Hans Christian Ørsted (1777-1851) was a Danish physicist and chemist who made significant contributions to the understanding of electromagnetism. He is most famous for discovering the relationship between electricity and magnetism, which is now known as Ørsted's law. Ørsted was born in Rudkøbing, Denmark, and received his education at the University of Copenhagen, where he later became a professor of physics. Throughout his life, he conducted experiments and research on a variety of scientific topics, including electricity, magnetism, and chemical reactions.

In 1820, Ørsted made a groundbreaking discovery that would change the course of physics forever. While conducting a series of experiments with electricity and magnetism, he noticed that an electric current flowing through a wire caused a nearby compass needle to deflect. This was the first experimental evidence of a relationship between electricity and magnetism, and it provided the foundation for the development of electromagnetism as a branch of physics. Ørsted's discovery was a crucial step in the development of electromagnetism, and it paved the way for future scientists such as Michael Faraday and James Clerk Maxwell to build upon his work and develop a more complete understanding of the behavior of electric and magnetic fields.

In addition to his scientific contributions, Ørsted was also a deeply philosophical and humanitarian individual who believed in the importance of using science for the betterment of humanity. He was a strong advocate for education and scientific literacy, and he worked to promote these ideals throughout his life. Hans Christian Ørsted's legacy lives on through his scientific discoveries and his commitment to using science to improve the world. Today, he is remembered as one of the founding fathers of electromagnetism and a pioneer of modern physics.

While working on an update to my RF Cafe Espresso Engineering Workbook project to add a couple calculators about FM sidebands (available soon). The good news is that AI provided excellent VBA code to generate a set of Bessel function plots. The bad news is when I asked for a table showing at which modulation indices sidebands 0 (carrier) through 5 vanish, none of the agents got it right. Some were really bad. The AI agents typically explain their reason and method correctly, then go on to produces bad results. Even after pointing out errors, subsequent results are still wrong. I do a lot of AI work and see this often, even with subscribing to professional versions. I ultimately generated the table myself. There is going to be a lot of inaccurate information out there based on unverified AI queries, so beware.
