Middle Genus Homo (Muddle in the Middle)

We've discussed the earliest members of genus Homo, but we haven't reached modern humans yet. The middle Pleistocene is known as "the muddle in the middle" because numerous Homo species are known from this time, but their relationships are not yet well-understood. Homo ergaster, Homo heidelbergensis, Homo rhodesiensis, Homo antecessor, Homo bodoensis, what were their morphologies, and what do we know about them?

We've learned how stars form, and we've gone over some different types of stars, like main sequence stars, red giants, and white dwarfs. But a star will move between these categories over its lifetime. How does that happen, exactly? And what is leftover when a star dies? A white dwarf? A neutron star? A black hole? What are these objects? Let's answer all of these questions and more by analyzing the life cycle of a few different star types!Watch the whole Astronomy/Astrophysics playlist: http://bit.ly/ProfDaveAstronomyClassical Physics Tutorials: http://bit.ly/ProfDavePhysics1Modern Physics Tutorials: http://bit.ly/ProfDavePhysics2Mathematics Tutorials: http://bit.ly/ProfDaveMathsGeneral 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.

We've learned how to use calculus to find the area under a curve, but areas have only two dimensions. Can we work with three dimensions too? Yes we can! We can find the volume of things called solids of revolution, again by integration, it's just slightly more involved.

Of all the people on the internet pretending to be geniuses, none are more aggravating than the Weinstein brothers. You have Bret, a fake biologist who tells everyone he deserves a Nobel prize for no reason, and really just spreads misinformation about biomedical topics on the internet which get people killed. Then you have Eric, a fake physicist who tells everyone he deserves a Nobel prize for no reason, and really just spreads anti-establishment tripe all over the internet that degrades public perception of academia and the scientific community. Basically, these guys are gigantic assholes. But they've managed to convince so many people that they're brilliant renegades who have been shunned by the establishment, because their truth is just too hot to handle. How are they able to do this, and can their fans be shown what massive frauds they really are?
