Post Medieval:
1500 to 1950
Story mode.
Five key ideas and takeaways.
1. We start with a story.
From History: 1842.
Subject: Waves.
.
In 1842, Christian Doppler wrote about the doppler effect in stars. It was first confirmed with sound in 1845, then with light in 1848. The big moment came in 1868 when, for the first time, we could tell which stars were coming and going.
When a source moves toward you, waves compress and frequency increases; when it moves away, waves stretch and frequency decreases. This applies to sound (changing pitch), and light (changing color, or redshift).

Subject: Evolution.
- Charles Darwin.
- 1859.
.
Survival belongs to organisms that respond effectively to change as environments shift over time.
Evolution is not about desire, nor is it a contest of strength, or intellect. It’s about reproductive success. The individuals, and species, that possess traits best suited for the current environment are more likely to survive, and to pass on those traits. Over millennia, these traits accumulate, leading to races, sub-species, and eventually separate species unable to interbreed.

Subject: Religion.
.
The first century of the United States was shaped primarily by Protestant culture, Deism, and Enlightenment ideals
At America’s founding, religion was largely Protestant, with strong Enlightenment and Deist influence among the Founding Fathers. Catholics were a small, often mistrusted minority, and modern evangelicalism had not yet emerged. The new republic emphasized religious freedom while deliberately guarding against any single religious group dominating public life.

Subject: The History of Existentialism in 4 Minutes!.
.
Existentialism was born in post medieval Europe, but it’s focus on the self and your own thoughts echos Daoism and Buddhism in the East and Stoicism and Epicureanism in the West.
Modern existentialism has roots going back to the late 1700s and modern psychology has roots back to the late 1800s. Both have deeper roots going back to prehistory. Kierkegaard’s focus on anxiety is part of the story of psychology. Existentialism explores the meaning from a nihilistic view. While it can be fatalistic, modern externalism focuses on living fully and authentically.

Subject: Galileo.
.
In 1610, Galileo Galilei used observation to challenge belief, showing that reality, not tradition, must guide understanding. His telescope turned the heavens from imagined perfection into measurable truth.
In 1610, Galileo published “Starry Messenger.” The original Latin title was Sidereus Nuncius and it is considered one of the most important scientific books ever published, helping to establish the scientific revolution of the 16th and 17th centuries. Galileo, an Italian astronomer, also wrote many of his works in Italian to reach a broader audience, making his discoveries accessible beyond the scholarly elite.
