I had a similar revelation for structural biology, applying the physics I learned for bridges and buildings to microscopic proteins. They are structurally like a cathedral built by a blind and deranged architect. The fact that mechanically bend, pivot, and move like a complex machine at a micro scale to do real work is the most sci-fi thing I can conceive of.
Think of a even a simple walking protein like Kinesin [1]. What is not shown in the video is that this is all happening in a hurricane of molecules battering it from all sides. Each part of the structure is being pushed, pulled, bent, robot made out of sticks and rubber bands.
The other word missing is "cheap". Proteins are under a massive selection pressure: many thermodynamic reactions in fundamental bits of biology are as thermodynamically efficient as they can be, else some slightly more efficient mutant would have out-competed it aeons ago.
I became interested in biology as a physicist when I realised that all of the problems, on some level, boil down to putting a load of lego pieces in a box, shaking it up with some energy not terribly different to k_B T, and getting a fully-formed, self-replicating lego models out the other end. It's all physics. It's all utterly incomprehensibly mind-bogglingly complex with layers of complexity wrapped around each other, and far out of the realms of either physics or chemistry to compute completely. It's why I work at the intersection of the two fields.
Another famous paper, often-mentioned, related to this is "How a biologist would fix a transistor radio", essentially armed only with a shotgun. The tools of modern molecular biology may be scalpels rather than shotguns, but still, the idea is arguably the same.
I was about two sentences into the parent comment when these videos came to mind. If I had seen just about anything done by Drew Berry when I was in middle school I probably would be in a completely different career:
