Professor Dave Explains

Are you tired of algebra yet? Come on, it's fun! Before we dive into graphing, let's just do a little bookkeeping with rational expressions. We have to be able to easily simplify, add, subtract, multiply, and divide these, otherwise the more complex algebra that comes later will be impossible. Don't worry, it's not too bad!

We've made it to our final cross-coupling reaction, the Kumada reaction, developed by Makoto Kumada. This one utilizes Grignard reagents, and nickel chemistry is involved in addition to the standard palladium chemistry. Let's take a look!

Who wants to smash molecules into little bits? A mass spectrometer does, that's who. This is a good technique for corroborating molecular structure, because we can make sure the puzzle pieces fit the right way. Check it out!

Science denial is dangerous no matter who is promoting it, but it's ten times worse when it's coming from people in positions of political power. In February, RFK Jr. was appointed by Donald Trump to act as Secretary of the Department of Health and Human Services, which oversees CDC, NIH, and FDA. Bobby also is famous for profiting from spreading lies about vaccines, denying the germ theory of disease, and just generally being a complete maniac masquerading as someone who cares about public health, largely coasting off of his family name. It's time for everyone to see exactly who this guy is, and this video will be an extremely detailed analysis of his views, behavior, and the policies he has enacted during his very short time in office. Please watch, share with others, and use your voice. It's time to start fighting back.

Did you guys know that flat earthers still exist? It's crazy, right? Despite the "community" being in shambles after the Antarctica trip, all your favorite douchebags like Eric Dubay, David Weiss, and Mark Sargent are still grifting their faces off. The recent Artemis II mission has really set them off, as you can expect. So much footage, so many images, a huge mountain of undeniable proof that the Earth isn't flat. How do you think they'll handle it? In the most intellectually bankrupt manner humanly possible? Bingo. Grab some popcorn and enjoy the show.
