The invaluable legacy: In 1905, the ideas of an employee of the Swiss Patent Office changed the world forever. His legacy lives on in the modern generation of physicists striving to create a theory of everything.

A century of Einstein: Scientific American has presented Einstein's theories - along with their improvements and the reactions they provoked - since scientists began to realize the significance of his groundbreaking publications in 1905. A sample of our news reports is provided, some expressed by leading physicists of the time.

Powers of the universe unite!: In an article in Scientific American in 1950, Einstein outlined his long-awaited unified theory. Too bad it was mistaken.

Einstein in our daily lives: Are you navigating through a dense forest with a GPS device in hand? Hanging a picture on the wall using a laser level? Making photocopies? For all these, you owe thanks to Einstein.

Emerging atomic technologies: A new generation of technological innovations aims for the practical application of Einstein's theories in computers, hospitals, and even submarines.

Einstein's compass: How did the magnetic properties of a small iron bar distract Einstein from his effort to perfect the famous general theory of relativity?

Was Einstein right?: Unlike almost all of his contemporaries, Einstein believed that quantum mechanics would yield to a classical theory. Nowadays, some researchers tend to agree with him.

Violations of relativity: In their quest to uncover evidence capable of leading them to a Final Theory, scientists are seeking phenomena that contradict Einstein's principle, the questioning of which was once considered sacrilegious.

A cosmic puzzle: A new version of Einstein's cosmological constant may point the way to transcend general relativity.

Einstein and Newton: The two giants of science were similar in intellect and temperament.
