Scientists Develop Atomic-Scale Memory

Summary:
In 1959, physics icon Richard Feynman, in a characteristic back-of-the-envelope calculation, predicted that all the words written in the history of the world could be contained in a cube of material one two-hundredths of an inch wide - provided those words were written with atoms. Now, a little more than 40 years after Feynman's prescient estimate, scientists at the University of Wisconsin-Madison have created an atomic-scale memory using atoms of silicon in place of the 1s and 0s that computers use to store data.
