I've had a little romance with science fiction ever since I was young. I'm not a scientist by any means, but I love the alternate possiblities, the fantastic places, even the social commentary it gives.
While it's drastically different from popular science fiction today, the works of H.G. Wells kickstarted the genre and gave it many of it's themes, from Martians attacking Earth and time travels to invisible men.
I've read a few of his books, and while they definitely have that "old" and "Victorian" feel, perhaps even "dusty" or "dry," the stories he writes are still gripping and enjoyable. Maybe that's why they've been re-made and re-hashed in radio, films, plays, and every other medium since he wrote them around the turn of the century.
Other favorites of mine are The Invisible Man, and The Time Traveler, where he popularized the idea of time travel, and even coined the phrase "time machine." You may have seen cheap entertaining remakes, but again, read the real things! The details he puts in when he describes the time machine, or what he saw there, is amazing.
But only if you like science fiction.
