Human history is often framed as a series of episodes, representing sudden bursts of knowledge. The Agricultural Revolution, the Renaissance, and the Industrial Revolution are a few examples where it is generally thought that innovation moved quicker than at other points in history, leading to a shake-up in science, literature, technology, and philosophy.
The Scientific Revolution is the most notable of these, emerging just after the dark ages.

Much of the knowledge about the natural world during the middle ages dates back to the teachings of the Greeks and Romans. Many did not question these ideas, despite the many flaws.
The man who started the scientific revolution was a Renaissance mathematician and astronomer, Nicolaus Copernicus.
Copernicus developed a heliocentric alternative to Ptolemy's planetary system. His system placed the Sun at the center instead of the Earth. The detailed controversial theory of Copernicus enraged the Catholic church, and was eventually banned in 1616.
Several decades later, the English mathematician Isaac Newton proved the Copernican heliocentric model. Newton's discoveries in many ways marked the end of the Scientific Revolution. His achievements became the foundation for modern physics.
In 1687, Newton described three laws of motion to help explain the mechanics behind elliptical planetary orbits. He also made several other significant contributions to the field of optics.
After the heliocentric model was banned, Johannes Kepler, a German mathematician, developed a keen interest and later published a public defense of Copernicus' theories.
Corpernicus' model still had flaws in predicting planetary motion. Kepler theorized that planetary bodies orbit along an elliptical path, and not perfect circles as Ptolemy and Copernicus had assumed.
Kepler also made other notable discoveries.
Galileo Galilei, a contemporary of Kepler, built a telescope and began fixing its lens on the planets. He made a series of remarkable discoveries: that the moon was not flat and smooth, there were spots on the sun, Jupiter had moons that orbited it, Venus had phases like the moon, which proved that the planet rotated around the sun.
Galileo published his findings but was later put on trial for heresy and put under house arrest for the remainder of his life. He never stopped his research and published several theories until his death in 1642.
The assumption that the Earth can stop spinning is far-fetched. But, what if something changed the Earth's rotation? Let's assume the Earth stopped spinning gradually.
And let's suppose that Earth's ecosystems have survived the transition. What would the new world look like?
In the Histories by Herodotus (484BC to 425BC), Herodotus recounts the story of Phoenician sailors who were dispatched by King Neco II ofEgypt (about 600BC), to sail clockwise around continental Africa, starting in the Red Sea.
The voyage took years. As they rounded the southern tip of Africa, and following a westerly course, the sailors observed the Sun as being on their right-hand side, above the northern horizon. Because they still thought the Earth was flat, the observation did not make sense at the time.
