Title: Great reference text Review: As an undergraduate physics major I'm required to take a course in math methods of physics, and Boas is the required text. Not only did I save money by purchasing online, but this book is FANTASTIC. The text itself support the arguments we cover in class, but the book knows no bounds. In my other physics and math courses I've already looked up topics and found a complete and easily understood explanations. I'm definitely not selling this one after the course is over.Just as an update, I'm now taking a course in Complex Analysis with my college's math department, and three weeks into the semester have yet to experience any difficulty with the material since, for the most part, I covered it already in Boas.

Title: Mount Hagen Organic Freeze Dried Instant Coffee, 3.53-Ounce Jars (Pack of 6) Review: As an instant coffee, this is the best (organic or not) out there. It's not quite as good as a probably brewed coffee but it's a good substitute when convenience is more important. The coffee tastes rich and smooth and doesn't have an overly acidic or bitter aftertaste. Price is steep but it's hard to switch back after trying this. Amazon has the best price with subscribe and save because most stores sell them for $8.99/each. Does this product review convey a negative or positive sentiment?
