2.13 Conclusion The theoretical discovery of the Lorentz transformation was an important s the learning process leading to Special Relativity, but its deep meaning was understood before Einstein. In our presentation we have made it clear that the Lorentz transformation can be derived from the two postulates of Special Relativity, which are physically more transparent than what, at first sight, appears "only" as a mathematical transformation. From the physical point of view it is more...

Exercise 3. (12p) (Lorentz boosts) The Maxwell equations (7) are invariant under Lorentz transformations. This implies that given a solution of the Maxwell equa- tions, we obtain another solution by performing a Lorentz transformation to the solution. A particular Lorentz transformation is a Lorentz boost with velocity v in - direction and acts on the electric and magnetic field strength as given in appendix B. (1) Tong) Now consider the electric and magnetic field due to a line along the...

3. Consider a linear model with only categorical predictors, written in matrix form as y = Xißi +6, Now suppose we add some continuous predictors, resulting in an expanded model y X + ε. Now consider a quantity tTß, where t-M 切is partitioned according to the categorical and continuous predictors. Show that if t s stimable in the first model, then tB is estimable in the second model. If you write X [X1|X2], you may assume that r(X) (X (X2)....
