Glenn frowned, hmm. How could she answer this question, "I think it's important to remember history of things, maybe one day other technology will stop working but there will always be the sun, well, for millions of years to come anyway. But you'll still have the sun dial to roughly tell the time." Those were her two cents anyway, she couldn't think what it could be used for apart from that, but then again, maybe the Professor would tell them that later. |
