Geocentric vs Heliocentric Model of the Universe
Learn how a geocentric view of the universe is different than a heliocentric model of the universe.
The geocentric view, which has the Earth at the center of the Universe was accepted for many years. However, it could not explain the backward movement of some planets.
The sun-centered view of the universe was proposed by Copernicus and later modified by Kepler and other great minds.

Geocentric model: planets orbiting the Earth 🌍
Our ancestors used this model as the basis for astronomical charts. Of course, now we know that the Earth and other planets revolve around the Sun, and the model in the video is nothing more than a beautiful pattern.

Ancient humans really wanted Earth to be the center of the universe. Geocentrism wasn't a mistake. Ptolemy wasn't that far off from the truth. He just gave Earth too much importance.

What Is The Ptolemaic System? (Geocentric Model)
Ptolemy is recognized as putting the final additions to a solar system model which had been slowly created in Ancient Greece for over 600 years. The Golden Age of astronomy consisted of multiple philosophers, mathematicians and astronomers all adding to a geocentric model to explain how place in the universe and how it functions through their observations. This video discusses the development of this model culminating in Ptolemy's contribution and the church's seal of approval.

The Ptolemaic Dynasty of Ancient Egypt: From Ptolemy I to Cleopatra VII
The Ptolemaic dynasty in Ancient Egypt began under the rule of Ptolemy I Soter, whose goal was to make Egypt great again and he did that by putting the country back on solid economic and administrative footing, and it ended with Cleopatra VII. When Alexander the Great of Macedon died unexpectedly in 323 BCE he had amassed an enormous empire spanning from Egypt through Anatolia, Mesopotamia and parts of India. In order to stay away from the influence of the priests and officials at Memphis, Ptolemy I moved the capital from its traditional place at Memphis to Alexandria. Alexandria, a city established by Alexander the Great, grew and flourished under the Ptolemies. The city became more of a Greek city than an Egyptian one, with the port giving easy access to the sea and Greece, and with Gree...

Ptolemy's Geocentric Model
Without modern instruments, it was very hard to understand what the planets were, especially since they seemed to wander independently from the stars. Ptolemy provided the definitive answer for the time being. Earth was the centre of the universe and all the heavenly bodies rotated around it.
For inquiry, consider the following:
1. Investigate the work of Aristarchus. What was his model of the universe and why? How did it differ from Ptolemy's?
2. Why is there no gale force wind blowing constantly as the Earth moves about the Sun? What is the cause of wind? How do hurricanes evolve?
3. What was it about the Ptolemaic model that allowed it to last for 1500 years, and what was it that eventually brought about it's demise?
4. Explain why you don't change position in a moving train when you j...

Ptolemy’s Theorem and the Almagest: we just found the best visual proof in 2000 years
We are making history again by presenting a new visual proof of the 2000+ years old Ptolemy's theorem and Ptolemy's inequality.
00:00 Introduction
04:27 Geometry 101
08:19 Applications
14:46 Ptolemy's inequality
18:34 LIES
25:35 Animated proofs
28:57 Thank you!
30:53 Degenerate Easter Egg
There are some other proofs of Ptolemy's theorem/inequality based on scaling and aligning suitable triangles. However, none of them is as slick, beautiful and powerful as Rainer's new proof. In particular, check out the animated scaling proof on the wiki page for Ptolemy's theorem (and this https://youtu.be/ZK08Z5A9xH4) and check out the scaling proof by Claudi Asina and Roger Nelson: Proof Without Words: Ptolemy’s Inequality in Mathematics Magazine 87, (2014), p. 291. https://www.jstor.org/stable/10.4...

033: Ptolemaic Egypt - Ptolemy I: Son of Lagus, Son of Ra
Ptolemy I Soter, a former commander of Alexander the Great turned King and Pharaoh of Egypt, was perhaps the craftiest out of all of Alexander’s Successors. A talented commander and even more brilliant politician, Ptolemy would wield diplomacy and intrigue with a deft hand, founding what would become the longest lasting Hellenistic Kingdom in his nearly 40-year reign.

Alexander the Great of Macedon died unexpectedly in 323 BCE he had amassed an enormous empire spanning from Egypt through Anatolia, Mesopotamia and parts of India.

Alexandria, a city established by Alexander the Great, grew and flourished under the Ptolemies. The city became more of a Greek city than an Egyptian one, with the port giving easy access to the sea and Greece, and with Greece becoming the language of both commerce and government.
A thing to note about the Ptolemies, although they were Pharaohs of Egypt, they didn’t learn the Egyptian language and pretty much just stayed in Alexandria (which they had made the new capital, moving it from the traditional capital of Memphis). They used Greek for all of their administrative documents, and married within their own family to keep the bloodline pure and also keep their wealth in the family.

Without modern instruments, it was very hard to understand what the planets were, especially since they seemed to wander independently from the stars. Ptolemy provided the definitive answer for the time being. Earth was the centre of the universe and all the heavenly bodies rotated around it.
For inquiry, consider the following:
1. Investigate the work of Aristarchus. What was his model of the universe and why? How did it differ from Ptolemy's?
2. Why is there no gale force wind blowing constantly as the Earth moves about the Sun? What is the cause of wind? How do hurricanes evolve?
3. What was it about the Ptolemaic model that allowed it to last for 1500 years, and what was it that eventually brought about it's demise?
4. Explain why you don't change position in a moving train when you jump up in the air. Why does the train not move out from under you?
5. Use this website as a starting point to do some research and reporting into the great minds that have influenced our understanding of the heavens: https://starchild.gsfc.nasa.gov/docs/StarChild/universe_level2/cosmology.html
6. In Western society, we often hear only about the Greeks and perhaps the Egyptians, with regard to astronomy. Find one major astronomical contribution made by the Chinese, the Indian and at least one First Nation.

There are some other proofs of Ptolemy's theorem/inequality based on scaling and aligning suitable triangles. However, none of them is as slick, beautiful and powerful as Rainer's new proof. In particular, check out the animated scaling proof on the wiki page for Ptolemy's theorem (and this https://youtu.be/ZK08Z5A9xH4) and check out the scaling proof by Claudi Asina and Roger Nelson: Proof Without Words: Ptolemy’s Inequality in Mathematics Magazine 87, (2014), p. 291. https://www.jstor.org/stable/10.4169/math.mag.87.4.291
Rainer was inspired by a classic scaling based proof of Pythagoras theorem that I presented here https://youtu.be/p-0SOWbzUYI?si=GeGzZ0R_Dj1AsXqR&t=371
You can find a couple of full text versions of the Almagest here

There are very interesting higher-dimensional versions of Ptolemy's theorem just like there are higher-dimensional versions of Pythagoras theorem. I did not get around to talking them today. Google ...

Ptolemy's theorem made a guest appearance in the the previous Mathologer video on the golden ratio: https://youtu.be/cCXRUHUgvLI
Here is a nice trick to make Ptolemy counterparts of Pythagorean triples. Take any two sets of Pythagorean triples:
5² = 3² + 4², 13² = 12² + 5², and combine them like this:
65² = 13² × 5²= 13²(4² + 3²) = 52² + 39²= 5²(12² + 5²) = 60² + 25².
Now combining the two right angled triangles 52-39-65 and 25-60-65 along the common diagonal in any of four different ways gives a convex quadrilateral with all sides integers. Note that you automatically get 5 integer lengths and then Ptolemy's theorem guarantees that the remaining side is a fraction. Scaling up everything by the denominator of that fraction gives one of the special integer-everywhere quadrilaterals. See also Brahmagupta quadrilaterals.
Here is a nice application of Ptolemy's theorem to a International Maths Olympiad problem https://www.youtube.com/watch?v=NHjtHOE1lks
In a cyclic quadrilateral the ratio of the diagonals equals the ratio of the sums of products of the sides that share the diagonals' end points: https://www.geogebra.org/m/XQr5jJQg This extension of Ptolemy's theorem is part of the thumbnail for this video.

Ptolemy I Soter, a former commander of
Alexander the Great turned King and Pharaoh of Egypt, was perhaps the craftiest out of all of Alexander’s Successors. A talented commander and even more brilliant politician, Ptolemy would wield diplomacy and intrigue with a deft hand, founding what would become the longest lasting Hellenistic Kingdom in his nearly 40-year reign.
