Light Years

Borealis? As electrically charged particle collisions from the sun enter the planet’s atmosphere and encounter atmospheric gases, a light show spectacle is displayed around the magnetic poles of the earth. The aurora phenomenon occurs at poles of both the northern and southern hemispheres of the planet. They are most commonly known as the “Northern Lights” and “Southern Lights”- Aurora Borealis and Aurora Australis, respectively. However, since the southern aurora occurs in the southern pole of…

appears a black, almost feather like appearance that is distinctly visible on the surface of the tree. The cankers form a light grey band on the bark which continues around the surface of the tree making the tree look almost like a candy cane. Fruiting bodies also are commonly protruding off the wood and grow with the canker lines. Underneath the cankers, the wood is a light grey.…

passed slender light emission daylight through a crystal situated in a dim room. Obviously all the noticeable range (red, orange, yellow, green, blue, indigo, and violet) was shown on the white screen. Individuals as of now realized that light went through a crystal would demonstrate a rainbow or noticeable range; however Newton 's trials demonstrated that diverse hues are bowed through diverse edges. Newton too thought all hues could be found in white light, so he passed the light during a time…

Furthermore Longfellow speaks about the woven petals by saying. “Brilliant hopes, all woven in gorgeous tissues, flaunting galy in the golden light.” This means that the flowers are most beautiful at night and blossom at night. Then Longfellow goes on to talk about the desires that one has at night. “Large desires, with most uncertain issues, Tender wishes, blooming at night!” Longfellow's is saying that people convey desires at night as well. (Longfellow's lines 25-28). Similarly to…

Darkness, all I could see was a black hole of twilight devouring what was left of the rim of light far beneath the cage. An ice cold breeze threw me upward. My heart was pounding; I could feel my heart leaving my rib cage, faster, and faster. The chains attached to the cage rattled as the vibrations flustered my thoughts. I was rising, the light below had disappeared. The upward motion sent my stomach across the cage. I started crawling to my stomach, reaching for food and water like a beast to…

Often containing didactic messages intended to persuade audiences into a certain set of behaviors or impress upon them a certain set of ideals, propaganda has been used by human culture and society for thousands of years. With the advent of the printing press in 1436 by a German goldsmith named Johaness Gutenberg, propaganda prints became more and more widespread and delivered with greater ease to the masses. The printing press became widely used throughout the modern world by the beginning of…

diffraction of light. His discoveries turned him as a glassmaker with humble beginnings into a scientists whose discoveries would allow scientists after him to calculate the distances of stars and lead them to recognize that the universe is expanding. On March 6, 1787 in Straubing, Bavaria, Joseph Ritter von Fraunhofer was born into a poor family where his father Franz Xaver Fraunhofer was a watch glass maker. At the age of 10, Joseph’s mother, Maria Anna Frohlich passed away, only a year…

In 1905, independent Danish astronomer Ejnar Hertzsprung and American astronomer Henry Norris Russell gathered data of a star’s spectral type and there temperature. They plotted these data on graphs and discovered that many patterns emerged linking the mass of a star to its lifespan. From the noted trends and correlations they formed what is now known as the Hertzsprung Russell Diagram or commonly referred to as the HR Diagram. The HR Diagram is used as an important tool in the study of…

In Paul Bogard's article "Let There Be Dark", builds an argument on every city using too much lighting in their houses, businesses, and street lights during the night. Bogard uses many methods to get his argument be heard by the readers on why we should limit our light using in the night when they're not being used. In his article, he uses a lot of ethos, pathos and logos, but he also puts in rhetorical question to make his argument reasonable with the information he gets and the effects that…

No one would have believed, in the last years of the 19th century, that physics was heading for a crisis. It seemed like all the large questions had been answered. The behaviour of bodies, from asteroids to galaxies, was predicted by Sir Isaac Newton 's laws of gravity and motion. Magnetism, electricity and light were linked by James Clerk Maxwell’s Equations. The understanding of the atom had reached the plum pudding stage, where an atom was a globe of 'stuff ' with the positive and negative…
