Infrared cameras

I brought a handheld IR camera to class in E2 just to see if it would stir up any interest. The most common types of reactions were "wow, that's cool" and "how much does it cost? I want one". Replies: "Yes, I know!" and "About $1000".

Charles Xie at Concord Consortium has proposed a set of labs using IR cameras in school:

I think the idea of being able to "see" thermal energy or heat flow fits well with the perspective of energy as a quasi-material substance, as applied in the energy courses.

Example clips:

  1. A few days ago Wendy was fondly reminiscing about the infrared camera that Adam had used in E1, and the group began searching for infrared photography (is that the right word) of whatever scenario they were working on at the time...I can direct you to the video if you'd like.

  2. Thanks, please point me to Wendy's reminiscences!

    We have called it IR imaging (and reserved photographs for regular photos of our lab set-up corresponding to the IR images).

    E1 followers: Have they been using IR camera images this year?
