One might consider that a deep running current in "natural philosophy" and physics, as it was later called, was the search for something to which the objectivist attitude could safely be applied. Democritus posited atoms as fundamental unchanging particles.The 19th century chemists and Lord Kelvin reported evidence that he was right, as long as you suitably modified the meaning of "atom".
Then electrons and other "elementary particles" began to be seen.
Nowadays at CERN protons, smashed together near the speed of light, result in a veritable zoo of particles, most of which "decay" within microseconds into other species. We are further from objectivity than Democritus was at the beginning of the hunt.

Of course one of Newton's tours de force was the application of the objectivist idea to things that certainly changed with time, but at a slow enough rate they could be objectified.
He calculated the orbits of the moon and planets by abstracting from the heavenly bodies all their properties except mass and position. Picturing the sun and its satellites as points with constant mass, and gravity as a force acting instantaneously at a distance, was accurate enough to make succeeding generations question the existence of God.
Despite our knowledge of relativity, Newtonian mechanics was accurate enough to get the astronauts safely to the moon and back.
Unfortunately, no time for me to collect anything (situated where just the past 5 weeks alone meant 50% inflation already. Hell knows how it´s going to end).
However, having had a brand new book of mine unseeingly shredded by caretaker of a publishing house, I definitely appreciate people who keep books even if they can only be sold for one single cent. Hat off to them!

Speaking of which, July 20 this year will mark the 50th anniversary of the moon landing. I am currently reading a recently published book entitled "American Moonshot: John F. Kennedy and the Great Space Race." by the historian Douglas Brinkley. It is very good, and begins with Robert Goddard and initial rocketry, carries on through World War II with Kennedy in the Pacific and Wernher von Braun developing the V-1 and V-2, the post-war Cold War, Sputnik, and a concentration on the Kennedy presidency and the decision (and internal US government debate) to land a man on the moon within ten years time.
Brinkley is especially interesting when he discusses Wernher von Braun. Von Braun and the Nazi scientists brought over under "Operation Paperclip" were of course instrumental in developing our program. It was known from the very beginning that von Braun and the others were hardly angels. Brinkley is especially hard on von Braun, emphasizing that he was a colonel in the SS and a Nazi. He also made extensive use of slave labor at Peenemunde and later the area in the Harz Mountains where he developed and tested the V-2. Nevertheless, we were lucky to get him, as he was far more capable than those that the Soviets managed to get after the war, although the Soviets developed their space program pretty quickly.
