Semi-Riemann Geometry and General Relativity
This book represents course notes for a one semester course at the undergraduate level giving an introduction to Riemannian geometry and its principal physical application, Einstein’s theory of general relativity. The background assumed is a good grounding in linear algebra and in advanced calculus, preferably in the language of differential forms. This book covers the following topics: The principal curvatures; rules of calculus; Levi-Civita Connections; bundle of frames; connections on prin

Basic Programming in a Scripting Language - Andrew Jackson
An introduction to the Ruby language for the Computer-Aided Discovery Methods course taught at Baylor College of Medicine.
This interactive article looks at research findings over the past few decades that concludes birds are, in fact, a kind of theropod dinosaur. The article includes the following: An overview explaining how scientists identify and classify new specimens; An introduction to the finding that theropod dinosaurs, like Velociraptor, are more closely related to modern birds than they are to almost any other kind of dinosaur; A detailed answer to the question, What is a theropod? An interactive that allo
In this hands-on OLogy activity, kids learn about matter by building their own models of carbon out of pipe cleaners, wire, and clay. The activity begins with a kid-friendly introduction to matter, elements, and atoms. The illustrated, step-by-step directions show kids how to use the information about carbon on the Periodic Table to create a mobile that shows the element's basic structure. A PDF version of the Periodic Table, along with a kid-friendly overview of how to read it, is also included
The Adventures of George Amato, "DNA Detective"
This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they see how DNA is used to solve crimes against animals. The activity starts with an introduction to George Amato, an AMNH scientist who sometimes helps the U.S. government solve mysteries. In a three-part online slide show, students see how Amato earned the title "DNA Detective" in 1993 when he helped the U.S. Fish and Wildlife Service catch someone trying to sneak protected re
Mint Your Own Coin
This OLogy activity explores the symbolic and archaeological importance of coins. The activity opens by introducing kids to the elements of coins: dates, names, images, mottoes, and materials. Then, kids are given step-by-step illustrated directions for designing a coin. The activity includes a Global Coin Collection, a printable PDF handout with photographs of coins from 14 countries, and an introduction to the kid who has collected these coins.

Discovering Important Statistical Concepts Using Spreadsheets
The Discovering Important Statistical Concepts Using Spread Sheets (DISCUSS) project is a modified and supplemented web-based implementation of the initial DISCUS materials for teaching elementary statistics at the introductory level. The site aims to integrate the powerful interactive capabilities of Microsoft Excel with the convenience of web-based resource materials using Microsoft Internet Explorer. There are several modules within the project. Modules include, [no comma] charts and graphs,
Star Library: What Makes the Standard Deviation Larger or Smaller?
The activity is designed to help students develop a better intuitive understanding of what is meant by variability in statistics. Emphasis is placed on the standard deviation as a measure of variability. As they learn about the standard deviation, many students focus on the variability of bar heights in a histogram when asked to compare the variability of two distributions. For these students, variability refers to the “variation” in bar heights. Other students may focus only on the range of
