This is like the picture here shows: http://en.wikipedia.org/wiki/Minkowski_diagram Not quite as complicated as to require a book, [Hammond] I knew you'd love it. All you really need is Chapter 2. Look at Figure 19 on page 54 however... can you believe how SIMPLY and dramatically this diagram explains the Lorentz Contraction....wow... the whole of SR in a single picture! And check out the Twins Paradox diagram on page 44... However, George is right: This kind of space-time diagram does abolish the need for the "magic factor". [Hammond] Right... no 'scale factors' needed... all lengths in the diagram appear as "true lengths". I checked it trigonometrically and it's identical to the Lorentz transformation without using a factor. There's no distortion. I'm very pleased with this kind of diagram, I've already used it to confirm the formulas for length-contraction and time-dilation. Thanks! [Hammoond] Yeah.... I really never could visualize SR until I came across this book and discovered the "oblique axis" method.... and discovered that the 'experts' use it all the time! Best Wishes, Ram Rachum. |
