The NOVA season 31 episode 3 titled "The Elegant Universe: Part 1" explores the concept of string theory, which is considered to be the elegant theory that unifies the four fundamental forces of the universe - gravity, electromagnetism, strong and weak nuclear forces. The episode takes us on a journey through the history of physics and how the discovery of particle physics paved the way to string theory.

The episode is divided into different sections, each highlighting a particular point in the evolution of the string theory. The first section introduces viewers to the 17th-century physicist Isaac Newton, whose laws of motion and gravity explained the way objects move in the universe. The episode goes on to explore how the laws of electromagnetism were discovered, and how they were combined with Newton's laws to form the foundation of classical physics.

The show then delves into the 20th century, where the discovery of the atom and the discovery of the fundamental forces that govern it began to disrupt classical physics. This disruption ultimately led to the theory of relativity, which Einstein introduced in 1905. The theory of relativity made major contributions to the understanding of gravity, but it was not able to incorporate the fundamental forces governing the atom.

The episode then introduces us to quantum mechanics, a field of physics that describes the behavior of subatomic particles such as electrons and photons. Quantum mechanics revolutionized classical physics by introducing probability and uncertainty. The show explains that strings could solve the problem of unifying relativity and quantum mechanics.

The final section of the episode focuses on the underlying idea of string theory. The show explains how string theory proposes that the universe is made up of tiny strings that vibrate at different frequencies and generate the particles that make up the universe. This theory also proposes that there may be extra dimensions of space hidden from our perception that need to be taken into account.

Overall, "The Elegant Universe: Part 1" is an informative episode that introduces casual viewers to the complex world of string theory. The show effectively uses detailed explanations, historical anecdotes, and interviews with expert physicists to help viewers understand the importance and validity of string theory. Theoretical concepts and mathematical equations are also explained in a clear and concise way that will not intimidate viewers without a scientific background.
