People who love this should consider visiting the Institute and Museum of the History of Science in Florence (now rebranded the Galileo Museum for what I assume are marketing reasons :P).

It's heaven for science nerds.

Armillary spheres (including a room sized one from the 1500s), all manner of astrolabes, astronomical clocks, hand ground lenses and microscopes and telescopes and Galileo's actual middle finger (https://en.wikipedia.org/wiki/Galileo's_middle_finger), a tabula affinitatum, michelangelo's compasses, even an organum mathematicum!!!!!
