7/12/10 This week's research on fission and fusion helped me to understand that fission, according to the Einstein Relationship, can yield high amounts of energy due to break-up of atoms such as, Uranium. Fusion, on the other hand, yields large amounts of energy as a result of combining light nuclei.
7/12/10 This week's multiple hours of research on nuclear radiation also led to an understanding that an atom of a radioactive isotope will spontaneously decay into another element through alpha decay, the loss of an alpha particle, beta decay, the loss of a beta electron and an antineutrino, or a gamma ray.
6/30/10 In researching the Lens Maker’s Equation I learned that this equation is used to determine if a lens will behave like a converging (convex) lens, having a positive focal length, or a diverging (concave) lens, having a negative focal length, by relating the focal length of a simple lens with the spherical curvature of its two faces.
7/1/10 After a couple of hours experimenting with the ray simulation model and researching Lens Maker's Equation, I discovered that a lens refracts lights in order that the rays will come together at a point, produce an image, and move in parallel lines.
6/29/10 In my several hours of research in preparation for project two, constructing a refracting telescope, I learned electromagnetic waves are produced by the motion of electrically charged particles.
7/2/10 In the many hours I spent researching, collecting supplies, and constructing in order to complete project 2, I realized that the image seen when looking through a telescope, is created inside the focal length of the eyepiece, which allows for a magnified, virtual image the eye is able to see.
7/6/ 10 After exploring the Physics 2000 website for several hours, I was reminded of various concepts with regards to decay. I didn’t remember that when nuclei split, radiation is the product. I also remembered that beta decay is the loss of an electron, alpha decay is the loss of 2 protons and 2 neutrons, and gamma ray are produced by the loss of a photon.
6/1/10 Participated in reflective discussion on a Wiki based upon viewing YouTube videos, "A Vision of Students Today" and "Shift Happens"
6/2/10 Created biography glog and animoto video
6/3/10 Observed and commented on various videos, participated in Wiki discussions on the nature of science, and engaged in email conversations on electricity concepts
6/17/10 Through the construction of a multimedia technological glog for project one, I was able to demonstrate the data I collected from my coil gun experiments, researched information on the physics behind the flash of a camera, and reflections on things that didn't go as hoped for throughout the course of project.
6/23/10 Through nearly five hours of research and writing, I have compiled three paragraphs in support of the 2012 theory and three paragraphs in opposition to the theory, which I have posted on the class wiki.
6/22/10 I participated in a thirty minute Skype interview with David in order to discuss questions I had in regards to assignments from the first three weeks of class.
7/8/10 After nearly five hours of research and composing, I completed my additions to the second controversy wiki on global warming. I learned that there actually are two scientifically supported sides to the theory of global warming.
7/11/10 Through organized, well prepared communication I interviewed a dentist on his use of the Cadent iTero digital imaging system, in preparation for the completion of project 3.
7/20/10 Through both oral and written communication, I constructed a comprehensive video chronicling projects completed and lessons learned throughout the course of Physics 112, as a final interview project.

6/7/10 By listening to the pentcast and performing the sticky tape experiment, I explored and grasped foundational concepts in electricity, charges, forces, and fields.
6/17/10 Lenz's Law explains the reason movement of metal across a magnet slows the metal's movement. It is the result of an induced electric current, which acts as a break on the metal object.
6/24/10 After both Skyping and listening to the Screencast, I understand the application of Lenz's Law in regards to the flash coil gun. As a result of a change in a magnetic field in the presence of a conductor, a voltage is produced in the conductor that causes a current to flow in that conductor, which in turn causes a magnetic field in that conductor, that opposes the charge.
7/7/10 In my exploration of the Physics 2000 website, some EMR principles became more clearly understood. For instance, electromagnetic radiation can travel through empty space, unlike other types of waves. In addition, I understand that a force field is a way to picture the effects that electric charges have on one another. I also realized that each element has its own unique spectral signature (created by electrons jumping from one energy level to another).
7/13/10 This week's exploration of nuclear physics began with contrasting atomic physics, which focuses mainly on the properties of atoms due to their electron configurations, versus nuclear physics, which focuses upon the construction and reactions involving the nucleus.
