Albert Einstein
The history and future of physics changed about 80 years ago, when a young Swiss patent clerk named Albert Einstein quietly but firmly showed a multitude of chagrined and chastened physicists the direction they would have to take in order to achieve the necessary modification of the great natural laws of physics, which had somehow to be accomplished.
The single hypothesis Einstein proposed was simple. To wit, "Let us take the basic assumption that the measured speed of light (or of any electromagnetic wave) will always be the same anywhere in the Universe, no matter what the motion of the observer who is making the measurement, and no matter what the motion of the light source."
Albert Einstein charted a course through a no-man's land, and then proceeded to follow it to the bitter end. But what were the implications and conclusions that had to be drawn if physicists were to accept Einsteins very practical viewpoint and his basic postulate that the velocity of light remained constant under all circumstances' Among other things like the theory that showed that, no matter how much energy one gave to a particle, one could not accelerate it to a speed greater than the
