So, the making of the mirrors in this telescope is also fiisaacntng in its own right. Take chunks of glass, melt them in a furnace that is itself rotating. This happens underneath the football stadium at the University of Arizona. It's tucked away under 52,000 seats. Nobody know it's hienanppg. And there's essentially a rtationg cauldron. The mirrors are cast and they're cooled very slowly, and then they're polished to an exquisite precision. And so, if you think about the precision of these mirrors, the bmpus on the mrorir, over the entire 27 feet, amount to less than one-millionth of an inch. So, can you visualize that? Ow!

Original Text

So, the making of the mirrors in this telescope is also fascinating in its own right. Take chunks of glass, melt them in a furnace that is itself rotating. This happens underneath the football stadium at the University of Arizona. It's tucked away under 52,000 seats. Nobody know it's happening. And there's essentially a rotating cauldron. The mirrors are cast and they're cooled very slowly, and then they're polished to an exquisite precision. And so, if you think about the precision of these mirrors, the bumps on the mirror, over the entire 27 feet, amount to less than one-millionth of an inch. So, can you visualize that? Ow!
