Ruth Begun

Ruth Begun is a engineering 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 Begun rather than just read about it. In short: Ruth Begun (née Weltmann) (3 April 1912 in Berlin, Germany - 11 November 2014 in Ohio, US). was the first woman to be awarded a physics PhD from the University of Berlin for her thesis on boundary layers of non-compressible fluids. She worked as rheologist and an Aerospace Engineer.

Key takeaways

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

Reference excerpt

Ruth Begun (née Weltmann) (3 April 1912 in Berlin, Germany - 11 November 2014 in Ohio, US). was the first woman to be awarded a physics PhD from the University of Berlin for her thesis on boundary layers of non-compressible fluids. She worked as rheologist and an Aerospace Engineer.

Scientific work She migrated to the United States in 1937 with her soon-to-be husband Semi Joseph Begun whom she married a year later. In the same year of her migrating, she started working at Interchemical corporation in New York City. In 1941 (or 1948) she moved to Ohio where she joined the NASA Glenn Research center as an Aerospace Engineer and co-developed the spacecraft ion engine before she was discharged of her duties in 1973. In 1976 she filed a lawsuit against NASA claiming she was unlawfully discharging her from her job claiming systemic sex discrimination. Although women published before her, due to her well documented publications she is considered the 'first woman industrial rheologist'. During her work at Interchemical Corporation she met Henry Green, whom she worked with closely. In 1944, when Green developed an improved Couette-type rotational viscometer she developed and patented an accompanying recorder in 1945. The flow curves recording mechanism allowed immediate interpretation and calculation of several values plastic viscosity, the yield value, and study the thixotropic behaviour. In her published work she proposed new analysis methods of rotational measurements and studied the properties of colloidal suspensions.

Charitable work In 1972, the Beguns founded the Society for the Prevention of Violence (SVP) followed by 2001 the 'Begun Foundation' a supporting Foundation of the Jewish Federation of Cleveland, the foundation was dedicated to addressing the increased violence in society. The Mandel School in Case Western University celebrated The Beguns social work in 2000 by establishing an endowed chair position to support a faculty member working in anti-violence research and education.

Other Begun wrote her first of book series 'Social Skills: Lessons and Activities for Pre-K' in 1990. Later she co-authored 'Ready-to-Use Violence Prevention Skills Lessons and Activities for Secondary Students' 1998 and 'Ready-to-Use Violence Prevention Skills Lessons and Activities for Elementary Students' in 1999 with Frank J. Huml.

Worked examples

Example 1 — a first encounter with Ruth Begun

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

In research: Ruth Begun appears in engineering 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 Begun 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 Begun is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1912 births, 2014 deaths, 20th-century American engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Ruth Begun 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.
