General Relativity

The History of Classical Gravitational Theory and General Relativity In the beginning scientists and religious men of their era tried to explain the universe both biblically and scientifically. One of the foremost Greek scientists was Aristotle; taught by Plato, that the circle and sphere are the two most perfect shapes in a 2 and 3 dimensional universe, Aristotelian system placed Earth at the center of the universe; and all other heavenly bodies revolved around the earth in crystalline...

General Relativity

General relativity is a theory of gravitation that was developed by Albert Einstein between 1907 and 1915. According to general relativity, the observed gravitational attraction between masses results from their warping of space and time. By the beginning of the 20th century, Newton's law of universal gravitation had been accepted for more than two hundred years as a valid description of the gravitational force between masses. In Newton's model, gravity is the result of an attractive force between...

Tok Essay: "Only Seeing General Patterns Can Give Us Knowledge. Only Seeing Particular Examples Can Give Us Understanding." to What Extent Do You Agree with These Assertions?

“Only seeing general patterns can give us knowledge. Only seeing particular examples can give us understanding.” To what extent do you agree with these assertions? In 2007, approximately 1.58 million scientific research papers were published, far more than one could possibly read in a lifetime. However, when I visited CERN last year, I was told that all of our present understanding of physics could be summarised in a few equations: General Relativity, describing gravity; and the Standard Model...

Hans Albert Einstein, was born in Berne, Switzerland. 1905 His Special Theory of Relativity is born and he applies his theory to mass and energy and formulates the famous equation e=mc2. Einstein has four papers published in the Annalen der Physik, the leading German physics journal. 1905 is known as Einstein's "Wonderful Year". 1907 Einstein begins applying the laws of gravity to his Special Theory of Relativity. 1908 Albert Einstein becomes a privatdozent (an associate professorship) at the...

Einstein

of the people who don't do anything about it.” “The World As I See It” Who was Albert Einstein? While most do not understand his work, everyone knows that Einstein’s impact on the world is astonishing. Many people have heard of his general theory of relativity, but few know about the intriguing life that led Einstein to discover what some have called the greatest single achievement of human thought. Einstein’s life, which led to his discoveries and papers, led to an amazing legacy which impacted...

History of Motion

did with Copernicus and Galileo, it was recognised as great achievement, and this scientific progression led to many discoveries that would contribute to the world we live in today. Albert Einstein’s Theory of Special Relativity Albert Einstein’s Theory of Special Relativity, published in 1905, is a theory of measurement that only applies to uniform velocities. According to his theory, Einstein states that all motion is relative and every concept involving space and time are also relative, therefore...

The ‘Hole’ Argument Against Substantivalism

Argument Against Substantivalism The ‘hole’ argument against substantivalism is a great argument created by Albert Einstein out of desperation when his general theory of relativity ran into obstacles. The ‘hole’ argument says that if the general theory of relativity is true and substantivalism is true, then for any model of the general theory of relativity representing a physically possible universe, there is a hole diffeomorphism of that model which represents a physically possible universe that is observationally...

General Physics Q&A's

 Reading Assignment #1: Vector Analysis Textbook Sections that I read: 2.1-3 Important Concepts: An interaction between two objects can be described and measured in terms of two forces. The force is a push or either a pull. There are two types of forces. #1 is a long range force and this force does not require the objects involved to be touching each other. An example of this is when you are holding a magnet away from a refrigerator and you are able to feel the magnetic pull. #2 is a contact...

be observed if the hypothesis is correct. The consequences should be absent if the hypothesis is not correct. 5. Test predictions Do experiments to see if the consequences you predicted are present. 6. Draw a conclusion Formulate the simplest general rule that organizes the hypothesis, predicted effects, and experimental findings. But scientifically speaking, a theory is a synthesis of facts and welltested hypotheses. Science is a system by which we discover and record physical phenomena...

A Brief History of Stephen Hawking

held by Isaac Barrow, and then in 1669 by Isaac Newton. Stephen Hawking has worked on the basic laws which govern the universe. He showed that Einstein's General Theory of Relativity implied space and time would have a beginning in the Big Bang and an end in black holes. These results indicated it was necessary to unify General Relativity with Quantum Theory. One consequence of such a unification that he discovered was that black holes should not be completely black, but should emit radiation...
