Episode 6: Thermodynamics

A survey of extinct animal species from the Permian through the Cretaceous periods. We discuss important differences between anapsids, synapsids, and diapsids, and then review diverse species from all groups, including pelycosaurs, therapsids, parareptiles, euryapsids, pterosaurs ...  Show more

A journey through the evolutionary history of animals, beginning with the split of the metazoans from protists about 760 million years ago and ending with the rise of the amniotes about 340 million years ago. The focus is the development of key morphological traits necessary for ...  Show more

Melvyn Bragg and guests discuss the Second Law of Thermodynamics which can be very simply stated like this: "Energy spontaneously tends to flow from being concentrated in one place to becoming diffused and spread out". It was first formulated – derived from ideas first put forwar ...  Show more

Thermodynamics is fundamental to mastering chemistry concepts and understanding the energy dynamics within biological systems crucial for the MCAT. In this episode, host Sam Smith dives into the laws of thermodynamics, covering everything from the zeroth law to the third. You'll ...  Show more
