Isaac Newton built on many of Galileo's insights when developing his laws of motion. These ideas would later play a critical role in Einstein's thinking about energy, mass, light, and motion.

In 1915, Einstein published his paper on general relativity, a theory of gravitation. While Newton’s gravity explained ...

Although the study of time became scientific during the time of Galileo and Newton, a comprehensive explanation was given only in this century by Einstein, who declared, in effect, time is simply ...

Newton concluded the Earth’s movement was due to the force of gravity. But Einstein’s theory states that there is no force of gravity, it’s just the effect of our planet as it freely falls ...

From Isaac Newton’s ground-breaking work on matter and motion, to Albert Einstein’s revolutionary ideas about energy and space-time, and finally to David Bohm’s hypothesis linking quantum ...
