Stress is defined as the quantity equal to ... what?
In introducing the very concept of the stress tensor to the beginning student, text-books always present only indirect relations involving the concept. Thus, you have the relations like "traction = (stress-transposed)(unit normal)" (i.e. Cauchy's formula, for uniform stress), or the relations for the coordinate transformations of the stress tensor, or the divergence theorem (for non-uniform stress). These are immediately followed or interspersed with alternative notations, and the rules for using them.
But what you never ever get to see, in text-books or references, is this: a *direct* definition of the stress tensor, i.e. an equation in which there is only the stress tensor on the left hand-side, and some expression involving some *other* quantities on right hand-side. Why? What possibly could be the conceptual and pedagogical advantages of giving a direct definition of this kind, and its physical meaning? I would like to ponder on these matters here, giving my answers to these and similar questions in the process.

Tossing your Smartphone
If you are teaching a course on vehicle dynamics, navigation, robotics, or rotations you might be interested in exploiting the fact that your students' smartphones are equipped with inertial navigation units (IMUs). Daniel Kawano and Prithvi Akella have harnessed the data from the IMU using the Matlab mobile app and used this data to determine the motion of a smart phone:
