Weike Wang’s ‘Chemistry’ charts a young woman’s toxic reaction to stress – Washington Post

By Jamie Fisher By Jamie Fisher June 9

Weike Wangs Chemistry is the most assured novel about indecisiveness youll ever read. Consider its opening lines: The boy asks the girl a question. It is a question of marriage. Ask me again tomorrow, she says, and he says, Thats not how this works.

The boy is Eric; the girl, our narrator, goes unnamed. Both are graduate students in chemistry: He has just graduated; she has one year left. They have been together for four years, and their relationship has reached the point where whenever she invites friends over for dinner, they assume she will announce her engagement. But when Eric really does propose, she hovers, uncertain and unnerved.

Eric is cheerful, capable, from small-town Maryland. (The narrator wonders why he left a place where every ice-cream shop is called a creamery to work seventy-hour weeks in lab.) Their relationship is bashful and enormously endearing. He compliments her vials. When he gets the job offer hes been hoping for, he puts a doily on her head and dances her around the kitchen. So why wont she say yes?

The title Chemistry also, of course, alludes to love. But in Chinese the word for chemistry translates to the study of change. The novel is equally about the narrators slow self-transformation and her relationship with Eric. Both have arrived at a catalytic moment: the indecision each reaction faces before committing to its path.

[Yiyun Lis brave look at depression and the consoling power of literature]

Her best friend is a successful doctor, her lab mate miraculously efficient, and the narrator finds it difficult not to compare their careers with her own, which seems to have stalled. In high school she was an award-winning student. As an undergrad she became fascinated with synthetic organic chemistry, not quite anticipating that as a graduate student her job would require, say, repeating step No. 8 of a 24 step synthesis for months, just so I can get the yield up from 50 percent to 65.

Chemistry is narrated in a continual present tense, which, in conjunction with Wangs marvelous sense of timing and short, spare sections, can make the novel feel like a stand-up routine. (Compare the boy asks the girl a question to a classic setup like a horse walks into a bar.) Personal crises are interrupted, to great effect, with deadpan observations about crystal structures and the beaching patterns of whales. The spacing arrives like beats for applause.

But the present tense also suggests the extent to which the past is, for this narrator, an ongoing anxiety. Its hard for her not to contrast her immigrant parents phenomenal will unfavorably against her own. After all, her father made it from the backwaters of rural China to graduate school and America. The narrator explains, Such progress hes made in one generation that to progress beyond him, I feel as if I must leave America and colonize the moon.

Her parents expect nothing less. Growing up, her father instructs, Tell me the time in arc second per second or dont tell me at all. When she confesses to her mother that shes leaving graduate school, her mother screams, You are nothing to me without that degree.

Think small, the narrator counsels herself, think doable, think of something that might impress no one but will still let you graduate and find a job. But she cant think, she doesnt know what she wants, and if she cant decide, she may lose everything: Eric, her career, her self-worth.

Despite its humor, Chemistry is an emotionally devastating novel about being young today and working to the point of incapacity without knowing what you should really be doing and when you can stop. I finished the book and, after wiping myself off the floor, turned back to an early passage when the narrator asks her dog, What do you want from me? You must want something.

It doesnt.
