The Rutherford Experiment and Hit the Penny
... With the growing evidence that the atom is made of even smaller particles, in the early 1900s J. J. Thomson reasoned that because electrons comprise only a very small fraction of the mass of an atom (they are very small), they probably made up an equally small fraction of the atom's size. He propose ...

Daniel Heineman Prize: The Quest for Quantum Gravity
... • Many attempts give up Lorentz invariance at the start, and it has even been argued that this is a necessary feature of quantum gravity. • It is hard to see how the successes of Special Relativity can then be maintained. E.g., the Standard Model would have ~20 extra parameters (different speeds of ...
