Air-conditioning was first invented 117 years ago in 1902 by Willis Carrier in Brooklyn, New York. Carrier invented the unit for a local publishing business, which was having problems caused by the hot and humid conditions in their factory.

That ruined the alignment of colors on the printed page—causing financial losses.
What is the phenomenon of time price declining proportionally faster than the population increases?
We call the phenomenon of the time price declining proportionally faster than the population increases “superabundance.” To learn more about “superabundance, ” check out HumanProgress.org’s new Simon Project website.

Rather than causing scarcity, additional people make goods and resources more abundant.
