Simple Relativity\n\nAlbert Einstein's 1905 paper "On the Electrodynamics of Moving Bodies" introduced the special theory of relativity. Special relativity considers that observers in inertial reference frames, which are in uniform motion relative to one another, cannot perform any experiment to determine which one of them is "stationary". This is known as the principle of relativity. While this principle was not new to Albert Einstein's work, he found that including electromagnetism in this principle required a new formalism with many surprising consequences. In particular, it required the speed of light in a vacuum to be the same for all these observers, regardless of their motion or the motion of the source of the light.\n\nOne of the strengths of special relativity is that it can be derived from only two premises (although Albert Einstein did not derive it this way):\n\nThe speed of light in a vacuum is constant (specifically, 299,792,458 meters per second). \nThe laws of physics are the same in any inertial frame of reference. This means that the laws of physics observed by a hypothetical observer traveling with a relativistic particle must be the same as those observed by an observer who is stationary in the laboratory. \n\nGeneral relativity\n\nGeneral relativity was developed by Einstein in the years 1911 - 1915. General relativity is a geometrical theory which postulates that the presence of mass and energy "curves" spacetime, and this curvature affects the path of free particles (and even the path of light). It uses the mathematics of differential geometry and tensors in order to describe gravitation without the use of the force of gravity. This theory considers all observers to be equivalent, not only those moving with uniform speed.

I used to be the same way but I love teaching so much I majored in it anyways. The way I fixed my problem is I go to class with about 10 different ways to explain one thing. I try each way untill everyone gets it. Everyone usually understands by the first or second explaination. But you have to remember that nobody is the same so therefore not everyone will learn the same. You just need to be creative in your teachings so you touch everyone.

hahaha very funny i have the same physics book nice try to get someone to do ur hw.  The tarzan one is fun.  If you need help though try http://hyperphysics.phy-astr.gsu.edu/hbase/hframe.html its a pretty helpful site.

This is a very real problem and the question reflects reflects very well.\n\nFirst all all Physics is not a perfect Science it has many flaws which need to be recognized by the peers of those who are in the Profession.\nWe are generally taught by rote in school and the idea is to get you aout with a diploma as fast as possible.\nDeep thinking and digging into insight is most of the time over looked.\nThe teacher themselves were students and the way they learned is the way they teach it.Its true.\n\nIt is very difficult to teach a subject you are not really certain about.\n\nSo if you dont understand it and you repeat what you dont understand just like a parroche ,you are likely to be boring.\n\nThat is why most student hate the subject its because it is taught in a boring way. Absolutely no one likes to be subjected to "boring".\nMan! this was very dificult for me to answer.!

try talking to the teacher and see if they will prvide you with the appropriate material or at least point you in the right direction.

It would have been helpful if you had cited where Einstein said this.\n\nBut here's the deal...all motion is relative (which is why the theory is called the theory of "relativity")...relative to something or somethings.  Even things that seem to be perfectly still, like the tree in your front yard, are moving relative to something...relative to the sun, for example.  In other words, there is no such thing as an absolute motion relative to absolute zero velocity.\n\nWith all these motions (velocities) we have accelerations (v = at; a = v/t) that are, like their velocities, not absolute.  They, too, are relative.  So, as F = ma or F = mv^2/r = (m(v/t)^2)/r, the associated forces are relative.\n\nAs a consequence, there are forces acting on everything, even when none is readily apparent.  That tree, for example, has weight, which is one force.  But it also has a kinetic force (centripetal) due to its spin around the Earth and its revolution around the sun while on the Earth.  Then there's the motion of the solar system around the center of the galaxy, the motion of the galaxy through the universe, and the expansion of the universe itself.\n\nSo a single measured force is really the vector sum of all those other forces created by all those other motions.  So the notion that there is but a single force at work is "fictitious."  The good news is that the single force usually works in our observable world because we can ignore the effects of all those other forces.  But, alas, that is not the case in the relativistic world of near light speeds.  That is probably why Einstein would indicate what you claim he did.

To the extent that there was a conflict, it was resolved by Dirac. His was a quantum theory that directly included relativistic invariance. His equation is now the basis for our understanding of relativistic electrons. As of now, we don't have a way of reconciling quantum theory and *general* relativity, though.

very simple. that means ur teacher considers u as a bright student of ur class n she/he wants U to pay attention to her lecture. next time, dont look here n there, rather look straight into her face as u look at ur parents. U will start liking the subject taught, unknowingly.

As mentioned in other replies, physicists don't yet have all of the "how" questions answered. Einstein, in the General Theory of Relativity, pretty much nailed the underpinnings of the current theoretical understanding of gravity. Here is my attempt at the "nutshell." I'll start with an analogy. Let's say you are driving somewhere in the midwest or plains states--essentially flat ground, with a few rolling hills. Let's say you stop your car at the top of a slight rise. As you look around you, you see flat land in every direction. You're sitting on essentially a two-dimensional plane. Taking your foot off the brake, you notice the car starting to roll forward. Your initial observation about the 2-dimensional "space" you were sitting on isn't quite accurate. The 3rd dimension (altitude) has come into play, and gravity is pulling your car into the swale. What Einstein said (and how he came up with this back in the early 1900's is incredible) was that our THREE dimensions are really a slightly inaccurate description of the world (and universe) we inhabit. A fourth dimension, time, is part of the "fabric" of our surroundings. As in the case of that slight "warp" in the 2-dimensional farmland that led to a noticeable effect on your car, Einstein said that warps in the space-time continuum are experienced as gravity. As you know, Einstein was into the "energy = mass" thing big time, and you know that mass is tied up with gravity as well. If you want to get more cozy with these related concepts, I strongly recommend David Bodanis' book, "E=mc2: A Biography of the World's Most Famous Equation" -- available as a "BooksOnTape." It's exciting, full of cool anecdotes about the heroes of 20th century physics, and... NO MATH, just concepts. Best of luck!

It's a good question, and I'm not really sure of the answer.  It may have something do do with the fact that some people are talented and motivated to be teachers, some are talented and motivated to be physicists, and there's no apparent reason to suspect a broad overlap of the two.  I've had several physics professors who are obviously physicists first, and teachers just because its part of their job description.  \n    \nOn the other hand, what is the 'easy way' to learn physics?  If you  want an overall aesthetic appreciation of the subject, listening to or watching some of the Feynman Lectures will do the trick (I recommend this, you may be able to find them for free online).  But if you want to be able to DO physics, you HAVE to learn the math involved; physics is inextricably linked to mathematics.  \n\nOne problem I see is that teachers do not provide enough opportunities for student feedback.  Most physics curricula are rigid, and alot of teachers (unfortunately) just try to push through the course, without stopping to check if everyone is on board.  And oftentimes it seems like they just don't care.  Everyone learns subjects differently, and physics is no exception.  Teachers ought to respect this in and out of the classroom.\n\nA guy named Paul Hewitt wrote a textbook and made some lecture videos called 'Conceptual Physics' that profess to be an alternative to the standard rigorous mathematics of college physics classes.  I've seen some of the videos.  They're good...but they're still physics lectures. \n\nPractical advice:  Work problem sets out with a friend, or see a tutor.  A different perspective helps fill in alot of the gaps.  \nAlso, post questions in yahoo! answers and other forums.  An army of sad losers is waiting to help.

it is a conception of Space, made not only of 3 dimension, but 4. The fourth is Time. The relativity equations are made in this 4 dimension Space-time "Space".\nThe idea was not from Einstein, but he was the one who hd spread it.

Explain that to your professor and ask for an extension

Sorry, but with the time you spent typing these questions you could of looked them up in your physics book or googled them.  Sometimes getting others to do your leg work isn't always the best answer to a problem.  Good Luck in your new class!

The theory of relativity is being used in Fermi lab, U.S. to "create" either energy or new matter from energy.  Newton's laws only define motion, but they do not explain why some of the mysteries of the solar sytem or the universe occur.  With Einstein's theory, however, these mysteries become clearer.  We understand more why they occur this way and can predict how much energy is being "created" by calculating for how much matter is "lost."  Fermi lab is working to create anti-matter, combine it with matter to create energy, and utilizing the energy into more matter -- it's one of their big projects.  I'm sure they're testing for more than that, but it's the overview of what they are doing.
