Superstrings

The quest to find the ultimate building blocks of nature is one of the oldest in all of physics.  While we are far from knowing the answer to that question, one intriguing proposed answer is that all matter is composed of tiny “strings.”  The known particles are simply different vibrational patterns of these strings.  In this video, Fermilab’s Dr. Don Lincoln explains this idea, using interesting and accessible examples of real-world vibrations.
