1. IDEA 1 OF 8

   A brilliant mathematician

   Nasar tells the story of John Nash, a gifted mathematician who made major discoveries as a young man at Princeton.

   His work on game theory later changed economics. Nasar shows that his talent was clear to those around him from very early on.

2. IDEA 2 OF 8

   He discovered an equilibrium

   Nash developed the idea now called the Nash equilibrium, a situation where no player can benefit by changing strategy alone.

   It became central to game theory. Nasar presents this as a clear way of thinking about how people make choices when others' choices matter.

3. IDEA 3 OF 8

   Game theory changed economics

   Nasar explains how Nash's work helped economists understand competition and cooperation.

   It influenced many fields. Nasar shows that his ideas about strategy proved useful far beyond mathematics, for example in markets and bargaining.

4. IDEA 4 OF 8

   Illness struck

   In his early thirties, Nash developed schizophrenia, a serious mental illness.

   He experienced delusions and could no longer work. Nasar presents the illness as a cruel turn that took away a brilliant mind just as it was at its peak.

5. IDEA 5 OF 8

   Alicia stood by him

   Nasar describes Nash's wife, Alicia, who supported him through years of illness.

   Their relationship was difficult but lasting. Nasar shows that her patience through hard years was an important part of his story.

6. IDEA 6 OF 8

   Years were lost

   Nash spent decades struggling with illness, often wandering Princeton's campus.

   Many people forgot his achievements. Nasar shows that illness can hide a person's gifts for many years, while the person still deserves care.

7. IDEA 7 OF 8

   Recovery came slowly

   Over time, Nash's symptoms lessened, and he returned to mathematics.

   His recovery surprised many. Nasar shows that he slowly came back to the work he loved, and that people around him welcomed this change.

8. IDEA 8 OF 8

   Recognition arrived

   In 1994, Nash shared the Nobel Prize in Economics for his early work.

   His story inspired many. Nasar presents the prize as late recognition for work he had done when he was young.
