ATOMIC PHYSICS The nuclear atom All matter is made up of atoms which consist of a central nucleus‚ surrounded by electrons. Inside the nucleus are protons and neutrons. Particle Relative mass Charge Location Proton 1840 + Nucleus Neutron 1840 0 Nucleus Electron 1 - Outside nucleus Proton or atomic number (Z) This is the total number of protons in the nucleus of an atom. Nucleon or mass number (A) This is the total number of protons and neutrons in the nucleus of an atom. Note: a nucleon

Christopher Gooden Dr. Jan Yarrison-Rice Physics 101 5 April 2005 Physics in Sports When many people think of sports‚ the topic of physics doesn ’t always come to mind. They usually don ’t think about connecting athletics with academics. In reality math‚ science‚ and especially physics‚ tie into every aspect of sports. Sports are a commonality that brings nations together‚ Soccer‚ known as football to most of the world‚ is said to an unspoken language‚ which unties people from different lands

The Importance of Physics to Society Physics - the study of matter‚ energy and their interactions - is an international enterprise‚ which plays a key role in the future progress of humankind. The support of physics education and research in all countries is important because: 1. Physics is an exciting intellectual adventure that inspires young people and expands the frontiers of our knowledge about Nature. 2. Physics generates fundamental knowledge needed for the future technological advances

Lamia Doueihi 2/27/15 AP European History Newtonian Physics and Darwinian Biology on European Culture Sir Isaac Newton and Charles Darwin were both influential men who had impacted European culture during their respected eras‚ and in later eras. Newton was an English physicist and mathematician. During the Enlightenment‚ his Newtonian physics impacted European culture with his effects on science. Charles Darwin was an English naturalist and geologist. One of his greatest impacts on European culture

Sub Atomic Particles and the New Large Hadron Collider Many non-scientists still believe that the atom is the smallest element in this world. Also most scientists use to believe that. However‚ since the 1960’s‚ scientists discovered that the theory is not true. They succeeded at finding that there is smaller particles than the atom using early colliders. Scientist used to use older and smaller machines to find smaller particles than the atom‚ and most of the older colliders are still in use

Strings‚ Strings‚ Everything is made of Strings The Holy Grail of physics is to explain all the four forces of nature and matter/energy (they are both the same thing) into a single equation. This theory of everything will reveal everything about the universe‚ most importantly‚ how it began. So far the only game in town is string theory. String theory is a purely mathematical theory that makes the bold claim that all matter and force particles are made of unimaginably tiny strings that vibrate in 10 dimensions
