The Creation of the Universe
This paper will go over the creation of the universe. There are many theories about this
issue. I will briefly summarize a few of them, and then give whatever evidence is available for or
against each.
There are many theories regarding the creation of the universe, for example, there is an
ancient Egyptian legend that says that Osiris Khepera created himself out of a dark, boundless ocean
called "Nu". Then out of this ocean, he created the universe. I will be writing about these theories:
The Big Bang theory is what most people believe, also there is a theory called "Steady State", which
is the opposite of the Big Bang theory. There is the theory of an "Oscillating Universe", which is sort
of a compromise between the Big Bang theory, and the Steady State theory. There is also the
religious theory, in which God created everything.
There are a lot of different theories regarding the creation of the universe. It is a very
controversial topic, because most theories don't follow the story of Genesis in the bible. There is the
"Big Bang" theory, the "Steady State" theory, and the religious theory. The theory that best explains
creation is the Big Bang theory,

Solar Oven
SOLAR OVEN
Why it will work:
It will work because the cold air under the box will be separated by
four (4) wood pegs. The black, non-glossy paint will attract heat, rather
than reflect it. The glass, double panel, will allow heat to pass through, but
not allow it to escape. The charcoal cubes and shavings will absorb the heat
in the box and store the excess heat allowing the flow to continuously warm
the oven. The tin foil will reflect heat and subsequently heat up the oven.
The polyurethane material will trap the heat inside the oven. The mirrors
will help the heat stay inside the box.
Materials used:
Shoe Box
Tin Foil
Sheets of Glass
Charcoal Cubes and Shavings
Scissors
Glue
Knives
Polyurethane
Non-Glossy, Black Spay Paint
Four (4) Wood Pegs
Mirrors
Sealer

Copernicus
Copernicus' work on planetary motion stood an a very high mathematical level for his times. His
theory explained how all the celestial bodies move around the Sun. It took Nicolaus 30 years of mathematical research to form a theory about planetary motion. The three most popular instruments which Copernicus used were quadrant, armilla, and triquetrum. All furnish some measure of the position of the heavenly body. It took an endless amount of mathematical calculations to come up with the Copernicus' theory. He had to find out how fast the Earth spins around the Sun, and how far the Sun is. He also had to calculate the length of the orbit of the Earth. People use math in every walk of life. In our days everything is related to math, and Copernicus used his knowledge of mathematics to provide the human kind with an important discovery.
Only a small amount of people are interested in Copernicus' work. If it wasn't for Copernicus' love of scientific truth, the people would not know that the Earth spins around the Sun, and not the other way around. That's way we should live with the knowledge that someone spent 30 years researching and finding the truth, and that man was Nicolaus Copernicus.

Asteroid Defense
Asteroid Defense
When it comes down to developing a way to defend the entire planet from destruction I am all for it. A large asteroid or comet hitting the earth is not a common occurrence. But it has happened many times before and when it does happen again the asteroid may wipe out all life, including humans. If our government did develop an anti-asteroid defense system, it would not only have to protect our country, but the whole planet.
If we had such technology we would first have to be very sure it would work.
We wouldn't want to shoot a nuclear weapon at an asteroid just to have it break into multiple pieces and have those pieces raining down on Earth. One of the most important parts of defending our planet would be to find and chart every asteroid that could threaten us. That would be a very tedious and never ending job, but is necessary for the defense system to work. It would do us humans no good to have some sort of defense against asteroids if we don't know when they will strike.
So after thinking about an anti-asteroid defense system, I think that our government should look into constructing one. When one thinks about what an asteroid could do to our planet it is usually a very scary thought. In the past we have been very lucky with where asteroids have hit our earth. Back in 1908 in the Tunguska region of Siberia, an object from space hit there causing miles of forest to be devastated. If that same object had hit New York, it would have probably been like a 20 megaton bomb going off in Times Square. That would have completely altered history. What makes it worse is that it is thought that a small comet hit in Tunguska. What if a huge comet had hit there? These examples are very good reasons why I think that humankind needs to come up with a way to stop asteroids or any other type of object that could kill off all life on earth.

Aristotle
Aristotle
Aristotle was a Greek philosopher and was born in 348 B.C. He studied under another philopsopher Plato and later tutored Alexander the Great at the Macedonian court. In 335 B.C. he opened a school in the Athenian Lyceum. During the anti-macedonian agitation after Alexander's death Aristotle fled to Chalcis where he later died in 322 B.C. His extant writings, largely in the form of lecture notes made by his students, include the Organum (treatises of logic); Physics; Metaphysics; De Anima (on the soul); Nicomachean Ethics and Eudemian Ethics; Politics: De Poetica: Rhetoric; and works biology and physics. Aristotle held philosophy to be the the discerning, through the use of systematic logic as expressed in Syllogisms, of the self-evident, changeless first principles that form the basis of all knowledge. He taught that knowledge of a thing requires an inquiry into causality and that the "final cause"-the purpose or function of the thing-is primary.
This is a direct quote from his works (translated):
"The highest good for the individual is the complete exercise of the specifically human function of rationality. In contrast to the Platonic belief that a concrete reality partakes of a from but does not embody it with the exception of the Prime Mover (God), form has no separate existence but is immanent in matter."
Aristotle's work was lost following the decline of the Roman Empire but was reintroduced to the West through the work of Arab and Jewish scholars, becoming the basis of medieval scholasticism.
In my opinion Aristotle was one of the greatest and most important of the philosophers and scientists of the world's history.
