Workshop 2: Drag Races
Forces can help put objects into motion and can also bring moving objects to a stop. In this workshop, fifth-grade students explore the physics of motion using plastic cars with strings and washers attached to provide a pulling force. The students test the speed of the vehicles and explain what forces bring the vehicles to a stop, as the cars collide with and displace ba

21L.448J Darwin and Design (MIT)
In the Origin of Species (1859), Charles Darwin gave us a model for understanding how natural objects and systems can evidence design without positing a designer: how purpose and mechanism can exist without intelligent agency. Texts in this course deal with pre- and post-Darwinian treatment of this topic within literature and speculative thought since the eighteenth century. We will give some attention to the modern study of feedback mechanisms in artificial intelligence. Our reading will be in

What Neurology Can Tell Us about Human Nature - October 15, 2009
Studies of neurological patients can provide insight into the workings of the brain and suggest new treatments. The first section of the lecture will focus on phantom limbs as a key to understanding brain functions. We show that far from having fixed connections, even the basic “wiring ” of the brain is constantly being modified in response to changing sensory inputs. This has theoretical implications as well as practical implications for recovery of function from stroke, phantom pain, and
