I can't help but get the feeling that dad does not care at all what anyone posts. It would seem that this is just his way of being able to rant about his beliefs without taking anyone else's opinion into account. I must admit I do enjoy your posts and continue to learn from you and others so I guess that is at least one redeeming aspect of his opiniated posts.
Despite his attitude and his twisted sense of truth, I have also learn things from other members too.
My focus in civil engineering and computer science, only taught physics and maths that were related and applicable to these two courses, so the physics and maths were pretty limited.
I have learn far more physics in the last 15 years than I did in my two courses, especially in fields that I have never studied before, such as relativity, quantum mechanics, particle physics, nuclear physics, etc.
During late 1980s to mid-90s, most of civil engineering works involved roadworks, but I have also worked brief stint (2 years) in waters, such as mains and storm-water drains. So I didn't need to learn relativity or quantum mechanics.
And my knowledge in biology was limited to Year 9 high school biology, although I did learn limited stuff about woods and trees, that can be used as building materials in civil engineering, otherwise it is all concrete and steel and asphalt. I had only started learning evolution in 2003-04 from my cousin's old 1st year biology textbook.
Much of what I know now about physics, astronomy and biology, only come from the last 15 to 17 years of my life, outside of formal education, learning what I can and in my own free time, from textbooks and websites (like NASA, ESA, CERN).
And of course, I have learned stuff from members of forums (like here at RF, and from earlier at Free2Codes; I actually met YmirGF at Free2Codes), some are biologists, some are mathematicians and physicists, and we even have a retired archaeologist-anthropologist (metis).
Biology is definitely not my areas of expertise, so I far more comfortable with physics, but what I am learning now has gone well beyond my high school and universities physics.
But I am still learning, whatever I can, whenever I can.
