PBS Space Time Season 2016 Episode 42 Quantum Vortices and Superconductivity + Challenge Answers

PBS Space Time season 2016 episode 42 entitled "Quantum Vortices and Superconductivity + Challenge Answers" delves into the fascinating world of quantum mechanics and superconductivity. The episode begins with the hosts discussing the previous episode's challenge, which involved a firework rocket launching from a moving car. The hosts provide the solution to the challenge and explain the physics behind it.

The episode then dives into the world of quantum mechanics, where the laws of physics differ from those of classical mechanics. The hosts explain how superconductivity, which is the complete absence of electrical resistance, occurs at extremely low temperatures. They also describe how magnetic fields can penetrate through superconductors in the form of tiny tornadoes, known as quantum vortices.

The hosts explore the science behind how these quantum vortices affect the superconductivity of materials and describe how this phenomenon is being studied in laboratories all over the world. They also explain how quantum vortices can be used in the development of superconducting electronics, such as MRI machines and particle accelerators.

The episode then discusses how scientists are trying to understand the fundamental laws of physics by studying the behavior of electrons in superconducting materials. They describe how the behavior of electrons in a superconductor is similar to the behavior of waves in a fluid, and how this can lead to the creation of exotic particles known as Majorana fermions.

Towards the end of the episode, the hosts revisit the challenge from the previous episode and provide a more advanced challenge for viewers to solve. They leave viewers with a reminder that science is all about curiosity and the constant pursuit of knowledge.

Overall, "Quantum Vortices and Superconductivity + Challenge Answers" is an engaging and informative episode that delves into the mysterious and fascinating world of quantum mechanics and superconductivity. The hosts do an excellent job of breaking down complex concepts into easily understandable terms, making this episode accessible to viewers with varying levels of scientific knowledge.
