Types of Deserts
Deserts are classified by their location and dominant weather pattern into several types: trade wind, midlatitude, rain shadow, coastal, monsoon, or polar deserts. Former desert areas presently in non-arid environments are paleodeserts, and extraterrestrial deserts exist on other planets. This site, produced by the U.S. Geological Survey, describes each type of desert using text and photographs.
This popular maths talk gives an introduction to various different kinds of infinity, both countable and uncountable. These concepts are illustrated in a somewhat informal way using the notion of Hilbert's infinite hotel. In this talk, the hotel manager tries to fit various infinite collections of guests into the hotel. The students should learn that many apparently different types of infinity are really the same size. However, there are genuinely more" real numbers than there are positive integ
Superspace: One Thousand and One Lessons in Supersymmetry
We introduce superfields in chapter 2 for the simpler world of three spacetime dimensions, where superfields are very similar to ordinary fields. We skip the discussion of nonsuperspace topics (background fields, gravity, etc.) which are covered in following chapters, and concentrate on a pedagogical treatment of superspace. We return to four dimensions in chapter 3, where we describe how supersymmetry is represented on superfields, and discuss all general properties of free superfields (and the

Igneous Rocks of the Ocean Basins
These lecture notes introduce magmatism and petrology as they relate to the oceanic lithosphere. The notes cover ophiolite sequences and types of volcanic settings found in ocean basins. A section about basalt includes discussion of location, composition and origin of mid-ocean ridge basalts. Ocean ...
Metamorphic Rock Textures
These lecture notes discuss metamorphic textures and the mechanisms that create them. A discussion of foliation covers types of stress and the development of foliated rocks from slate to gneiss. Five modes of metamorphic differentiation are introduced including preservation of original compositional ...
Efficient Computer-User Interface in Electronic Mail Systems
This research explores the question of improving user- computer interface. The approach is one of observing and codifying various parameters that influence the efficiency of interface in the context of electronic mail tasks. In the paper the authors observe 'expert' and 'regular' users of a mail system and analyze the sources of efficiency. It is clear that experts use a different, more specialized, set of commands in performing standard mail tasks. While experts perform these tasks with fewer e
