Mary James (scientist)

Mary James (scientist) is a physics 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 Mary James (scientist) rather than just read about it. In short: Mary B. James is an American physicist and educator.

Key takeaways

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

Reference excerpt

Mary B. James is an American physicist and educator. She is the Dean for Institutional Diversity and the A. A. Knowlton Professor of Physics at Reed College. James specializes in particle physics and accelerators.

Early life and education James' father was one of the Tuskegee Airmen. She earned a bachelor's in physics at Hampshire College in 1976. She completed a PhD in accelerator physics at Stanford University in 1986. She worked at SLAC National Accelerator Laboratory, designing high current electron injectors for the linear collider. She studied the longitudinal bunching of transrelativistic electron beams in high space charge forces and longitudinal wake fields. At SLAC National Accelerator Laboratory she also contributed to the polarized electron injector (PEGGY).

Research and career In 1977 James worked with Dr. R. H. Miller to design a new focusing system for SLAC's position source. In 1987 James joined University of Maryland, College Park as an assistant professor in electrical engineering. Soon thereafter she moved to Portland, Oregon, to join the faculty of the department of physics at Reed College, where she has been a faculty member since in 1988. At Reed, James has taught broadly across the physics curriculum. In 1991 she was in Stanford, California working for Stanford Linear Accelerator Center (SLAC), on a Special Projects Group. James has been an advocate for women and minority students throughout her career. In 2013 James was announced as Dean for Institutional Diversity at Reed College. She is on the leadership team of the Liberal Arts Diversity Officers consortium. The consortium looks at how faculty can navigate incidents of bias, and develops ways to change the structure and allow them to thrive. James contains a hard core belief that the physics department should adopt a more welcoming environment for people of color, specifically African Americans in order grow the diversity in the physics community. She has served as a member and chair for the American Physical Society committee on Minorities in Physics. She established Reed College's Center for Teaching and Learning, which looks to attract and retain women, first generation students and people of color in STEM majors. She is concerned that underrepresented minority students feel isolated on campus, and that faculty of colour invest time in mentoring for minority students which distract from the tenure process. When classes at Reed College were cancelled due to student protests over a curriculum that was "too white, male and Eurocentric", Reed appeared on public radio and national media emphasizing the need for inclusive pedagogy. As a teacher, she creates an active learning environment which makes students recognize physics does not only need straight A students. Working with the American Institute of Physics she launched TEAM UP in April 2018, a Task Force to Elevate African American Representation in Undergraduate Physics & Astronomy. The program involved a survey, site visits and evidence-based recommendations with pilot schools. The report from the Task Force appeared in spring 2020 and identifies a number of the factors responsible for the success of African American students in physics and astronomy along with research-based recommendations for faculty and institutions to increase the representation of African Americans in these fields. The key barriers cited in the report included financial burdens, departmental culture and 'physics identity' and belonging. Comments and updates on the results of this task force have recently been published.

Recognition James was named a Fellow of the American Physical Society (APS) in 2021, after a nomination from the APS Forum on Physics and Society, "for outstanding contributions to improving access, inclusion, equity, and mentorship in physics, including as co-chair of the TEAM-UP Task Force, speaking at CUWiP conferences, and as Dean for Institutional Diversity at Reed College".

Worked examples

Example 1 — a first encounter with Mary James (scientist)

Start with the simplest possible case. Write down what Mary James (scientist) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 Mary James (scientist) 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 Mary James (scientist) 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 Mary James (scientist)

In research
Mary James (scientist) appears in physics 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 Mary James (scientist) 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
Mary James (scientist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 20th-century African-American scientists, 20th-century African-American women, 20th-century American physicists, so understanding it makes those chapters shorter.
In everyday life
Look for Mary James (scientist) 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.
