The Science of Everything Podcast

A journey through the history of Earth's changing climate, in which we explore how Earth's climate has fluctuated over the past billion years. After reviewing the various temperature proxies used to estimate past climactic conditions, we discuss the varying hothouse and icehouse periods of Earth's history, the onset of the Quarternay Ice Age, the current interglacial period, the anomoly of the Younger Dryas, the Medieval Warm Period and Little Ice Ages, and the rapid rise in temperatures during the twentieth century. Recommended pre-listening is Episode 90: Climate Systems.

In this special collaboration with I Know Dino podcast, we discuss the history and impact of dinosaurs in popular culture and media. We cover the history of the scientific study of dinosaurs and how their presentation in media has changed over time with new discoveries, and what aspects of their behaviour and appearance tend to be presented accuracy or inaccurately. We also discuss lesser-known aspects of understanding dinosaurs, such as how changes in the atmosphere and ecosystem would affect dinosaurs of they were to be alive today.

A journey through the digestive system, beginning with the mouth and progressing through the esophagus, stomach, small intestine, and large intestine, we consider the structure and function of all key components of the gastrointestinal tract and their roles in facilitating the metabolism of our food. We also discuss the contribution of accessory organs, including the liver, gall bladder, and pancreas. We conclude by considering a few myths about digestion.

An introduction to the conceptual and mathematical framework of Einstein's General Theory of Relativity. We begin by considering the key insight of gravity as a geometric phenomenon, and how the curvature of spacetime by matter explains the equality of inertial and gravitational mass. We then discuss the mathematics of general relativity, including geodesics, differential manifolds, covariant derivatives, the metric tensor, Christoffel symbols, the Riemann curvature tensor, the Ricci tensor, and the energy-momentum tensor. The episode concludes with a derivation and explanation of the significance of Einstein's Field Equations. Recommended pre-listening is Episodes 114 and 115: Special Relativity 1 and 2.  If you enjoyed the podcast please consider supporting the show by making a PayPal donation or becoming a Patreon supporter. https://www.patreon.com/jamesfodor https://www.paypal.me/ScienceofEverything  

An introduction to the scientific study of emotion, including a discussion of the difficulties in defining emotions, discrete and dimensional methods of classifying emotions, the functional and representational roles of emotions, and an overview of major psychological theories of emotion, including the James-Lange and Cannon-Bard theories. We also examine the neurobiological basis of emotion, including the roles of the orbitofrontal cortex, the ventromedial prefrontal cortex, the cingulate cortex, and the amygdala.

An introduction to hormones and the endocrine system, including a discussion of the definition of hormones and their production, storage, release, and mechanisms of action. I also consider the mechanisms of control and regulation of hormone production, focusing on the role of the hippocampus and the pituitary gland. I conclude with an overview of major endocrine glands in the human body, including the gonads, adrenal glands, thyroid gland, and the thymus.

Dive into the fascinating mechanics of human motor control, exploring how the spinal cord and various brain regions like the cerebellum and basal ganglia orchestrate movement. Discover the complex interplay between different areas in the brain, including the roles of inhibition and action selection in decision-making. The discussion emphasizes the intricate communication between top-down and bottom-up feedback in executing motor tasks, alongside insights into potential disorders like Huntington's disease. It's a captivating look at how our bodies move!

In this special episode I discuss various topics in evolution and genetics with Art Woods of the Big Biology Podcast. We begin by analysing various ideas associated with the extended evolutionary synthesis, including plasticity, epigentics, and niche construction, discussing the extent to which these ideas are a challenge or merely an addition to the mainstream understanding of evolution. We then consider several common misconceptions about genetics, including the idea of DNA as a blueprint and genetic essentialism. We conclude with a discussion of some politically contentious aspects of genetics.   If you enjoyed the podcast please consider supporting the show by making a PayPal donation or becoming a Patreon supporter. https://www.patreon.com/jamesfodor https://www.paypal.me/ScienceofEverything
