Texting and instant messaging are familiar and popular communication techniques. Text messages composed of ASCII characters, with each character composed of eight bits, ultimately form a stream of bits transmitted from the source to the receiver. Normally the text message moves through a complex data network, and the user only sees the endpoints of the system. In this project, however, you will be able to follow the text message on its complete journey through a binary ASK transmitter, a speaker-air-microphone (SAM) channel, and a binary ASK receiver.

In this problem-based learning activity, students experiment with a battery and light bulbs to build your own flashlights. The purpose of the activity is to develop understanding of fundamental electrical circuit concepts, including voltage, current, and closed circuits, and to help eliminate common misconceptions. This module provides instructor information for the activity.

University Physics is a three-volume collection that meets the scope and sequence requirements for two- and three-semester calculus-based physics courses. Volume 1 covers mechanics, sound, oscillations, and waves. Volume 2 covers thermodynamics, electricity and magnetism, and Volume 3 covers optics and modern physics. This textbook emphasizes connections between between theory and application, making physics concepts interesting and accessible to students while maintaining the mathematical rigor inherent in the subject. Frequent, strong examples focus on how to approach a problem, how to work with the equations, and how to check and generalize the result.

This course, as the name suggest, is intended to help authors who want to publish mathematical content on web. The emphasis here is to enable learners to quickly adapt to the extensive mathML markup language and begin writing codes even without a specialized editor, available commercially. The course is presented in the form of a tutorial, which essentially saves on unnecessary details. This tutorial is not intended currently (may be supplemented later with the help coming from others) to be a comprehensive treatment on mathML. The presentation here is restricted to areas which form the basic part of the electronic publication of mathematical content.
