John Evans on 24 Jun 15"I enjoy some of the TED-Ed lessons so much that I have an alert on my phone that goes off whenever a new TED-Ed lesson is published. How X-Rays See Through Your Skin is the latest TED-Ed lesson. I found the lesson fascinating because it not only explained how modern x-rays and CT scans work, but it also explained some of the history of x-ray development."
