‘All great ideas are controversial or have been at one time’ All pieces of art that have challenged‚ questioned or opposed stereotypical beliefs or traditional values are regarded as great ideas. Artists such as Marcel Duchamp‚ Andy Warhol and Kara Walker are all significant memorable artists that have a tendency to disregard high art and produce works that break down conventional ideas of the time. These outrageous and opposing perspectives of the time period have been developed via conceptual

Andy Warhol Andrew Warhola is considered to be the “founder and a major figure of the pop art movement”. He was born in Pittsburgh Pennsylvania in 1928. He graduated from the Carnegie Institute of Technology‚ where he majored in pictorial design. He worked as an illustrator in many magazines including Vogue‚ Harpers Bazaar and the New Yorker‚ but‚ his big break was in 1949‚ when he illustrated for Glamour Magazine.

Name: Date of experiment: 04/02/12 Date of report: 04/03/12 Title: Oxidation – Reduction Activity Series Purpose: To determine relative oxidizing and reducing strengths of a series of metals and ions. Oxidation and reduction reaction occur simultaneously side by side. A reduction reaction occurs only if an oxidation reaction occurs and vise-versa. Electrons are given in oxidation while in reduction electrons are gained. Oxidizing agent is a chemical substance which has a large tendency to

1. Mechanism of oxidation process In an oxidation process of silicon that usually takes place at very high temperature (thermal oxidation)‚ silicon (Si) reacts with either water vapor (H20) or oxygen (O2) to form silicon dioxide‚SiO2 on the silicon surface. The reaction is represented by following equations: Dry oxidation: Si + O2 → SiO2 Wet oxidation: Si + 2H2O → SiO2 + 2H2 The oxidation process can be implemented through diffusion

history‚ in a similar way to what writing tells us‚ from oral history. Without many of the artworks that we now have‚ we would not have a clear look at what all happened. Some examples of this are Ti Watching a Hippopotamus Hunt and Race Riot by Andy Warhol. These two very different pieces show different historical situations that were happening in that time period. For the Ti mural‚ we see that people in Ancient Egypt found hippo hunting to either be important or was common to a point that it became

their practice. JACKSON POLLOCK AND ANDY WARHOL Jackson Pollock and Andy Warhol were American based artists during the same period; the 1940s‚ 50s‚ and 60s. Almost every aspect of their art is antonymous and extremely different‚ from their art practice‚ to the meaning they constructed in their works‚ to the audience and world they reflected. Jackson Pollock wasn an Abstract Expressionist who used the Action Painting style‚ as opposed to the Colour Field Painting style. He was active in the 1940s

potassium permanganate solution was titrated thrice to give clear Mn2+ with an analyte of acidified FeSO4 until all the Fe2+ in the solution was oxidized to Fe3+. The color of the MnO4-/Mn2+ was used as the indicator for the titration. A balanced oxidation-reduction‚ the molarity/normality of the standards potassium permanganate‚ and the volume of potassium permanganate used allowed the determination of the concentration of the FeSO4. Equipment and Chemicals: Chemicals: * Iron (II) ammonium sulfate
