The Night Sky
The Night Sky Long ago, people looked into the night sky and wondered what they were looking at? How far away are those twinkles in the sky? Could they all be stars, or maybe, could they be something else? What makes certain lights brighter than others, and how does distance affect their intensity? These questions and other interesting facts will be reviewed in the following pages. One of the most common curiosities regarding the night sky is distance, which can be very hard to determine. Becau...

Our Solar System, The Sun And Its Planets Has Not Always Been There.
Our Solar system, the sun and its planet's has not always been there. It is nearly five billion years ago, and there is no solar system, no planets, moons, no sun. Instead there is a big cloud of dust and gas called a nebula. This cloud has been slowly twisting for more than 10 billion years, held together by it's own gravity. Then a star explodes......WOW!! its a super nova.... The blast pushes the gases of our nebula together. That strengthens the gravitational pull of those gases even more a...

In The Eight Fold Path Of Yoga Meditation Is The Eighth Step (Smith, 1
In the eight fold path of yoga meditation is the eighth step (Smith, 11). Once here a Yogi must become more aware and more sensitive to what is within themselves (?Meditation?). ?A Yogi must first lose themselves here to find peace with themselves? (Smith, 11). The armor that a person has built around themselves throughout their lives must be lost and they have to see themselves clearly (Smith, 19). Meditation begins with concentration (?Meditation?). In concentration meditation a Yogi must foc...

Ptolemy
Ptolemy Introduction In ancient times there were many great ideas which began to shape the way man perceived his environment. However, there were few minds who were able to put all of these ideas together. One of these minds belonged to Claudius Ptolemy, or just Ptolemy as he is commonly referred to. We know almost nothing of the chronology of Ptolemy's life, and we don't even know his birth or death dates. We do know, though, about his ideas in several fields, which include geography, astronom...

The Worlds Natural Resources Are Being Consumed At An Alarming Rate. A
The world's natural resources are being consumed at an alarming rate. As these resources diminish, people will be seeking alternative sources by which to generate electricity for heat and light. The only practical short term solution for the energy-crisis is nuclear power.

Why Nuclear Fusion Is So Cool....... For A Fusion Reaction To Take Pla
Why nuclear fusion is so cool....... 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 ...

SOLAR ENERGY -- THE ENERGY OF THE FUTURE? About 47 Per Cent Of The Ene
SOLAR ENERGY -- THE ENERGY OF THE FUTURE? About 47 per cent of the energy that the sun releases to the earth actually reaches the ground. About a third is reflected directly back into space by the atmosphere. The time in which solar energy is available, is also the time we least need it least - daytime. Because the sun's energy cannot be stored for use another time, we need to convert the suns energy into an energy that can be stored. One possible method of storing solar energy is by heating wat...

History Of Physics
History Of Physics Physics began when man first started to study his surroundings. Early applications of physics include the invention of the wheel and of primitive weapons. The people who built Stone Henge had knowledge of physical mechanics in order to move the rocks and place them on top of each other. It was not until during the period of Greek culture that the first systematic treatment of physics started with the use of mechanics. Thales is often said to have been the first scientist, and ...

Nuclear Energy And The Environment
Nuclear Energy And The Environment Nuclear Energy and the Environment In our society, nuclear energy has become one of the most criticized forms of energy by the environmentalists. Thus, a look at nuclear energy and the environment and its impact on economic growth. Lewis Munford, an analyst, once wrote, Too much energy is as fatal as too little, hence the regulation of energy input and output not its unlimited expansion, is in fact one of the main laws of life. This is true when dealing with nu...

Comets
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...

Evironmentalism

New laws like the 1963 Clean Air Act and the 1974 Safe Drinking Water Act forged new ground in political environmentalism. Social phenomena like Earth Day, organized by Dennis Hayes in 1970, and the beginning of large-scale recycling, marked by Oregon's 1972 Bottle Bill, have help change the way Americans think ab...

Nucleosynthesis
Nucleosynthesis The big bang which created the universe, only created the elements Hydrogen (H) and Helium (He) and possibly a very small amount of Lithium (Li). However, a glance at the periodic table of the elements shows that today (some 15 billion years after the big bang) there are at least 108 known elements. Every atom of every element heavier than Li has been produced since the big bang! The factories which make these elements are stars. Nucleosynthesis or the synthesis of nuclei, is the...

Saturn
Saturn Saturn is the second largest planet and sixth from the sun. Saturn is most known for its rings, first seen in 1610 by Italian scientist Galileo and identified as rings by Dutch astronomer Christian Huygens in 1655. The rings consist greater than 100,000 single ringlets. It is the most oblate planet because of the rapid rotation of the planet, which flattens Saturn at the poles by about 10%. Its composition is mostly composed of hydrogen and helium. It is mostly liquid, with a small rocky ...

There are many sources of energy that that are used for transportation, heat, light, and the manufacturing of goods of all kinds. The development of science and civilization is closely linked to the availability of energy in useful forms. The seven main energy sources are fossil fuels, hydroelectric, solar power, win power, geothermal, nuclear power, and b...

Supernovas
Supernovas A supernova is a STAR that explodes. It suddenly increases in brightness by a factor of many billions, and within a few weeks it slowly fades. In terms of the human lifespan, such explosions are rare occurrences. In our Milky Way galaxy, for example, a supernova may be observed every few hundred years. Three such explosions are recorded in history: in 1054, in 1572, and in 1604. The CRAB NEBULA consists of material ejected by the supernova of 1054. Such materials, known as supernova r...

Neutrinos And Gamma Rays
Neutrinos and Gamma Rays Emission of a beta particle produces an energy change in the nucleus of an atom. The energy change that is observed, however, does not add up to satisfy the Law of Conservation of energy. The conservation law can be balanced if another particle, called the neutrino is part of this process. In the time it takes to read just this sentence, more than a billion of them will have passed unnoticed through the reader's body. Neutrinos may account for an appreciable portion of ...

The Greenhouse Effect
The Greenhouse Effect The greenhouse effect is an increase in the atmospheric temperature caused by increasing amounts of greenhouse gases. These gases act as a heat blanket insulating the Earth's surface absorbing and trapping heat radiation which normally escapes from the earth. They include carbon dioxide, water vapor, methane, nitrous oxide, CFC's, and other halocarbons. The earth's atmosphere goes through two processes constantly. Global cooling is the first process. This process uses the c...
