Rational Thinker is a podcast dedicated to exploring the rich and often surprising history of science — the discoveries, the debates, and the remarkable individuals whose curiosity and perseverance transformed our understanding of the world. From the revolutionary insights of the Scientific Revolution to the groundbreaking breakthroughs of the modern era, each episode examines the human stories behind the ideas that shaped civilization. I invite my listeners to look beyond the textbook and engage with science not merely as a collection of facts, but as an evolving, deeply human pursuit of truth. Whether you are a lifelong student of history, a science enthusiast, or simply someone who wonders how we came to know what we know, this podcast offers thoughtful, well-researched narratives that illuminate the minds and moments that moved science forward.

Helium is a very common element in our universe. However, due to its characteristics, it's very rarely found on Earth. This video shows how scientists in the 19th century overcame this obstacle, over the course of decade
Show notesFor over two centuries, Newton’s law of gravity accurately predicted the motions of all the planets in the solar system. But that all changed in 1859, when French astronomer Urbain Le Verrier discovered a strange anomaly
Show notesIn 1895, German physicist Wilhelm Conrad Röntgen discovered a new type of radiation. It was invisible and penetrating to some materials, but not others. He called the radiation "X-rays," and the phenomenon took over the
Show notesThe gravitational constant, or at least what it represents, is a fundamental part of our universe. It represents the strength of gravity and, to our knowledge, remains unchanged throughout space and time. But how did our
Show notesIn 1887, physicists Albert Michelson and Edward Morley discovered a new phenomenon that would come to be known as the fine structure of spectral lines. These spectral lines split into two or more components, and other ef
Show notesAbsolute zero is the theoretical limit to how cold temperature can reach. The quest to calculate the value of it started in the 1700s, but wasn't accurately done so until the mid 1800s by British physicist William Thomso
Show notesThe weights of atoms and molecules are quite precise today, but has quite a long and complicated history. This video dives into the very beginning of that history, right when modern atomic theory was beginning to surface
Show notesIn the late 19th century, cathode rays were the dominant topic of discussion in the world of physics. Scientists all over the globe were debating over what the nature of those rays were and what that implied for our real
Show notesIn 600 BC, Greek philosopher Thales of Miletus noticed that the gemstone amber attracted light objects when it was rubbed against a cloth. Unbeknownst to him, he had discovered the phenomenon of static electricity. But h
Show notesIn the 1770s, a revolution in chemistry had just begun, starting in Uppsala, Sweden. A young apothecary named Carl Wilhelm Scheele began a series of experiments that led to the eventual downfall of an entire theory of fi
Show notesTechnetium is quite an interesting element and has just as interesting of a history. Many had tried to discover it and failed, and this is because of how unstable all of its isotopes are. The only way to discover the ele
Show notesEver since the discovery of the proton in 1919 by Ernest Rutherford, scientists had been on a mission to break atoms apart, splitting them into their smaller components in hopes of changing elements into others. This was
Show notesHenry Moseley was a British physicist known for his discovery of Moseley's Law, which relates the atomic number to the "characteristic X-ray" of each element. Before Moseley's discovery, the atomic number was merely an a
Show notesAfter the discovery of beta radiation by Ernest Rutherford in 1898 and the formulation of the mass-equivalency relation by Einstein in 1905, scientists realized that beta radiation was behaving in an odd way. The expecte
Show notesThe 1920s were an era of intense discovery and progress in the world of physics. Concepts such as matrix mechanics, the Schrödinger model of the atom, the Heisenberg uncertainty principle, and more dominated this era of
Show notesIn the 1780s, an Italian physicist named Luigi Galvani made a shocking discovering when experimenting with the remains of frogs. He found that when he touched a the nerves of a frog with a lancet, and at the same time, d
Show notesThe first liquefaction of helium in 1908 by Dutch experimental physicist Heike Kamerlingh Onnes was revolutionary. For the first time, scientists could push the boundaries of extremely low temperatures and see what happe
