Answer:
Explanation: I wont be able to help you with the entire essay, but here is a good introduction paragraph you can build off of.
Technology has always defined human history, from the domestication of the humble horse to instantaneous communication that spans the globe. Even over the past century, technology has changed and improved at such an exponential rate that people from those times couldn't possibly have dreamed of. Although technology can be applied to many fields of human civilization, the advancements of aviation, communication, and warfare really stick out as something noteworthy in the technological advancements over the past century.
To help you a little more, you can maybe talk about how we went from the first planes by the Wright Brothers to the Nazis making the first fighter jets to landing on the Moon and the ISS for aviation. As for communication, you can start at the telegram and Morse code transmissions to radio, television, early computers, and then the internet and smartphones for communication. Lastly, warfare is a vague subject, but over the 1900's we saw the invention of the shotgun, war planes (see the aviation paragraph), tanks, and the nuclear bombs that defined global politics throughout the 2nd half of the 20th century.
Hope this helps!
