General relativity

Albert Einstein’s Change of Heart: From Pacifism to the Atomic Bomb Beyond doubt, Albert Einstein is one of the most famous scientists of the 20th century. His name is the first one that comes to mind when one looks for genius. This is not without reason since we owe him most of what we know about space and time. Even though he usually appears with his smiling face, fluffy white hair and pipe in his photographs, when one looks deep into his eyes, it is striking to sense some sort of sorrow…

The great Neil deGrasse Tyson once said something along the lines of humans have only discovered about 4% of the universe. Not only does my fear of what I don't know going on below my feet in the ocean scare the crap out of me, but that big star filled sky does as well. It doesn't just scare me, but it probably scares and excites scientists studying it all over the world. Since we only know a fraction of the inter-workings of the universe, there are many questions and things going on that we…

contributing factor into why dark matter and dark energy aren’t understood is because dark energy is not derived from matter or radiation. Even though dark matter and energy are linked, dark energy does not come from dark matter. The theory of general relativity cannot explain dark energy because it can not be applied to particles as small as atoms which is another reason why dark energy is not fully…

Big History has produced many themes within in context, with the most prominent being complexity. However, expansion can also be seen as the most important theme that traverses through the Big History story. Expansion can be seen in at the very beginning with the Big Bang, through the increasing expanding universe that we live in today, it can also be seen in the creation and development of our stars and planets. Furthermore, expansion allows for the many diverse and different organism alive on…

know about the state of the universe today we can demonstrate that the universe must have began with a singularity(a microscopic point of infinite mass and infinite energy).This is know this because of the predictions made by Einstein’s General Theory of Relativity about our universe; our universe is expanding like a balloon you could say, this is demonstrable because…

In this experiment the main goal is to examine the correlation between position, velocity, time, and acceleration of objects, moving in one or two dimensions. Each and every experiment will be conducted under different conditions. For example, the first experiment requires a constant force (gravity) to act on the object, the picket fence. This experiments other condition is that we neglect friction. This object should be in nearly ideally circumstances. In the second experiment, the conditions…

Within “Frost at Midnight,” Samuel Coleridge validates the importance of self-reflection through solitude. Coleridge creates a scenic image of the world around the speaker during the time of his solitude. During his time alone, the speaker reflects about his childhood and the aspiration he has for the infant child sleeping in the cottage. The importance of solitude demonstrated in “Frost at Midnight” by the feelings the speaker has, the time intervals from present to past, and the speaker’s…

The key general capabilities necessary to rebalance the Joint Force 2025 given the current strategic direction and global security environment to ensure Freedom of Maneuver (FOM) in the global commons and dominance within the cyber and space domains. Enhanced capabilities to protect cyber and space domains and synchronized partnered alliances are required to counter threats to these domains. This rebalancing is warranted to maintain a level of readiness that meets the needs of the National…

For over 55 years, humans have been flying in space. With an understanding of evolution, it has always been assumed that human bodies have adapted to the gravitational force found here on Earth. The space station and the shuttle that most NASA astronauts will stay in orbits 350 km above Earth, with a gravitational pull 90% stronger than it is on the ground (NASA Space Bones). Giancoli describes objects orbiting the Earth as feeling weightless because they are, in essence, free falling towards…

According John Gaddis in “The Landscape of History” he explores the question of “What do historians do?”, along with the various ways in which they conduct their research to ultimately document history. In comparison to Mary Jo Maynes and Ann Waltner’s book “The Family: A World History” they approach history from the perspective of the family. Maynes and Waltner explore the history of the family and its influence on religion and politics. Though both books explore contrasting arguments, we can…
