Answer 1

There were some pretty serious discoveries and developments regarding the use of oil, how to build and control airplanes, how to make machines that could make smaller machines with more accuracy than humans could in the past, transistors, engines to harness and transfer electrical power.

All these things helped accelerate our research and development of other things that made it possible to research and develop things even faster. Up until then we didn’t have a lot of those things.
