These podcasts discuss topics related to science. Some of the podcasts analyze examples of bad science or deal with new discoveries that are still not accepted by mainstream science.
This presentation looks at ways of identifying fake news and describes the critical thinking skills of independent thinkers. Global warming is used as an example.
The Carolina Bays do not get the attention that they deserve in geology books. Putting lipstick on the Carolina Bays is not a bad idea for calling attention to these geological features that have been neglected and dismissed as unimportant for a very long time.
The hypothesis that the Carolina Bays were created by the saturation bombardment of pieces of ice ejected by an extraterrestrial impact on a glacier during the Ice Age and the possibility that several impacts could have triggered the Younger Dryas cooling event.
The elliptical geometry implies that the bays originated as inclined conical cavities, but the dates indicate that the bays could not have formed at the same time and that they formed by gradualistic processes over thousands of years.
Viscous relaxation is a plastic deformation process driven by gravity that tends to smooth out geological features by making hills less prominent and valleys less deep.
Structural geology measures the geometry of present-day geological formations to determine the history of deformation and understand the stress field that resulted in the observed characteristics.
This presentation discusses the 31-kilometer impact crater beneath Hiawatha Glacier in northwest Greenland that may have formed at the onset of the Younger Dryas cooling event.
A book published in 2006 proposed that a cosmic chain of events culminated in the extinction of the megafauna approximately 13,000 years ago. This book established what was later called the Younger Dryas Impact Hypothesis.
Discussion of the flooding associated with the meteorite impact 12,900 years ago. The story is complicated because there were several meltwater pulses at the end of the Ice Age.
