Key takeaways

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

Reference excerpt

Kathleen Rachel Makinson (née White) (15 February 1917 – 18 October 2014) was an Australian physicist and the first woman to become a chief research scientist at the country's research organization, CSIRO.

Biography Kathleen Rachel White was born 15 February 1917 near London, England the eldest of three children. She was remembered by one teacher as "a voracious reader at school". She became interested in science at age 12 or 13, "I got hooked on atoms and molecules". Growing up in England, during the Depression, her father lost his job as a head teacher and found employment, but with a reduction in pay. She learned as a teenager that teachers' salaries varied by gender, saying "the Council that ran the schools 'appointed female heads at half the salary'." She earned a Bachelor of Arts (1939) and, later, a PhD in physics (1970), both from Newnham College, part of the University of Cambridge, in England. She had been awarded a scholarship to study physics at Cambridge University, achieving a Double First in 1939, and was aiming for a career in X-ray crystallography, but after meeting an Australian physicist at the university, she agreed to postpone her doctorate, move to his home country and marry. She arrived with her husband, Richard Makinson (1913–1979), as World War II was raging in Europe. In Australia, her husband was offered a position at the University of Sydney as a physics lecturer but no similar position was offered to Rachel as the country had placed rigid barriers to prevent most employment of married women.

Researcher In the 1940s, Rachel Makinson, her preferred name, took the opportunities she had, including tutoring "several cohorts of RAAF airmen in the rudiments of radio physics as a precursor to radar training". She was enlisted to join a team of 60 physicists to develop radar technology at Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO), in the Radiophysics Laboratory and was one of only three women on the team, including Ruby Payne-Scott, and Joan Maie Freeman.

Expertise After the end of World War II, research into the physics of wool fibres had become increasingly important to Australian wool producers, which inspired the CSIRO to launch a Division of Textile Physics. The organizers recruited as a scientific officer "a young Englishwoman," Makinson, who would become "an international authority on felting, friction and shrinkproofing" of woolen textiles. She is quoted as saying that, at the time, "next to nothing" was known about of the physical properties of wool fibres or about the processes of felting and shrinkage. The only shrinkproofing method available at that time was chlorination, however that process was known to damage the wool fibres and was not well understood from a scientific perspective. Makinson began work in the Division of Textile Physics in 1953, and was a senior principal research scientist from 1971 to 1977. She devoted her research to carefully examining the "underlying physics of wool fibres and their microscopic interactions." Her appointment did not come without obstacles. As a married woman, she was denied the chance to hold a permanent position at the CSIRO so, for many years, she was retained as a temporary employee and had to seek official reappointment every year. Beginning in the early 1960s, Makinson used her own organizational success to campaign for the fair treatment of her female colleagues. To do so, she helped form the CSIRO Officers Association and used that group to promote equal pay for women on the staff. By applying her research skills, she collected and presented data to management supporting her causes illustrating "the systemic nature of discrimination in pay and seniority".

She was the first woman to become a chief research scientist at CSIRO (1977–1982). From 1979 to 1982, she was the assistant chief of the division, also the first woman to hold such a position. According to her obituary, she succeed despite obstacles,"In 1979, she became Assistant Chief of Division, the first woman to achieve that rank in CSIRO (having been told by her male boss some years before that 'I will not have a woman in a senior position if I can help it.')".

Final years Throughout her life she loved bushwalking, identifying native plants and exploring Aboriginal Australia. After the death of her husband in 1976 and her retirement from CSIRO, Makinson moved to the Blue Mountains, where she became active in conservation efforts with the Blue Mountains Conservation Society and Historical Society. When her health declined in the 1990s, she returned to Sydney and died 18 October 2014, survived by two sons.

Honors 1981: Elected a Fellow of the Australian Academy of Technological Sciences and Engineering 1982: Made a Member of the Order of Australia (AM) "for public service in the field of wool research" 1987: Made a Fellow of the Australian Academy of Technological Sciences and Engineering (FTSE) (1987-2014) 2003: Awarded the Commonwealth Government's centenary medal "for service to Australian Society in textile physics"

Worked examples

Example 1 — a first encounter with Rachel Makinson

Start with the simplest possible case. Write down what Rachel Makinson 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 Rachel Makinson 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 Rachel Makinson 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 Rachel Makinson

In research
Rachel Makinson 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 Rachel Makinson 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
Rachel Makinson is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1917 births, 2014 deaths, 20th-century Australian women scientists, so understanding it makes those chapters shorter.
In everyday life
Look for Rachel Makinson 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.
