around us, or the broader universe, to being able to travel through space, using reason to ferret out the hidden secrets
of how the world works, from physics to chemistry to biology, we worked out the tools and rules underpinning it all, mathematics, and now we can see objects that are almost impossibly small, the very tiniest building blocks
of matter, (or at least we can examine them, even if you can't «see» them because you're using something other than your eyes and photons to view them) to the very farthest objects, the
