In 1915, in his General Theory of Relativity, Einstein basically said that the combined speed of an object's motion through space and time is always exactly equal to the speed of light. In other words, as you travel faster, time "slows down" for you. At the speed of light, time stops. In 1971, Haefele and Keating flew caesium beam atomic clocks around the world on a commercial jet. When they compared the clocks to identical stationary clocks on the ground, they found that less time had elapsed on the flying clocks - precisely in accordance with Einstein's discoveries from 56 years earlier! Yes, it took that long, and there was a hell of a lot of testing in - between. There's an important analogy here: In software development, as in quantum physics, theories are wonderful and can be very exciting, but it is only through the rigors of testing that we can determine the facts and capabilities of our product. How much testing have you done on your latest creation? Whe...
