Big Bang Theory Galileo and Copernicus were sort of
right, but it’s not that simple.
• … and we are sort of insignificant
Psychology We can even scientifically study
how the brain works.
Paradigm Shift So how did new scientific paradigms
transform human understanding of the world?
Which of these ideas had the biggest impact? Why?
Green Revolution Post WWII population explosion
Lots of babies Smallpox eradicated New technology/sanitation decreased
malaria, cholera, typhoid, tuberculosis, and plague
Medical innovations: polio vaccine, antibiotics, artificial heart
Economists project world food shortages by the 70’s

GMO crops Chemical fertilizers
Major increase in productivity BUT…
Huge profits IMF involvement Pollution- waterways Decline in crop diversity
Energy Technology Oil
Everyone buys a car People like to buy more and more
stuff that needs transportation Oil got big. Really big. Politics in Middle East and Africa Global warming
Nuclear- after the bomb, what else can we use this energy for?
Competition over resources What resources? How does this compare to previous
