article but because we are using a plagiarism tool online‚ I thought it would consider direct quotes as plagiarism even if I cite the source in my write up. The article I chose is 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

In “Helping Students Use Textual Sources Persuasively‚” Margaret Kantz talks about how individuals should read texts to write a synthesis essay. To write a synthesis essay‚ one should be able to come up with an argument and find information from other sources‚ and use them as proofs to back up the argument. First‚ Kantz talks about the mistakes that students usually make when they write this essay. For instance‚ Shirley made a mistake by reading a repeating and telling the story instead of creating

Acoustic Theory and Synthesis Frequency: Frequency means the number of cycles per second and depending on the amount of cycles per second determines how high or low pitched the sound is and the time that it takes to complete one cycle is called the period. Frequency is measured in Hertz (Hz). And An average human is able to hear sounds between 20Hz and 20‚000Hz. As the cycles per second increases‚ the smaller the wavelengths become‚ therefore there is a higher frequency which will cause
