  • Archimedes Was A Greek Mathematician And Scientist He Was Born In Syracuse, Sicily In The Year 287 Bc He Was Educated In Alex - 724 words
    Archimedes was a Greek mathematician and scientist. He was born in Syracuse, Sicily in the year 287 B.C. He was educated in Alexandria, Egypt. Due to the lack of information about Greek mathematics, many Greek mathematicians and their works are hardly known. Archimedes is the exception. Archimedes was very preoccupied with mathematics. For instance, he often forgot to eat and bathe because of his always wanted to solve problems. He found areas and volumes of spheres, cylinders and plain shapes. He showed that the volume of a sphere is two-thirds of the volume of the smallest cylinder that can contain the sphere. Archimedes was so proud of this concept that he requested that a cylinder enclos ...

  • I Want To Be A Scientist - 667 words
    I Want To Be A Scientist When I was a little girl, my best friend's dad was a neurologist. He tricked us with color and number tests and other brainteasers. I was fascinated by how my brain reacted to the games, and ever since, I have wanted to study the brain. Later, as a high school sophomore, I still focused on being a doctor, and that year I was deemed worthy of an internship at a local hospital. So, the following summer, I gave up late mornings and relaxing by the pool to get up early and help doctors at the hospital. I had originally applied for a neurological internship, which the program did not offer, so I was shuffled into working with doctors in the maternity ward and the nursery. ...

  • Scholarship Essay Desire To Become A Scientist - 443 words
    Scholarship Essay - Desire to become a Scientist Ever since I could remember, I have always wanted to become a scientist. That craving to understand the mysteries of the universe has been one of the most passionate desires of mine since I was a toddler. I can still recall laying in my bed, staring at the ceiling, and wondering why some people had crooked teeth while others didnt. The question How? always echoed within my thoughts. When I entered school, science and mathematics quickly became one of my most favored subjects. In my mind, they were the most logical and precise. The answers they provided were based on fact, not human intuition. As I matured, I grew to enjoy the systematic mechan ...

  • The Amateur Scientist - 768 words
    The Amateur Scientist The Amateur Scientist I was on my way to work, when I started to read this interesting story and I don't deny that I was a little sceptical in the beginning. But the more I read, the more I wanted to know about this man and his unique ways to define Science. I finished reading it in about 15 minutes, it literally sucked me in. This is an attempt to analyze and explain to the "audience," what my personal point of view is regarding this great genius, great mind, great scientist Richard Feynman. Defined by his colleagues as the "The brightest mind since Einstein," he explains how he used everyday tools to make scientific discoveries. How he describes his methods in a simpl ...

  • 22399 - 1,303 words
    2/23/99 The Hindenburg Disaster Count Ferdinand Von Zeppelin and his crew operated their first airship nearly one hundred years ago. Airships are big controllable balloons, also known as dirigibles. There are three classes of airships, rigid, nonrigid and semirigid. Rigid airships (zeppelins) use framework in the interior to keep their shape. Semirigid airships are a combination of framework and gas pressure to maintain their shape. Nonrigid airships (blimps) rely solely on air pressure to keep their form. They are all propelled with engines, use rudders and elevator flaps for steering and have a gondola where passengers travel. The pride of the zeppelin works was a rigid airship which was o ...

  • A Look At Public Key Encryption - 1,210 words
    A Look at Public Key Encryption Encryption is the process of disguising information by transforming plain text into gibberish, or ciphertext, which cannot be understood by an unauthorized person. Decryption is the process of transforming ciphertext back into plaintext that can be read by anyone. Example of encryption can be found in history, for example in the era of the Cold War, the Solviet Union and the United States would send electronic messages to one military point to another, encrypted. If the enemy intercepted the message, they would have to crack this message to get the information. Typically when governments used encryption they used a very complex method of encrypting messages.

  • A Short History Of Antisemitism In Germany - 779 words
    A Short History of Anti-Semitism in Germany A Short History of Anti-Semitism in Germany The Second World War has left an unmistakable impression on the whole of Europe that will never be forgotten. Whether visible to the naked eye, or hidden in the consciousness of its people, the war has scarred Europe indelibly. Historically, the foremost recognizable perpetration against Europeans was Adolf Hitlers "Final Solution to the Jewish question". This sophisticated operation of systematic mass execution was calculated, organized, and carried out with such horrifying efficiency that only a madman could have been responsible for such an act, and Hitler was indeed mad. However, Anti-Semitism had bee ...

  • Acid Rain - 1,731 words
    Acid Rain Introduction: What Causes Acid Rain? One of the main causes of acid rain is sulfur dioxide. Natural sources, which emit this gas, are Volcanoes, sea spray, rotting vegetation and plankton. However, the burning of fossil fuels, such as Coal and oil, are largely to be blamed for approximately half of the emissions of this gas in the world. When sulfur dioxide reaches the atmosphere, it oxidizes to first form a sulfate ion. It then Becomes sulfuric acid as it joins with hydrogen atoms in the air and falls back down to earth. Oxidation occurs the most in clouds and especially in heavily polluted air where other compounds such as ammonia and ozone help to catalyze the reaction, changing ...

  • Adult Illiteracy - 3,413 words
    Adult Illiteracy Learning to read is like learning to drive a car. You take lessons and learn the mechanics and the rules of the road. After a few weeks you have learned how to drive, how to stop, how to shift gears, how to park, and how to signal. You have also learned to stop at a red light and understand road signs. When you are ready, you take a road test, and if you pass, you can drive. Phonics-first works the same way. The child learns the mechanics of reading, and when he's through, he can read. Look and say works differently. The child is taught to read before he has learned the mechanics the sounds of the letters. It is like learning to drive by starting your car and driving ahead. ...

  • Aids - 1,103 words
    Aids Aids Acquired Immune Deficiency Syndrome (AIDS), suppresses the immune system related to infection with the human immunodeficiency virus (HIV). A person infected with HIV gradually loses immune function along with certain immune cells called CD4 T-lymphocytes or CD4 T-cells, causing the infected person to become vulnerable to pneumonia, fungus infections, and other common ailments. With the loss of immune function, a clinical syndrome (a group of various illnesses that together characterize a disease) develops over time and eventually results in death due to opportunistic infections (infections by organisms that do not normally cause disease except in people whose immune systems have be ...

  • Aids - 1,443 words
    AIDS Gonzales 1 The Acquired Immune Deficiency Syndrome (AIDS) was first discovered in 1981 as a unique and newly recognized infection of the body's immune system (Mellors 3). The name AIDS was formally know as GRIDS (Gay Related Immune Defiance Syndrome). The first case of AIDS was discovered in Los Angeles, where scientists from the CDC (Center for Disease Control) were called in on a half dozen cases. The CDC was convinced what they were seeing was a new strand of virus. None of the staff members had ever seen a strand of virus that could do so much destruction to the immune system like this one did. Many theories about this disease were in question. Many scientists believed it originated ...

    Air Pollution Acid rain is a problem that has plagued earth for years. It is poisoning our waters, animals, plants, soil, and more. It is a problem that can not be ignored or it might have catastrophic results on our environment. Acid rain is caused by air pollution, which is due to man-made actions. Scientists have discovered that air pollution from the burning of fossil fuels is the major cause of acid rain. Power plants and factories burn coal and oil, which is used to produce the electricity we need to heat and light our homes and to run our electric appliances. We also burn natural gas, coal, and oil to heat our homes, and our cars, trucks, boats, and airplanes use gasoline to run, whic ...
