Throughout history humans have looked upon light as a symbol of truth and their source of hope and strength. Ayn Rand uses the light as a symbol of truth in her book Anthem. The main character, Equality lives in a dark society where he symbolizes the light. His rebellious nature and discovery of the electric lightbulb makes him an outcast which leads to his discovery of egoism, an idea that had become extinct and outlawed. Ayn Rand uses Equality’s discovery of light and his relationship with the

Anything can happen in your dreams. You can turn invisible, go to space, travel to a foreign country, walk over the Grand Canyon, swim with dolphins, fly an airplane, run with cheetahs, or even meet Beyonce at school while she is singing in the cafeteria. Dreams have been a big topic to researchers all over the fields of science. Scientists of the biological side study the processes that occur in our brain as we sleep. Scientists on the psychological side study the dream on waking life ( hours spent

Equality is something people want till people actually have it. Equality often limits a person’s abilities and disables to do something for themselves or inspire themselves. Equality's, the main character in the book Anthem, the primary motivation is proving that he is smart enough to become a scholar. Equality has a right to be motivated in this way since he believes that he can help the society so he is giving into the collectivism. I think that if everyone was motivated in this way, there would

The inventions would impact people in life and their work. In Thomas Alva Edison's time he was trying to find a clean way for light in a room. In 1888 Edison solved that problem with a smaller efficient and a cleaner light in a room. Thomas Alva Edison created the first incandescent light bulb. The way it would work is that their would be some bamboo filament in the bulb under the part where the light would start. This filament would run about 1200 hours. The filament would mostly run the whole bulb

Do you ever wonder what life would be like without electricity? In 1847, Thomas Edison, the inventor of the famous incandescent light bulb, was born. Without his birth, we would not have electricity, which is now a necessity in American civilization. The incandescent light bulb burned longer, replacing carbon filament films. Without the light bulb, or the Industrial Revolution, America would not be what it is today. Thomas Edison was essential to evolution and had an interesting childhood, and the

Just like every person has their own journey through life, every character has their own quest on which they embark and learn from. In Thomas Pynchon’s The Crying of Lot 49, the main character, Oedipa, undertakes a quest of not only fulfilling her duties to her ex boyfriend, Pierce, but fulfilling something within herself as well. Pynchon’s application of the quest model in this book portrays Oedipa’s personal development through use of symbolism and metaphor, and also brings forth greater implications

Throughout A Streetcar Named Desire, Tennessee Williams uses symbolism to reveal aspects about the characters. Williams uses light and dark to symbolize Blanche’s need to live in an illusion showing how people often struggle to accept the harsh truth of reality. Throughout the play Blanche tries to hide who she really is and creates her own fantasy to live in. One of the first times we see Blanche start to set up her illusion is through the use of the paper lantern. Blanche asks Mitch to place a

commercially viable lightbulb is supported by the quote ‘I have not failed. I have just found 10,000 ways that won’t work.’ The lightbulb had been around for many years but the product available was expensive, short-lived and unreliable. By creating a vacuum inside, using the correct filament and running a lower voltage through the bulb, it would last a lot longer. These were substantial improvements that changed the world in regards to artificial lighting. At first, his invention was able to produce

Table 1 mentions the Column volumes of Gel Filtration experiment: Void Volume (Vo), Elution Volume (Ve), Included Volume (Vi), Entire Volume (Vo + Vi), and Inert Volume (Vg). Void Volume (Vo) came out to be 1.25 ml. It was calculated by adding all the fractions that contained blue dextran. Blue Dextran was the biggest substance in size which made it impossible to fit in the available pore sizes of the beads. Void Volume represents the space between the beads in column. In addition, Elution Volume

450M NaOH. The actual molarity of the NaOH concentration used was found to be 1.5M NaOH. The percent error of the results resulted in 72%. The large error may have occurred due to over titration of the NaOH, as the color of the solution in the flask was a darker pink in comparison for the needed faint pink. Discussion of Theory: Titration is the basis of the Titration Lab because the goal of the lab was to titrate. Titration is determining the concentration of a solution by neutralizing it

in a vacuum sealed bag is the best way to keep the meat fresh. You can just seal the meat up and store in a cooler or freezer. The great thing about a vacuum sealed bag is that the air seals up the meat without leaving any inside the bag. Ziplock bags have a tendency to not close properly, and the air inside the bag will cause meat to go bad faster. Meat may lose its flavor if you don’t properly seal the bag. Any meat that you buy from the store or you have hunted can store in a vacuum seal

Introduction Burger King is a fast food chain that originated in the United States, serving hamburgers with a side of french fries. As well known as Burger King is, their marketing team is always trying new ways of advertising their burgers. In 2009 this Burger chain ran an advertisement throughout Singapore that created a lot of controversy, but not for the effectiveness. Rather, for the imagery used. It depicts a woman with mouth wide open, with Burger King’s new hamburger right in front of her

(1) The purpose of the separation lab procedure was to help my group members and I successfully formulate our own plan before completing the experiment, handling multiple materials and substances, etc. It acted as a step-by-step plan that guided us throughout the experiment and ensured that we were well prepared ahead of time (ie. knowing what kind of materials were necessary and gathering the correct measurements of each substance); this made the experiment day much less hectic for all of us. It

three Erlenmeyer flasks are required. Set the spectrophotometer to 540nm. Number the flasks from one to three and add 30 milliliters of enzyme extract the flask marked one on it. It is best to split up the work into three groups. Next, add 20 milliliters to the flasks marked two and three. Pipette 10 milliliters of enzyme extract from flask one to flask two making a 1:3 solution of water and enzymatic solution in flask 2. Next, Pipette 10 milliners of flask twos 1:3 solution into flask three creating

many filtration procedures in the experiment, as not all of the product was poured out from the flask, onto the filter. Since, recrystallization could not be done, the benzoic acid was immediately transferred onto the watch glass, and it is when transferring some product could have been left on the filter. Overall, pouring product into the filter, and trying to get every particle of product from the flask for each filtration procedure in the experiment, is rather difficult, and is impossible to get

obtained, and then individually placed in a 100 mL erlenmeyer flask up to the 25 mL mark. Then, a UV VIS spectrometer was connected to a laptop with the program Logger Pro. It was then calibrated by filling a cuvette to the three-quarter mark with deionized water, and running it through the calibration tool present in the program. After the spectrometer was calibrated, 5 mL of yellow dye was placed in another cuvette from the erlenmeyer flask using a 5 mL transfer pipette. The absorption level of each
