This is one of those concepts that is both simple and mind-bending, so I will being doing my best to explain and explore it for you here. As always, if you have any questions following this discussion, I’m more than happy to engage further in the comments.
This might sound like a philosophical question, but I intend it more like a scientific question. We’ve discussed this somewhat before, like in our post about the universe’s habitable zone, but I want to focus in a little closer on what life really is, on what makes one thing alive and one thing not alive, how we might go about defining the difference, and whether what we call life deserves the distinction we have hitherto applied.
Don't worry: this isn't a post in which I rant about the good ol' days, and how the whole world's just about falling apart in this dilapidated modern age (although maybe I should write one, if I can pop off phrases like "dilapidated modern age"). No, this post is about education, and specifically memorization. I don't know about you, but I hated rote memorization in school, and I still do. Give me papers to read on Heisenberg's Uncertainty Principle or ask me to be able to explain how a Hall Effect Thruster works and I'll happily dive right in, but ask me to memorize the technical parameters of an aircraft that I'll always be able to simply look up if I need them and there will ensue great wailing and gnashing of teeth. Maybe I'm exaggerating a little, but the point is that I am not, and never have been, fond of rote memorization.
