How old was ptolemy XIV when he died?

Ptolemy XIV was about 11 or 12 when he mysteriously died.

How did the maps drawn by ptolemy and al'ldrisi revolutionize European sea exploration?

Maps drawn by Ptolemy and Al-Idrisi improved navigational accuracy and provided detailed information on coastlines, ports, and landmarks, which were essential for European sea exploration. These maps helped to expand European knowledge of the world's geography and enabled explorers to plan and execute their voyages more effectively. The detailed and precise mapping of new territories opened up opportunities for trade, colonization, and the exchange of ideas between Europe and other regions.

What is the name of egyptians immortal drink?

The ancient Egyptians believed that the gods drank wine, just as mortals drank wine. There was even a goddess of wine (Renenutet). Offerings made every day to the statues of the gods included large quantities of wine.

The idea of an "immortal drink" is completely false and typical of fake facts being distributed by young people on different internet forums.

Who developed ideas that contradicted Ptolemy's geocintric modil of the univerise?

One of the most notable figures who developed ideas contradicting Ptolemy's geocentric model of the universe was Copernicus, who proposed a heliocentric model with the Sun at the center. Copernicus's work laid the foundation for later scientific revolutions in astronomy led by Galileo, Kepler, and others.

Where is Ptolemy I buried?

Ptolemy I was buried in Alexandria, Egypt. His final resting place is believed to be in the royal necropolis at the ancient city of Alexandria, although the exact location of his tomb has never been confirmed.

What was the most powerful man in Egypt?

The most powerful man in ancient Egypt was typically the pharaoh, who was considered both a political and religious leader. The pharaoh had absolute power over the land and its people, with control over military, administration, and religious practices.

Did ptolemy have any siblings?

Yes, Ptolemy had siblings. He was a member of the Ptolemaic dynasty of Egypt, and his siblings included his brother, who was his predecessor on the throne, and his sister, who was also his wife.

Does cloepatra have a trade mark?

No, Cleopatra, the ancient Egyptian queen, does not have a trademark as trademarks are used in modern times for branding and protection of intellectual property. Cleopatra lived before the concept of trademarks existed.

Explanation of Ptolemy's Theorem?

If a quadrilateral has its vertices on a common circle, then if you multiply the digonals, it should come out the same as if you take one pair of opposite sides, multiply their lengths, do the same for the next pair, and then add them together.

Why did the existence of stellar parallax not convince people in Copernicus time that his model was better than Ptolemys geopcentric model?

In Copernicus's time, the lack of perceived stellar parallax was not considered strong evidence because people believed that the stars were too distant for their motion to be detected. Additionally, many were entrenched in the geocentric model due to longstanding tradition, religious beliefs, and lack of understanding of heliocentric principles. It took further advancements in observational technology and understanding of astronomy for the heliocentric model to gain widespread acceptance.

How many planets did ptolemy discover?

Ptolemy did not discover any planets. He lived in the 2nd century AD and his work primarily focused on developing mathematical models to explain the motion of the planets as observed from Earth. The discovery of the planets we now know was made by astronomers in different time periods.

What was ptolemy's childhood like?

Not much is known about Ptolemy's childhood, as historical records are limited. He was born in Egypt around 90 AD and came from a wealthy and influential family. It is believed that he received a well-rounded education, possibly including training in mathematics and astronomy that would later influence his work as a scientist.

Did Galileo find it impossible to believe that the earth was the center of the universe?

Yes, Galileo rejected the notion of geocentrism and instead supported the heliocentric model proposed by Copernicus. Galileo's observations through his telescope provided evidence that supported a sun-centered solar system.

When was latitude and longitude invented by Hipparchus and Ptolemy?

Latitude and longitude as a coordinate system were developed separately by Hipparchus and Ptolemy in the 2nd century BC. They both contributed significantly to the mapping and understanding of the Earth's surface, with Hipparchus focusing on latitude and Ptolemy introducing the concept of longitude.

How did Ptolemy's works affect mapmaking in the 1400s?

Ptolemy's works, specifically his Geographia, had a significant impact on mapmaking in the 1400s by emphasizing the use of latitude and longitude lines, leading to greater accuracy in mapping. His maps provided a framework for cartographers to accurately depict the world and navigate more efficiently, which contributed to the Age of Exploration in the 15th century.

How did the maps drawn by ptolemy and al-idrisi revolutionize European sea exploration?

The maps drawn by Ptolemy and al-Idrisi revolutionized European sea exploration by providing more accurate and detailed geographic information, such as coastlines, distances, and landmarks. This enabled European explorers to plan their journeys more effectively and navigate unknown waters with greater confidence. The maps also helped expand European knowledge of the world, leading to increased exploration and trade.

The ancient Greek geographer Ptolemy created a grid system and listed the for places throughout the known world in his book Geography?

Yes, Ptolemy's Geography book was a comprehensive work that combined mathematical principles with geographical knowledge. It included a grid system of longitude and latitude and provided coordinates for over 8,000 locations. This system of mapping influenced cartography for centuries to come.

What territory did Ptolemy get after the death of Alexander the Great?

After the death of Alexander the Great, Ptolemy gained control of Egypt and established the Ptolemaic Kingdom. He founded a dynasty that ruled Egypt for nearly three centuries, until it fell to the Romans in 30 BC.

Who was the last ruler of the ptolemy dynasty?

The last ruler of the Ptolemaic dynasty was Cleopatra VII. She was the last pharaoh of Ancient Egypt, ruling jointly with her son, Ptolemy XV Caesarion. After the defeat of her forces by Octavian, Cleopatra committed suicide in 30 BCE.

Who was the last dynasty ruler of the ptolemies?

That depends on who you ask.

The last actual Pharaoh of Egypt was a shared throne between Cleopatra VII and her son Ptolemy XV, from 44 to 30 BCE After the death of Cleopatra, Egypt became a Roman province, ruled by the Emperor of Rome.

In some cases, the Roman Emperor was also titled Pharaoh of Egypt, specifically while he was in Egypt. There is at least one Egyptian list of kings which lists the Emperors of Rome as Pharaohs for another 280 years, ending with Decius, who was Emperor from 249 to 251, CE.

But, the most common answer would be Cleopatra.

On this day in 1633 what Italian physicist was put on trial for saying Earth was not at the Universe's center?

Galileo Galilei was the Italian physicist put on trial in 1633 for supporting the heliocentric model of the solar system proposed by Copernicus, which stated that the Earth revolved around the sun. This was considered heretical by the Catholic Church at the time.

Why did people believe that a geocentric system was correct?

The geocentric system is very plausible to people who have not looked deeply into the subject of astronomy, because at first glance, that's how things appear. We stand on a world that does not feel like it is moving. Our senses tell us that it is motionless (not counting earthquakes). It is somewhat difficult to imagine that this vast, seemingly motionless surface that we are standing on is actually moving through space. And when we look at the sky, we see various astronomical objects which rise and set, just as if they were circling the motionless Earth.

When did Cleopatra marry Ptolemy xiv?

Cleopatra married Ptolemy XIV, right after the death of Prolemy XIII under orders from Caesar.
