VULCANOLOGY: "Most people don't think of Iceland as a suitable first choice for a vacation. But it's one of the places I personally prefer when I wish to see volcanoes in action. Either Iceland or Hawaii".

ASTRONOMY: "The third Tuesday of every month is Observatory night in Cambridge, Massachusetts, when under a thirty-foot bubble of copper in the middle of the city visitors can find the fifteen-inch refractor that was once the biggest and best telescope in the United States -- the 'Great Refractor.'"

HYDROLOGY: "If you happen to be in Chengdu, it's worth the trip to visit the Dujingyan Irrigation System. It's not a marvel of twentieth-century technology; it's much older than that -- 2,200 years older, to be exact".

TECHNOLOGY: "To get a good look at the complexity that lies under a major city, visit Consolidated Edison's little museum on the corner of East 14th Street and Third Avenue in New York. It's a mole's eye view of what's hidden from sight under that intersection".

These adventures and dozens more await you in Frederik Pohl's exploration of his lifelong love affair with science. Describing science destinations and museums around the world, Pohl reveals how anyone can join in the chase.
