The idea of duality originated in a debate over the nature of light and matter that dates back to the 17th century, when Christiaan Huygens and Isaac Newton proposed opposing theories of light, one theory was that…
