In college, I read Thomas Kuhn's "The Structure of Scientific Revolutions." In it he popularized the term "paradigm shift" for insights that forever change the framework in which we view the world.
An example is Copernicus's upending of the Ptolemaic cosmology with a helio-centric model. Just think: before Copernicus, the term "solar system" didn't even exist. Now it's second nature to all of us. Another example is Einstein's upending of Newtonian gravity with general relativity. Just think: before Einstein, the word spacetime didn't even exist. Now it's...well, still not second nature. Relativity is still impossible to wrap our minds around, even a century after Einstein, but it has fundamentally changed science.
Thomas Kuhn's work had a big impact on my formative thinking. That's maybe too portentous an introduction for what I'm about to say I learned today, but I'll say it anyway. In all the commentary on Uvalde, one comment (actually a Tweetstorm) has the potential of causing a paradigm shift in my worldview of law enforcement and public safety.


I didn’t have a religion, and I didn’t do team sports, and for a long time orchestra had been the only place where I felt like part of something bigger than I was, where I was able to strive and at the same time to forget myself. The loss of that feeling was extremely painful. It would have been bad enough to be someplace where there were no orchestras, but it was even worse to know that there was one, and lots of people were in it—just not me. I dreamed about it almost every night."
