Pay relativity for airline staff working out of different countries - is it fair?
Q. I just read a newspaper article about a NewZealand airline that flies to China. It employs some Chinese nationals as FAs (who are based in China). These people get only a quarter of the basic salary (and about half the travel allowance) that is paid to FAs based in NZ because of 'market relativity' - ie) the cost of living is much cheaper in China. Do you think this is fair?
Asked by Just Lovely - Sat Mar 15 05:48:16 2008 - - 6 Answers - 0 Comments
A. Well, the problem is that we are in an International world and our normal ways of operating don't really apply. The problem is that while it may appear unfair, the Chinese staff are getting a decent salary for their country. If we stick to exact equivalent pay then the Chinese staff will not get as many opportunities. On the other hand, the airlines will favour less qualfied staff chinese staff over better NZ staff because of the pay difference. The real problem is that a Chinese airline could use all Chinese staff (most with University degrees) pay them much less than the NZ airline and undercut the foriegn airlines. Change involves pain and we have to endure this pain while working for a better tomorrow.

What are some ways that Einstein's theory of relativity be tested?

I would like to know about the general idea of relativity and all the possible methods to test it. If you don't mind, I would like to know the "big" list of possible experiments because I would like to choose which one is the most possible and reasonable one for me to do. Thanks!

A. Special or General relativity? "all the possible methods to test it." That's a big list. --- Why put big in quotes? You don't believe me? Unfortunately, due to the nature of Einstein's theories of special and general relativity, most experiments require very large speeds or very massive objects--qualities the general public doesn't encounter everyday. Perhaps you could try to replicate the Michelson-Morley experiment to test the second postulate of special relativity. Im sure there are design plans or already built Michelson's interferometers lying around online.

What explanation does general relativity provide for gravity?
Q. What explanation does general relativity provide for gravity? Gravity is a result of curved spacetime. Gravity is directly proportional to mass. Gravity is inversely proportional to radius. All of these are correct.

A. In GR, gravity is a result of the curvature of space-time. Unaccelerated objects moving through flat space-time move in straight lines, but in curved space-time they move in curves. Pick up "Gravitation" by Misner, Thorne and Wheeler for some relatively accessible explanations of this.

A. I haven't read Ellis's book, but I have read Rindler's and I strongly recommend it. Rindler does a great job of giving the reader an intuitive view of things and presents some pretty interesting problems. If you like the mathematical side of GR, particularly geometry, you will like this book. He goes over the geometry of curved spaces in depth which is good if you want to understand the beauty that is GR. The SR section of the book is great. He derives the Lorentz transformations from scratch and based on Einsteins Relativity principle, and Einsteins law of light propagation. He also introduces 4-vectors which remove a lot of the tedium form SR calculations. All in all a great book.

Is there a contradiction between free will and relativity?
Q. My physics knowledge is imperfect so this may be rubbish but... Since relativity states that time in a subjective concept depending on your position then arguably you could say the future has already happened but we're looking in the wrong place. Does this then imply that whatever we choose to do is already set and thus we cannot truly have free will? If yes or no then why?

A. "Already" set? if the future has "already happened," then when exactly IS the "present"? Point of view matters - that's the point of relativity. So no, there is no contradiction. Point of view can never escape the present moment. In a sense, point of view *is* the present moment. And we can't escape having a point of view. Free will is part of it's "what it's like" to be a person. It's not a true or false thing about the universe. There is no new info about it from relativity.

Then read do Carmo's "Differential Geometry of Curves and Surfaces". From there, you could look at Do Carmo's graduate level book on Riemannian geometry. I believe his Riemannian geometry book is the most easily accessible compared to other books on this topic.

Asked by spark - Fri Jun 19 09:14:39 2009 - - 1 Answers - 0 Comments
A. Time dilation is the effect caused on the passing time felt by an object when its speed increases and approaches the speed of light. As the speed increases so does the time slow down and at the speed of light itself the time dilation has reached such a significant magnitude that it stops passing. Thus a photon of a beam of light occurs simultaneously everywhere, as far as it can tell! Simultaneously means at the same time so its relativity for different speeding objects makes no sense.

How has Albert Einstein's theory of relativity change the world?
Q. How has his theory of relativity change the world or shape the world?

A. this is a broad question. So my answer is broad too. "The world would not be the same as what we know today." We would not understand light as what we know today. We would still believe that speed of light is infinite, which now we know that it is finite.

Is there a relationship between the atom bomb and Einstein's theory of relativity?
Q. I know that Einstein designed the atomic bomb that was ulimately dropped on Hiroshima and Nagasacki. Is there a connection between the theory of relativity and the atom bomb?

A. A very indirect one I suppose. You can use the equivalence of energy and mass to calculate the amount of energy released in a nuclear reaction. energy released = c^2 * (mass reactants - mass products) Einstein didn't really do any work on the bomb, but he did write a now-famous letter to the president alerting him of the possibility of such a bomb.

Can you answer my General Theory of Relativity question?
Q. Describe three key concepts of General Theory of Relativity and when what it written and by whom?

A. Einstein's general theory of relativity deals with gravity and its effect on space. He states that a massive body cause the curvature of space and light or bodies moving in space will follow this curvature. Proof was provided in an experiment during an eclipse of the sun, the position of a star which was known to be behind the sun at the time of the full eclipse could be seen from Earth, as the light from the star bent around the sun.
