Perception: Seeing Is Believing - UFOs
.... life.
It seems certain scientists have come up with other hypotheses
concerning UFO's. While all astronomers yearn for a concrete explanation on
UFO's, their beliefs on their origin contrast. Many looking for a more
scientific definition disregard UFO's as nothing more than a mere
misinterpretation of a plane, weather balloon, or meteor. Some have gone so far
as to say that specific witnesses to UFO's have seen nothing more than a
hallucination and "wanted" to see a UFO so their minds adapted that idea .....

Oil is running low on the Earths surface and many oil platforms are
becoming more and more important. Already 30% of oil used comes from those
platforms. In another few years it will become about 50%.The Military could use

The Future Of NASA
.... pacemaker is a form of life-support on
spacecrafts, helping astronomers' hearts pump while they are outside of the
Earth's atmosphere. It is used, on Earth, for those who's hearts have problems
with pumping blood. Pens that write upside-down are used in space, where there
is no gravity and writing with pens would otherwise be impossible. They are
convenient tools on Earth when we are trying to write on vertical surfaces. A
zero-gravity training system is used to help astronauts become more comfortable .....

.... types of polyps. The names of these three polyps
are: dactylozooid, gonozooid, and gastrozooid. The polyps are the parts that:
capture prey, digest prey, and reproduce. The dactylozooids have cells called
nematocysts(3). The nematocysts release a toxin(4) into anything that they come
into contact with. The gastrozooids then attach to the dead/stunned victim, and
spread over it. They digest it, and transfer food to the rest of the man-of-war.
Last, the gonozooids create other polyps. The means by which t .....

liquid-propellant rocket on March 16, 1926. This was a simple pressure-fed
rocket that burned gasoline and liquid oxygen. It traveled only 56m (184 ft) but
proved to the world that the principle was valid. Gossard Died August 10, 1945.
Gossard did not work alone, he was also in partnership with a Russian theorist
named Konstantin Tsiolkovsky. Tsiolkovsky was born on September 7, 1857. As a
child Tsiolkovsky educated h .....

an important fact was established: uranium is the last and heaviest element
present on earth. This was demonstrated by Dimitri Mendeleev in his famous
perodical classification of the elements by chemical properties and increasing
atomic mass. Experimentation with uranium lead to many discoversies such as the
X-ray by Wilhelm Röntgen, on November 8, 1895.
Wilhelm Röntgen, was awarded the first Nobel prize in 1901 for the development
of the X-ray. Uranium is weakly .....

folded sheets of rock called pahoehoe. Stickier lava cools into rough, jagged
sheets of rock called aa. Pahoehoe and aa cover large areas of Hawaii, where
the terms originated. The stickiest lava forms flows of boulders and rubble
called block flows. It may also form mounds of lava called domes.
Other lava formations are spatter cones and lava tubes. Spatter cones
are steep hills that can get up to 100 feet high. They build up from the spatter
of geyser-like eruptions of thick lava. Lava .....

A Discussion On Earthquakes
.... discuss how earthquakes are formed and
occur, how scientists can more accurately predict the arrival of earthquakes.
Before contemplating how earthquakes might possibly be prevented, it is
essential that the process and formation of and earthquake be understood.
Earthquakes are caused when the earth's crustal plates move, rub, or push
against each other. The earth's crust (the outer layer of the earth) is made up
of seven major plates and approximately thirteen smaller ones. The name plate
is used to de .....

Could The Greenhouse Effect Cause More Damage?

The grid is divided into ten sections. Each of the ten sections covers
thirty square yards of the meadow. The infarared lamps will heat every other
section by 2.5 degrees. The unheated sections in between allow researchers to
compare the efects of the lamps with the regular state of the meadow.
One time a week, Harte will take gas samples from buckets turned upside
down for ten minutes at a time on both the heated and unheated strips through
fitted nipples at t .....

Acid Rain Legislation

water in the atmosphere to form what is known as acid rain.
The main reason that has prompted legislation of industrial emissions
from governments is because of the negative effects they can have on the
environment. Acid rain is harmful to the environment because of it's low pH.
It can harm the biotic components of earth, and also the abiotic components.
It's high acidity degrades soil to the point where it cannot support any type of
plant life. Trees in forests are killed over lon .....

chemicals drift, they may change again. They may react with other chemicals in
the air. When sulfur dioxide combines with water, the result is sulfuric acid.
When nitrogen oxide gas combines with water, the result is also another acid.
When the clouds releases rain or other precipitation, the acid goes with it.
This is called acid rain.
The level of acid is measured in pH levels. The pH scale begins at 0
and ends with 14. A re .....

ACID RAIN

The threat posed by acid rain is not limited by geographic boundaries, for
prevailing winds carry the pollutants around the globe. For example, much
research supports the conclusion that pollution from coal-powered electric
generating stations in the midwestern United States is the ultimate cause of the
severe acid-rain problem in eastern Canada and the northeastern United States.
Nor are the destructive effects of acid rain limited to the natural environment.

Acid Rain

lead could go into our drinking water. It is hard to determine where acid rain
may fall next, because the wind from a pollueted area could carry pollution to
another area and the acid rain could fall there. The regions effected more by
acid rain is large parts of eastern North America, Scandinavia, and central
Europe. In alot of places acid rain isn't a probelm because some soils can
neutralize the acid and it doesn't effect the crops. Areas more sensitiv .....
