Lecture 1.4 - (S) Vision: How Light is Sensed by Neurons, Part 2

This module contains an introduction to the course as a whole (Video 1.1) and an exploration of how our eyes detect light and deduce the location light is coming from (Videos 1.2-1.6). You'll also learn about how scientists from Democritus to Alhazen to Kepler figured this out. The final video for the module involves an experiment to test what happens when special goggles turn the world upside down (Video 1.7). I'll show experiments frequently throughout this course -- they are how we know what we know. This module’s quiz is ungraded and available to both auditors and certificate students. Consider it a sample of the style of question in the quizzes for the remaining modules, and an opportunity to determine if you’d like to pursue a certificate for this course.
