The size of the universe; can we really perceive it?; Is reality a real thing? Where I (Ron) am now

It was there in the earliest anaerobic prokaryotes, driving… Continue reading

‘Healthcare’ is a disingenuous misnomer
97.5% for ‘cure’, 2.5% for prevention Ron addresses Claude: It is my opinion that “healthcare,”in the current sociopolitical context,is a misnomer. We are really talking about medical care (including prescribed pharmaceuticals), hospital care, and care by others thataddresses real and perceived problems of the body and psyche. ‘Health care,”in my opinion,is what people do, individually… Continue reading
I began my journey in 1937, in San Francisco. I completed my formal education in 1965 and have continued educating myself — through fully living, extensive reading and travel, and decades of writing, including in several blogs.

Since then, I began querying several online AI services on topics under the rubric “Life, the Universe and Everything” — with acknowledgment to Douglas Adams for the phrase. I settled on Claude.ai as my preferred interlocutor for wide-ranging conversations on quantum mechanics, consciousness, the origins and development of life, and more. This blog is the result.
