In the last few years, there has been an exciting growth of interest in questions about what we
do as human geographers and how we do it. Reflecting the general shift within the social
sciences towards a reflexive notion of knowledge, geographers have begun to question the constitution
of the discipline – what we know, how we know it and what difference this makes both
to the type of research we do and who participates in it with us either as colleagues or research
subjects … An intrinsic part of these debates has been a greater self-consciousness about research
Where did the water in the Oceans come from?

Though he was already dead, Frank Norris had a good year in 1909. His epic novel
Th e Octop u s (1901) was brou gh t to th e screen by vision ary film artist D. W.
Griffith—no other filmmaker has touched it since. Titled “A Corner in Wheat,”
the film is a confident, bare-bones distillation of the novel’s hundreds of pages
into fewer than fifteen minutes of viewing time. It is of course no substitute for
the original, a point compounded by the fact that Griffith drew on a second Norris
novel, The Pit (1903), also a rather long book....
The enclosure movement--the process by which the common-field system was broken down and replaced by a
system of unrestricted private use--involved economic and social changes which make it one of the important
subjects in English economic history. When it began, the arable fields of a community lay divided in a
multitude of strips separated from each other only by borders of unplowed turf. Each landholder was in
possession of a number of these strips, widely separated from each other, and scattered all over the open
fields, so that he had a share in each of the various grades of land.
Case in point, a student studying Physical Geography can learn about how mountains are formed, thus developing in him a deeper respect for the environment. Consequently, the student may decide to take such a class m order to make sure that our earth is protected from neglect in future generations.
There is a hidden revolution going on: geography is moving from niche to the mainstream. GIS for Web Developers introduces Geographic Information Systems (GIS) in simple terms and demonstrates hands-on uses. With this book, you'll explore popular websites like maps.google.com, see the technologies they use, and learn how to create your own. Written with the usual Pragmatic Bookshelf humor and real-world experience, GIS for Web Developers makes geographic programming concepts accessible to the common developer...
Mathematics is a way of organising our experience of the world. It
enriches our understanding and enables us to communicate and make
sense of our experiences. It also gives us enjoyment. By doing
mathematics we can solve a range of practical tasks and real-life
problems. We use it in many areas of our lives.
In mathematics we use ordinary language and the special language of
mathematics. We need to teach students to use both these languages.
We can work on problems within mathematics and we can work on
problems that use mathematics as a tool, like problems in science and
