In the field of theoretical physics, the discovery of superconductivity by Kamerlingh Onnes was a groundbreaking event. However, it took almost half a century for Bardeen, Cooper and Schrieffer to provide a theoretical explanation for this phenomenon. During this time, many of the brightest minds in physics attempted to develop a microscopic understanding of superconductivity but failed. In his paper "Failed Theories of Superconductivity," Joerg Schmalian provides a summary of some of these unsuccessful attempts. Despite their lack of success, these theories were not without merit. They served as stepping stones towards the eventual formulation of the BCS theory, which is now widely accepted as the most accurate explanation for superconductivity. Furthermore, these failed theories illustrate that mistakes are an inevitable and healthy part of scientific discourse. Even incorrect or inapplicable theories can inspire new ideas and lead to breakthroughs. Schmalian's paper highlights several key examples of failed theories, including those proposed by Fritz London and Lev Landau. London's theory suggested that electrons in a superconductor formed pairs due to attractive forces between them. While this idea was ultimately proven incorrect, it did inspire later work on electron pairing in superconductors. Similarly, Landau's theory proposed that superconductivity was caused by electrons forming a Bose-Einstein condensate. While this theory also turned out to be inaccurate, it helped pave the way for later research on Bose-Einstein condensates. Overall, Schmalian's paper emphasizes that failure is an essential component of scientific progress; without attempting and failing at various approaches to understanding phenomena like superconductivity we would not have arrived at our current level of knowledge and understanding. As such, we should embrace failure as an opportunity for growth and discovery rather than viewing it as something negative or discouraging.

Superconductivity is a special property of some materials that allows electricity to flow through them without any resistance. Scientists discovered it a long time ago but it took them many years to understand how it works. Some scientists tried to explain superconductivity in different ways, but their ideas didn't work. However, these failed theories helped other scientists come up with a better explanation called the BCS theory. Sometimes, when we try something and fail, it can help us learn and come up with new ideas that lead to success later on. Two scientists named Fritz London and Lev Landau had their own ideas about how superconductivity worked, which also helped other scientists learn more about it."
Definitions- Superconductivity: A property of certain materials that allows electricity to flow through them without any resistance.
- Resistance: The force that slows down or stops the flow of electricity through a material.
- Microscopic understanding: Understanding something at a very small scale, like looking at individual atoms or molecules.
- Attractive forces: Forces between particles (like electrons) that pull them towards each other.
- Bose-Einstein condensate: A state of matter where particles (like atoms) are packed together so tightly they start acting like one big particle.
Failed Theories of Superconductivity: An Overview
Superconductivity is a phenomenon that has been studied by physicists for over a century. In 1911, Dutch physicist Kamerlingh Onnes discovered superconductivity and since then, many of the brightest minds in physics have attempted to develop a microscopic understanding of this phenomenon. However, it wasn't until 1957 that Bardeen, Cooper and Schrieffer were able to provide an accurate explanation for superconductivity with their BCS theory.
In his paper "Failed Theories of Superconductivity," Joerg Schmalian provides an overview of some of the unsuccessful attempts at explaining superconductivity prior to the formulation of the BCS theory. Despite their lack of success, these theories were not without merit; they served as stepping stones towards the eventual formulation of the BCS theory and illustrate that mistakes are an inevitable part of scientific discourse. This article will provide a summary and analysis of Schmalian's paper in order to better understand how failure can be used as an opportunity for growth and discovery rather than something negative or discouraging.
Theory Proposed by Fritz London
One such failed attempt was proposed by Fritz London in 1935. His theory suggested that electrons in a superconductor formed pairs due to attractive forces between them. While this idea was ultimately proven incorrect, it did inspire later work on electron pairing in superconductors which eventually led to the development of the BCS theory.
Theory Proposed by Lev Landau
Another failed attempt was proposed by Lev Landau in 1950 who suggested that superconductivity was caused by electrons forming a Bose-Einstein condensate (BEC). While this theory also turned out to be inaccurate, it helped pave the way for later research on Bose-Einstein condensates which eventually led to new insights into quantum mechanics and other related fields such as condensed matter physics.
Conclusion
Overall, Schmalian's paper emphasizes that failure is an essential component of scientific progress; without attempting and failing at various approaches we would not have arrived at our current level knowledge and understanding regarding phenomena like superconductivity . As such, we should embrace failure as an opportunity for growth rather than viewing it as something negative or discouraging.
