Application of E=MC2 to Life


An article published in 2016 on Interesting Engineering summarized a clear understanding of Einstein's Theory of Relativity and what they see as a "mathematical solution to an esoteric problem." 😄  Basically, there is no such thing as an "absolute" frame of reference because everything is in relation to something else.  I guess that would be applicable to the construction of our identity and understanding of the world.  There is a point of reference/root/starting point to everything that shapes who we are.  As much as we'd like to think we are individuals with unique identities, even that idea is informed by another person/culture/ideology/etc.  

Four Forces & Gravity


The four "forces" are the fundamental laws of nature and at the core of everything in the universe. This article from Forbes magazine clarified some of my questions about the four forces from our class discussion: 1) strong nuclear force holds atomic nuclei and individual protons and neutrons together 2) electromagnetic forces attracts and repels charged particles, causes electric current and binds atoms together, 3) weak nuclear force is responsible for transmutation and some types of radioactive decay and 4) gravity is the force that binds: the Earth, Solar System, stars and galaxies together. 😲

Chemistry of Life Discussion + Reflection Our discussion on air pollution particles found in hearts of city dwellers was alarming.  I was aware that air quality in massive cities like Mumbai and Beijing had poor air quality, but the article we read in class stated that more than 90% of the world population lives with toxic air. We are so fortunate in the Bay Area that our air quality is great, though the fires have had a significant impact on it these past few years.  I didn't realize how sensitive my lungs were to the fires. I had asthma growing up and it hasn't bothered me until the fires.  I started thinking about that business that sold canned air in China.  What started off as a gimmick selling a ziplock bag of air for about a dollar, their sales sky rocketed after Chinese consumers began to buy it online. You can find the article here .  It boggles my mind that our society is at a point where they are harvesting and profiting off air. AIR?...

[BIOLOGY | Week #3] Human & Chimp Genes + Genetic Evolution

Human + Chimp Genes and Genetic Evolution "99.4% of the most critical DNA sites are identical in human and chimps genes" In response to the quote above, I believe humans are either descendants of chimps or share a common ancestor. P erhaps over time, a genetic mutation occurred in a generation of chimpanzees and the human species are products of that change.  Our genetic similarities to chimps can offer a useful key into understanding the biological and evolutionary traits of humans; it seems we are just scratching the surface in understanding what makes us human. I was unable to access the link provided on human genetic evolution, but found an interesting article published by Big Think on four beneficial evolutionary mutations that humans are currently undergoing.  What intrigued me is their stance on mutations as a more positive outlook on genetic evolution. For instance, there is a small community in Italy who carry a mutant version of a protein gene ca...

Introduction Greeting ACCHS Western Sciences Community,     My name is Verma Zapanta and I am a first year student at ACCHS. Although I've been attending the course since the beginning of the trimester, I just enrolled in the class and am slowly catching up with the workload in all the Western Science courses that Larry is teaching. =) I worked in education for ten years prior to attending ACCHS as a history teacher, college professor and in youth leadership development.  I transitioned out of teaching because the work became unsustainable and had a significant impact on my wellbeing. I found myself drawn to mental health work and holistic medicine because it supported my own healing.  Acupuncture was the introduction to other modalities of healing and re-connected me to the medicines that exist in my ancestral land of the Philippines.  My goal as a practitioner is to not only practice Chinese medicine, but to continue conversations on wellness within spac...
