Does the Inertia of a Body Depend Upon its Energy Content?

This is the fourth of four scientific papers published by Albert Einstein in his miracle year of 1905. In this paper, Einstein introduced the famous equation E=mc², showing that mass and energy are two forms of the same thing.

Summary

Einstein’s idea meant that mass is not just a measure of how much matter an object contains, but also a form of stored energy. His equation, E=mc², shows that E (energy) is equal to m (mass) multiplied by c² (the speed of light squared). Because the speed of light is such a large number, even a small amount of mass can be converted into an enormous amount of energy. This concept explains how stars shine and why nuclear reactions release so much power. Einstein’s equation revealed a deep connection between matter and energy, transforming our understanding of the physical world.

Einstein’s paper on the relationship between mass and energy helped change the course of modern physics. It laid the theoretical foundation for understanding nuclear energy, from the power of the sun to the development of atomic technology. His simple yet profound equation became one of the most famous and important in science, shaping how we think about matter, energy, and the forces of nature.
