I know that everything get evolve more once any specific thing get breakthrough boundaries and get adapted by mass of the populations.
I am curious in case of what are those key inventions that define the ages or era of overall engineering history.
Ancient Civilizations:
Medieval and Renaissance Period:
Industrial Revolution (18th and 19th centuries):
20th Century:
21st Century:
These inventions were pivotal in shaping the course of human history and laid the groundwork for future engineering advancements.
Of course not all of above are inventions but some of them are representing series of inventions but listing them as an single invention will make this answer way beyond longer. so ....
