Ruth Haas

Ruth Haas is a mathematics 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 Ruth Haas rather than just read about it. In short: Ruth Haas is an American mathematician and professor at the University of Hawaii at Manoa. Previously she was the Achilles Professor of Mathematics at Smith College.

Key takeaways

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

Reference excerpt

Ruth Haas is an American mathematician and professor at the University of Hawaii at Manoa. Previously she was the Achilles Professor of Mathematics at Smith College. She received the M. Gweneth Humphreys Award from the Association for Women in Mathematics (AWM) in 2015 for her mentorship of women in mathematics. Haas was named an inaugural AWM Fellow in 2017. In 2017 she was elected President of the AWM and on February 1, 2019 she assumed that position.

Education Haas received her Bachelor of Arts from Swarthmore College, her Master of Science from Cornell University, and her Ph.D. from Cornell University in 1987. Prior to becoming a professor at the University of Hawaii, Haas was Achilles Professor of Mathematics and Statistics at Smith College.

Career Ruth Haas taught at Smith College for many years. She was instrumental in establishing the Center for Women in Mathematics and the post-baccalaureate program at Smith. She has developed and supported several other initiatives, including an undergraduate research course, the annual Women In Mathematics In the Northeast (WIMIN) conference, a program for junior visitors, a high school outreach program, and weekly seminars. The AWM honored Ruth Haas’s outstanding achievements in inspiring undergraduate women to discover and pursue their passion for mathematics and eventually becoming mathematicians by awarding her the 2015 M. Gweneth Humphreys Award.

Worked examples

Example 1 — a first encounter with Ruth Haas

Start with the simplest possible case. Write down what Ruth Haas claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, 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 Ruth Haas 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 Ruth Haas 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 Ruth Haas

In research: Ruth Haas appears in mathematics 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 Ruth Haas 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: Ruth Haas is common in secondary-school and first-year university syllabi. It links to neighbouring topics 20th-century American mathematicians, 20th-century American women mathematicians, 21st-century American mathematicians, so understanding it makes those chapters shorter.
In everyday life: Look for Ruth Haas 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.
