Mian Chin

Mian Chin is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Mian Chin rather than just read about it. In short: Mian Chin (Chinese: 秦勉; pinyin: Qín Miǎn) is a Chinese atmospheric chemist. She is a physical scientist in the atmospheric chemistry and dynamics laboratory in the earth science division at Goddard Space Flight Center.

Key takeaways

  • Mian Chin belongs to chemistry; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Mian Chin to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Mian Chin from memory before moving on to harder problems.

Reference excerpt

Mian Chin (Chinese: 秦勉; pinyin: Qín Miǎn) is a Chinese atmospheric chemist. She is a physical scientist in the atmospheric chemistry and dynamics laboratory in the earth science division at Goddard Space Flight Center. Her research includes aerosol-cloud-chemistry-climate interactions. She received the NASA Exceptional Achievement Medal in 2005.

Early life and education Chin was born in Shanghai, China. Beginning at the age of nine, Chin attended the Children's Music School at the Shanghai Conservatory of Music for three years to study piano. When she was thirteen, her education abruptly stopped due to the Cultural Revolution. After a little more than two years idling at school with chaos everywhere in China, Chin was sent to a farm in the very north of China near Siberia, three days away from Shanghai by train, as part of Mao Zedong's educated youth program. Many other children her age were sent there as well. More than forty children lived in one room. They each had a “living” space of two feet. She worked on that farm for nine years, until Chairman Mao's death, which ended the Cultural Revolution. For nine years, a Chin and group of other children quietly studied math, physics and chemistry. Her parents and friend's mother in Shanghai sent them textbooks and they taught themselves. At the farm, they had no phones. Electricity had to be turned off no later than 9 p.m., so they studied in the evenings with candlelight. In 1977, the National College Entrance Examination that were stopped during the Cultural Revolution, resumed. Chin had to take two college entrance exams, a preliminary and a final. Because of her studies at night, she passed the preliminary exam. After the preliminary test results came back, Chin was given two hours to choose a college and a major from the hand-written list posted on the walls inside a classroom in a local elementary school. She chose one college that was near her home in Shanghai as well as others in different places. Chin received a B.S. degree in chemistry from East China Normal University in 1982, a M.A. degree in chemistry from Ball State University in 1986, and a Ph.D. degree in Atmospheric Sciences from Georgia Tech in 1992. During her graduate study in Georgia Tech, Chin was involved in field experiments measuring atmospheric constituents, laboratory study determining atmospheric photochemical reaction rates and product yields, and one-dimensional photochemical model estimating stratospheric sulfur budget. Her dissertation was titled An atmospheric study of carbonyl sulfide and carbon disulfide and their relationship to stratospheric background sulfur aerosol. Chin's doctoral advisors were Paul Wine and Douglas Davis. Between 1992 and 1995, Chin was a postdoctoral fellow in the Harvard John A. Paulson School of Engineering and Applied Sciences where she worked with 3-dimensional regional and global atmospheric chemistry and transport models for studying tropospheric ozone, aerosols, and trace gases.

Career Chin was a research scientist at Universities Space Research Association from 1995 to 1997 and a research scientist and senior research scientist at Georgia Institute of Technology from 1997 to 2003 before she joined the NASA Goddard Space Flight Center in 2003, concentrating on atmospheric model development and satellite data analysis. Chin is a physical scientist in the Atmospheric Chemistry and Dynamics Laboratory, Earth Science Division, at the NASA Goddard Space Flight Center (GSFC).

Research Chin has served as principal investigator for many research projects since 1997 that involve global and regional modeling of tropospheric aerosols and chemistry. She and her coworkers have developed the Goddard Chemistry Aerosol Radiation and Transport (GOCART) model, which has been used to simulate tropospheric aerosols and related gas species, CO, and radionuclides for climate, air quality, and global change studies, with a special focus on analysis of satellite and sub-orbital observations. Chin's research at GSFC includes aerosol-cloud-chemistry-climate interactions, regional and global air quality, transport of aerosols and trace gases, aerosol impacts on global energy balance, and modeling and analysis of data from satellite, ground-based, and airborne observations.

Awards and honors In 1997, Chin received the Editor's Citation for excellence in refereeing from the Journal of Geophysical Research. In 2005, she was awarded the exceptional achievement award and NASA Exceptional Achievement Medal from GSFC. In 2021, Chin was elected a fellow of the American Geophysical Union.

Worked examples

Example 1 — a first encounter with Mian Chin

Start with the simplest possible case. Write down what Mian Chin claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Mian Chin before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Mian Chin ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Mian Chin

In research
Mian Chin appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Mian Chin in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Mian Chin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 20th-century Chinese chemists, 20th-century Chinese scientists, 20th-century Chinese women scientists, so understanding it makes those chapters shorter.
In everyday life
Look for Mian Chin outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
