"Bones: Structure and Types We've got the skin covered so now let's take a look at bones These give structure to the body. Bone is a type of tissue but an actual complete bone is an organ because there is lots of stuff inside besides bone.

"Bret and Eric Weinstein: Brothers in Fraudulence 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."

"Introduction to Economics What is economics Yes of course it has to do with money. But beyond the concepts that we might immediately think of like taxes gross domestic product and the stock market which belong to macroeconomics we must also understand microeconomics. Deconstructing the personal decisions we make every day on the basis of scarcity of goods and resources will help us get a better understanding of what economics is fundamentally about such that we can then learn about larger concepts in a relatable way. And don't forget personal economics like banking and credit cards that's all"

"No Sabine Science is Not Failing Last week I put out a video about another science communicator named Sabine Hossenfelder. In it I criticized some unprofessional behavior regarding her choice of titles thumbnails and generalized deceptive anti-science rhetoric which has clearly been fueling science denial among the public in large numbers. While many people were relieved to finally hear someone say these things out loud a portion of the internet lost their minds over it leaving infantile criticism which only demonstrated that they didn't actually watch the video or understand the point of it."

"Newton's Law of Universal Gravitation You thought we were all done with Newton didn't you You figured that three laws are enough for any scientist. Well think again Newton was quite the champ and his work with gravity was revolutionary. I mean the guy invented calculus so that he could do his work on gravity. So when he INVENTED CALCULUS he did it just so that math could exist that was complicated enough to do stuff that was more important than inventing calculus. Think about that for a while. Then watch this. Then think about it again. See more NASA footage at https://nssdc.gsfc.nasa.gov"

"The Isolation of Natural Products: Morphine and Other Alkaloids In the early 19th century we were still in the habit of searching for plants with medicinal properties. But we were finally beginning to develop the capacity to identify active ingredients within those plants isolate them and purify them such that they could be administered in the form of pills and powders. The class of molecules that initiated this sea change was alkaloids the most notable of which was morphine. How did we identify morphine and ascertain its properties Once isolated how was it tested It's actually a pretty crazy"

"Wavefunction Properties Normalization and Expectation Values We are beginning to get a glimpse of quantum mechanical principles from a rigorous mathematical perspective. Now that we know how to use operators in conjunction with wavefunctions let's get a better sense of what wavefunctions actually are and how their superpositions can describe the parameters of a quantum particle. Along with this we will learn about bra-ket notation how to normalize wavefunctions and also calculate both inner products and expectation values all of which will help us get a better perspective on quantum systems."

"Types of Photosynthesis in Plants: C3 C4 and CAM We learned about photosynthesis over in the biochemistry series. But now that we are taking a closer look at plants we need to learn about the different types of photosynthesis that exist within the plant kingdom. The version we learned already is found in C3 plants and it is the most common type but we also have to learn about C4 plants and CAM plants. These plants have evolved slightly different pathways in order to respond to environmental pressures. Let's see how this works now Script by Ryan Helcoski More general photosynthesis tutorial:"

"Introduction to Biology: What is Life After we learn chemistry and biochemistry we are ready for biology In this course we extend our understanding of molecules to encompass an entire cell and everything inside it. This is a huge step in complexity and we will even talk about how the first cells may have come about. First just a little introduction to whet your whistle Watch the whole Biology/Genetics playlist: http://bit.ly/ProfDaveBio General Chemistry Tutorials: http://bit.ly/ProfDaveGenChem Organic Chemistry Tutorials: http://bit.ly/ProfDaveOrgChem Biochemistry Tutorials:"

"RFK Jr. is Dangerously Stupid Go to consensus.app for a new way to search through primary scientific literature 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"

"Gene Expression Analysis and DNA Microarray Assays If we want to understand a biological organism we turn to the expression of its genome. Which genes are being expressed and in which cells and when How does this differ between a normal cell and a cancer cell We have incredibly sophisticated techniques to investigate these questions and the most indispensable is the DNA microarray assay. This apparatus is even more useful than it is colorful so let's see how this works now. Watch the whole Biology/Genetics playlist: http://bit.ly/ProfDaveBio General Chemistry Tutorials:"

"Regulation of Gene Expression: Operons Epigenetics and Transcription Factors We learned about gene expression in biochemistry which is comprised of transcription and translation and referred to as the "central dogma" of molecular biology. But how is this process regulated How does a cell know which genes to express and when Well it's pretty complicated but let's just get our feet wet by looking at operons epigenetics and transcription factors Watch the whole Biology/Genetics playlist: http://bit.ly/ProfDaveBio General Chemistry Tutorials: http://bit.ly/ProfDaveGenChem Organic Chemistry"

"Response to Globebusters - The Earth Still Isn't Flat Last week I posted a video about how we know the Earth is round from the perspective of modern astronomy. The Flat Earth community did not like it one bit and the channel "Globebusters" decided to talk for three hours on their livestream about how stupid my video is and how stupid I am. I didn't really appreciate that so I decided to make a video about their video to illustrate precisely how little they know about science and to further reinforce how utterly absurd the Flat Earth "model" is as well as some of the finer points about the"

"The Great Big Pseudoarcheology Debunk (Graham Hancock Dan Richards Jimmy Corsetti) What is pseudoarcheology Just as there is pseudoscience pertaining to physics chemistry biology and medicine there is pseudoscience that bastardizes archeology as well. Remember Ancient Aliens on the History Channel We all used to make fun of that. But now millions of people have fallen for this ridiculous trend and they primarily worship a disgusting fraud named Graham Hancock as well as a handful of copycat grifters such as Dan Richards and Jimmy Corsetti who are following in Graham's footsteps. What do these"
