Technological revolutions have shaped our world. Without past inventions and historical landmarks, contemporary society would only be a shadow of its current self. Without a number of the worlds inventions, none of what we experience today would be possible. I say this as I type on a laptop, listen to music through a bluetooth speaker and drink mineral water out of a bottle.
See what I mean?
Inventions that are technological revolutions can be anything, from the iron nail to the printing press, the wheel to the shipping container, the smartphone to the internet.
