From Newton to Einstein: Changing Conceptions of the Universe

This concise narrative follows the evolution of our understanding of space, time and gravity, beginning with Sir Isaac Newton’s universal law of gravitation. The opening chapters explain how a simple inverse‑square formula unified the motions of fallen fruit, orbiting planets and, later, even atomic particles. By setting the stage with the scientific climate of the 1600s, the book shows how Newton’s ideas became the bedrock for later breakthroughs.

The story then moves to the early twentieth century, where puzzling experimental results forced physicists to reconsider absolute time. Introducing the work of Michelson, Lorentz and others, the narrative leads to Albert Einstein’s bold re‑imagining of spacetime and the birth of relativity. Supplementary photographs of the key scientists and a brief appendix offer extra depth, making the material accessible yet rewarding for anyone curious about how these revolutionary ideas reshaped our view of the universe.
