You will need speakers to fully enjoy this site, but most information can be obtained without the sound. The pages can be paused, advanced, rewound and the sound may be controlled from the menu system at the bottom of the page. The left hand content menu allows you to look through the list of pages.Some text boxes are scrollable -- use the keyboard up and down keys or the mousewheel to do this.
Be aware that there are some very large file sizes here. Those downloading from a modem should consider requesting a CD copy from the lecturer.
Above, all enjoy and learn.
