🔬#MESExperiments 51: Magnets in Repulsion Atwood Machine Balcony Drop Tests https://youtu.be/IcGo9mooyo8

In this experiment I repeat the Atwood Machine drop tests but this time do it from my balcony at a height of about 14 feet. Surprisingly, the drop tests show no significant difference for the nonmagnets, magnets in attraction, or the magnets in repulsion.

Definition of Derivative for Vector Functions https://youtu.be/LAXaiYA5p1k

In this video I go over the definition of derivative for a vector function, which is very similar to the definition for real valued functions. The derivative of a vector function is defined as the limit as h approaches zero of the secant vector (difference of two vectors separated by incrementing the parameter t by h) divided h. As h approaches zero the secant vector approaches a vector that is parallel to the tangent vector to the curve.

Derivatives and Integrals of Vector Functions https://youtu.be/YT4QJczx8KI

In this video I go further into vector functions and this time show how to obtain their derivatives and integrals. The definition of derivative for a vector function is much the same as with a real valued function, but the difference is that we apply this definition to each component of the vector function. Likewise, integration is also similar to real valued functions but the integral of each component is solved. This will be the basis for future videos when I cover velocity and acceleration of planetary bodies so stay tuned for that!

MES Livestream 105: Bart Sibrel Discusses the Moon Landing https://youtu.be/EUm2oD5xXNk

Moon Landing researcher Bart Sibrel joins the show to discuss his history covering the Apollo Moon Landings, including confronting the Astronauts themselves about whether they actually flew up to the Moon!

Animal Form and Function: Immune System https://youtu.be/xEffS5ZV47M

In this video I go over the mainstream theory of the immune system, which is a network of biological processes that detects and responds pathogens entering an organism. Nearly all organisms have some sort of immune system, while jawed vertebrates (including humans) have sophisticated defense mechanisms and the ability to adapt to recognize previously encountered pathogens. The innate immune system is a rapid and broad defense mechanism, which includes phagocytosis to engulf large foreign particles. The adaptive immune system involves specialized white blood cells (killer cells and T / B lymphocytes) which can recognize unique molecules on pathogens (called antigens) via Y-shaped proteins called antibodies. This immunological memory is the basis of vaccination.

Animal Form and Function: Development https://youtu.be/uKx4DDLLSEU

In this video I go over a quick overview of animal development, which starts from the formation of the zygote through the fusion of a sperm and egg cell during fertilization. The zygote then rapidly divides and forms a ball of similar cells called a blastula. Follows next is gastrulation, in which the blastula gets converted into the three germ layers: endoderm, mesoderm, and ectoderm. These three germ layers then form the internal organs.
