Gravity, Electricity, and Magnetic Force.

Extracts from this document...


Albert Einstein is one of the greatest physicists we know.  He created the theory of relativity, and then worked to discover a theory of which unites all theories and rules of the world but couldn’t make it.  Today, many physicists and mathematicians are trying to find the theory and we are almost there but still farther from it. The theory of everything, scientists’ dream, is called the grand unification theory.  

        Whether you do or don’t, I think most people have thought about how we are created, where the world comes from, or this kind of questions.  These are all toward to the question about the beginning of the universe at the end.  The origin of the universe is always wondrous and mysterious.  It is the last question we can solve, maybe, because no one saw and experienced the creation from nothing.  However we, physicists, challenge this and try to figure out it.  The grand unification theory is scientists’ dream.

        Isaac Newton, Albert Einstein, and James Clerk Maxwell are the most well-known physicists.  They discovered many great theories and these discoveries developed physics and still apply to our world.  Moreover these functions seem to relate each other.  

        In our real world, there are basically 4 big forces of nature, which are Gravity, Electromagnetic, the Strong Force, and Weak Force.Gravity is a force act between all mass in the universe.  Electromagnetic

As you see, you can tell there is a similarity very easily.  Therefore we can assume that there is one basic relationship between all of them, and this is the idea of the grand unification theory.

Isaac Newton discovered the unification of terrestrial and celestial mechanics, which is called Universal Gravitation today.  James Clerk Maxwell succeeded the unification of electricity, magnetism and light, which is called Electromagnetism today.  Albert Einstein developed the idea of space-time geometry and the theory of gravitation.  And recently the theories of weak force and electromagnetism are unified by Glashow, Weinberg and Salaam in 1979, and this theory is known as Standard Model of particle physics.  The weak and electromagnetic interactions have been unified under electroweak theory (the Nobel Prize for 1979). Grand unification theories attempt to treat both strong and electroweak interactions under the same mathematical structure.


The features of unification of these 4 forces are:

1.1.    Through the application of rotational dynamics and gyroscopic analysis the GFT unifies Newton's Gravitational Force Law, Coulomb's Law, and Ohm's Law.  

2.2.    It derives the masses of both the electron and proton and other elementary particles.  

3. 3.    It provides a logical model of quark aggregation and formation.  

4.  4.    It establishes the basis for the existence of fractional charges as posited in the Standard Model.

5.  5.    It provides a classical foundation for Quantum Mechanical principles through the use of Kepler's Third Law.

Finally, it is still hard to reach the grand unification theory, but it is appearing to us step by step.  There is another theory called M theory, and it is an advantage of the string theory, and that may help to solve problems.  

In conclusion, the grand unification theory is still undefined, and it needs time to find that still.  However if we could get to the goal, finding a rule for everything, we could approach the origin of the universe, because at the beginning, only one thing was born, and then it started to spread out.  The idea of grand unification theory is very scientific and may be unusual to general people; however, as people start thinking about it because they wondered how we are created and what happened at the beginning.  This is a general and unconcluded question but most people have thought about.  Such an idea that the great physicist Albert Einstein started is still in mystery.  However we are approaching the goal.  Originally there was only one power and everything has been spread and separated from the one existence or nothing.  To figure out the origin of universe and what happened then is our dream and the unification theory is the hope of us to see the truth, and it is not too far from us now I believe.

    his aim to humiliate Hooke in public because of his opinions was abnormal. However, perhaps because of Newton's already high reputation, his corpuscular theory reigned until the wave theory was revived in the 19th century. Newton's greatest achievement was his work in physics and celestial mechanics, which culminated in the theory of universal gravitation.

    Generally though, slow-fissionable isotopes are more fissionable than fast-fissionable isotopes for neutrons of all energies. A general trend among the elements is that the ratio of neutrons to protons in an atomic nucleus increases with the element's atomic number (the number of protons the nucleus contains, which determines which element it is).
