From the Ted Talk by Kristin Poinar: What's hidden under the Greenland ice sheet?

Unscramble the Blue Letters

When was I was 21 years old, I had all this physics homework. Physics homework requires taking breaks, and Wikipedia was relatively new, so I took a lot of breaks there. I kept going back to the same articles, reading them again and again, on glaciers, Antarctica and Greenland. How cool would it be to visit these places and what would it take to do so? Well, here we are on a rpeeropsud Air Force cargo plane operated by NASA flying over the Greenland ice sehet. There's a lot to see here, but there's more that is hedidn, wiiatng to be uncovered. What the Wikipedia atelrics didn't tell me is that there's liquid water hidden inside the ice sheet, because we didn't know that yet.

Original Text

When was I was 21 years old, I had all this physics homework. Physics homework requires taking breaks, and Wikipedia was relatively new, so I took a lot of breaks there. I kept going back to the same articles, reading them again and again, on glaciers, Antarctica and Greenland. How cool would it be to visit these places and what would it take to do so? Well, here we are on a repurposed Air Force cargo plane operated by NASA flying over the Greenland ice sheet. There's a lot to see here, but there's more that is hidden, waiting to be uncovered. What the Wikipedia articles didn't tell me is that there's liquid water hidden inside the ice sheet, because we didn't know that yet.
