- Albert Einsteinman Of Vision - 1,905 words
Albert Einstein-Man Of Vision Albert Einstein: Man of Vision Albert Einstein, perhaps the greatest mind ever to have walked the face of the earth, was born on March 14, 1879 in Ulm, Germany. As a boy, he hated school, and felt that the regimented and repetitive nature of schooling in Germany at that time had any promise of helping his future. He did not do well in school, mainly because he did not care to learn what was being taught to him. While he seemed to be a bright child, his schoolwork did not interest him, but at the same time the simple compass that his father owned fascinated him. Albert constantly harassed his father and his Uncle Jake with questions concerning how the compass wor ...

Astronomers Part One Brief Descriptions of the Following Astronomers: Walter Baade : Baade was a German-born American, whose work gave new estimates for the age and size of the universe. During the wartime, blackouts aided his observatons and allowed him to indentify and classify stars in a new and useful way, and led him to increase and improve Hubble's values for the size and age of the universe (to the great relief of geologists.) He also worked on supernovae and radiostars. Milton Humason : Humason was a colleague of Edwin Hubble's at Mt. Wilson and Palomar Mtn. who was instrumental in measuring faint galaxy spectra providing evidence for the expansion of the universe. Jan Oort : In 1927 ...

- Origins And Bibliography Of The Big Bang Theory - 2,022 words
... to all the laws of physics, such as electromagnetism. In any freely falling frame, therefore, the laws of physics should (at least locally) take on their special relativistic forms. This postulate is called the Einstein equivalence principle (EEP). One consequence is the gravitational redshift, a shift in frequency f for a light ray that climbs through a height h in a gravitational field, given by (delta f)/f = gh/cc where g is the gravitational acceleration. (If the light ray descends, it is blueshifted.) Equivalently, this effect can be viewed as a relative shift in the rates of identical clocks at two heights. A second consequence of EEP is that space-time must be curved. Although thi ...

- The Age Of The Universe - 1,639 words
The Age of the Universe INTRODUCTION: The goal of the project is to find the age of the universe according to the theory that there were equal amounts of the two uranium isotopes U235 and U238 at the time of the Big Bang. At present, there are 137.7 U238 atoms for each atom of U235. We know that the half-life of U235 is 0.71 billion years, and the half-life of U238 is 4.51 billion years, we used this information to determine the age of the universe. We started by looking at the problem mathematically and then after figuring out the age of the universe with the above information. We proceeded to look for other sources of information about the age of the universe with supporting data. The two ...

- The Beginning Of Time - 1,308 words
The Beginning Of Time The Beginning Of Time There was a period in history when the beginning of the world in which we live in was a expressed through legends and myths, now, through the use of increasingly advanced scientific equipment we can see that the universe is more vast and complex than ever imaginable. The purpose of this paper is to show some of the modern beliefs regarding the beginning of the universe by finding the answer of these questions. What are the commonly excepted theories of the evolution of the universe? What is meant by the Big Bang Theory and how does it work? How our planet and solar system developed from The Big Bang? This paper will use scientific data to base the ...

Universe Not so much a theory of the universe as a simple picture of the planet we call home, the flat-earth model proposed that Earths surface was level. Although everyday experience makes this seem a reasonable assumption, direct observation of nature shows the real world isnt that simple. For instance, when a sailing ship heads into port, the first part that becomes visible is the crows-nest, followed by the sails, and then the bow of the ship. If the Earth were flat, the entire ship would come into view at once as soon as it came close enough to shore. The Greek philosopher Aristotle provided two more reasons why the Earth was round. First, he noted that Earths shadow always took a circu ...
