This resource consists of an extensive pre-lab tutorial, (examining the relationships between size, funtion, and morphology in selected vertebrates and invertebrates), and a manual for carrying out an associated laboratory exercise in comparative morphology. This exercise is suitable for introductory biology courses in vertebrate and invertebrate biology, and may be adapted as a supplement to any course dealing with size / structure / function relationships.
Web site contains java applet which simulates an airfoil. The user can change the shape of the foil, the type of object used (including a cylinder and sphere), the speed of the foil, the altitude, and even the fluid used. The simulation calculates the lift based on the parameters chosen. Various plots illustrating the dependence on some parameters can be shown.
The article presents and explains the diamond-shaped pattern that appears in the rocket engine and jet engine exhausts. Several photographs illustrate this phenomenon, and images show how crisscrossing shock waves produce the diamond shapes.
This essay with a field journal covers how the Wisconsin Glacier created most of the landforms of Long Island. It also explains how storms, erosion, and other forces continually reshape the island and how the shifting of the continents millions of years ago changed the location of Long Island on the globe. Attention is also given to how its landforms have influenced its land use and the types of buildings erected there. Some glacial features explained include: terminal, recessional, and ground moraines; outwash plains; erratics; and kettle lakes.
The largest of the Giza pyramids is usually called the Great Pyramid. It can also be called the Great Golden Pyramid, because its geometry is that of the Golden Mean. Pictures and diagrams of the interior and exterior architecture, with explanations of the related math, astronomy, and physics. References included.
