Since then, he's been completely obsessed with me, refusing to admit that he's a complete buffoon who fell for the dumbest hoax in human history, but instead doubling down on everything and venting about what a stupid shill I am to whomever will listen. So let's react to him doing that!Humiliating Lord Jamar in live debate: https://www.youtube.com/watch?v=guWSyD5d8tAWatch my other flat earth debunks: http://bit.ly/ProfDaveFlatEarthWatch all my other debunks/debates/discussions: http://bit.ly/ProfDaveDebunkEMAIL► [email protected]► http://patreon.com/ProfessorDaveExplainsCheck out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!Amazon: https://amzn.to/2HtNpVHBookshop: https://bit.ly/39cKADMBarnes and Noble: https://bit.ly/3pUjmrn Learn more about your ad choices.

In a recent video I reviewed a Piers Morgan segment that I was initially asked to participate in. It's all about people like Terrence Howard, Candace Owens, and the anti-science/anti-intellectual/anti-establishment fervor that they elicit from the general public. After my commentary on what everyone said on the panel, I closed the video with a short essay that nicely summarizes some of my thoughts on this enormous, potentially apocalyptic problem. Many asked that I upload it separately for ease of sharing. That's this. Please spread this far and wide, maybe it will help!The Piers Morgan video this excerpt is taken from: https://www.youtube.com/watch?v=3_2LqixG9CwWatch my other debunks/debates/discussions: http://bit.ly/ProfDaveDebunkEMAIL► [email protected]► http://patreon.com/ProfessorDaveExplainsCheck out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!Amazon: https://amzn.to/2HtNpVHBookshop: https://bit.ly/39cKADMBarnes and Noble: https://bit.ly/3pUjmrn Learn more about your ad choices.

Continuing with Phylum Chordata we finally reach the amniotes, which we will begin to investigate first by examining synapsids, and in particular Class Mammalia. What are mammals?

Acids! Bases! Conjugate acids! Conjugate bases! We definitely have to be able to label such things, and we should also know how to state which direction in an acid-base equilibrium is preferred. To do this we should know how to tell which acid is stronger, and to do that we have to understand stabilizing factors for the conjugate base, which means we need to understand resonance and electronegativity, which means we need to understand quantum mechanics, which means... oh just watch this.Try all of the organic chemistry practice problems: http://bit.ly/ProfDaveOCPPOrganic Chemistry Tutorials: http://bit.ly/ProfDaveOrgChemEMAIL► [email protected]► http://patreon.com/ProfessorDaveExplainsCheck out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!Amazon: https://amzn.to/2HtNpVHBookshop: https://bit.ly/39cKADMBarnes and Noble: https://bit.ly/3pUjmrn Book Depository: http://bit.ly/3aOVDlT Learn more about your ad choices.

Some ionic compounds are coordinated to a specific number of water molecules in solution. But how many? How can we find out? We can't see molecules! Whatever will we do?

After the success of Apollo 7, all eyes were on the moon, and sending astronauts into lunar orbit. But the decision to do this in the mission immediately following Apollo 7 was a bold and risky move, based on the perceived status of the Soviet space program, which ultimately paid off. Apollo 8 sent astronauts Frank Borman, Jim Lovell, and Bill Anders all the way to the moon, the first humans to ever get so far away from Earth. They orbited the moon ten times, gathering an enormous amount of data to inform the selection of future landing sites, and then returned home safely. The famous photo "Earthrise" was taken on this mission, along with many other incredible images of the Earth from deep space, the first such images ever collected.Script by Jackson TylerWatch the whole Apollo Program playlist: http://bit.ly/ProfDaveApolloClassical Physics Tutorials: http://bit.ly/ProfDavePhysics1Modern Physics Tutorials: http://bit.ly/ProfDavePhysics2Astronomy/Astrophysics Tutorials: http://bit.ly/ProfDaveAstronomyMathematics Tutorials: http://bit.ly/ProfDaveMathsEMAIL► [email protected]► http://patreon.com/ProfessorDaveExplainsCheck out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!Amazon: https://amzn.to/2HtNpVHBookshop: https://bit.ly/39cKADMBarnes and Noble: https://bit.ly/3pUjmrn Learn more about your ad choices.

We've already learned about VSEPR theory, and how to use it to predict the shapes of various molecules. But we didn't cover all of the molecular geometries for certain hybridizations, and we didn't talk about bond angles, so let's do both of those things now, using some neat 3D software!Want to play around with ChemDoodle 3D?
