<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>Oh absolutely. In addition to the other things, he was also an avid diving enthusiast. He gave two reasons: #1, it was the closest he was likely to get to weightlessness, and #2, underwater his physical limitations (due to polio) were not so bothersome. His photographs of the Great Barrier Reef have been credited partly with popularizing the spot with amateur divers.He was also active in amateur rocketry and did a great deal for popularization of science. </DIV></p><p>Don't foeget he also was involved with the first marine archaeological disovery in the Indian Ocean, a wreck dating from the time of the Great Mogul, carrying more than a tonne of silver coin. </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>On the flip side, he also tended to get a little too much into pseudoscience. For this, one could compare him to Sir Arthur Conan Doyle, who was also a little too credulous on certain topics. Clarke was particularly a bit of a Hoagland, lambasting NASA for not taking seriously his opinion of the Europan linea or Martian lava tubes. (He believed both to be artificial.)<br />Posted by CalliArcale</DIV></p><p>I don't think this is entirely fair. He was friends with Hoagland back when Hogaland was a sensible human being. But Sir Arthur did distance himself from Hoagland's wilder statments, although he did like the "glass worms" and contributed his own far out ideas (banyan trees"). But then Sir Arthur often wrote slightly tongue in cheek and never took himself too seriously. Unlike some others.</p><p>Saying that he lambasted NASA for not taking these ideas seriously is too strong. Nor, to my knowledge did he ever think that lines on Eurpoaa were artifical in real life, although he did write fiction about intelligent life there.</p><p>Lastly, in addition to his writings and comsats there is one other major impact that Sir Arthur made in daily life. In is RAF days he was involved with the development of radar controlled landing systems, along side such greats as Luis Alverez.</p><p> </p> <div class="Discussion_UserSignature"> <p><em>Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars</em> Arthur Clarke</p> </div>
