I was taught to always read and continue to educate myself. I respect knowledge, research, and Academia. I have a great admiration for people with PHD's and for those without college degrees. Having learned a great deal from varying disciplines. Many years ago, I read a book about sharing vaccines across borders and it really made me think. The older I get, I have differing thoughts. I've endeavored to learn new subject matter and expand my horizons. However; there is the old adage "The more I learn, the less I know." I've noticed that certain entities hoard knowledge for $$$$. I understand, but don't agree it's the what the world is. For instance, I've located several books on Tribology, but the cost for PDF's are astronomical. These docs are antiquated too. PLEASE, I DON"T want a topic about politics, just sharing knowledge. (Adhere to forum rules please.) I've learned how to ask specific/direct questions to people/corporations. Most hide behind "Proprietary." (Not asking for chemical recipe. Nor, would I would understand it. Lol.) While I 'm only trying to take good care of my vehicle or home. Or they deflect and never answer the question. I was reading a recent thread and someone commented about how a certain group of individuals obtain research papers and publish them. *I don't advocate hacking or taking without permission. I reside in a place, where there are retired scientists and have had varying conversations. All tell me about inadvertent discoveries (technology) that were never released that could have helped humanity or certainly saved lives (auto/aero crashes). Or tech, reserved for dignitaries, heads of State. Or a Chemist discloses that they signed a Non Disclosure Agreement and won't discuss a certain additive (anything) on the internet. I don't expect a Chevron Chemist to betray their employer or a Scientist at Oak Ridge Labs (just example) to betray her/his Country. Civilians have certainly benefited from NASA et al. Apparently, scientists (courtesy NASA, historical archives) are looking at penguin bovine from space. So, there is sharing a bit and this is great. Or great public relations. There have been scientists imprisoned for sharing knowledge with fellow scientist(s) in the interest of science, not $$$$/espionage. At what point does knowledge become classified and not for public consumption? I DONT want to discuss politics or govts, but knowledge for everyone. Khan Academy, Library of Congress, via Internet are wonderful, among others. What do scientists (retired/employed) and others think? If you can't post true beliefs, just topic for inner thought. Thank you!
