Why didn't any one tell me about this book when I was younger! This is so good. :)

As someone who struggled through calculus, this book would have made a huge difference for me. Just reading through the first few pages brought a smile to my face that someone could so plainly explain these critical concepts in such a familiar way. Why didn't my professors do that?

> Why didn't my professors do that?

Because to them it's obvious. Most maths teachers are so far ahead of the students they forgot they once were students themselves.

I've had 3 different ones in high school and the difference was incredible. All the way from 'only the best students learn anything' to 'everybody earns at least a passing grade'.

Maths and physics were the classes where the quality difference between the teachers stood out the most.

It's crazy the kids have to pay hundreds of dollars for the horrible books the colleges require when brilliant things like this can be had for free...

It's not rare that supports the people teaching the class. Nothing like pushing your own book to students that just have to buy it. In some cases the books don't even get used.

That PDF is just a bunch of scanned images of the book. It's large and cumbersome in many readers. There is a much better PDF at Project Gutenberg [1]. The Gutenberg PDF is only 1.9 MB, compared to 12 MB for the scanned image PDF. The Gutenberg page for this book [2] also has a link to the LaTeX source for the PDF.

You say 1.9MB, the Gutenberg page says 1.8MB, and the download itself is only 1.18MB thanks to gzip. The main difference is that the Gutenberg PDF is a transcribed, cleaned-up version. As much as this probably makes me sound like an audiophile, I actually prefer the raw scans over what may essentially be a reprint. They show all the blemishes, unofficial additions, and other marks that make the book look more "real"…

The PDF is 1892715 bytes = 1.892715 MB. I rounded to two significant digits, giving 1.9 MB.

When Gutenberg says 1.8 MB they probably actually mean 1.8 MiB. 1892715 bytes = 1.80503368377685546875 MiB, or 1.8 MiB to two significant digits.

Earlier quoted context omitted.

1914 is pretty modern.

It's all relative. Obviously I mean that it sounds vastly more recent than 1914 to my ear. And anyway, I confess I don't know the industry at all, but I doubt anyone would talk about 1914 as representing 'modern publishing'.

It's less than a decade from the cutoff date after which books stopped entering the public domain, so by Project Gutenberg standards, it is pretty modern.

And a slightly updated physical version as well http://a.co/gI4K8oe
