Cultural revolutions of one kind or another, all dependent on technological achievements, define the 20th century as one hundred years of constant change. Humanity transitioned from the industrial revolution of steam-powered engines to the information revolution of silicon-based computing and cyberspace. Buckminster Fuller discusses what we achieved during his 20th-century lifetime.

Born at the very end of the 19th century, this famous polymath coined the term “Spaceship Earth” and would live until 1983. During his nearly ninety years of life, he would witness things once thought impossible become realized.

Fuller remembered what Earth was like before humans conquered the airwaves, learned how to fly and explored the planet in its entirety.

Our reality explained.

"I suggest to audiences that they say, 'I'm going "outstairs" and "instairs."' At first that sounds strange to them. They all laugh about it. But if they try saying in and out for a few days in fun, they find themselves beginning to realize that they are indeed going inward and outward in respect to the center of Earth, which is our Spaceship Earth. And for the first time they begin to feel real 'reality.'" • Buckminster Fuller
