Title: Who typset the math in this thing? Review: I realize that this is a layman's version of the theory, but couldn't someone at the publisher really take the time to typeset the equations correctly? They don't make any sense and they aren't set up right.Also, although this is translated from Einstein's German version, there are books that better explain his theory of Relativity. He wasn't all that good at it. However, it is an inexpensive alternative for my research. Does this product review convey a negative or positive sentiment?

Title: Good Deal Review: Although these aren't the highest quality chairs out there, for the price they're a steal. They look great (just some minor flaws in the finish and workmanship) and are pretty comfortable too. They did take a long time to put together, but nothing a former Ikea junkie like myself couldn't handle. Does this product review convey a negative or positive sentiment?
Positive
