Once in while, a new idea clobbers the brains of physicists and mathematicians. Suddenly, they are forced to look at the universe in new and sometimes counter-intuitive ways. Relativity. Quantum physics. Game theory. Chaos theory.
Abstruse stuff like that isn’t just parlor entertainment for members of Mensa. It has practical applications. Nuclear energy. Space travel. Computers. Even if we don’t get binomial distribution and math equations look to us like the number and letter stickers that my son has randomly plastered on his bedroom door, we should pay attention. Physics explains strange phenomena. Math orders what seems chaotic.
In the 1960’s, a French mathematician named René Thom came up with a way of understanding and describing sudden change. It was a breakthrough because ordinary math presumes that things are fixed and solid like number lines, triangles and cubes. Even the math of motion, calculus, conceives of moving bodies following smooth curves. Throw a stone or fire a rocket into the air and it follows a predictable and elegant path up and back down.
But not everything that happens is so smooth and elegant. The car ahead of you brakes sharply. A corn kernel in a pan of hot oil suddenly pops open. An old wall cracks. Such events may seem unpredictable, measurable only as probabilities. But every sudden change occurs in a particular moment. Think of a dome with a marble perfectly balanced on its apex. That marble isn’t going to stay there for long. At a certain moment, the marble will suddenly start to roll in one direction or another. Wouldn’t it be nifty to know when that moment will occur?
Okay, maybe knowing the precise second when a marble will begin to roll off a dome isn’t all that exciting. But what if math could tell us ahead of time when an airplane engine will fail, the day on which a depressed individual will commit suicide, or when prisoners will riot, or when a government will go to war?
René Thom came up with math which might predict such sudden changes, which he called catastrophes. His insights stirred hope that math could predict the previously unpredictable even in soft-science realms such as biology, psychology and social science. Catastrophe theory, it was thought, might illuminate things as diverse as animals’ territoriality, corporate decisions to raise prices, and humans’ behavior in paying taxes.
The key was Thom’s application of topology which, in plain English, considers what happens to invariant points when the set of which they are a part bends or stretches around that point. According to Thom, there are seven types of unstable curves, simple or three-dimensional, that show how a point will move “suddenly”—but predictably—according to how various forces are warping around it.
The seven types of unstable curves Thom named fold, cusp, swallowtail, butterfly, hyperbolic umbilic, elliptic umbilic, and parabolic umbilic. Don’t stress. There won’t be a quiz. Just have a look at this cusp catastrophe diagram that predicts when a tax scofflaw will suddenly decide to pay his or her taxes:
What you see above is that the space around a point (“A”) can bend and fold as different pressures effect it. When the fold becomes extreme enough, point “A” suddenly leaps from one spot to another. Point “A”, the tax scofflaw, in a startling instant becomes Point “B”, a dutiful taxpayer.
What Thom showed was that such behavior is not random, meaning that it will either happen or not. It will happen, math proves it, but to you and me the change that happens will look sudden and without immediate cause.
So, what has all of that to do with characters in fiction? Well, consider this: characters change. But how? When we speak of character arcs, we are—literally—using the old-school terminology and thinking of calculus, which is to say the presumption that change is a slow and smooth process. It isn’t. Not always.
If you have ever had trouble writing a scene, hacking at it over and over, trying this and that, tweaking to no avail, and then suddenly have muttered aloud, “Ah, fuck it”, and hit delete…well, then you know what I’m talking about. A sheet of paper crumpled and tossed into the waste basket is, math-wise, a catastrophe. Sudden. Violent. Without warning. However, it is the product of conflicting forces in your head curving around you to extremes and…BOOM! You hit delete. What forces might those be? Lousy draft tolerance versus looming deadline pressure? Whatever those forces are, you are going to change certainly and suddenly.
So it is with characters.
When they arrest our attention, changes in characters arrive without apparent warning. They are sudden. They are extreme. A character who behaves in one way all at once behaves in another. If forces acting upon that character are present and convincing, though, then as readers we don’t think, “Huh?”, but rather “Wow!”
Erika Johansen’s YA fantasy The Queen of the Tearling sets in motion the story of princess Kelsea Raleigh Glynn, who is reared in hiding in a forest by two mentors until her nineteenth birthday, when a company of soldiers called the Queens Guard arrives to escort her to her throne. However, her emergence from hiding is not welcomed by all. The kingdom of Tear’s regent, her vile and obsequious uncle, wants her dead in order to preserve the status quo, in particular Tear’s subjugation by its powerful neighboring Kingdom, Mort, and Mort’s evil queen. (Get it? “Tear”? “Mort”?)
The journey to her country’s capital is fearsome, with the traveling party spied upon by hawks and trailed by ninja-like assassins called Caden, and briefly Kelsea’s capture by a legendary (though perhaps patriotic) masked brigand named The Fetch. Kelsea is not brave, nor strong. She is terrified for her life and burdened by her heritage. (Her mother was a weak queen.) However, thanks to the captain of her guards, Mace, she finally arrives at the capital…on the day on which Tear’s annual tribute to Mort, a shipment of two hundred and fifty people, including children, chosen by lottery are being loaded into stout cages to be transported to Mort as slaves.
Up to this point Kelsea has been a plain-faced and fearful girl, utterly dependent on her guards for her survival. At this moment, though, she is called upon to become a queen and claim her birthright before her people. She obtains Mace’s pledge that he will defend her to the death, then asks him a question:
“What are those cages made of, Larazrus?”
“Mort iron.”
“But the wheels and undercarriage are wood.”
“Tearling oak, Lady. What are you getting at?”
Staring down at the table full of blue-clad officials in front of the Keep, Kelsea took a deep breath. This was her last moment to be anonymous. Everything was about to change. “The cages. After we empty them, we’re going to set them on fire.”
Kelsea’s transformation into The Queen of Tear is all the more dramatic for being, apparently, sudden. But actually, forces have been acting upon her all along. On the one hand she is a young woman of nineteen, raised in isolation. The reality of Tear is, to her, new and dangerous. On the other hand, her education by her mentors was to prepare her to rule. Her guards regard her with pessimism, but also with hope. The day of the tribute itself is an unbearable sight of weeping mothers and heartless enforcers. Fear and courage war within Kelsea and—BOOM—courage wins.
The word catastrophe carries an implication of disaster, destruction and defeat, but in fact René Thom showed us that catastrophe is only an instant shift from one place to another; in terms of character development, a “sudden” transformation from one state of being to another.
Let’s make this practical:
- What is the greatest change your protagonist must make? Who and what forces your protagonist to stay the same? Who and what urges your protagonist to change? Build up both forces. Set them in irreconcilable opposition to each other.
- What’s the greatest risk of change? Turn that risk from a possibility into a certainty.
- What makes staying the same impossible? What makes the status quo a kind of living death?
- What is the most dangerous—and important—moment for your protagonist to say, “Ah, fuck it!” What will your protagonist do at the moment that is fearful and irrevocable? Who will be terrified because of that act? Who will cheer?
Catastrophe theory shows us that change can be sudden, yet it is inevitable. It must happen and when it does it surprises us with the force of our hope, and lifts us with the buoyancy of its drama. If as a writer your process depends on random lightning bolts of inspiration that’s fine, but why not plan character catastrophes and bring them about?
See, math isn’t so hard, is it?
What change might your protagonist go through, and what opposing forces can push your protagonist to a “sudden” change?

Don, this was marvelous! I finally understand some of the sudden changes in my characters. I thought of it as the straw that breaks the camel’s back. Tipping point. Jim’s mirror moment is one such moment when the character sees the truth clearly and has to make a choice.
You’re a wonderful teacher. Thank you and God bless you.
Thanks, Vijaya, have a wonderful holiday season.
Wow, that diagram and explanation is REALLY helpful – both as a writer, and well, as a human.
Thanks, Donald. Yet another post full of ah-HAH insight.
Oh, and who else thinks “Catastrophe Theory” is a killer book title?
Actually, I learned all about this math from a book called, “Catastrophe Theory: The Revolutionary New Way of Understanding How Things Change” by Alexander Woodcock and Monte Davis, published by E.P. Dutton, 1978.
Hey Don – Of course the timing of this post, as well as the subject matter, could only bring me to think of one thing… Well, one person. Uncle Felix, in Christmas in Connecticut (played brilliantly by Hungarian actor S.Z. Sakall).
Uncle Felix is such a vital character in that movie, not just as the comic relief and a pseudo-parent figure to Barbara Stanwyck’s character, Elizabeth Lane. He’s a mentor-figure, and a background manipulator of the outcome. Early on he learns the word “catastrophe” which he pronounces, cat-oh-STROFF! And always at the moments when things flip, just as you describe. But Felix is also brilliant in that he understands the cat-oh-STROFF moments are necessary. He sees beyond them, always seeking a “hunky-dunky” outcome. (There’s another brilliant moment, a perfect demonstration of catastrophe, that involves Elizabeth and her stuffed-shirt fiance’s glass figurine – it’s your “aw, fuck it!” moment, and makes me laugh every damn time).
Uncle Felix aside (in the kitchen, as it were), this is really useful stuff. Throughout reading your piece I was jotting notes about Vahldan’s eventual catastrophe in book three – a moment of flipping which I have always been building up, but never recognized it for what it is, or for its potential to be a “wow” instead of a “huh.”
Thanks for the new perspective. Adding The Queen of Tearling to my TBR list. Hoping everything is hunky-dunky (with an absence of cat-oh-STROFF’s) for you and yours this holiday season.
Vaughn, love your comment. Cat-oh-STROFF cracks me up. The correlation to my maiden name is unbelievably fitting… Herm-e-STROFF will forever be joined with cat-oh-STROFF.
Thank you for gifting me with a smile this morning.
I am from the Nutmeg State, yet have never seen “Christmas in Connecticut”! Must watch!
I shall evermore and henceforth pronounce it cat-oh-STROFF!!
Am also earmarking this article for future reference!! Love the mind bending physics-y stuff, here, Don.
Happy Happy Merry Merry to you all.
Interesting connections, Don! Sometimes we choose change and sometimes it is thrust upon us. My Gilded Age WIP MC is a young woman from a rural southern background who accepts a position in the winter home of a wealthy northern industrialist. The cultural clash alone would be enough to bring about change within her, but certain tragic events force her into a better understanding of the world and human nature. She will never again be able to settle comfortably into her old life in the isolated, rural place of her childhood.
Sounds like a great story, Linda.
As always a teachable moment for me, when I think back over my novel to find these points of change. I also had my own personal experience recently, when at 10:00 pm in Southern California, the phone rang to tell us to evacuate because of the Woolsey fire. I had smelled smoke and had begun to collect things to pack–MY COMPUTER, when the call meant RACE, RUN–which leads the brain to panic and the inability to think. Rereading my novel and it’s catastrophic points–I now have an immediate personal reaction to see if my character’s actions ring true. Thanks for your post. Our house did not burn–but experience fuels more writing fires.
Whoa! So glad to hear your house is safe, even if its occupants were rattled.
Good morning, Don. This post earns a cuppa, if for no other reason than after reading through math and quantum physics, I needed another jolt of caffeine. 😁
“Seven types of unstable curves… fold, cusp, swallowtail, butterfly, hyperbolic umbilic, elliptic umbilic, and parabolic umbilic. Don’t stress. There won’t be a quiz. Just have a look at this cusp catastrophe diagram that predicts when a tax scofflaw will suddenly decide to pay his or her taxes:” (so glad there won’t be a quiz)
The imagery of each is so fascinating. The diagram of the cusp makes immediate sense, however, I’m intrigued by the possibilities of the others. I mean, wow, an elliptic umbilic?
Thanks for taking my brain beyond the current *oh fuck it* scene and giving me a new way to approach creating tension within character arc. I rather think my protagonist is on a jagged course, and possibly I’ve been attempting to keep her in a smoother, more controlled arc. You may have opened up and revealed my problem.
Thanks, Don. Merry Christmas to you and your lovely family.
Thanks for the coffee! And yes, a smooth and controlled arc is not necessarily a dramatic one. Mess it up!
Wow! I hadn’t heard of that theory.
I write intuitively, but concrete input like this helps. Every so often I second guess myself. Okay, a lot more often than that, but this theory shows that with the right pressure and circumstance, a character’s response could give the reader shivers. It’s nice to shock them once in a while.
Thanks for the insight!
…and hopefully shock us too, in a good way.
I loved this post, Don. What especially intrigues me is the idea of trying to show the forces of change bubbling away beneath the surface of a character until we get the seemingly unpredictable shift/catastrophe. Not sure how to do that, but your prompts will definitely help. It must mean that I need to show both the outside forces putting pressure on the character and the stirrings of transformation prodding her from within.
“It must mean that I need to show both the outside forces putting pressure on the character and the stirrings of transformation prodding her from within.”
Yes, exactly. A catastrophe (“sudden” change) doesn’t actually come out of the blue. Opposing forces must be at work, putting on pressure until…BOOM.
As a left-brained scientist, I often struggle with the right-brain aspects of writing fiction. This post was right up my alley — bring on the 3-D figures! A very insightful look at the way people–and characters–respond to mounting pressures. Many thanks!
