The Great Courses (Firm)
Description
We commonly define the Pythagorean theorem using the formula a2 + b2 = c2. But Pythagoras himself would have been confused by that. Explore how this famous theorem can be explained using common geometric shapes (no fancy algebra required), and how it’s a critical foundation for the rest of geometry.

Description
Logic is intellectual self-defense against such assaults on reason and also a method of quality control for checking the validity of your own views. But beyond these very practical benefits, informal logic—the kind we apply in daily life—is the gateway to an elegant and fascinating branch of philosophy known as formal logic, which is philosophy’s equivalent to calculus. Formal logic is a breathtakingly versatile tool. Much like a Swiss army...

To complete your study of cast shadows, learn to draw shadows produced by oblique light coming from both the front and rear of objects. Then investigate artificial light as it affects shadows projected by objects within interiors. Practice these principles by drawing a complex interior and an invented still life from your imagination..

Put your knowledge of value into practice, beginning with still lifes of white objects on white backgrounds drawn in a broad palette of light to dark. Learn to see a color’s value as distinct from its hue and saturation. Realize a range of value-based projects, from drawings combining interior and outdoor spaces to portraits, full-figure drawings, and drawings translating color to value..

Now examine the "second round" of Indian nationalist action against the British Raj. Witness the effects on India of the global economic depression after 1929, which triggered the Civil Disobedience Campaign, a massive boycotting of British goods, services, and institutions. Assess the Raj's countertactic of extending constitutional concessions to stem nationalist agitation.

Look broadly at how artists create flatness, volume, and space on two-dimensional surfaces. In doing so, study 12 factors that affect how we perceive depth of space, encompassing principles such as overlap, the relative scale of objects, the use of diagonals and foreshortened shapes, atmospheric perspective, and how distance affects color..

Investigate visual strategies artists use in composing drawings. Grasp how shapes communicate, and how the factors of contrast and repetition affect how a viewer reads a drawing. Learn about visual “rhyming” (shapes and directions that get repeated rhythmically), spatial organization (foreground, mid-ground, background), and the narrative possibilities of composition..

In approaching composition, study the underlying structure of rectangles, the fundamental shape of most drawings. Learn how the character of any rectangle is defined by the relationship of its verticality to its horizontality, and how this relationship affects our perception. Observe how simple diagonals within a rectangle offer numerous possibilities for visual interpretation..
