120 years ago, we had no model of the atom, no quantum theory, no relativity, and only the first hints of figuring out radioactivity. Yet we were able to split the atom in 1942, create the MOSFET in 1959, and started launching the first GPS satellites in 1978. It's hard to express how much progress we've made in such a small amount of time relative to the rest of history. It's a god damn miracle.
