Question:What is the music on the main page?	Answer: "Tempus Transit Gelidum" From Carmina Burana by the Augsburg Ensemblue origins from the 13th century. Here is the lyrics in latin. The tune is not quite for this time, because it describes life when spring begins.
Question:Is it ok to use an older edition of a textbook.	Answer: It is not really necessary to use a text book. Look around and take, what suits you. We will not follow a textbook nor use homework from textbooks so that it is fine to use an older edition. Newer editions tend to be more reliable and are smoothed out. Books liks Stewart also resell well again.
