anti-matter summary Anti-Matter Summary Introduction Ordinary matter has negatively charged electrons circling a positively charged nuclei. Anti-matter has positively charged electrons - positrons - orbiting a nuclei with a negative charge - anti-protons. Only anti-protons and positrons are able to be produced at this time, but scientists in Switzerland have begun a series of experiments which they believe will lead to the creation of the first anti-matter element  Anti-Hydrogen.The Research Ea

Nuclear / Particle Physics Effects of the Atomic Bombs on Hiroshima and Nagasaki Ever since the dawn of time man has found new ways of killing each other. The most destructive way of killing people known to man would have to be the atomic bomb. The reason why the atomic bomb is so destructive is that when it is detonated, it has more than one effect. The effects of the atomic bomb are so great that Nikita Khrushchev said that the survivors would envy the dead (International Physicians for the Pr

Notes on the lithosphere- (rock sphere) Upper most part is crust of earth. Compiled of rocks of outer crust. Outermost shell. Upper part- rocks we see at and near the earths surface. Crust is 5 to 10 km thick under most oceans and 24 to 60 km thick under the continents. The lithosphere under the crust is solid, dense material. (more dense than surface materials). Lithosphere 100-200 km. Notes on the aesthenosphere- zone beneath the lithosphere. Thick like tar. Weak because of high teperatures a

Physics ISU (a) Cathode Rays are invisible particles that are emitted from the cathode (negative end) and travel to the anode (positive end). These rays are called cathode rays because they originated from the cathode. They travel in a straight lines, possess kinetic energy (which means that they mush have some mass) they are high speed, negatively charged electrons. (b) An Electron Gun is something that 'boils' out electrons at a high temperature from the cathode and they are accelerated tow

Nuclear Power
Nuclear Power
Nuclear Power Throughout the world, energy sources are being depleted, and the search for new ways of creating power is intensifying. Nuclear power has been introduced, but has been met mostly with fear in the United States. The introduction of new technology has always created fear and apprehension among users and observers. Electricity and natural gas caused similar apprehension, as did the train, the automobile, and the airplane(R. Deutch). With these other technologies, people were willin

Muscle is the tough elastic tissue that makes body parts move All anim
Muscle is the tough, elastic tissue that makes body parts move. All animals except the simplest kinds have some type of muscle. People use muscles to make various movements, such as walking, jumping, or throwing. Muscles also help in performing activities necessary for growth and for maintaining a strong, healthy body. For example, people use muscles in the jaw to chew food. Other muscles help move food through the stomach and intestines, and aid in digestion. Muscles in the heart and blood ves

Fusion reactions are inhibited by the electrical repulsive force that
Fusion reactions are inhibited by the electrical repulsive force that acts between two positively charged nuclei. For fusion to occur, the two nuclei must approach each other at high speed to overcome the electrical repulsion and attain a sufficiently small separation (less than one-trillionth of a centimeter) that the short-range strong nuclear force dominates. For the production of useful amounts of energy, a large number of nuclei must under go fusion: that is to say, a gas of fusing nuclei

Nuclear chemistry creates many different phenomena that interest chemi
Nuclear chemistry creates many different phenomena that interest chemists, from the new chemical tools they provide to the subtle changes in chemical behaviors because of the differences in the nuclei. Nuclear chemists focus mainly on the differences and similarities of an elements isotopes, weather they are stable or radioactive isotopes. But what is nuclear chemistry? We will explore that in this paper, starting with atomic structure: what is an atom make up of, Quantum mechanics, probability
Fusion
Fusion
Fusion Fusion is a nuclear process in which two light nuclei combine to form a single heavier nucleus. An example of a fusion reaction important in thermonuclear weapons and in future nuclear reactors is the reaction between two different hydrogen isotopes to form an isotope of helium: 2H + 3H ---- 4He + n This reaction liberates an amount of energy more than a million times greater than one gets from a typical chemical reaction. Such a large amount of energy is released in fusion reactions beca

The Atom
The Atom An atom is the smallest unit of matter that is recognizable as a chemical ELEMENT. Atoms of different elements may also combine into systems called MOLECULES, which are the smallest units of chemical COMPOUNDS. In all these ordinary processes, atoms may be considered as the ancient Greeks imagined them to be: the ultimate building blocks of matter. When stronger forces are applied to atoms, however, the atoms may break up into smaller parts. Thus atoms are actually composites and not un

Fusion For centuries, humankind has looked at the stars, and for just as many years humankind has tried to explain the existence of those very same stars. Were they holes in an enormous canvas that covered the earth? Were they fire-flies that could only be seen when the Apollo had parked his chariot for the night? There seemed to be as many explanations for the stars as there were stars themselves. Then one day an individual named Galileo Galilei made an astounding discovery: the stars were repl
Fission or Fusion
Fission or Fusion
Fission or Fusion I think that right now, fission is the only way that we can get more energy out of a nuclear reaction than we put in. First, the energy per fission is very large. In practical units, the fission of 1 kg (2.2 lb) of uranium-235 releases 18.7 million kilowatt-hours as heat. Second, the fission process initiated by the absorption of one neutron in uranium-235 releases about 2.5 neutrons, on the average, from the split nuclei. The neutrons released in this manner quickly cause the

Nuclear Fusion
Nuclear Fusion
Nuclear Fusion For a fusion reaction to take place, the nuclei, which are positively charged, must have enough kinetic energy to overcome their electrostatic force of repulsion. This can occur either when one nucleus is accelerated to high energies by an accelerating device, or when the energies of both nuclei are raised by the application of very high temperature. The latter method, referred to the application of thermonuclear fusion, is the source of a lot of really cool energy. Enough energy

Comets The first written records of comets date back to nearly 3,000 years ago from China and Europe. The accounts of these comets were believed to be the causes of terrible events that occurred afterwards. In more recent times, however, astronomers have found out what they really are. A comet is basically a mixture of ices, from both water and frozen gases, and dust. They have also been given the names “dirty snowballs” or “icy mud balls.” The typical comet is less than 10 kilometers across. Th

They are elementary particle physics, superstition, mythology and fairy tales. The northern lights have filled people with wonder and inspired artists; they have frightened people to think that the end is at hand. More exact explanations of the phenomenon could not be given until modern particle physics were developed, and knowledge about details in the earth’s magneto

Nucleotides The foundation of life as we know it is composed of nucleic acids. Researchers believe that these fundamental building blocks were first formed three billion years ago when the first forms of elementary life began to appear on earth. Nucleic acids have at least two functions. The first of these functions is to serve as a means of passing on hereditary characteristics, and the second is to instruct the cells in the production of specific proteins. Nucleic acids by nature are rather c
