Claudius Ptolemaeus ( Greek ??a?d??? ?t??eµa??? Klaúdios Ptolemaîos; 90 – 168), known in English as Ptolemy (pronounced /'t?l?m?/), was a Roman citizen of Greek or Egyptian ancestry. [1] He was a mathematician, astronomer, geographer, astrologer and a poet of a single epigram in the Greek Anthology[2][3]. He lived in Egypt under the Roman Empire, and is believed to have been born in the town of Ptolemais Hermiou in the Thebaid. He died in Alexandria around AD 168. [4]Ptolemy was the author of several scientific treatises, three of which would be of continuing importance to later Islamic and European science. The first is the astronomical treatise now known as the Almagest (in Greek, ? ?e???? S??ta???, "The Great Treatise", originally ?a??µat??? S??ta???, "Mathematical Treatise"). The second is the Geography, which is a thorough discussion of the geographic knowledge of the Greco-Roman world. The third is the astrological treatise known in Greek as the Apotelesmatika (?p?te?esµat???), or more commonly in Greek as the Tetrabiblos (?et??ß?ß??? "Four books"), in which he attempted to adapt horoscopic astrology to the Aristotelian natural philosophy of his day. The name Claudius is a Roman nomen; the fact that Ptolemy bore it proves that he was a Roman citizen. It would have suited custom if the first of Ptolemy's family who became a citizen (whether it was he or an ancestor) took the nomen from a Roman called Claudius, who was in some sense responsible for granting citizenship. If, as was not uncommon, this Roman was the emperor, the citizenship would have been granted between AD 41 and 68 (when Claudius, and then Nero, were emperors). The astronomer would also have had a praenomen, which remains unknown. However, it may have been Tiberius, as that praenomen was very common among those whose families had been granted citizenship by these emperors. Beyond his being considered a member of Alexandria's Greek society, few details of Ptolemy's life are known. He wrote in Ancient Greek and is known to have utilised Babylonian astronomical data.[5][6] Although a Roman citizen, most scholars have concluded that ethnically, Ptolemy was a Greek,[7][8][9] while some suggest that he was ethnically an Egyptian, though Hellenized.[8][10][11][12] He was often known in later Arabic sources as "the Upper Egyptian",[13] suggesting that he may have had origins in southern Egypt.[12] Later Arabic astronomers, geographers and physicists referred to him by his name in Arabic ???????? Batlaymus.[14]

1. The Egyptian Queen Cleopatra
October 02, 2009
I guess when a person thinks about Cleopatra the queen of Egypt (51-30 B.C.), what comes to your mind first is her love affairs with Julius Caesar and Mark Antony. When her father who was king of Egypt had died in 51 B.C., Cleopatra, who at the very young age of 17, and her brother, Ptolemy XII, a mere child possibly only 12 years old, both inherited the throne of Egypt, with the understanding that they should marry. However, after a few years had past by, Ptolemy advisors pushed him to gain complete control of the country and to get rid of his sister, Cleopatra. Well, the exiled queen immedia... (read more)

2. "WE DON'T know what we are talking about" - Nobel Laureate David Gross
September 28, 2009
Last December ('05), physicists held the 23rd Solvay Conference in Brussels, Belgium. Amongst the many topics covered in the conference was the subject matter of string theory. This theory combines the apparently irreconcilable domains of quantum physics and relativity. David Gross a Nobel Laureate made some startling statements about the state of physics including: "We don't know what we are talking about" whilst referring to string theory as well as “The state of physics today is like it was when we were mystified by radioactivity.”

3. Demagoguery In Napoleon Hill's Think And Grow Rich
September 11, 2009
Introduction
Thales, Anaximander, Anaximenes, Heraclitus, and Anaxagoras (Ionian philosophers, 6th century B.C.) and other spent their lifetimes searching for a single substance or formula that would explain our changing universe.
Likewise, mathematicians, astronomer, and physicists, such as Euclid, Ptolemy, Pythagoras, Brahe, Kepler, Copernicus, Pascal, Galileo, Descartes, Newton, Leibniz, Einstein, and others searched for constants of the universe by means of mathematical methods-by deductive and inductive reasoning.
Scientists, based on axioms (self-evident truths), build models... (read more)

5. THE WARDINGTON MANOR near BANBURY, OXON
June 26, 2008
Christopher Henry Beaumont Pease, Lord Wardington, of Wardington Manor, near Banbury -- who has died aged 81 -- was a popular member of the village community and an avid collector of maps and atlases. One of his prize purchases was the first illustrated atlas of the world, Ptolemy's Atlas -- published in 1477. Lord Wardington was awarded the Sir Thomas More Medal for Book Collecting in 1994. In April 2004, when a fire destroyed much of the manor house, dozens of villagers formed a human chain to carry his prized collection of books to safety and the building was under re-construction s...

6. The Law of Attraction and The Weird and Wacky World of Metaphysics
March 26, 2008
Quantum science is going beyond the probe of atoms, and exploring the weird and wacky!
New words are entering science, new ideas, theories and dimensions, String Theory, Zero Point Energy Theory, and Membrane Theory to mention a few.
But the weird and wacky isn’t new to science, there has always been controversy and mystery in the science of the very little.
In ancient Greece there was a controversy about the nature of light. Euclid, Ptolemy and others thought that "light" was some sort of ray that travels from the eye to the observed object.
The atomists and Aristotle as... (read more)

Astronomia Vedica - Part II
Cosmological Time Cycles in Indian Astronomy
Long before Copernicus, Galileo & Ptolemy, Aryabhata propounded the Heliocentric Theory of Gravitation, that all planets revolve around the Sun due to celestial gravity. The term given to Celestial Gravity was Guru-tva-Akarshana, which also has a philosophic meaning. Guru represents the Master, the Inner Sun, symbolic of the Self and the planets that revolve represent the students who are on their way to Self_Actualisation !

8. Claudius Ptolemy
December 11, 2006
The astronomer Claudius Ptolemy lived from approximately 100-170 CE. Very little is known of him, including where he was born. Claudius means citizen of Rome, while Ptolemy means resident of Egypt. Some sources indicate that he was a citizen of Rome, others that he lived in Alexandria, Egypt.
He was also a mathematician, geographer and astrologer. In a way, he was to his era what Leonardo da Vinci was to the Renaissance. While many of Claudius Ptolemy’s work has been refuted, his treatises on astronomy, astrology, geography and music were the foundations from which subsequent scientis... (read more)

9. The Invisible Ether and Michelson Morley
March 13, 2006
Modern scientists adopted the ancient concept of the ether to explain the fundamental nature of the universe. Einstein allegedly dethroned the ether concept with his space time continuum. In spite of this, we might have to revisit the ether concept.
The concept of the invisible ether or 'aether' is an old concept dating to the time of the ancient Greeks. They considered the ether as that medium which permeated all of the universe and even believed the ether to be another element. Along with Earth, Wind, Fire and Water Aristotle proposed that the ether should be treated as the fifth el... (read more)

10. Galactic Mystery - Matter - On the Dark Side
March 13, 2006
Scientific inquiry can be described as a sequence of observations leading to a hypothesis which must be tested by experimentation. The results either validate or invalidate the hypothesis which was under test. Unfortunately, the interpretation of the data sometimes does not elucidate some new truth but rather eclipses our thoughts into a new era of ignorance.
Heralding a new age in the cosmos, Norwegian Kristian Birkeland predicted that the universe likely consisted of an exotic component that would later be called dark matter. His comments about this subject matter appeared in a descr... (read more)

11. Big Bang Booming - Back to the Future
February 09, 2006
Theoretical cosmologists spend much of their time perfecting what is now known as the 'Big Bang' theory. This concept originates from ideas percolating in the minds of scientists, theologians and astronomers down through the ages. However, much of what they consider as proof for the 'Big Bang' is dependent upon uncontrolled experimentation that is molded to meet their expectations. Then God said, "Let there be light," and there was light. This ancient description of the creation of the universe found in the Book of Genesis may be accurate after all. The big bang theory describes the b... (read more)

12. "WE DON'T know what we are talking about" - Nobel Laureate David Gross
January 10, 2006
Science has reached an enormous impasse. From biology to physics, astronomy to genetics, the scientific community is reaching the limits of understanding which often presage a complete rethinking of long-accepted theories. So characteristic of this new apex of modern arrogance is the inability to comprehend the obvious in physics: That we don't know what we are talking about.
Last December ('05), physicists held the 23rd Solvay Conference in Brussels, Belgium. Amongst the many topics covered in the conference was the subject matter of string theory. This theory combines the apparently... (read more)

13. The Lighthouse of Alexandria
May 28, 2005
The Lighthouse of Alexandria is one of the Seven Wonders of the Ancient World. It is the most recent Wonder to be built, having been built during the reign of Ptolemy I of Egypt, a commander under Alexander the Great who took over control of Egypt after Alexander's death. Historical records indicate that the Lighthouse was commissioned in 290 B.C. and completed some 2 decades later.
The Lighthouse of Alexandria is also the most well-recorded of the six destroyed members of the Seven Wonders of The Ancient World (the Pyramids of Giza being the only Wonder still standing), since it was still ... (read more)
