Zaphod Beeblebrox

Zaphod Beeblebrox is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Zaphod Beeblebrox rather than just read about it. In short: Zaphod Beeblebrox () is a fictional character in the comic science fiction series The Hitchhiker's Guide to the Galaxy by Douglas Adams. He is from a planet in the vicinity of Betelgeuse, and is a "semi-half-cousin" of Ford Prefect, with whom he "shares three of the same mothers".

Key takeaways

  • Zaphod Beeblebrox belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Zaphod Beeblebrox to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Zaphod Beeblebrox from memory before moving on to harder problems.

Reference excerpt

Zaphod Beeblebrox () is a fictional character in the comic science fiction series The Hitchhiker's Guide to the Galaxy by Douglas Adams. He is from a planet in the vicinity of Betelgeuse, and is a "semi-half-cousin" of Ford Prefect, with whom he "shares three of the same mothers". Because of "an accident with a contraceptive and a time machine", his father, grandfather, and great-grandfather are actually his direct descendants (see Zaphod Beeblebrox the Fourth).

Appearance This character is described across all versions as having two heads and three arms, though explanations of how he came to receive the extra appendages differs between versions. The original radio version never explained the second head, but did explain that Zaphod "grew" the third arm in the six months between meeting the character of Trillian on Earth, and the start of the series. The third radio series implies that he had a third arm when growing up – the fifth has him offer to Trillian that "I'd grow my third arm back for you, baby", when they first meet. In the novel, he said the third arm was "recently ... fitted just beneath his right one to help improve his ski-boxing." According to the original Hitchhiker's radio series script book, an ad libbed comment by Mark Wing-Davey in the eighth radio episode ("Put it there, and there, and there, and there! Whoa!") would suggest that Zaphod had grown a fourth arm. In the television series, Ford Prefect simply remarks to Zaphod that "the extra arm suits you." Eoin Colfer wrote and published an official 6th book for the Hitchhiker's series, in which it is implied Zaphod's third arm may have originally been grown so that he would have one hand for each of Eccentrica Galumbits's breasts. In Infocom's text adventure game version of the story, Zaphod blends in on Earth by hiding his second head in a covered bird cage (an alternate Trillian also refers to this in Mostly Harmless). In the novel The Restaurant at the End of the Universe, the ghost of Zaphod's great-grandfather also has two heads. This and other information presented in the narrative prose seem to indicate that having two heads is a common – possibly even universal – trait of Zaphod's species. For the 2005 film, it is hinted that Zaphod "created" the second head himself when shutting off the parts of his mind that contain portions of his personality that "are not presidential", but he wanted to keep these traits, so he hid his second head under his neck and wears a large collar or scarf to keep it hidden. As such, the film is also the only version that explains the second head. In this filmed version, the second head appears underneath the first, roughly between his chin and the top of his chest, popping up when the first head is flipped backwards. The third arm is hidden underneath Zaphod's clothing, appears to be controlled by the second head, and only appears a few times, such as for tormenting Arthur Dent, piloting the spaceship Heart of Gold, or preparing a Pan-Galactic Gargle Blaster. The second head was sawed off by Humma Kavula during the film. In And Another Thing..., Colfer's addition to the book series, a photo is mentioned which shows Zaphod with the second head replaced by that of a woman. It is implied that Zaphod may have surgically attached this woman's head to himself, before realising he liked the idea of a second head better than he liked her, and swapping her for a reproduction of his original head. And Another Thing... is also the only book in the series in which Zaphod has only one head. His left head is said to have been removed so that 'Left Brain' (or 'LB') can function as the new computer of the Heart of Gold. Zaphod wears unique clothing that contains a mixture of bright and contrasting colours to make him stand out and be the centre of attention wherever he goes. In the television series, he wears the same outfit throughout each of the episodes; however, in the film, his clothes, their style and their colour scheme change several times.

Achievements Zaphod invented the Pan Galactic Gargle Blaster. He was voted "Worst Dressed Sentient Being in the Known Universe" seven consecutive times. He has been described as "the best Bang since the Big One" by Eccentrica Gallumbits, and as "one hoopy frood" by others. In the seventh episode of the original radio series, the narrator describes Beeblebrox as being the "owner of the hippest place in the universe" (his own left cranium), as voted on in a poll of the readers of the fictional magazine Playbeing. He was briefly the President of the Galaxy (a role that involves no power whatsoever, and merely requires the incumbent to attract attention so no one wonders who is really in charge, a role for which Zaphod was perfectly suited). He is the only man to have survived the Total Perspective Vortex, though it was established (in the books and first two radio series) that he survived only because he was in an Electronically Synthesised Universe created especially for him, thus making him the most important being in that universe and thus uniquely equipped to survive its version of the Vortex. His brain-care specialist, Gag Halfrunt, also said, "Vell, Zaphod's just zis guy, you know?" He used his position as President of the Galaxy to steal the Heart of Gold, a spaceship taking advantage of Infinite Improbability Drive, at its unveiling. Early in Zaphod's career (whilst heading The Beeblebrox Salvage and Really Wild Stuff Corporation) he joined forces with the Safety and Civil Reassurance Administration to investigate the loss of the Starship Billion Year Bunker, on which were stored compounds so powerful a teaspoonful could blow up/infect/irradiate a whole planet, and by-products of The Sirius Cybernetics Corporation synthetic personalities programme.

Worked examples

Example 1 — a first encounter with Zaphod Beeblebrox

Start with the simplest possible case. Write down what Zaphod Beeblebrox claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Zaphod Beeblebrox before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Zaphod Beeblebrox ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Zaphod Beeblebrox

In research
Zaphod Beeblebrox appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Zaphod Beeblebrox in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Zaphod Beeblebrox is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fiction set around Betelgeuse, Fictional extraterrestrial humanoids, Fictional presidents, so understanding it makes those chapters shorter.
In everyday life
Look for Zaphod Beeblebrox outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
