Shrinking proton puzzle persists in new measurement - physics-math - 24 January 2013. A puzzle at the heart of the atom refuses to go away. The most precise measurement yet of the proton's radius confirms that it sometimes seems smaller than the laws of physics demand – an issue that has been hotly debated for two years. The latest finding deepens the need for exotic physics, or some other explanation, to account for the inconsistency. "If we were in a hole before, the hole is deeper now," says Gerald Miller of the University of Washington in Seattle, who was not involved in the new measurement. The saga of the proton radius began in 2010, when a group led by Randolf Pohl at the Max Planck Institute of Quantum Optics in Garching, Germany, determined the width of the fuzzy ball of positive charge – and found it was smaller than had been assumed. Previous teams had inferred the proton's radius, which is impossible to measure directly, by studying how electrons and protons interact.
One method uses the simplest atom, hydrogen, which consists of one electron and one proton. How to Build Simple Transistor Circuits. A compilation of important assorted transistor simple circuits to build has been included here.

Elastomers. Keywordscrosslinking, entropy Elastomer is a big fancy word, and all it means is "rubber". Some polymers which are elastomers include polyisoprene or natural rubber, polybutadiene, polyisobutylene, and polyurethanes. What makes elastomers special is the fact that they bounce. But just saying "they bounce" is kind of vague. But why? Putting Entropy to Work for You! Entropy is disorder. But now pull on the piece of rubber, and everything gets upset. Now when you let go of this rubber sample you've been stretching, the molecules will quickly go back to their tangled and disordered state.
Glass or rubber? Of course, not all amorphous polymers are elastomers. One Molecule Can Do a Lot To help elastomers bounce back even better it helps to crosslink them. But this makes elastomers hard to recycle. Watch Bleach Episode 256 Online. How to solve sudoku puzzles @ paulspages.co.uk.

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 ? 273.15°C, where the motion of all particles stops completely. 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 This is similar to arranging tiles evenly on a floor. Succeed in Understanding Physics by Ron Kurtus - School for Champions. Physics is a branch of Physical Science that is concerned with the study of the physical properties of matter. The subject can be divided into three main areas: Classical Physics, Relativity, and Quantum Mechanics. The material here will concentrate on classical or everyday physics.
The knowledge of Physics is important for the development of the products we use. It is also an interesting and exciting subject of value in many walks of life. The purpose of these free online lessons is to give you a start at improving your scientific knowledge of physics that will help you become a champion in the field.

Density Fluids. Welcome to Einstein Online - relativity and more! — Einstein Online. 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.
The simile here isn't too far off, because like water, the electronic fluid in a metal is pretty close to incompressible. These electronic ripples can have a well-defined wavelength (which quantum mechanics tells us is related to their momentum). 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.

The voices of the people have in these days brought about revolutions in a number of countries. I think it is time for us as well to start a revolution to get rid of the picture of the gravitational force as a consequence of a curved spacetime. Can one imagine a more unphysical definition?
I have found that the gravitational force is a function of the gradient of the speed of light caused by a balanced exchange of energy between matter and ether. Rotating masses (mass particles) seem to generate dipole radiation. Dipole radiation is a known phenomenon in an electrical context. Etherus_short (pdf 500k) Etherus (pdf 1385k) boris.lindblom@tele2.se. 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? Atomic properties menu.

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. You might say that in one length dimension there is a difference in size of E10 (1010) between humans and atoms.
What if there were a creature that was E10 larger than humans? One vrumschk says to another, "Hey, Snerbert! "I've been watching it for a few billion years and it has changed since that time.
