What is the evidence for the existence of dark matter in galaxies and in the Universe? Since early 1930s physicists attempted to understand and solve the “missing mass problem” in the galaxy and universe. This missing mass problem has spurred on astronomers and particle physicists on a quest to gain greater understanding of the universe. One of the key postulations to solve this missing mass problem is dark matter. Scientist has continually conducted experiments attempting to provide evidence

EOSC 114 – Final Review Notes Get A’s or die trying. Jason Kim Unit 1: A Fragile System At least 3 earthquake recording stations are required to find the location of the earthquake epicenter. A single recording station can only calculate distance‚ but not direction; to cover all possibilities‚ a complete circle is drawn around that station. If only two earthquake recording stations are used‚ the circles will overlap at two points. Data from a third recording station will eliminate one of

In Art 114 we were given a research assignment in which we analyzed art by taking both a formal and contextual approach. This project was intended to use the concepts learned in class and applying it contemporary art‚ our own artwork‚ or architecture. Each student could choose from four different topics such as: a video lecture‚ making art‚ research paper‚ or a group gallery show project. I will explain my personal experience of the research project as well as a critique of two best research projects

Electrical Components and Circuits Course: PHY101 Purpose: The purpose and objectives of this lab was to be able to draw completed electrical circuits using the correct symbols for selected electrical components‚ including batteries and diodes. Another focus was to calculate the proper resistance using Ohm’s law‚ use proper electrical currents and quantities‚ and lastly measure voltage and resistance in an electrical circuit using a multimeter.

Cutting the Kiowa Down Removal of the OH-58D(R) Kiowa The government decision to remove the OH-58d(R) Kiowa Warrior from its inventory is hasty. Their quick decision to remove certain aircraft and fill in slots with other does not seem logical. The Army is also changing its inventory by playing a poorly planned game of leap frog with the AH-64 Apache and the UH-60 Blackhawk moving them between Active and the National Guard. The overall plan is to make the Apache the primary and only
