Please enable it or navigate using the Home page. Electric Potential The potential of the nucleus of an atom in a molecule. The nucleus creates a positive potential. This potential is inversely proportional to the distance, r , from the nucleus. The potential is given by the equation: The "Particle in a Box" or "Muffin-Tin" model. When the positive nuclei of atoms are brought close together in a lattice their potentials combine. This in physics is called "the superposition principle." This forms a potential well or "box" where electrons become trapped. The last frame of this animation shows the fully formed box. You can click eight times on the button below the picture and see how the potentials add to form the final "potential well." The last click will trigger the entire animation.

The subject is made much more difficult by the presence of numerous misleading "Science Myths" which circulate in the popular culture, which are handed down from parents to children, and which have become so common and widespread that they even appear in science textbooks and are taught as facts in elementary school.

As I made the mistake of choosing exceedingly boring sudjects to study just because they were easier (and there was no option to study computing), I am now trying to releive the boredom by revising physics through html coding. I am studying the WJEC syllabus, which I have transcribed below, as I revise sections and compile the pages I will turn the relevent section into a url.

Extractions: BACK Historical Beginnings of Theories of Electricity and Magnetism Michael Fowler U Va Physics The first records of electricity and magnetism An early Greek word for the sun - hlector - pronounced "elector" - was also used to describe amber, because of its sunshiny color. Amber is the fossilized resin of a now extinct coniferous tree, almost all of it comes from the Baltic region in Northern Europe. Of course, this is the stuff that preserves insects from millions of years ago. It was greatly prized in the early world as jewelry, and used as such in Greece from the earliest recorded times. Amber came to be called "electron" by the Greek classic writers, but this term also referred to native gold and silver-gold alloys (same color). First scientific-type explanations The first discussion that begins to look like a scientific explanation I can find is in Lucretius, On the Nature of Things ( De Rerum Natura ). Lucretius was born in 98 B.C. and died in 55 B.C. or so, but he was summarizing the views of Epicurus (342 - 270 B.C.), himself a follower of Democritus. They all believed everything to be made up of atoms, Democritus thought the atoms followed natural laws, but Epicurus thought they could be deviated a bit by free will. They all thought the soul too was made of atoms, which fell apart at death so there was no afterlife, and if there were gods, they didnt concern themselves with us. Anyway, back to magnets. Lucretius states (in describing a loadstone attracting a ring of iron): " ..it must needs be that there stream off this stone very many seeds or an effluence, which, with its blows, parts asunder all the air which has its place between the stone and the iron. When this space is emptied .. atoms of the iron start forward and fall into the void, all joined together .. the ring itself follows .. with its whole body." In other word
Electrogravity Physics First, read a paper that details the nature of a unique electrical field with Hereis a direct quote from his book Lectures on physics , chapter 1211 http://www.electrogravityphysics.com/
Extractions: Within these web pages I hope to take you on a journey that will show a novel and simple understanding of the nature of gravity. First, read a paper that details the nature of a unique electrical field with similar properties to that of gravity . Then, read about laboratory experiments, as well as observations from nature (on this page), that may confirm the existence of the electrogravity theory. Perhaps gravity is only a pseudo force? News reports about gravity "shielding" experiments, at Tampere University in Finland, show a small drop in the weight of objects placed over a special cryogenic device, as if it were shielding the object from the effects of gravity - an effect deemed impossible by most scientists. "We thought it might be a mistake", Dr. Podkletnov said, "but we have taken every precaution". Yet the bizarre effects persists.
Extractions: Let water power your mobile phone: scientists discover new source of electricity Sunday 19 October 2003 A new way of generating electricity from flowing water could mean that in the future you will never have to charge up your mobile phone again. Instead of a normal battery, mobile phones could be fitted with a battery that uses water - you just need to pressurise it regularly. Research published today by the Institute of Physics journal, Journal of Micromechanics and Microengineering reveals a new method of generating electric power by harnessing the natural electrokinetic properties of a liquid such as ordinary tap water when it is pumped through tiny microchannels. The research team from the University of Alberta, Edmonton, Canada, have created a new source of clean non-polluting electric power with a variety of possible uses, ranging from powering small electronic devices to contributing to a national power grid. The key to electrical power generation is to create a sustainable electrical charge separation. The physical phenomenon involved in this research is the charge separation that occurs at solid-liquid interfaces due to the dissociation of the solid. As a result, the surface becomes charged and opposite-charged ions in the liquid are attracted to it; while like-charged ions are repelled, resulting in a thin liquid layer with a net charge. This region, known as the Electric Double Layer (EDL), ranges from several nanometers to a few micrometers thick, but is the primary mechanism for charge separation.

Extractions: Hydrolic analogy of electricity Electrical question: A long time ago, when I was in the Marines studying electronic repair, one of my instructors poses the following question... "If electricity flows in a manner similar to water, why is it then that the electrons don't spill out of the outlets in a room and drown us? Or is that where we get static electricity? Just think of the implications... We would have to go around grounded, or at the very least, wearing garments made of insulated materials. Hmmmm... David James Thurber wrote a very funny story about his great-aunt, who believed (among other strange things) that if a socket didn't have a plug in it, all the electricity was spilling on the floor. (If I remember correctly) She would stalk around the house, plugging things into open sockets and crying 'AH-HA' each time. Picking huckleberries A friend of the family went camping not too long ago. The mountains of Idaho, Washington and Montana are filled with huckleberries this time of year, so she was told to bring something to collect the fruit in. She brought the vacuum sweeper. When asked what she was going to plug it in to, she answered, "A current bush." Jan Kucera: kuc@fce.vutbr.cz G. Westinghouse History
Extractions: BHS Staff Mr. Stanbrough Physics "Most people who haven't been trained in physics probably think of what physicists do as a question of incredibly complicated calculations, but that's not really the essence of it. The essence of it is that physics is about concepts, wanting to understand the concepts, the principles by which the world works." - Edward Witten (1951 - ) I see Physics 1 students for 4 - 4.5 week cycles of 85 minute periods. I try, with limited success, to divide the course as follows: Semester General Topics Text Chapters Mechanics Light I try to stress Scientific Method and how science works (and sometimes doesn't work) in this course. Not many physics students will become professional scientists, let alone physicists, but it is vitally important that, as citizens, they have a reasonably sophisticated idea of how science works. Mechanics is the soul of physics. We begin with kinematics in one- and two-dimensions ( projectiles ), proceed through
