There are a variety of really great lectures called TED Talks. Go to http://www.ted.com/talks and look around for a lecture that relates to a topic discussed so far in our text - preferably related to the representation of knowledge. This might take some doing, if you can't find one that directly relates - find one that is close.
After you watch the video discuss how your text discusses the material covered in the Ted Talk?
Next, briefly discuss including 1) Why you picked that video, 2) What you expected to see, 3) What you actually saw and if you liked it or not, 4) What interested you the most?, and 5) What will you remember from the video.
Make a list of key terms and concepts you used in your post.
Let me know if you have any questions,
