The value of a stock is whatever someone is willing to pay for it. The value of real estate is also whatever someone is willing to pay for it. It doesn't make sense to say that a stock is trading at some other price that what it's valued at.
Having said that, you should know that real estate is also selling at what could be considered as high P/E values, where in this case the "E" is the rent minus costs like insurance and maintenance. For a coherent description of this situation, check the editorial of this week's Economist.
This seems like a thoroughly good idea. It would enable the schools to have up to date textbooks without the need to buy a new set of books every time the author decides to release an update.
Enterprising students should also find something in there to peak their interest - I know I would have loved to have one of these babies when I was that age !
That's not actually the argument for why the number of primes is infinite. Rather, assume there are only finitely many prime numbers. Multiply all of them together. Add one to this number. It is easy to show that this number is not divisible by any of the finitely many primes you started with. Hence it must be a prime number as well.

A lot of the quant action is in valuing and hedging options. A good primer on what options are, how to use them and some of the basic aspects of pricing and hedging is the book by Hull, also recommended by some other people here.
It is a bit of a stretch to consider his book technical. The mathematics behind options valuation is stochastic integration (or stochastic differential equations), which is slightly mind-boggling at first. A good and reasonably simple book on this theory was recently published by Steven Shreve and is called Stochastic Calculus for Finance. It is two volumes and the meat is in volume II.
Understanding this theory does require a certain amount of mathematical sophistication.
The standard academic sources for stock quotes in US markets are CRSP (for daily quotes) and TAQ (for transaction-by-transaction) databases. Both are currently maintained at Wharton and are not free.
I recently got a Toshiba SD-H400 off ebay for a bit over a hundered bucks after rebates, which includes a lifetime subscription to a stripped down version of TiVo.
The authors need to spend more time thinking about what the intended target audience is. In the current state of the book, I can't really think of any audience that could benefit from it.
For example:
To make it useful for students new to calculus, it would be helpful to discuss limits _before_ defining the derivative.
To make it useful for students comfortable with calculus, there is less need for motivating the derivative, but there should be lots of easily referenced results.
Online dictionaries are very different since the target audience is more or less defined as the people who would need to look up the term.. you don't expect too many precalculus students to look up the definitions in differential geometry.

Nobody goes there anymore. The place is just too crowded, you know ?
