The Man Who Knew Infinity (2015):The Biographical Drama That Pairs Mathematical Intuition With Discrimination at Cambridge

The Man Who Knew Infinity introduces students to Srinivasa Ramanujan, a mathematician whose ideas came to him through intuition rather than formal proof, and to the academic world at Cambridge that insisted every idea be proven before it could be believed. That clash between two different ways of arriving at the truth runs through the entire movie.

Based on the book by Robert Kanigel, the movie follows Ramanujan as he leaves a life of poverty in Madras, India, to study under Professor G. H. Hardy at Cambridge during the First World War. While Hardy works to help Ramanujan publish and prove his theories, Ramanujan faces racism and isolation in a culture that has little patience for an outsider's brilliance.

For a classroom, the movie gives students a real historical figure to study alongside questions about how different cultures value knowledge, how discrimination shaped Ramanujan's experience at Cambridge, and what it costs a person to pursue recognition far from home.

🔢 It centres a real mathematician whose ideas came from intuition. Ramanujan's mathematical insight worked differently to the formal, proof-based approach expected at Cambridge. Students see a genuine historical example of two different ways of arriving at mathematical truth coming into conflict.

🎓 It is set inside wartime Cambridge, with all the friction that implies. Ramanujan arrives at one of the world's most established academic institutions as an outsider with no formal training. The movie shows how that institution responds to someone who does not fit its existing mould.

⚖️ It addresses racism and discrimination directly through Ramanujan's experience. Ramanujan faces prejudice from peers and, in one scene, a racially motivated attack. The movie does not soften this, giving students a clear, specific example to discuss rather than an abstract idea of discrimination.

🤝 It explores a working relationship built on real disagreement. Ramanujan and Hardy approach mathematics from opposite directions, yet their collaboration produces real advances. Students see a model of two people working through genuine intellectual difference rather than simple agreement.

🌍 It shows the personal cost of leaving home to pursue recognition. Ramanujan leaves his wife and his culture behind to study in a country that does not make him welcome. The movie keeps that personal cost visible alongside his academic achievements.

⚠️ Things to be aware of:

• One scene shows Ramanujan being attacked and beaten by a group of soldiers because of his race.
• Racist comments and attitudes toward Ramanujan appear throughout the movie.
• Some non-graphic war imagery related to the First World War.
• Characters are shown smoking cigarettes and drinking wine at meals.
• Language is infrequent and mild, limited to words like hell, damn, and bloody.

📚 English Language Arts Teachers. The Man Who Knew Infinity suits ELA classes studying biography, narrative structure, or the relationship between a person's inner life and the historical events around them. The guide supports a range of writing tasks, from sequencing and synopsis writing through to a diary entry essay, with the comprehension questions available in two differentiated sets.

🗣️ ESL and ELL Teachers. The multiple choice comprehension set is designed to work well with ESL and ELL students, giving them an accessible way to follow a story that moves between India and wartime England.

🌐 Social Studies Teachers. The movie's setting in wartime Cambridge, and its direct treatment of racism and cultural displacement, make it relevant to Social Studies classes covering early twentieth century history, colonialism, or discrimination. The guide does not include dedicated Social Studies activities, but the comprehension questions and essay task give students a structured way to engage with these themes.

🎬 Substitute Teachers and Cover Lessons. The two sets of differentiated comprehension questions and clear part by part structure make this guide easy to hand to a substitute teacher to run with little preparation.

🏠 Homeschool Parents. The Man Who Knew Infinity makes for a rich home learning session with a teenager. Ramanujan's story raises real questions about ambition, recognition, and what it costs to pursue a gift no one around you understands, the kind of themes that open up genuine conversation between a parent and an older student. The critical thinking questions and essay task in Part 3 give that conversation a structured starting point.

📐 Math Teachers. Ramanujan's real life and intuitive approach to mathematics make this movie relevant to Math classes exploring the history of mathematics or different mathematical traditions. His work on number theory still underpins parts of modern cryptography. The guide does not include dedicated math activities, but the comprehension questions keep students accountable to the details of his work and its reception while watching.

🔭 STEM Teachers. Ramanujan's story puts mathematical intuition and the process of formal proof at the center of a biographical drama, giving STEM classes a way to discuss what rigorous thinking in a technical discipline looks like and what it costs. The guide's comprehension questions give students a structured framework for watching.

🌟 Supporting All Learners Movie guides can be a wonderfully calm fit for students with autism, learning difficulties, and mild to severe disabilities. The structured format gives every student a clear purpose during viewing, easing uncertainty and allowing them to engage at their own pace. If you teach in a special education or learning support setting, you may find this guide a gentle and practical resource. Find out more about why movies work for diverse learners.

Part 1: Comprehension Questions
Two differentiated sets of questions in chronological order, 30 full sentence questions and 30 multiple choice questions, the latter also noted as suitable for ESL and ELL students. Answer keys are included for both sets.

Part 2: Storyboard and Synopsis
Students create a nine scene storyboard illustrating pivotal events from the movie, with a short description explaining the main idea of each scene, then use their storyboard as a guide to write a synopsis of the movie.

Part 3: Critical Thinking and Essay
Three long answer critical thinking questions with example answers included, followed by an essay task in which students write a diary entry imagining Ramanujan's thoughts and feelings as he faces racial discrimination and a new culture upon arriving at Cambridge.
