If x lies on an edge, then each of the two points in [x] has a half-disc-like neighbourhood (see Figure 107). When we identify edges, these neighbourhoods fit together to form disc-like neighbourhoods in the Klein bottle.

If x lies on an edge, then each of the two points in [x] has a half-disc-like neighbourhood. When we identify edges, these neighbourhoods fit together to form disc-like neighbourhoods on the torus, as Figure 105 shows.

In this subsection we formalise the idea of a net by introducing a useful concept called a subdivision of a surface. This is a standard kind of net drawn on a surface, and is defined in terms of vertices, edges and faces. It leads to the idea of the Euler characteristic of the surface.

All surfaces obtained from polygons by identifying edges arise from a net (of sorts) consisting of a single polygonal face, together with the edges and vertices that remain aft

The idea of orientability is another fundamental concept that we need for the study of surfaces. To illustrate the underlying idea, we consider two familiar surfaces â€“ a cylinder and a MÃ¶bius band.

We can distinguish between a cylinder and a MÃ¶bius band by noticing that every cylinder has an â€˜insideâ€™ and an â€˜outsideâ€™, as shown in Author(s): The Open University

Animals at the extremes: The desert environment
Animal life has adapted to survive in the most unlikely and inhospitable habitats. This free course, Animals at the extremes: The desert environment, looks at the surprisingly diverse desert climates throughout the world and mammals, birds, lizards and amphibians that survive there. It splits these animals into three groups according to their strategy for survival: evaders, evaporators and endurers, then discusses how these strategies work on a biochemical and physiological level.

This course will allow you to extend your visual modelling skills through the use of the sign graph diagramming technique. You will explore the dynamic relationship between social, economic and ecological factors whose interdependencies will determine the complex dynamics of the future as it unfolds. Your final task will be to identify points of intervention within this complex system in order to "nudge" the situation towards a more favourable outcome.

This OpenLearn course provides a s

NASA | The Evaporative Stress Index
The Evaporative Stress Index (ESI) provides objective, high-resolution information about the evaporation of water from land surface. The ESI model combines satellite data with other meteorological factors to determine how much water is used by crops and vegetation. The resulting data helps to detect drought. The kind of early-warning detection system ESI provides will enhance the US arsenal of drought monitoring tools and help farmers adapt to drought before it evolves.
