Imagine taking the entire text of “Moby Dick,” a novel published in 1851, and arranging it into a giant rectangle. You might start noticing some strange patterns, like words that seem to predict important historical events. Does this mean that Herman Melville, the author, was secretly predicting the future? The answer is no, and we can understand why through a mathematical concept called Ramsey theory. This theory helps explain why we see shapes in the stars and why, in a large group of people, at least two will share something in common, like the number of hairs on their head. It also sheds light on why we can find patterns in almost any text.
So, what exactly is Ramsey theory? In simple terms, it suggests that if you have enough elements in a set or structure, some interesting pattern is bound to appear. A classic example of Ramsey theory is the Party Problem. Imagine you have at least six people at a party. Without knowing anything else about them, you can be sure that some group of three people either all know each other or have never met before. You can visualize this by drawing a graph where each point represents a person and a line between two points indicates that those two people know each other. Each pair of people has two possibilities: they either know each other or they don’t.
Six is the smallest number of guests needed to guarantee this pattern. Ramsey theory assures us that such a minimum number exists for certain patterns, but it doesn’t provide an easy way to find it. As the number of guests increases, the number of possible combinations becomes overwhelming. For instance, if you want to find the minimum size of a party where there’s a group of five people who all know each other or all don’t, it’s tough to figure out because of the vast number of possibilities. A party with 48 guests has so many possible configurations that it exceeds the number of atoms in the universe. Even with computers, the best estimate for this problem is between 43 and 49 guests.
This demonstrates that specific patterns, which might seem unlikely, can emerge from a relatively small set. With a very large set, the possibilities are nearly endless. For example, any four stars that don’t form a straight line will create some kind of quadrilateral shape. When you consider the thousands of stars visible in the night sky, it’s not surprising that we can find familiar shapes and even creatures if we look for them.
So, what are the chances of a text hiding a prophecy? When you consider the number of letters, the variety of possible related words, and their abbreviations and alternate spellings, the chances are quite high. You can try it yourself: take a favorite text, arrange the letters in a grid, and see what you can find. The mathematician T.S. Motzkin once said that while disorder is more likely in general, complete disorder is impossible. The vastness of the universe ensures that some random elements will fall into specific arrangements, and because humans have evolved to notice patterns and signals among noise, we often find intentional meaning where there may not be any. So, while hidden messages can be intriguing, their true origin is often our own minds.
Draw a graph with six points, each representing a person at a party. Connect the points with lines to represent whether they know each other. Experiment with different configurations to see if you can find a group of three people who all know each other or who have never met. This will help you understand the Party Problem and the basics of Ramsey theory.
Go outside on a clear night and observe the stars. Try to identify existing constellations and then create your own by connecting stars to form new shapes or patterns. This activity will help you appreciate how humans find patterns in the vastness of space, similar to how we see shapes in the stars.
Select a passage from a book or a favorite text and arrange the letters in a grid. Look for words or patterns that emerge. Discuss with classmates whether these patterns seem intentional or random, and relate this to the concept of finding hidden messages in texts.
Using a computer program or a large sheet of paper, simulate a party with 48 guests. Try to determine if there is a group of five people who all know each other or all don’t. Discuss the challenges and insights gained from attempting to solve this complex problem, and relate it to the difficulty of finding patterns in large sets.
Engage in a classroom debate about whether patterns we find in texts, stars, or other large sets are truly significant or simply perceived due to our tendency to find order in chaos. Use examples from Ramsey theory and the article to support your arguments.

If you line up the entire text of “Moby Dick,” published in 1851, into a giant rectangle, you may notice some peculiar patterns, such as words that seem to predict significant historical events. So, was Herman Melville a secret prophet? The answer is no, and we understand this thanks to a mathematical principle called Ramsey theory. This principle explains why we can find geometric shapes in the night sky and why we can know that at least two people in a large group have something in common, such as the same number of hairs on their head. It also explains why patterns can be found in just about any text.
So, what is Ramsey theory? Simply put, it states that given enough elements in a set or structure, some interesting pattern among them is guaranteed to emerge. A classic illustration of Ramsey theory is known as the Party Problem. Suppose there are at least six people at a party. We can say for sure that some group of three of them either all know each other or have never met before, without knowing anything else about them. We can demonstrate this by graphing all the possibilities, where each point represents a person and a line indicates that a pair knows each other. Each pair has two possibilities: they either know each other or they don’t.
Six is the minimum number of guests where this property is guaranteed. Ramsey theory provides a guarantee that such a minimum number exists for certain patterns, but it doesn’t give an easy way to find it. As the total number of guests increases, the combinations become overwhelming. For example, if you want to find the minimum size of a party where there’s a group of five people who all know each other or all don’t, the answer is difficult to determine through exhaustive search due to the sheer volume of possibilities. A party with 48 guests has an astronomical number of possible configurations, far exceeding the number of atoms in the universe. Even with computers, the best estimate for this question is between 43 and 49 guests.
This illustrates that specific patterns with seemingly low odds can emerge from a relatively small set. With a very large set, the possibilities are nearly endless. Any four stars where no three lie in a straight line will form some quadrilateral shape. When expanded to the thousands of stars visible in the sky, it’s not surprising that we can find familiar shapes and even creatures if we look for them.
So, what are the chances of a text concealing a prophecy? When you consider the number of letters, the variety of possible related words, and their abbreviations and alternate spellings, the chances are quite high. You can try it yourself: pick a favorite text, arrange the letters in a grid, and see what you can find. The mathematician T.S. Motzkin once remarked that while disorder is more probable in general, complete disorder is impossible. The vastness of the universe ensures that some random elements will fall into specific arrangements, and because we evolved to notice patterns and signals among noise, we are often tempted to find intentional meaning where there may not be any. Thus, while we may be fascinated by hidden messages in various forms, their true origin is often our own minds.

This version maintains the core ideas while ensuring clarity and coherence.
Mathematics – The abstract science of number, quantity, and space, either as abstract concepts (pure mathematics), or as applied to other disciplines such as physics and engineering (applied mathematics). – In Grade 12, students often explore advanced topics in mathematics, such as calculus and linear algebra, to prepare for university-level courses.
Literature – Written works, especially those considered of superior or lasting artistic merit. – The study of literature in Grade 12 often includes analyzing complex themes and narratives in classic and contemporary novels.
Patterns – Repeated or recurring sequences or designs, often used to identify trends or make predictions in mathematics and literature. – In mathematics, recognizing patterns can help solve complex problems, while in literature, patterns in themes or motifs can reveal deeper meanings in a text.
Theory – A supposition or a system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained. – In literature, literary theory provides frameworks for interpreting texts, while in mathematics, number theory explores properties and relationships of numbers.
Guests – Individuals who are invited to participate or contribute to a particular event or discussion, often bringing new perspectives or insights. – In a literature seminar, guest speakers may include authors or scholars who provide deeper insights into the texts being studied.
Text – A written or printed work, regarded in terms of its content rather than its physical form. – Analyzing a text in literature involves examining its themes, characters, and stylistic elements to understand its meaning and impact.
Universe – All existing matter and space considered as a whole; the cosmos, often used metaphorically in literature to describe a complete or self-contained world. – In literature, an author may create a fictional universe with its own rules and logic, immersing readers in a unique narrative experience.
Messages – Ideas or themes conveyed through a medium, such as a text or mathematical proof, intended to communicate a particular point or insight. – In literature, the messages of a novel can reflect societal issues or personal struggles, while in mathematics, a theorem’s proof conveys a logical message about relationships between numbers.
Ramsey – Referring to Ramsey theory, a branch of mathematics that studies conditions under which order must appear. – Ramsey theory explores how complete disorder is impossible in large systems, providing insights into patterns and structures in mathematics.
Probability – The measure of the likelihood that an event will occur, often expressed as a number between 0 and 1. – In Grade 12 mathematics, students learn about probability to understand and predict outcomes in various scenarios, from simple events to complex systems.
