Physics for Idiots - Particles and Forces Throughout the whole of the known universe there are only 2 types of particle. Particles that make up matter, and particle that carry force. They are the only 2 types found so far. Now you may be thinking that, yes there may only be two categories but I bet they're filled with hundreds of different subgroups and types. Thankfully this isn't the case, particles follow specific rules and once you known them everything gets a lot easier. Fermions Fermions is the title that refers to all particles that make up matter. Another thing that distinguishes Fermions is the particles spin. Another thing that distinguishes Fermions is the fact that they obey the Pauli exclusion principle. Leptons Leptons are a collection of 6 sub atomic particles, 2 types for each flavour. Quarks Quarks are the other type of matter particle along with the leptons. Hadrons Physicists seem to love their labels and groups. The reason you get groupings of 2 or 3 quarks is because of their colour. Bosons Forces Only 3?

One of the main reasons for the study of chemistry to be difficult has always been the difference in the way things seem to work from the point of view of the atom and the view from human being size. A human is usually between one and two meters tall. An atom is similarly usually between one and two Ångstroms in diameter. One vrumschk says to another, "Hey, Snerbert! "You've been inhaling comet dust," says Snerbert, "There is no way to see anything that small because the frequency of electromagnetic radiation we can detect is far too large to make a picture of anything that small. "I've been watching it for a few billion years and it has changed since that time. Michael Treidl
What is a plasmon? Continuing my series of posts trying to describe condensed matter topics in relatively non-technical language.... As I've mentioned before, in condensed matter physics, we tend to give particle-like names (that is, ones that end in "-on") to excitations of systems that have well-defined particle-like attributes, like momentum, energy, and angular momentum (such as spin). Plasmons are another example of this, and lately they've become extremely fashionable because it's increasingly clear that they can be technologically useful. A plasmon is a collective excitation of the electronic "fluid" in a piece of conducting material, like ripples on the surface of a pond are a collective mode of the water molecules of the liquid. These electronic ripples can have a well-defined wavelength (which quantum mechanics tells us is related to their momentum). Plasmons have gotten so much attention lately for several reasons.
Optics basics: surface plasmons | Skulls in the Stars My goal in my "basics" series of posts is not just to introduce the most elementary topics in optical science, but also to give background on some of the more advanced concepts for future reference. Much of my own research, and consequently my blog interests, center on nano-optics -- the study of the behavior of light on scales much smaller than the wavelength of light -- and one specific aspect of nano-optics that has grown tremendously in importance over the past ten years is the concept of a surface plasmon. Broadly speaking, a surface plasmon is a traveling wave oscillation of electrons that can be excited in the surface of certain metals with the right material properties. Because a plasmon consists of oscillating electric charges, they also have an electromagnetic field associated with them which also carries energy. A simple schematic of a surface plasmon is shown below¹: It is important to note that not all metals can support surface plasmons. 1) Field enhancement. \(E=pc\). ³ D.
10 Strange Things About The Universe Space The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Theoretically, the lowest temperature that can be achieved is absolute zero, exactly ? One of the properties of a negative-energy vacuum is that light actually travels faster in it than it does in a normal vacuum, something that may one day allow people to travel faster than the speed of light in a kind of negative-energy vacuum bubble. One prediction of Einstein’s theory of general relativity is that when a large object moves, it drags the space-time around it, causing nearby objects to be pulled along as well. Relativity of Simultaneity Since this extra dimension is so small, only tiny objects, such as particles, can move along it. Antimatter Retrocausality
Boolean Logic, Gates, and Computer Circuits Boolean Logic, Gates, and Building Computer Circuits (revised 02/06/2008) Since computers are built out of bi-stable electronic circuits, the two-value system of Boolean logic is used in circuit design. Boolean logic has two values: true and false. Boolean Logic : There are two Boolean values true and false which are sometimes represented as 1 (true ) and 0 (false). A simple Boolean expression is an expression that evaluates to true or false. example : (a Compound Boolean expressions are formed out of simple Boolean expression using Boolean operations Common Boolean operations are AND, OR , NOT , and XOR (eXclusive OR) In Python use and , or and not, True and False In C++ && denotes AND, || denotes OR and ! Defining AND, OR, NOT and XOR The fourth Boolean function, XOR (exclusive or) is sometimes included with the other three. Evaluating Compound Boolean Expressions Example: A leap year is a year which is divisible by 4 and not a century year (i.e. Boolean Operator Precedence Rules a | b | result
