1999. H Hardcover. New. 320pp. This book is amazing! It will teach anyone who feels that they draw like a child to learn to draw stunningly realistic drawings within the time it takes to work through the book(about a month). An superb example of true education, showing that everyone possesses the inherent ability express their vision through drawing, and that our lack of this ability is solely due to our lack of know-how, received through the poor or non- existent art education given in our schools. Book Jacket: ìTranslated into thirteen languages, with more than 2.5 million copies sold, Drawing on the Right Side of the Brain is the world's most widely used drawing instruction book."--BOOK JACKET. "This twentieth-anniversary edition of Drawing on the Right Side of the Brain has been dramatically revised, with more than fifty percent new material, including: recent developments in brain research that relate to drawing; new insights on the use of drawing techniques in the corporate world and in education; instruction on self- expression through drawing; ways to step beyond black-and-white drawing into color; and detailed advice on applying the five basic skills of drawing to solve problems."

It teaches the reader to approach a book from several narrowing perspectives, developing a quick and full overview of the work. Scheele then shares the techniques of "PhotoReading" where one scans the entire book with an unfocused gaze in order to transfer it photographically into the right brain. He follows up with the development of recall of this memory, along with continued closer analysis of the book as needed. Very promising as a tool to digest and integrate large amounts of information.

New York: Delacorte Press. 1998. F First Edition. H Hardcover. New. Science 322p. We suggest this title for a introduction to the more interesting modern day approaches to Expedient Learning, while tracing them back to the genius of Leonardo. This is an inspiring and inventive guide that teaches readers how to develop their full potential, using the principles of Da Vincian thought identified by the author. Beginning with a brief historical biography of Da Vinci and an overview of the astounding advances made in the arts and sciences during the Renaissance, Gelb illustrates the seven fundamental elements of Da Vinci's thought process: Questionare: A questing, insatiably curious approach to life Dimostrazione: A commitment to test knowledge through experience Sensazione: The continual refinement of the senses, especially sight, as the means to clarify experience Sfumato: A willingness to embrace ambiguity, paradox and uncertainty Arte/Scienza: The development of the balance between science and art, logic and imagination. "Whole-brain" thinking Corporalita: The cultivation of ambidexterity, fitness and poise Connessione: A recognition and appreciation for the interconnectedness of all things and phenomena. "Systems" thinking. Loaded with practical exercises, quotes, sidebars, illustrations and material drawn directly from Da Vinci's personal notebooks, How to Think Like Leonardo Da Vinci is both a tribute to his great achievements and a call to carry on his legacy in our everyday lives by utilizing our potential to the best of our ability.
