called‚ “Synthesis of a Genius” by George Kauffman and Steven Chooljian. The area of exploration and discovery that I chose was the synthesis of urea in chemistry. Urea was discovered by Friedrich Wohler‚ in 1828. This discovery ultimately changed the belief at the time that only organic compounds can be created from living organisms. He was able to create urea (which is mostly what is found in human and animal urine) in the lab with inorganic compounds. The interesting thing about this was

A gene is a sequence of nucleotides‚ it is important because they form the template and these templates are used for synthesizing proteins. 3. a. Transcription is the first step of protein synthesis it uses a sequence of DNA nucleotides to produce a sequence of RNA nucleotide. b. RNA polymerase bonds to RNA nucleotides together

Experiment 4 Synthesis of Salicylic Acid Introduction Throughout history‚ botanical extracts have been used as medicines. Approximately 30% of all medicines have a plant origin. This number increases to 60% if you consider medicines that at one time were derived from plants‚ but have been synthesized in the laboratory. Salicylic acid is a white crystalline compound that can be isolated from the bark of birch trees. Since it is a valuable substance that can be isolated from nature‚ it is called

The Cave and the Christian In Plato’s Republic we have one of the best allegories told‚ the allegory of the Cave. The allegory of the cave goes basically like this: Suppose people were born in a cave and from birth they were chained up and unable to turn their heads. All they could do was to look straight ahead at a wall. Far behind them there was a fire burning and in from of that fire people would walk with object in their hands‚ statues and the like. All the chained prisoners could see would

Experiment 13: Synthesis of 1-Bromobutane An SN2 Reaction Experiment #13: Synthesis of 1-Bromobutane an SN2 Reaction Introduction: In order to synthesize 1-Bromobutane an alkyl halide must be present to undergo a nucleophilic substitution reaction of an alcohol. Since 1-butanol is a primary substrate it will undergo an SN2 reaction with sodium bromide in order to convert the alcohol group to water which is a better leaving group and will in the end produce 1-bromobutane.

Explain Plato’s Analogy of the Cave Plato (428-348BC) was a student of Socrates and was the teacher of Aristotle. He is said to be one of the most revered philosophers of all time. He produced a lot of work but one of his major works was “The Republic” which was written in the middle section of his life.

Plato’s Allegory of the cave in The Matrix‚ it swirls together Plato’s ideas with a realistic feel. The things that are most clear in The Matrix that relate back to the Allegory of the cave are‚ the forms‚ the blinding soon‚ the escaped prisoner‚ the fire‚ and the idea that the prisoners were living under a blank of lies. The connection between Plato’s work and the work of The Matrix is too strong for it to be unintentional. In Plato’s ideas of the Allegory of the cave‚ the forms play a key part

Well‚ like lots of cave art‚ most scenes portray large wild animals‚ such as bison‚ horses‚ or deer‚ with horses being the most common.

Plato’s Allegory of the Cave is Plato talking to Socrates and Glaucon about the idea of human being. Plato‚ being a philosopher‚ wondered about a lot of things. He‚ of course‚ had meant to put meanings behind the dialogues that he writes down‚ Allegory of the Cave being one. The central idea of it is that he believes humans are creatures that only wander around in places that they know‚ and whenever they leave the cave‚ they see a whole new world. Throughout the entire text‚ he develops the idea
