“…Each anti-particle has the same mass as its corresponding particle, but the electrical charges are reversed. Examples of antimatter discoveries of the 20th century are: 1) Positrons-Electrons with a positive instead of negative charge; 2) Anti-protons-Protons that have a negative instead of the usual positive charge; 3) Anti-atoms-Pairing together positrons and antiprotons (see [14]). …”

The Special Relativity Theory cannot recognize speed faster than light. New assumption will be imposed that matter has two intrinsic components, 1) mass, and 2) charge, that is M = m + iq. The mass will be measured by real number system and charged by an imaginary unit. This article presents a Complex Matter Space in Relativistic Quantum Mechanics. We are hoping that this approach will help us to present a general view of energy and momentum in Complex Matter Space. The conclusion of this article on Complex Matter Space (CMS) theory will lead help to a better understanding toward the conversion of mass and energy equation, unifying the forces, and unifying relativity and quantum mechanics.

“…David Bartlett has written recently on "Analogies between electricity and gravity" (Bartlett, 2004), providing an historical account and application of analogy. As a historical example, consider Rutherford's planetary model of the atom (Taylor and Zafiratos, 1991). While the original utility was generative -producing a model that explained experimental results (which it accomplished more satisfactorily than competing analogies, such as the "plumb pudding" model of the atom) -the analogy is often used to communicate an introductory atomic model to physics students.…”

This study investigated the effects of analogy on the elimination of students' misconceptions about direct current circuits, students' achievement and the attitudes towards physics lessons. The sample of this study consisted of 51 11th grade students from two different classes. While one of the classes was the experimental group where analogy was used in the lessons, the other class was the control group where the traditional methods are employed in lessons and this selection was made randomly. When the obtained results were examined, it was seen that teaching with analogy has a significantly positive effect on the elimination of misconception and achievement although it has almost no effect on the attitudes of towards physics.Key Words: analogy, teaching, physics education, students, achievement Simply stated, an analogy is a process of identifying similarities between two concepts. The familiar concept is called the analog and the unfamiliar science concept is called the target (Glynn, 1991), Many models have been presented regarding analogy by Brown and Clement (1989), bridging analogies, Dupin and Joshua (1989), the analogy teaching model, Glynn (1991) Teaching-With-Analogy (TWA) and Zeitoun (1984) the general model of analogy teaching. When using an analogy in the teaching of science, teachers should select an appropriate student world analog to assist in explaining the science concept. The analog and target share attributes that allow a relationship to be identified and contribute to the concept being taught; however, there are features of the analogy that are unlike the target, and these can cause impaired learning if incorrectly matched. Consequently, the use of analogies in the teaching of science does not always produce the intended effects, especially when students take the analogy too far and are unable to separate it from the content being learned. Some students only remember the analogy and not the content under study, while others focus on extraneous aspects of the analogy and draw spurious conclusions about the target concept.Analogies are believed to aid student learning by providing visualisation of abstract concepts, by helping compare similarities of the students' real world with the new concepts, and by increasing students' motivation (Duit, 1991). Concrete analogs facilitate understanding of the abstract concept by pointing to similarities between objects or events in the students' world and the phenomenon under discussion. Analogies can be motivational in that, as the teacher uses ideas from the students' real world experience, a sense of intrinsic interest is generated. From a teaching perspective, the use of analogies can enhance conceptual change learning of science as they open new perspectives (Thiele and

“…All materials can be characterized by their tendency to either promote the movement of electrons through their mass, or to inhibit the movement of electrons through their mass; their degree of electrical conductivity (43). Those that promote the movement of electrons are referred to as conductors and those that inhibit the movement of electrons are referred to as insulators.…”

“…As such, electrons will fill the inner most atomic energy levels of an atom first. Each electron occupies a specific atomic orbital, within a specific energy shell, and the further out the energy shell is from the nucleus of the atom the greater the energy attributed to the electrons occupying that shell (47).The highest energy level occupied by an electron, when it is in its non-excited ground state, is the valence shell. Electrons occupying the valence shell are called valence electrons.…”

Laura Christine Sparks DEVELOPMENT AND CHARACTERIZATION OF PHOSPHOLIPID ENCAPSULATED QUANTUM DOT CONSTRUCTS FOR BIOLOGIC APPLICATIONSThe American Cancer Society predicts that 577,190 cancer-related deaths and 1,638,910 newly diagnosed cases of cancer will occur in 2012. As these statistics show, cancer is a prevalent and devastating health issue; determined by the Mayo Clinic to be the second leading cause of death in the United States. Skin cancer is the most common form of cancer in the United States. In 2012 more than 68,000 Americans will be diagnosed with melanoma, 48,000 will be diagnosed with an early form of the disease that has not yet reached the lower levels of the epidermis, and more than 2 million people will be treated for basal cell or squamous cell skin cancer. Early and accurate detection is the most reliable way to ensure a positive outcome and the ultimate survival homodimer-1 stains were applied to determine cell viability, Histochoice was applied as a fixative, and Hoechst staining was employed for cell nuclei identification. Analysis using confocal microscopy suggests successful attachment of QD constructs, in 0.1% w/v keratinocyte media, to the exterior of keratinocyte cell membranes with a 30% average cell survival rate at 24 hours after sample introduction. Future research investigating the interaction of QD constructs with biologic mediums of greater physiological complexity, as well as application of a secondary functionalization, are the next steps on the path toward achieving a viable mechanism for targeting and identifying cancerous cells within a biopsy.vi Acknowledgements
