Ancient Egypt
Ancient Egypt
Ancient Egypt The Old Kingdom which was from about 2755-2255 BC, spanned five centuries of rule by the 3rd through the 6th dynasties. The capital was in the north, at Memphis, and the ruling monarchs held absolute power over a strongly unified government. Religion played an important role, as recorded in Egyptian mythology. In fact, the government had evolved into a theocracy, wherein the pharaohs, as the rulers were called, were both absolute monarchs and, possibly, gods on earth. A Golden Age

Challenger
Challenger It was a cold, crisp, and damp morning on the Florida Space Coast as the space shuttle Challenger raced through the sky at speeds approaching mach 2 at an altitude of 104,000 feet when something went perilously wrong. All of America watched, including the family members of the seven doomed crew members, as Challenger exploded into an expansive ball of fire, smoke and steam. An Oh. . . no! came as the crew’s final utterance from the shuttle as the orbiter broke-up. As the reality of

PYTHAGORAS LIFE
PYTHAGORAS LIFE Most knowledge of Pythagoras and his work comes from his followers, the Pythagoreans. This is because none of his writings survived. Pythagoras was born in 580 BC on the island of Samos. Pythagoras spent his years traveling in search of wisdom and knowledge. He settled in Crotona, a Greek colony in southern Italy. Pythagoras was known as “the father of math and music” by his disciples, the Pythagoreans. They were inspired by his teachings, and they considered him a demigod. The P

Aristotle Aristotle was born in 384 BC and lived until 322 BC. He was a Greek philosopher and scientist, who shares with Plato being considered the most famous of ancient philosophers. He was born at Stagira, in Macedonia, the son of a physician to the royal court. When he was 17, he went to Athens to study at Plato\'s Academy. He stayed for about 20 years, as a student and then as a teacher. When Plato died in 347 BC, Aristotle moved to Assos, a city in Asia Minor, where a friend of his named H

The Universe
The Universe
The Universe It is always a mystery about how the universe began, whether if and when it will end. Astronomers construct hypotheses called cosmological models that try to find the answer. There are two types of models: Big Bang and Steady State. However, through many observational evidences, the Big Bang theory can best explain the creation of the universe. The Big Bang model postulates that about 15 to 20 billion years ago, the universe violently exploded into being, in an event called the Big

NICHOLAS COPERNICUS
NICHOLAS COPERNICUS INTRO- Copernicus was one man who it can be justly said changed the universe- or at least the human population’s perception of it. Copernicus was sometimes honored with the name, Father of Astronomy. He was constantly observing and studying the stars. It is ironic that although he was raised by a prominent catholic bishop that he later presented to the world a new view on the heavens- and the church was not receptive.

Astronomers Part One Brief Descriptions of the Following Astronomers: Walter Baade : Baade was a German-born American, whose work gave new estimates for the age and size of the universe. During the wartime, blackouts aided his observatons and allowed him to indentify and classify stars in a new and useful way, and led him to increase and improve Hubble\'s values for the size and age of the universe (to the great relief of geologists.) He also worked on supernovae and radiostars. Milton Humason :

Ptolemy
Ptolemy Claudius Ptolemaeus, also known as Ptolemy, was a Greek/Egyptian scientist, astronomer, geographer, and mathematician during the second century. Ptolemy made many points throughout his years of studies which were used and relied upon for the next 1300 years. Although some of his theories have been proven incorrect, many others haven\'t and are still used today in mathematics. Born in Egypt and living from about AD 100 to 170, Ptolemy was one of the greatest astronomers and geographers of

Ptolemy Introduction In ancient times there were many great ideas which began to shape the way man perceived his environment. However, there were few minds who were able to put all of these ideas together. One of these minds belonged to Claudius Ptolemy, or just Ptolemy as he is commonly referred to. We know almost nothing of the chronology of Ptolemy\'s life, and we don\'t even know his birth or death dates. We do know, though, about his ideas in several fields, which include geography, astrono

It helps us to develop the co mmunity and society we live in. knowledge shapes the personality of the human being, and the way they deal with problems in their daily routine. Also, it's a huge tool for us to reach our goals and achieve t he dreams we have. As they said when we were kids and growing up Knowledge is power. I t's t

TOK 11 2017 - Safa Azzam SCIENCE VS PSEUDOSCIENCE The application of reason differentiates a scientific theory from pseudoscience.  Reason, as a way of knowing, is the capacity to think beyond immediate experiences. Reasoning is used to build knowledge and to evaluate it. It is closely linked to logic, the deducing of valid conclusions from given starting points or premises. Inductive reasoning supports general statements with statements while deductive reasoning goes from the general to t
