Questionable Content

Questionable Content 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 Questionable Content rather than just read about it. In short: Questionable Content (sometimes abbreviated as QC) is a slice-of-life webcomic written and illustrated by Jeph Jacques. It was launched in August 2003 and reached its 5,000th comic in March 2023.

Key takeaways

Questionable Content belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Questionable Content to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

Questionable Content (sometimes abbreviated as QC) is a slice-of-life webcomic written and illustrated by Jeph Jacques. It was launched in August 2003 and reached its 5,000th comic in March 2023. The plot originally centered on Marten Reed, an indie rock fan; his anthropomorphized personal computer Pintsize; and his roommate, Faye Whitaker. Over time Jacques has added a supporting cast of characters that includes employees of the local coffee shop, neighbors, and androids. QC's storytelling style combines romantic melodrama, situational comedy, and sexual humor, while considering questions of relationships, sexuality, dealing with emotional trauma, and artificial intelligence and futurism. After the comic's website was hacked and became unavailable in late April or early May of 2026, Jacques redirected that address to his own website. By late June of that year, questionablecontent.net was back online, but not yet updated with the installments of the comic Jacques had been posting to jephjacques.com following the hack.

Background

In 2003, Jacques worked at a local newspaper in Easthampton, Massachusetts answering telephones. According to Jacques, the large amount of free time and access to the Internet led him to read webcomics "as something to do". Jacques stated, "I've always been really interested in music, and indie rock specifically, and I never saw any other comics that dealt with that aspect of our culture. I felt like there was a niche there that would work." Jacques posted the first QC on August 1, 2003. Jacques makes his living from QC merchandising, advertising and donations. By 2004, Jacques could support himself and his then-partner based on income from merchandise and advertising sales. Merchandise has included designing T-shirts for the characters in the comic to wear, then selling real T-shirts of the same design. The comic is also supported by donors through Patreon. Jacques promoted the comic in a number of ways including joining the webcomic collective Dayfree Press for some time, and starting a fake feud with Sam Logan, the creator of Sam and Fuzzy, trading insults while linking to each other's comic. QC has also featured guest comics, often in exchange for Jacques writing a guest comic for the creator or for cross-promotion.

Publication Questionable Content was originally updated twice a week, and was later bumped to three strips a week. In September 2004, Jacques left his day job to begin updating Monday through Friday. According to Jacques in 2008, at one point he would have sought newspaper syndication for Questionable Content, but the thought no longer appealed to him because he does not want to surrender editorial freedom. The webcomic has been published in physical books; as of 2023, six volumes have been released, covering strips 1–1799. The first print collection features some of the earliest strips redrawn in Jacques art style at the time of the book; Jacques said this was because he did not have high-resolution copies of some old strips.

Style Both the methods of storytelling and the artistic style of the strip have changed considerably since its inception. Originally, Jacques intended the strip to be about "a depressed lonely guy and his robot", but the introduction of the female character Faye led to an increase in Jacques' ideas for the strip. Gradually, he decided he wanted to stop making indie rock jokes and focus more on the relationships between the characters, which had "always been the most fun and interesting part." Jacques spoke on the evolution of his art in an interview at ComixTalk in March 2006:

The art is constantly changing, as anybody who reads the comic for more than two weeks could probably tell you. I'm always trying different things with the artwork — it's been a goal from day one to continually improve my drawing ability, and I think it's finally beginning to get to the point where I'm halfway decent at it. It's basically survival of the fittest — changes that I think fit in with the overall look I'm going for stick around and get refined, and changes that do not fit in get phased out, sometimes in the course of three or four strips, sometimes over a much longer span of time. I'm trying to get better at using different "camera angles" in each panel and doing more involved backgrounds, both of which are really just a matter of being patient and taking my time with the artwork. There's still tons of room for improvement, and always will be, but I think I'm at least making progress. In strip #1040 in 2007, Jacques said that he used a Wacom Cintiq graphics tablet to draw his strips. In 2021, he tweeted that his software had been mainly Clip Studio Paint "for years now," and that he only used Photoshop for final layout and some image editing In 2007, he cited Bill Watterson (Calvin and Hobbes) and the webcomic Scary Go Round as his main influences.

Worked examples

Example 1 — a first encounter with Questionable Content

Start with the simplest possible case. Write down what Questionable Content 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 Questionable Content 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 Questionable Content 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 Questionable Content

In research: Questionable Content 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 Questionable Content 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: Questionable Content is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2000s webcomics, 2003 webcomic debuts, 2010s webcomics, so understanding it makes those chapters shorter.
In everyday life: Look for Questionable Content 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.
