John, Betty, and their dog Trevor solve a series of problems designed to introduce topics such as: - integers - fractions - surds - imaginary numbers - complex numbers - Argand diagram - vectors - multiplication in polar form - relating polar and Cartesian form - De Moivre's theorem - Mandelbrot set To order the book in hard copy, you may use the form provided on the Web. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- POWERS OF TEN - Bruce Bryson http://www.wordwizz.com/pwrsof10.htm A visual journey from quarks to quasars: images based on the book _Powers of Ten_, by Philip and Phyllis Morrison and the Office of Charles and Ray Eames. Each picture's subject is ten times wider or narrower than the next. Images range from quarks at 10^-16 meters to groups of galaxies at 10^25 meters, with related information about objects of each size and Java animations of the images.
