air or through a material. Gamma radiation (γ) and electromagnetic radiation, such as x-rays, radio waves heat and visible light are all examples of radiation. One of the main modern physics discoveries was that each unit of a wavelength of any form of wave radiation will carry more energy the shorter it is. Thus, gamma rays and X-rays are especially more energetic than light. These rays penetrate farther into all sorts of matter (UCLA). This essay seeks to discuss and analyse two forms of…

Krueger Murayana the Yirritja Honey Man | Changing of the Guards 1989 | 2012 Natural ochres on wood, feathers, and resin | Lithograph 1990.7008.029 | 2013.4 My Experience at the Fralin Museum The Fralin Museum of Art in Charlottesville wasn’t like any museum I’ve ever gone too. My experience at the Fralin was subpar when compared to my expectations. In such a modest building the rooms had large open ceilings which made the museum feel superior to what it actually was. The Fralin’s…

most important. It is our primary means of understanding the physical nature of our surroundings, both immediate and distant. It is only natural that the great thinkers of antiquity were curious about the nature of vision, and inseparably, that of light itself. In the manner characteristic of ancient science, many common ideas about optics were “hit or miss”, so to speak. Certain Greek thinkers had hypotheses about optics which are more or less in line with modern principles, but many held…

affect the final outcome of any piece of work. Theses conclusion I came to understand, made my experience in the Dallas Museum unique and exceptional. However, the feeling of entering the museum was completely different than what I visualized in mind before going there. At the moment I entered the museum and walked through the hallway, I came across wonderful paintings and art. However, there was one that grabbed my attention…

The premise of light and darkness is illustrated, questioned, and rationalized throughout the novella. “Annette Seated” expresses these major themes of Heart of Darkness in a visual, concrete representation. This painting communicates the insufferable oppression of colonization…

The visible pulse (gating pulse) enters the microscope, and together with the ultrafast electron pulses illuminate the nanostructure specimen (gold nanoparticle). The visible laser pulse kept at low power (~1.8 mJ/cm2) to avoid saturation. At the spatiotemporal overlapping, the coupling between the visible and electron pulses takes place. The signature of this coupling can be revealed by measuring the electron energy spectrum using the electron energy spectrometer attached to the microscope. The…

4.0 Results and Discussion Before the strontium quantification of the solutions resulted from the ion exchange experiments, it was necessary to investigate what is the range where strontium absorbs radiation linearly and what is the detection limit. The graphs below show the absorbance (atomic absorption) in function of the strontium concentration and it can clearly be seen in figure 2 that at concentrations above 10 ppm the samples start to present non-linear absorption. Therefore, all the…

is the light. When a beautiful colorful butterfly gets you attention and put a smile on your face, you would not be able to enjoy this scene without light. When a famous paint in a museum let your jaw drops in amazement, you must know that light is the medium that convey the beauty of the paint to your eyes. Let us not go too far, you would not be able to read these very words without the blessing of the light. Moreover, light plays an important role on people feelings and emotions. Light can…
