"Antitussives: Halting the Coughing Reflex (Codeine Dextromethorphan Tessalon) The next class of drugs is antitussives and these are intended to halt the cough reflex. Tussis or coughing is a complex physiological response to irritants in the airways and certain drugs seek to dampen this response when harmful to a patient. Let's discuss the pathways responsible for tussis and the types of drugs that can interact with these pathways and inhibit them such as codeine dextromethorphan and Tessalon.

These are like functions that take in coordinates and give back vectors so there will be a vector associated with every single point in the field. There are two things we must be able to do with vector fields as well which involve the del operator and either the dot product or the cross product with the vector field. These give us the divergence and the curl of the vector field respectively. Let's learn all about these operations now. Script by Howard Whittle Watch"

Plenty had to happen to get us to that point but the most amazing stuff is yet to come Shortly after Einstein did his best work a guy named Edwin Hubble demonstrated that what we thought was the entire universe was actually just one little island of stars out of billions of other galaxies. And that's just the tip of the iceberg The universe is also expanding What does all this mean for cosmology Let's find out. Watch the whole Astronomy/Astrophysics playlist:"

"Exposing Discovery Institute Part 1: Casey Luskin Have you heard of the Discovery Institute Have you fallen under the impression that they know what they are talking about or can be considered an even remotely legitimate source of information Well you've come to right place. They aren't. They're a propaganda mill and all of their content is full of lies. They hide behind a paper-thin roster of scientists who have deluded themselves into dishonestly preaching outside of their expertise and they blatantly misrepresent any scientific research or scientists they are referring to. Constantly."

"Particle Decay Rates and Cross Sections To substantiate the Standard Model of Particle Physics we look for certain kinds of particle interactions and other events including particle decay. Why do decay events produce the kinds of particles they produce and why do particles decay at all It's a complicated question but let's talk about it Script by Andrew Mattson Physics PhD Student at Johns Hopkins University Watch the whole Modern Physics playlist: http://bit.ly/ProfDavePhysics2 Classical Physics Tutorials: http://bit.ly/ProfDavePhysics1 Mathematics Tutorials: http://bit.ly/ProfDaveMaths"

"Pierre Kory: The Ivermectin Fraud Whose Lies Killed Thousands After my live vaccine debate with Steve Kirsch and Pierre Kory I promised to even further expose them both with their own videos. With Steve already covered let's further expose Pierre Kory. This is the jerk that is responsible for the ivermectin craze during the pandemic. He claimed it was a miracle drug that would both cure and prevent COVID. Amazing Except it did neither of those things. At all. But thousands of people believed him some overdosed and died from ivermectin and thousands of people delayed legitimate care waiting"

"The [--] Things That All Flat Earthers Say So it's been a minute since I made my response to the Globebusters and for two months now I've had to listen to flat earthers spew the same nonsense in the comment section of that video day after day. Now that I'm intimately familiar with their most popular and most ridiculous talking points I thought I would put them all together in one clip for a vigorous debunking. My original flat earth video: https://www.youtube.com/watchv=tC5RalYWZ5Y My response to the Globebusters: https://www.youtube.com/watchv=JDy95_eNPzM How to actually calculate earth's"

"Exposing Discovery Institute Part 3: Michael Behe Continuing this series exposing all the frauds at the religious propaganda mill "Discovery Institute" we arrive at Michael Behe. He became famous for his concept of "irreducible complexity" which is pretty much the go-to creationist argument. Unfortunately for them it's very stupid. Everything Behe says in his three books is very stupid in fact. In this video I go through his books and explain how stupid they are for all to see even those without a background in evolutionary biology. Enjoy Check out the great creationism debunking channel"
