Analemma
In astronomy, an analemma (/ˌænəˈlɛmə/; from Greek ἀνάλημμα "support") is a diagram showing the deviation of the Sun from its mean motion in the sky, as viewed from a fixed location on the Earth. Due to the Earth's axial tilt and orbital eccentricity, the Sun will not be in the same position in the sky at the same time every day. The north–south component of the analemma is the Sun's declination, and the east–west component is the equation of time. This diagram has the form of a slender figure-eight, and can often be found on globes of the Earth.
Diagrams of analemmas frequently carry marks that show the position of the Sun at various closely spaced dates throughout the year. Analemmas with date marks can be used for various practical purposes. Without date marks, they are of little use, except as decoration.
Analemmas (as they are known today) have been used in conjunction with sundials since the 18th century to convert between apparent and mean solar time. Prior to this, the term referred to any tool or method used in the construction of sundials.

Ptolemy
Claudius Ptolemy (/ˈtɒləmi/; Greek: Κλαύδιος Πτολεμαῖος, Klaúdios Ptolemaîos, [kláwdios ptolɛmɛ́ːos]; Latin: Claudius Ptolemaeus; c. AD 100 – c. 170) was a Greco-Egyptian writer, known as a mathematician, astronomer, geographer, astrologer, and poet of a single epigram in the Greek Anthology. He lived in the city of Alexandria in the Roman province of Egypt, wrote in Koine Greek, and held Roman citizenship. Beyond that, few reliable details of his life are known. His birthplace has been given as Ptolemais Hermiou in the Thebaid in an uncorroborated statement by the 14th-century astronomer Theodore Meliteniotes. This is a very late attestation, however, and there is no other reason to suppose that he ever lived anywhere else than Alexandria, where he died around AD 168.
Ptolemy was the author of several scientific treatises, three of which were of continuing importance to later Byzantine, Islamic and European science. The first is the astronomical treatise now known as the Almagest, although it was originally entitled the "Mathematical Treatise" (Μαθηματικὴ Σύνταξις, Mathēmatikē Syntaxis) and then known as the "Great Treatise" (Ἡ Μεγάλη Σύνταξις, Ē Megálē Syntaxis). The second is the Geography, which is a thorough discussion of the geographic knowledge of the Greco-Roman world. This manuscript was used by Christopher Columbus as the map for his westward-bound path to Asia, in which he discovered the hitherto unknown lands of the Americas. The third is the astrological treatise in which he attempted to adapt horoscopic astrology to the Aristotelian natural philosophy of his day. This is sometimes known as the Apotelesmatika (Ἀποτελεσματικά) but more commonly known as the Tetrabiblos from the Greek (Τετράβιβλος) meaning "Four Books" or by the Latin Quadripartitum.

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 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.

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

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.

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 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.

Analemma
In astronomy, an analemma (/ˌænəˈlɛmə/; from Greek ἀνάλημμα "support") is a diagram showing the deviation of the Sun from its mean motion in the sky, as viewed from a fixed location on the Earth. Due to the Earth's axial tilt and orbital eccentricity, the Sun will not be in the same position in the sky at the same time every day. The north–south component of the analemma is the Sun's declination, and the east–west component is the equation of time. This diagram has the form of a slender figure-eight, and can often be found on globes of the Earth.
Diagrams of analemmas frequently carry marks that show the position of the Sun at various closely spaced dates throughout the year. Analemmas with date marks can be used for various practical purposes. Without date marks, they are of little use, except as decoration.
Analemmas (as they are known today) have been used in conjunction with sundials since the 18th century to convert between apparent and mean solar time. Prior to this, the term referred to any tool or method used in the construction of sundials.
