Problems Plus 7: The Physics of a Block on an Inclined Plane https://youtu.be/0ZJPy-Egfpk - notes - playlist

In this video I go over the physics of a solid block on an inclined plane in terms of the sliding friction, weight, normal force, and applied horizontal force.

Genetics: Genes, Development, and Evolution https://youtu.be/7JC3m7RkZko - notes - playlist

In this video I review the 4 key stages of development of an organism: determination, differentiation, morphogenesis, and growth. I also discuss the role genes play in development or organisms and resulting divergent, parallel, or convergent evolution of species.

Genetics: Genes, Development, and Evolution https://youtu.be/4akLCQMYewc - notes - playlist

In this video I provide a quick overview of evolutionary biology, its history, and important processes that affect the genetic characteristics passed down to populations.

Evolutionary Biology: Phylogenies, Homology, and Taxonomy https://youtu.be/apZQ35bMOcE - notes - playlist

In this video I go over phylogenies, which represent the evolutionary history of a group of organisms or their genes.

Evolutionary Biology: Speciation, Reproductive Isolation, and Hybrids https://youtu.be/u_ygO92LgmY - notes - playlist

In this video, I explain speciation, the process by which one lineage splits into two independent lineages that evolve separately. For speciation to occur, reproductive isolation is required, which can result from physical barriers (like geographic separation) or genetic incompatibilities.

Evolutionary Biology: History of Life, Mass Extinction Events, and Dinosaurs https://youtu.be/iUOm3L3dNvg - notes - playlist

In this video, I cover the evolutionary history of life on Earth, which traces back to a universal common ancestor that lived around 3.5 billion years ago.

Biological Diversity: Bacteria, Archaea, and Eutrophication https://youtu.be/KOgugykmT6Q - notes - playlist

In this video I go over bacteria and archaea which comprise two large and separate domains of prokaryotic microorganisms.

Biological Diversity: Protists https://youtu.be/3GV0vZYZ9tM - notes - playlist

In this video I discuss protists, which are eukaryotic organisms that are not animals, plants, or fungi.

🔬#MESExperiments 42: Gyroscopes Can Rise Upwards AND Downwards https://youtu.be/nqeQuAwVIqo - Notes - Playlist (Hive)

In this experiment I show that a gyroscope can precess upwards on its own, but if a counterweight is added, it can precess downwards while torquing the counterweight upwards.

Plant Diversity: Flowering Plants, Gymnosperms, Bryophytes, Pollination https://youtu.be/NvwZyXjGND8 - notes - playlist

In this video I discuss the wide variety of plants, which are mainly eukaryotes that obtain energy from the Sun via photosynthesis.

Fungi: Chitin, Yeasts, Molds, Mushrooms, and Decomposition https://youtu.be/8wLOtbZNFi0 - notes - playlist

In this video, I discuss fungi, a group of eukaryotic organisms known for their role as decomposers and for containing the long-chain polymer chitin in their cell walls.

🔬#MESExperiments 43: Dr. Irwin Moon Fries an Egg on a COLD Stove using High Voltage AC https://youtu.be/-JiwkekFBLQ - Notes - Playlist (Hive)

In this experiment I show a clip from the late Dr. Irwin Moon's 1956 science video series in which he demonstrates the selective power of high voltage alternating current (AC) through a copper coil: steel wool exploding, eggs frying instantly, yet paper and hands don't burn!

Animal Diversity: Sponges, Chordates, Vertebrates, Blastulation, Food Chain https://youtu.be/4SV5Ep-cFEY - notes - playlist

In this video, I discuss the wide variety of animals, which are multicellular eukaryotic organisms. Animals, including humans, almost universally consume organic material, breathe oxygen, and develop from a hollow sphere of cells called the blastula.

🔬#MESExperiments 44: Dr. Irwin Moon Sends a MILLION Volts of Electricity Through His Body! https://youtu.be/klVElJzqOpI - Notes - Playlist (Hive)

In this experiment I have uploaded another one of Dr. Irwin Moon's experiments, this time his wildest one yet: sending a million volts of alternating current (AC) electricity directly through his body!

An Elusive Limit Questions 1, 2: Limit Depends on Calculator Precision https://youtu.be/ULTOgc1cuAI - notes - playlist

In this video I go over a very interesting trigonometric (and inverse trigonometric) function whose limit as x approaches 0 is unclear and gives different values depending on the calculator you use.

An Elusive Limit Question 3: Using L'Hospital's Rule 7 Times in a Row (Using Wolfram Alpha) https://youtu.be/LRLahyO4SVk - notes - playlist

In this video I go over the previous difficult trigonometric (and inverse trigonometric) function and this some apply L'Hospital's Rule to show that its limit as x approaches 0 is equal to 1.

An Elusive Limit Question 4-5: Evaluating the Limit using Taylor Series (and Wolfram Alpha) https://youtu.be/GEfzOVaPwAE - notes - playlist

In this video I go over the earlier trigonometric (and inverse trigonometric) limit and solve it by writing the numerator and denominator as Taylor series.

Planck's Constant is the Quantum of Energy and NOT "Quantum of Action" https://youtu.be/W6-FvG8OBAk - notes - playlist

In this video I demonstrate FractalWoman's Modified Unit Analysis (MUA) and show that Planck's relation in Quantum Mechanics is unbalanced and leads to the misguided notion of "photons".

An Elusive Limit Question 6: Subtracting Nearly Identical Numbers can BREAK Calculators! https://youtu.be/GEfzOVaPwAE - notes - playlist

In this video I explain that the reason calculators gave an unclear limit for the complicated trigonometric function is because every term was nearly identical, to the point where subtracting them resulted in a difference too small for the precision of most calculators.
