A Beautiful Mind

A clever mathematician's mind starts to trick him — but his real story has an amazing true prize at the end.

Today: tell the story of the film A Beautiful Mind — a clever man whose own mind starts to trick him — learn what is true and what is not true, and learn to use who, which and that.
Before we begin — talk about it: Do you know someone very intelligent? Is it always easy to be very clever? Do you think illness can sometimes be invisible — something you cannot see from outside?

The words for today's story

These are the new words. Match each word (1–8) to its meaning (A–H). Say your answers out loud — "I think 1 is D" — then check.

Words

  1. a genius
  2. a university
  3. an illness
  4. a doctor
  5. imaginary
  6. a prize
  7. proud
  8. to recover

Meanings

  • A. not real; only in your mind
  • B. a person who treats sick people
  • C. an award given for something excellent
  • D. a person who is extremely intelligent
  • E. feeling pleased about something you or someone did
  • F. a sickness of the body or mind
  • G. to get better after being ill
  • H. a place where people study after school

1 = D (a genius) · 2 = H (a university) · 3 = F (an illness) · 4 = B (a doctor)

5 = A (imaginary) · 6 = C (a prize) · 7 = E (proud) · 8 = G (to recover)

Now talk — out loud

Before we watch:
  • Which words are about the mind? Which words are about being ill or getting better?
  • Use three of the words to guess: what do you think happens in this film?

The film, in three parts

Ron Howard's A Beautiful Mind (2001). Read each part. Then try the questions from memory, and talk about the last one. (There are spoilers — that is fine, we want to talk about it. This story is about a serious illness, so we talk about it carefully and with respect.)

Part 1 — A clever, strange young man

John is a very clever young man. He studies mathematics at a top university. He is strange with people, but brilliant with numbers. He wants to find one big, new idea. One evening, he watches his friends in a bar, and he has an idea about how people compete. Later, this idea will make him famous.

Years later, John is a teacher. He is married to Alicia, a clever student. A mysterious man called Parcher asks John to do secret work for the government: to find hidden messages inside newspapers. John tells no one, not even Alicia. He feels important and useful.

Quick check — answer from memory, then reveal:

1. What big idea does John have, watching his friends in the bar?

2. What secret job does Parcher give him?

1. He realises that if people think about what others will do, and do not all compete for the same thing, everyone can do better. This becomes a famous idea in mathematics.

2. Parcher asks him to find secret enemy messages hidden inside ordinary newspapers and magazines.

Talk about it:
  • John keeps his secret work hidden from his wife. Do you think it is ever right to keep a secret from someone you love, to protect them?

Part 2 — The frightening truth

John becomes more and more afraid. He is sure that dangerous men are chasing him. His strange behaviour frightens Alicia and puts their baby son in danger. Then comes a terrible shock: Charles, his good friend, and Parcher, the secret agent, are not real people. They exist only in John's mind.

Doctors say John has a serious mental illness called schizophrenia. He goes to hospital for treatment. Later, medicine helps stop the illness, but it also makes his mind slow and unclear. John and Alicia decide to stop the medicine — and the illness comes back, very badly.

Quick check — answer from memory, then reveal:

1. What shocking truth do John and Alicia learn about Charles and Parcher?

2. What problem does John's medicine cause?

1. They are not real people — John's mind has imagined them for years.

2. The medicine stops the illness, but it also makes John's mind slow, so he cannot think clearly or work.

Talk about it:
  • John must choose: medicine that stops the illness but slows his mind, or no medicine, which is dangerous. Which would you choose?

Part 3 — Learning to live with it

Instead of going back to hospital, John decides — with Alicia's help — to fight the illness with his own mind, not only with medicine. Slowly, he learns to recognise Charles and Parcher when they appear, and he simply chooses to ignore them, even though they still feel real to him.

Years pass. The university lets him sit quietly in the library. Slowly, people trust him again, and he begins to teach once more. Many years after his first big idea, a group of professors tell him quietly that he has won the Nobel Prize. In his speech, he thanks his wife, Alicia, more than anyone — he says love is the answer that matters most.

Quick check — answer from memory, then reveal:

1. How does John learn to manage his illness?

2. Who does John thank most in his speech?

1. He learns to recognise the people his mind imagines, and he chooses not to listen to them or believe them.

2. He thanks his wife Alicia, saying she is the real reason for everything good in his life.

Talk about it:
  • The film says John never fully loses his illness — he only learns to ignore it. Do you think this means he is "better"? What does "better" mean, for an illness like this?

Grammar: who, which and that

This story is full of people and things we need to describe exactly. English uses three small words for this job.

who = for people: "The doctor who helped Nash worked at the hospital."
which = for things: "The idea which made him famous was about competition."
that = for people OR things, very common in speaking: "The prize that he won is very famous."
Feel the difference: use who for a person, which for a thing, and that for either one. No commas are needed — this information tells us exactly which person or thing we mean.

1. who, which or that?

Complete each sentence with the correct word.

1. Alicia is the woman never stopped believing in John.

2. The Nash equilibrium is the idea made him famous.

3. Princeton is the university helped John after his illness.

1. who (a person)

2. which / that (a thing)

3. that / which (a thing)

2. Choose the right word

Complete each sentence with who or which.

1. Charles is the friend was not real.

2. Schizophrenia is the illness John had for many years.

3. The Nobel Prize is the prize John won in 1994.

1. who (a person)

2. which (a thing)

3. which (a thing)

3. Complete the short story

Fill each gap with who, which or that. Read it aloud when you finish.

John is the man had a famous idea about competition. Alicia is the woman stayed with him. The illness he had was very serious, but the prize he won later was very special.

who (a person) · who (a person) · that/which (a thing) · that/which (a thing)

Use who for people, which for things, and that for either.

The Real Story — is any of this true?

Here is the surprising part: the mathematician in this film was a real person, and his real story is even more interesting than the film shows.

🧮 A real prize for a real idea

The real John Nash (1928–2015) was a real mathematician. His idea about competition, called the Nash equilibrium, is used by economists all over the world today. In 1994, he won the Nobel Prize for this idea — one of the biggest prizes in the world.

The illness was real — but not exactly like the film

John really did have a serious mental illness, called schizophrenia. But in real life, he mostly heard voices — he did not see people like Charles and Parcher, the way the film shows. The film made his illness visual, so that we, the audience, could understand it more easily.

Also in real life, John and Alicia divorced in 1963, when his illness was very hard for the family. But Alicia never stopped caring about him, and they married again in 2001. Sadly, in 2015, John and Alicia died together in a car accident, on their way home from receiving another important prize in Norway.

Talk about it:
  • Before this lesson, did you know this story was based on a real person?
  • Does it change the story for you, knowing the real illness was different from the film?
  • Why do you think Alicia stayed connected to John, even after their divorce?

Speak

Do all three tasks out loud. Use the timer to keep talking.

Useful language: use who for people and which or that for things ("the idea that made him famous", "the wife who never left him"). To give an opinion: "I think…", "In my opinion…", "For me…".
Time remaining: 3:00
Task A · Tell the story (3 minutes)

Tell the story of A Beautiful Mind in your own words. Use these steps to help you: a clever, strange student → a big idea in a bar → secret work for the government → the frightening truth about Charles and Parcher → hospital and medicine → learning to live with the illness → the Nobel Prize.

Try to use some key words (genius, university, illness, doctor, imaginary, prize, proud, recover) and who / which / that.

Task B · A hard choice (3 minutes)

John must choose: medicine that stops the illness but makes thinking difficult, or no medicine, which is dangerous. What would you choose? Why?

Task C · Genius and illness (3 minutes)

Talk about being clever, and about illness. Use who, which and that.

Not sure what to say? Choose one:

  • Do you think being very clever can also be difficult? Why?
  • Someone you know or admire who has faced a serious illness.
  • Do you think people understand mental illness better today than in the past?
  • Would you like to be a genius, even if it caused problems in your life?
  • A prize or achievement you would love to win one day.
  • Do you think love can help someone through a difficult illness?

To finish

  1. John says love is the reason for everything in his life. Do you agree that love can help us through hard times?
  2. Alicia never gave up on John. What do you think this shows about her?
  3. From memory: make one sentence with who, one with which, and one with that.
