Thirteenth Doctor

Thirteenth Doctor is a science 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 Thirteenth Doctor rather than just read about it. In short: The Thirteenth Doctor is an incarnation of the Doctor, the protagonist of the BBC's science fiction television series Doctor Who. She is played by Jodie Whittaker, the first woman to portray the character, in three series, five specials and a cameo in the fifteenth series.

Key takeaways

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

Reference excerpt

The Thirteenth Doctor is an incarnation of the Doctor, the protagonist of the BBC's science fiction television series Doctor Who. She is played by Jodie Whittaker, the first woman to portray the character, in three series, five specials and a cameo in the fifteenth series. As with previous incarnations of the Doctor, the character has also appeared in other Doctor Who spin-offs, both during and after the character's televised appearances. Within the series's narrative, the Doctor is a millennia-old, alien Time Lord from the planet Gallifrey, with somewhat unknown origins, who travels in time and space in their TARDIS, frequently with companions. At the end of life, the Doctor regenerates; as a result, the physical appearance and personality of the Doctor change. Whittaker's incarnation is a light-hearted adventurer with a passion for building things, placing a high value on friendships and striving for non-violent solutions. Preceded in regeneration by the Twelfth Doctor (Peter Capaldi), she is followed by the Fourteenth Doctor (David Tennant). This incarnation's first companions were a trio consisting of retired bus driver Graham O'Brien (Bradley Walsh), his dyspraxic step-grandson and part-time warehouse worker Ryan Sinclair (Tosin Cole), and probationary police officer Yasmin "Yaz" Khan (Mandip Gill), all of whom she met shortly after her regeneration. After Graham and Ryan leave, the Doctor and Yaz are joined by food bank volunteer Dan Lewis (John Bishop). She also had one-episode reunions with former companions Captain Jack Harkness (John Barrowman), Tegan Jovanka (Janet Fielding), and Ace (Sophie Aldred).

Casting In January 2016, Steven Moffat announced that he would leave the show after the tenth series; he was set to be replaced by new showrunner, Chris Chibnall. Peter Capaldi confirmed a year later that the tenth series would be his last as well. Following this news, several media reports and bookmakers had speculated as to who would replace Capaldi as the Thirteenth Doctor. Bookmakers' favourites included Ben Whishaw, Phoebe Waller-Bridge, Kris Marshall, and Tilda Swinton.

Casting a woman The concept of a female Doctor was first mentioned in 1981, when Tom Baker suggested his successor might be female, after announcing the end of his tenure as the Fourth Doctor. Producer, John Nathan-Turner, later discussed the possibility of casting a woman as the Sixth Doctor to replace the departing Peter Davison's Fifth Doctor, claiming it was feasible, but not something he was considering at the moment. In October 1986, during the transmission of Colin Baker's final season as the Sixth Doctor, series creator, Sydney Newman, wrote to BBC Controller, Michael Grade, with a suggestion that "at a later stage, Doctor Who should be metamorphosed into a woman". Dawn French, Joanna Lumley, and Frances de la Tour, were suggested by Newman in 1986 for the role, but were dismissed by the BBC. Lumley later appeared as a satirical version of the Thirteenth Doctor in the 1999 Comic Relief special, The Curse of Fatal Death. Arabella Weir also played an alternative Third Doctor in the Doctor Who Unbound Big Finish episode, Exile. Neither portrayal is typically considered to be within the show's main continuity. Producer, Jane Tranter, also considered casting Judi Dench as the Ninth Doctor. The concept of Time Lords changing sex upon regeneration was seeded throughout Moffat's tenure as showrunner. Just after regenerating, the Eleventh Doctor exclaims "I'm a girl?" In the 2011 episode, "The Doctor's Wife", the Doctor recalls a Time Lord acquaintance known as the Corsair, who had at least two female incarnations. In the 2013 short, "The Night of the Doctor", the Sisterhood of Karn offer a dying Eighth Doctor (Paul McGann) control over his inevitable regeneration, with "man or woman" being touted as possibilities. The first on-screen cross-gender regeneration was shown in the 2015 episode, "Hell Bent", in which a white male Gallifreyan general (Ken Bones) regenerates into a black woman (T'Nia Miller), who states that her previous incarnation was the only time she had been a man. The most notable Time Lord to have appeared in both male and female forms prior to Whittaker's casting is the Doctor's nemesis, the Master, portrayed from 2014 to 2017 by Scottish actress, Michelle Gomez. This version of the character was known as Missy, short for "Mistress". The tenth series finale, "World Enough and Time" / "The Doctor Falls", addresses cross-gender regeneration several times; the Doctor tells his companion Bill Potts (Pearl Mackie) that Missy was "his first man-crush", and adds that he is only "fairly sure" he himself was male at the time, although the remark may have been flippant. Two years prior to the announcement of Whittaker's casting, fans and scholars discussed the possibility of a female Doctor and analysed the benefits of such a regeneration.

Worked examples

Example 1 — a first encounter with Thirteenth Doctor

Start with the simplest possible case. Write down what Thirteenth Doctor claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Thirteenth Doctor 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 Thirteenth Doctor 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 Thirteenth Doctor

In research
Thirteenth Doctor appears in science 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 Thirteenth Doctor 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
Thirteenth Doctor is common in secondary-school and first-year university syllabi. It links to neighbouring topics Casting controversies in television, Doctor Who Doctors, Extraterrestrial characters in television, so understanding it makes those chapters shorter.
In everyday life
Look for Thirteenth Doctor 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.
