Is it a tumor? Magnetic Resonance Imaging (MRI) can tell. Your head is full of tiny radio transmitters (the nuclear spins of the hydrogen nuclei of your water molecules). In an MRI unit, these little radios can be made to broadcast their positions, giving a detailed picture of the inside of your head.

Tsetse flies are important vectors of human and animal diseases that adversely impact life in sub-Sahara Africa. A community of tsetse researchers (International Glossina Genome Initiative) have been working to obtain the full genome sequence of the tsetse species Glossina morsitans morsitans. The group have also mined the genome data to advance knowledge on functional aspects of tsetse and African trypanosome biology. This collection describes findings on tsetse's salivary gland biology, olfactory chemistry, lactation process, acquaporin proteins that play a role in lactation, oxidative stress responses during pregnancy, gut peritrophic matrix analysis and horizontal transfer events discovered in tsetse's genome from the symbiont Wolbachia. Further manuscripts reflect on the historical aspects of sleeping sickness epidemics that have plagued sub-Sahara in the 20th century.

These notes contain many sample calculations. It is important to do these yourself—type them in at your keyboard and see what happens on your screen—to get the feel of working in R.
Exercises in the middle of a section should be done immediately when you get to them, and make sure you have them right before moving on.
Many other similar introductions are scattered around the web; a partial list is in the “contributed documentation” section on the R web site (http://cran.r-project.org/other-docs.html). This particular version is limited (it has similar coverage to the standard Introduction to R manual and targets biologists who are neither programmers nor statisticians (yet).

This web page is an interactive physics problem on vector addition. The page explains the concept of breaking a vector into components and adding them together, and works through an example problem. The attached Java applet visualizes the problem. This is part of a collection of similar simulation-based student activities.

Created for a first-year university course, this linear algebra textbook takes an unusual approach: it introduces vector spaces at the outset and deals with linear systems only after a thorough introduction to vector spaces. This approach is based on the authors' experience over the past 25 years that students often need more time to master vector spaces while traditional textbooks relegate the topic to the end of the course. In this way, these new notions at the heart of linear algebra that are often considered abstract and difficult in an introductory course can then be used in the rest of the course as well as in different contexts.

In this activity, students will use vector analysis to understand the concept of dead reckoning. Students will use vectors to plot their course based on a time and speed. They will then correct the positions with vectors representing winds and currents.
