Edwin Hall: A Short Biography

Edwin Herbert Hall was an American physicist known for his discovery of the Hall effect, which has had significant implications in the field of solid-state physics and electronics. Edwin Hall was born on November 7, 1855, in Great Falls, New Hampshire, USA. He attended Phillips Exeter Academy and later enrolled at Harvard University, where he pursued a bachelor's degree in physics. Hall passed away on November 20, 1938. He was recognized for his contributions to physics, and received many honors and awards.

In 1879, while still an undergraduate student at Harvard, Hall made a groundbreaking discovery that would later be known as the Hall effect. He was conducting experiments to better understand the behavior of electrical currents in the presence of magnetic fields when he observed that a voltage developed perpendicular to both the direction of current flow and the applied magnetic field. This phenomenon came to be known as the Hall effect, and Hall published his findings in a paper titled "On a New Action of the Magnet on Electric Currents."

After completing his undergraduate studies, Hall pursued further education and earned his Ph.D. from Harvard University in 1880. He then embarked on an academic career, teaching and conducting research. He held positions at several institutions, including Harvard University, where he was an assistant professor of physics.

 Edwin Hall's discovery of the Hall effect had significant implications for the field of solid-state physics. The Hall effect is a crucial tool for studying the electrical properties of materials and has numerous practical applications. Hall's work laid the foundation for future research in semiconductor physics and the development of modern electronic devices.

AI Technical Trustability Update

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.
