Around the turn of the 17th century, John Donne was at the beginning of a seemingly successful political career as the secretary to the Lord Keeper of the Great Seal, Thomas Egerton. His ambitions were scuppered, however, when he eloped with Egerton’s seventeen year old niece in 1601 (Norton 1371). Donne was immediately fired, and relegated to relative poverty in the country. The political world that he had been a part of was now abruptly and resolutely closed to him. Although his love poem “The

Ever since the beginning of time there have been stars. Not only stars in the sky, but moons, planets, and even galaxies! Astronomy is defined as the branch of science that deals with celestial objects, space, and the physical universe as a whole. In other words it is the study of space, planets, and stars. Throughout the ages, many people have used astronomy to help them learn about the universe, our own planet, and even make predictions about life itself. Understanding astronomy means understanding

“Synesius, you don’t question what you believe, or cannot. I must.” – Hypatia The historical film Agora focuses on a lot of points such as, politics, social status, gender equality, religion and astronomical views. The story revolves around one of the most glorified women in ancient Alexandria, the mathematician/philosopher/astronomer, Hypatia. She is first seen lecturing to her students about how things on Earth tend to fall down in a straight path downward. She demonstrates this idea by dropping

Johannes Kepler was a German astronomer and mathematician who lived between 1671-1630. Kepler was a Copernican and initially believed that planets should follow perfectly circular orbits (“Johan Kepler” 1). During this time period, Ptolemy’s geocentric theory of the solar system was accepted. Ptolemy’s theory stated that Earth is at the center of the universe and stationary; closest to Earth is the Moon, and beyond it, expanding towards the outside, are Mercury, Venus, and the Sun in a straight line

Restrictions on freedom will inevitably lead to conflict| Rosie Liberow As a young child, I always wanted to be bigger, older and wiser. I dreamed of being in high school, or being a perfect well dressed secretary working in an office. Yet they say time flies when you’re having fun, but it seems now that I yearn for those times again, those boundaries and limitations. Freedom is daunting; the world is big and dangerous and I often find myself wishing I was young again. For me, the liberty I do have

extends past the beginning of humankind and the following philosophers, mathematicians, and astronomers will attempt to provide explanations of what is known today as the Great Unknown. The universe of the past was understood to be a simple one-galaxy model that was both unchanging and immeasurable. Theories have constantly changed and been reconstructed to better portray the progression of human understanding over time. “The cosmos began

For years the Earth was thought to be flat. The groups of people that created and developed this theory were heavily influenced by religion and cultural practices that were prominent at the time. The theory was a way to explain the Earth and it made sense in the explanations people could create. After many years of scientific exploration and technological development this theory was disproven. The new theory was that Earth is a sphere. However, even after the observations of a spherical Earth the

Ancient Greek Astronomy Imagine if the ancient world didn’t make any discoveries and the people of today had to start without any prior knowledge. In about 500BC the ancient Greeks had an explosion of astronomical discoveries. The ancient Greeks wanted to know the answer to one big question; how does the universe work? The ancient Greeks contributed to astronomy through the discoveries about Earth, the universe, and the tools they used. The ancient Greeks contributed to astronomy through their

establish an understanding about mental models created by children and discover how these concepts change in association with age and gender. According to Vosniadou and Brewer (1992), mental models are dynamic in nature, generated by children in response to questions asked and used to detect their perceptions of the earth. Mental models are categorized to be naïve, synthetic or scientific. Naïve models are believed to be an outcome of everyday experience; synthetic models to be formed to deal with the irregularity
