HIs equations explain just about everything in modern engineering, not just calculating orbits and yields in nuclear reactions where matter is changed to energy, but how that mysterious power source works that makes your computer go, such that you can type these nonsense posts of yours and worship the DS from a safe distance.His equation was good enough to build a bomb that destroys. That's about it.
Your buddy High Spy can have a sit-down with you one day and explain it better than I can, as an EE major. Suffice it to say, the special relativity examples of objects moving -- trains, skateboards, flashlights, jump ropes, measuring rods, and clocks -- is the less abstract way to learn about it. Special relativity actually comes from problems that arose in the study of electricity and magnetism and trying to account for how electricity and magnetism are observed across inertial frames. And what makes it so much worse for the DS, is that relativity was just one of Einstein's many contributions. He had throw-way stuff like Brownian motion that for anyone else, would have been a discovery worthy of making them at least a science demi-god.
