- S1 E4 - From the Ground Up: How Flying WorksNovember 22, 202328minGet a whirlwind introduction to the scientific truths about how planes fly through the air. This episode overturns the (often-very-wrong) way flight is taught in introductory physics classes and focuses on two relevant subjects involved in flight: air circulation and how the wing pushes air downward.Free trial of The Great Courses Signature Collection or buy
- S1 E5 - From the Sky Down: How Falling WorksNovember 22, 202327minIntroductory physics classes tell you that a ball thrown on the surface of the earth follows a parabola. What happens when you take away the simplifying assumptions in this scenario? How do we factor in air resistance and the Earth’s rotation? What happens when an object falls from very great heights?Free trial of The Great Courses Signature Collection or buy
- S1 E6 - Myths of Orbital MotionNovember 22, 202332minIn this episode, revisit some of the common misconceptions we have about how the universe works, with a focus on our solar system. Two myths you’ll bust: that the orbits of planets are all fixed ellipses and that astronauts on the International Space Station live in zero gravity.Free trial of The Great Courses Signature Collection or buy
- S1 E7 - What’s Inside Atoms?November 22, 202329minDiscover a very different idea about the real essence of matter as it relates to the molecules and atoms of chemistry. Learn to think about matter as entirely empty space, not tiny balls; consider the inside of a proton and neutron; and ponder the question of where, exactly, mass comes from.Free trial of The Great Courses Signature Collection or buy
- S1 E8 - The Truth Is In Here: The Science of AliensNovember 22, 202330minThere are some popular misconceptions about alien life that science fiction writers have said often enough that we take them to be likely or true. But are they? Professor Lincoln unpacks the possibility of silicon-based life and truths about the Drake equation, which posits the number of possible civilizations in our universe.Free trial of The Great Courses Signature Collection or buy
- S1 E9 - Misconceptions about EvolutionNovember 22, 202331minIt’s often the misconceptions about evolution that lead people to not believe in it. This episode tackles four prevalent myths about the theory of evolution: that it explains how life began, that it states humans descended from chimpanzees, that evolution has a goal, and that evolution means more complex organisms will evolve.Free trial of The Great Courses Signature Collection or buy
- S1 E10 - Nutrition’s All About You—and Your Gut BiomeNovember 22, 202332minHow do misconceptions about nutrition spread? What if what you learned about digestion isn’t the entire story? In this episode, examine the unseemly alliance between science, advertisers, and the media; and make sense of the important role that a fascinating microbe ecosystem plays in how the human gut works.Free trial of The Great Courses Signature Collection or buy
- S1 E11 - Humans Are Not Peas: Myths about GeneticsNovember 22, 202332minIt might surprise you to know that most human characteristics (including eye color) aren’t governed by a single gene. Nor do dominant genes always become more common over time. As you’ll discover, we owe these and other misconceptions about genetics to the Punnett squares you first encountered in high school biology.Free trial of The Great Courses Signature Collection or buy
- S1 E12 - Getting Smarter about IntelligenceNovember 22, 202332minFocus your attention on popular myths about the human brain. There’s the myth that we only use 10 percent of our brain power, the concept that people can be right- or left-brained, and the complexities of learning styles and IQ scores to consider. Use current science to make sense of how your brain works.Free trial of The Great Courses Signature Collection or buy
- S1 E13 - Exposing the Truth about RadiationNovember 22, 202334minRadiation is one of the most misunderstood of all scientific phenomena. Get the scientific truths about this subject by investigating the four types of ionizing radiation, including alpha radiation, beta radiation, gamma radiation, and neutron radiation. Then consider how much radiation you encounter every day, and how much of it you can ignore.Free trial of The Great Courses Signature Collection or buy
- S1 E14 - How Does Carbon-14 Dating Work?November 22, 202330minClarify oversimplified ideas concerning how carbon dating works and get a stronger appreciation of just how complicated and sophisticated a scientific technique it is. While dating objects under 60,000 years old has become relatively easy, the current accuracy of modern science depends on taking subtle effects into consideration. You’ll learn why doing it precisely takes some care.Free trial of The Great Courses Signature Collection or buy
- S1 E15 - How Statistics Can Lie to YouNovember 22, 202330minConsider the best way to read statistics correctly: by understanding the various ways they can be misused to fool you. Here, Professor Lincoln discusses how averages and percentages can make certain statistics seem shocking, reveals how you should rethink the confidence threshold of 95 percent that scientists use, and more.Free trial of The Great Courses Signature Collection or buy
- S1 E16 - Does Thermodynamics Disprove Evolution?November 22, 202329minTake on a few of the simpler misunderstandings revolving around heat as it relates to thermodynamics: the ways heat energy moves and changes. Is it correct to say heat always rises? Are entropy and disorder synonymous? How do we often misinterpret the second law of thermodynamics, and what does it tell us about evolution?Free trial of The Great Courses Signature Collection or buy
- S1 E17 - How Relativity Is MisunderstoodNovember 22, 202333minAt its core, relativity is about something very simple: how two people in relative motion see the world differently. In the first of two episodes on misunderstandings about relativity, explore the Lorentz transforms, then journey through a seeming paradox that disappears once you use the Lorentz transforms properly.Free trial of The Great Courses Signature Collection or buy
