WEEK TWO - POST THREE

My reaction to this weeks teachings isn't anything significant. No real new learning concerning physics was had. I was already aware of the subjects concerning pendulums and weight having no effect on the rate at which something falls. Although the historical aspect of when these discoveries were had was an interesting fact. I was aware but not of the specifics concerning these discoveries being had in the last 500 years. I find it surprising that the lot of our things that we take for fact now and the ideas that our society are built from, came to fruition within the last few centuries.
What age of science are we currently in?
What scientific or technological advancement had the most impact on our understanding of the universe within the previous 100 years?
