A good collection of short stories, but the 'commentary' included is incredibly brief; if you've read these stories elsewhere, or own these in another collection, you'll find nothing new here.

The stories themselves, of course, are classic Clarke and well worth reading, here or anywhere else. ( )

The Sentinel collects nine pieces of Arthur C. Clarke's short fiction, with an author's introduction. These represent earlier work, since the 1972 story "A Meeting with Medusa" was Clarke's last, after which his fiction consisted entirely of novels (237). Each individual story is also supplied with a brief introduction by Clarke circa 1983.

Several of these stories are notable as having eventually contributed to novels by Clarke. The eponymous "The Sentinel" was the germ of 2001: A Space Odyssey. "Guardian Angel" was the basis of the first part of Childhood's End. "A Meeting with Medusa" contributed premises to 2010: Odyssey Two.

Despite some later incorporation into larger works, these stories do not generally presume a shared narrative continuity or "future history." Clarke was distinctive for his emphasis on scientifically plausible "hard" science fiction, to the point where composing a story could require "twenty or thirty pages of orbital calculations" (153). As a result, his relatively near-future stories of space exploration written over four decades had to change in order to align with the real-world developments of astronautical knowledge.

Clarke tended to err on the optimistic side. It was a little sad to read him writing in 1951 about a series of manned lunar surface explorations in 1996 which most certainly did not come to pass (139). Generally he avoids specific dates in these stories, though.

The story that was most interesting to me was "Breaking Strain," something of a psychological sketch regarding two men on a spaceship reduced to life support resources for one. It had a passing literary reference--somewhat anomalous among these pieces--to Cabell's Jurgen. Another story where there was a curious real-world reference was "Refugee," which painted a rather flattering picture of the British monarchy.

My copy of the book is a Barnes & Noble reprint of the Byron Preiss Visual Publications collection. It includes attractive and apt illustrations by Lebbeus Woods in black and white--roughly one full-page drawing per story (and in one case a two-page spread).

Historia que inspiró 2001 UNA ODISEA ESPACIAL del Director Stanley Kubrick ( )

A group of classic sci-fi stories told by a master storyteller. He brings us to our own world again and again, while also venturing to Jupiter, the Moon, and Jupiter again. He describes solar-powered yacht races to the Moon and back, provides us with a glimpse of ourselves millions of years hence when Sol becomes a supernova, and plant the seeds for what becomes Childhood's End and . It is a look into the "what could be" that is the best of science fiction.

For me, and the reason I gave it a 3* rating, is the super explanation of science that is now for me only mildly interesting. I can see where science geeks took ideas like this and ran with them; I'd definitely like to see the interplanetary yacht races done by giant kites! And Clarke does give some good human viewpoints that are burgeoning for the time in which he wrote. But like some science fiction fans for whom fantasy is not their thing, I think I'm more of a fantasy fan for whom science is interesting but not an important part of the story. ( )

Stories I have not read since I was a teenager. Clarke is one of my favorite scifi authors. ( )
