Students work in pairs or small groups to experiment and make conjectures. Each exploration is followed by full class discussion to connect and consolidate ideas about change and give students practice in communicating and justifying their conjectures. In addition, students get direct experience with concepts of measurement. Solutions to many of these problems are achieved through mathematics. We will discuss how to detect and correct errors in digital messages, how to send secure messages, and ways to minimize the information necessary to transmit images.
Wavelets form one tool that is being used in many different areas.
Applications for wavelets have been found in image compression, the restoration of audio recordings, seismology, magnetic resonance imaging, and the world wide web to name just a few. We will discuss the basics of how and why wavelets are used and illustrate with examples from image compression and video search engines for the world wide web. This is a joint talk with Edward Aboufadel. You, too, will begin to question what you really believe when you experience some of these mathematical paradoxes.
