Go to consensus.app for a new way to search through primary scientific literature!You know how creationists often blindly reference a particular scholar, as though the things the scholar says somehow substantiate their ridiculous views? These days that scholar is Denis Noble. He's a physiologist who thinks he's debunked Neo-Darwinism and revived the long discarded Lamarckian model of evolution. Spoiler alert: he hasn't. He only offers a pathetic distortion of principles in evolutionary biology which are so disgraceful that it raises the question of who is paying him to do it. Don't worry, all your questions will be answered and all of Noble's ridiculous rhetoric will be dismantled in this video!Special thanks to Zach B.

We know about inverse functions, and we know about trigonometric functions, so it's time to learn about inverse trigonometric functions! These are functions where you plug in valid values that trig functions can possess, and they spit out the angles that produce them. There's a little more to it than that, so let's get into it!Watch the whole Mathematics playlist: http://bit.ly/ProfDaveMathClassical Physics Tutorials: http://bit.ly/ProfDavePhysics1Modern Physics Tutorials: http://bit.ly/ProfDavePhysics2General Chemistry Tutorials: http://bit.ly/ProfDaveGenChemOrganic Chemistry Tutorials: http://bit.ly/ProfDaveOrgChemBiochemistry Tutorials: http://bit.ly/ProfDaveBiochemBiology Tutorials: http://bit.ly/ProfDaveBioEMAIL► [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.
