Christopher Nolan’s 2020 scifi movie Tenet has something they call inversion, which allows objects to be sent backward in time. This is sort of hand-wavingly explained as either reversing entropy or objects moving backward in time. In this video, I go through the science behind these ideas, including reversing entropy, moving backward through time, and CPT symmetry.
A series of videos explaining physics and math in simple, intuitive language. If you think you’re an idiot when it comes to learning these tough subjects, you might benefit by learning from a fellow idiot.
This series of videos goes in-depth into the biochemistry and physiology of nutrition and metabolism. Starting with a quick primer on the general chemistry concepts needed to understand the basics of biochemistry and metabolism, I then go on to introduce all the key players involved – the macronutrients (carbohydrates, lipids and fats, amino acids and protein, and then nucleic acids and DNA) and micronutrients. After going through the biosynthesis of all the vitamins, as well as chemical properties of the minerals, I will then go into digestion, absorption, and metabolism, following the various molecules and metabolites throughout the body.
I made a Youtube video explaining the effects that SARS-CoV-2 has on the cardiovascular system. The SARS-CoV-2 virus is named after being a severe acute respiratory syndrome, indicating its connection to breathing and the lungs. But studies show that the Coronavirus also has a potential for devastating cardiovascular effects, resulting in inflammation, coagulopathy, thrombosis, and (interestingly enough) thrombocytopenia. The risk of these cardiovascular effects is increased by pre-existing conditions, such as obesity, atherosclerosis, and diabetes.
The possible detection of phosphines in the atmosphere of the planet Venus has sparked interest in possible biogenesis of the compound. In other words, there may be microscopic extraterrestrial organisms living up in the Venusian clouds. This would be an amazing discovery. But, it also raises the question about what sort of biochemistry such organisms (if they exist) utilize in their Venusian flavor of metabolism. Here I will make some speculations about this.
The laws of physics, to the amateur science enthusiast, can sometimes seem like a disparate bunch of equations without any real underlying connection. That doesn’t seem good enough, so you dig a little deeper, and soon discover that there is this thing called Lie Theory, with Lie Groups and Lie Algebras. You want to find out what all this is, and the only things you can find just give you another bunch of equations and leave it there as if those unexplained symbols are good enough for you to understand. Well, I’m at that point, and here I am going to talk about Lie Theory and its connection to physics in hopes that explaining things simply and intuitively will help me to better understand it – and if that helps any readers understand it better, that’s good, too.
Einstein is one of the most famous scientists in history, and one of the most famous equations of this most famous scientist is E=mc2 which, although famous, most people don’t know what it means. It is, of course, the equivalence of mass and energy. But what does that mean?
If you have not yet heard of “the” Coronavirus you must not be paying attention. However, knowing about it does not necessarily mean you are informed about it. There seems to be a lot of misinformation regarding this disease. Perhaps here I can make things a little more clear.
