Duncan Makenzie, the protagonist of Imperial Earth (1976) is a bisexual man, and sexual encounters with both genders are described. In fact, a romantic/sexual triangle between Duncan, his friend and sometimes lover Karl, and a girl called Calindy, is central to the plot.

According to the Wikipedia entry on Asimov, the short story is called "About Nothing" (1975), which first appeared on a postcard and then was included in the Winds of Change and other short stories collection. About Nothing By Isaac Asimov All of Earth waited for the small black hole to bring it to its end. It had been discovered by Professor ...

This is really more of a physics issue, see my answer on the physics stack exchange here--objects away from the ground in a rotating cylinder will still appear to be subject to gravity, their inertial paths will naturally cause them to come crashing to the inner surface of the cylinder (similarly, see this page for a short explanation of why someone jumping ...

Asimov vs Heinlein Asimov and Heinlein did have some disagreements, according to this article on io9: Primarily their conflict became a political disagreement, as Asimov revealed in his posthumous 1994 autobiography. and later on: Living longer than Heinlein allowed Asimov to have the last word in the debate, bashing the release of Heinlein ...

In Rendezvous With Rama (1973) two male crew members are in a polyamarous relationship with each other and a woman back on earth. But no one can predict where the lightning will strike, and years ago Mercer and Calvert had established an apparently stable liaison. That was common enough. Much more unusual was the fact that they also shared a wife back ...

The Ghost from the Grand Banks is a 1990 science fiction novel by British writer Arthur C. Clarke. The story deals with two groups, both of whom are attempting to raise one of the halves of the wreck of Titanic from the floor of the Atlantic Ocean in time for the sinking's centennial in 2012. The mathematician is Ada Craig, and the part with the mention of 1....

The justification for this is given several times over in the books, twice in 2010 alone:And because, in all the Galaxy, they had found nothing more precious than Mind, they encouraged its dawning everywhere. They became farmers in the fields of stars; they sowed, and sometimes they reaped.And sometimes, dispassionately, they had to weed.Life on Jupiter very ...

Got it! In December 2014, the National Air and Space Museum Archives at the Smithsonian National Air and Space Museum received Arthur C. Clarke papers collection from the Arthur C. Clarke Trust in Sri Lanka. Read about it here, here and here. I contacted the Smithsonian, and they kindly sent me a photocopy of the Dalai's Lama letter. The letter is short and ...

In From Narnia to a Space Odyssey: The War of Letters Between Arthur C. Clarke and C. S. Lewis, the first very short letter from Lewis to Clarke (December 7, 1943), Lewis is responding to Clarke's accusation that Lewis sees all SF as trashy space opera and that Lewis' portrait of Weston is colored by that. Lewis responds: I don't of course think that at any ...

tl;dr The manifold surrounding Shervane's universe is called an Alice handle. To simplify the explanation and ease visualization, imagine that our hero Shervane is a two-dimensional being who lives on a finite 2D surface, a circular region cut out of a plane. Viewed from above Shervane looks like the letter R as he moves around his world. Looking down we ...

In order to hover (approximately) in place over the surface of the rotating habitat, the helicopter does need to exert a force "upwards", i.e. towards the axis of rotation. This is because the habitat is rotating, which means that its surface is constantly moving around the axis. But the surface is also constantly being pulled towards the axis by ...

Life on Jupiter is in fact mentioned in the novel that the "2010" movie is based on: Bowman's avatar visits both Europa and Jupiter, and finds primitive (not intelligent) life forms in both places. The Monolith's controllers let him know that they consider it very unlikely for the gaseous lifeforms on Jupiter to ever achieve intelligence, but see that ...

You may be thinking of Clarke's 1968 short story Crusade (ISFDB). The story is set on a world without a sun, halfway between two galaxies. The world is covered with seas of liquid helium. The conditions permit superconductivity, which eventually evolves into a planetwide, computer-like intelligence. The intelligence decides it should explore the two nearby ...

2001: A Space Odyssey was written concurrently with the development of the film. This is covered in the Development section of the Wikipedia article, for example: Early drafts included a short prologue containing interviews with scientists about extraterrestrial life, voice-over narration (a feature in all of Kubrick's previous films), a stronger emphasis ...

I believe you are looking for the collection Tales of Ten Worlds (1962). The first story is "Let there be light" (1957). A character criticized the way that death rays in science fiction were visible to the human eye, saying that if visible light was deadly, humans couldn't live. The conversation had come around to death rays again, and some carping ...

Arthur Clarke did read Moby-Dick; in an interview with Studs Terkel, he said that the novel had a great impact on him. And I got interested in whales, partly because of this, and part because I suppose "Moby Dick" had a greater impact on me than any other novel I ever read. And I did a book called "The Deep Range", which is about whale ranching, whale ...

An author is not obliged to write only books who promote his own worldview and in my humble opinion many, if not most books of that kind turned out to be badly written. As we are in sci-fi and fantasy, we are reading books which describes things which are (at least currently) not part of our world or our worldviews, so we violate this idea constantly. A ...

Walter Curnow from 2010: Odyssey Two is described as being a "cheerfully well-adjusted polymorph" - i.e. happily bisexual.

If I'm not mistaken the cause is that the atmosphere in the cylinder will be rotating together with the inner surface of the cylinder (due to drag). Therefore even an air-born object will still have rotational velocity since it's dragged along with the air surrounding it.

I don't recall the refernce to Clarke's Third Law explicitly, but he actually used the substance of it. From http://tvtropes.org/pmwiki/pmwiki.php/Main/MagicFromTechnology: ... the Anacreonian civilisation is basically taken over by Salvor Hardin's new religion of science. Interestingly, this wasn't the original intention of the Foundation citizens (though ...

The answer already given touches on whether what an author writes, is the same as what an author believes. However, in the specific case of the Rama series, after the first book, it's not so much Arthur C. Clarke writing as it is Gentry Lee. Especially the last of the series, Rama Revealed, was written by Gentry Lee, with Arthur C. Clarke only consulting. ...

I've been unable to find any stories by Arthur C Clarke featuring matrioshka brains ... could you be thinking of Accelerando, which is by Charles Stross and not Arthur C Clarke (although it won the Arthur C Clarke award in 2006)? Quoting from its description on Wikipedia (emphasis mine): As events progress in Accelerando, the planets of the solar system are ...

As explained in this Wikipedia article, there are two versions of the Clarke short story "The Awakening". In the earlier one, first published in the fanzine Zenith in 1942 and reprinted in The Collected Stories of Arthur C. Clarke, the Master puts himself into suspended animation in the Himalayas. In the second, reprinted in Reach for Tomorrow (1956), a ...

The impression I got from the first book was that Raman engineering (as ours) required important systems to be fault-tolerant. The fact that triple modular redundancy was routine, I think, was meant to inspire awe as the kind of resources they could command, and the reliability of their constructions. I don't recall a obsession for threes besides ...

Clarke is likely placing Shastar in the Nile delta in present day Egypt, possibly near the city of Alexandria. The old Roman Road along the Mediterranean Coast of North Africa meets all the terms he referenced (see my marked up map below). It is approximately 1,000 miles long, runs closely along the sea, passing many areas which had early sea merchant ...

Yes, in The Songs of Distant Earth, pretty much everyone on it is, at least, bisexual. In it, Arthur C. Clark treats sexuality has something volatile, with people not belonging fully to one end of the scale (homo or hetero). The colony on the planet in which the story takes place (Thalassa), was founded with the aid of machines, one of which containing all ...
