Ask HN: How to increase your exposure to technologies?

Looking for a Tour De Force covering tools, mechanisms, processes, etc. that have either greatly impacted us OR that simply are great examples of clever ingenuity.

The more to-the-point, the better. Preferably focusing less on the historical developments and more on the "one time someone figured out they could do X with Y and it is clever because Z"

Some large common examples: the loom, the printing press, internal combustion engine, the transistor, clocks anchor escapement, materials, ...

Encyclopedias, podcasts, videos, ... even museums could be good pointers. I realize the question may be too broad but the point is to increase exposure to technologies.
