Podcasts about conic sections

Conic sections – the curves made by slicing through cones at various angles – were studied by the ancient Greeks, but because of their useful properties, have many real-world uses. Planets have elliptical orbits, projectiles move in parabolas, and cooling towers have hyperbolic cross-sections. But did you know that one of the most important curves in economics is a hyperbola? Or that ellipses are used to cure kidney stones?A lecture by Sarah HartThe transcript and downloadable versions of the lecture are available from the Gresham College website:https://www.gresham.ac.uk/watch-now/conic-sectionsGresham College has been giving free public lectures since 1597. This tradition continues today with all of our five or so public lectures a week being made available for free download from our website. There are currently over 2,000 lectures free to access or download from the website.Website: http://www.gresham.ac.ukTwitter: http://twitter.com/GreshamCollegeFacebook: https://www.facebook.com/greshamcollegeInstagram: http://www.instagram.com/greshamcollege

In the Gaming Hut we look at GMing techniques to respond to that moment when one player makes a unilateral choice that causes the rest of the group to groan in protest. The History Hut acquires a pointy hat as beloved Patreon backer Bob J. Koester asks us to delve into Yale's 1825 Conic Sections […]

The perfect elliptical geometry of the Carolina Bays is a clue about the mechanism by which the bays were formed. A trail of evidence points toward an extraterrestrial impact that caused a mass extinction during the ice age.

In this podcast, you will learn the different types of conic sections

We are joined by Chris Cottrell, the man behind the Dabbler's Den, to talk about his ongoing research into the Carolina Bays, the Younger Dryas, and the possibility of a large oblique impact into Saginaw Bay in the Great Lakes region.Chris gives us the rundown of the work of Antonio Zamorra and others who have done work on the Carolina bays and what they think may have caused this enormous field of geomorphic features in the landscape of the eastern seaboard of the United States. He also gives a great(and terrifying) minute-by-minute description of the catastrophic event that resulted in the Bays, and what it would have looked like from the ground.Enjoy!CLICK TO PLAY Brothers of the Serpent Episode 107 Carolina Bays from Google EarthLIDAR of Carolina BaysMore LIDAR - Note the farmland fields for scaleLIDAR of Carolina Bays and drainage systemsBay ellipses are "Conic Sections"Convergent long axes of Carolina Bays - Yellow is uncorrected, green is corrected for sphere and rotationConvergent long axes shown on spherical mapCore sample info taken from Howard BayBay features slowly being erased by farming, etc

We have a very special episode for all you snake sibs out there, we interviewed Mr. George Howard, who has been involved with the Comet Research Group from the very beginning in the work on the Younger Dryas Impact Hypothesis, which we have spoken of many times in previous episodes. George gives us all kinds of insider insights on the evolution of the hypothesis over the years, leading up to and including the recent publications on the Hiawatha Crater in Greenland, and where he sees the research going in the future and how this new data might affect the "standard model" of human development.George also sets the record straight on the attempted character assassination of Dr. Allen West, discusses the Carolina Bays, the Alaska Muck, and at least once refers to skerptards as "skerptards". Follow George on Twitter @CosmicTuskand at his website and blog, The Cosmic Tusk. Enjoy!

We solve simultaneously the equations of a plane and a cone and show that the intersections are circles, parabolas, ellipses, hyperbolas, straight lines or just the origin.
