Nash's behavior was often erratic from "summary" of A Beautiful Mind by Sylvia Nasar
Throughout the narrative, Nash's behavior is portrayed as unpredictable and inconsistent. At times, he appears to be a brilliant and dedicated mathematician, fully engrossed in his work with a sharp focus and determination. However, this is juxtaposed with moments of extreme paranoia and delusion, where he is plagued by irrational fears and erratic behaviors that disrupt his personal and professional life. For example, Nash becomes convinced that he is being followed by mysterious government agents and starts to act in ways that are incomprehensible to those around him. He becomes increasingly isolated and withdrawn, refusing to engage with colleagues and friends, and exhibiting signs of extreme distress and agitation. This behavior is a stark contrast to his usual composed and rational demeanor, leaving many perplexed and concerned about his mental well-being. Despite these episodes of irrationality, Nash's brilliance shines through in his groundbreaking work in mathematics. His ability to think outside the box and tackle complex problems with innovative solutions is evident in his contributions to the field. However, his erratic behavior poses a significant challenge to his career and personal relationships, as he struggles to maintain a sense of stability and control in his life.- Nash's behavior is a complex interplay of genius and madness, where his exceptional intellect is often overshadowed by his erratic and unpredictable actions. This dichotomy adds depth and intrigue to his character, painting a vivid portrait of a man grappling with inner demons while striving for greatness in his professional pursuits.
