Martin Wachs

Martin Wachs 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 Martin Wachs rather than just read about it. In short: Martin Wachs (1941–2021) was an American professor emeritus of Urban Planning at the University of California, Los Angeles and of City and Regional Planning and of Civil and Environmental Engineering at the University of California, Berkeley. He began his career in university teaching in 1968 and retired from teaching in 2006, to work at the Rand Corporation until 2010.

Key takeaways

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

Reference excerpt

Martin Wachs (1941–2021) was an American professor emeritus of Urban Planning at the University of California, Los Angeles and of City and Regional Planning and of Civil and Environmental Engineering at the University of California, Berkeley. He began his career in university teaching in 1968 and retired from teaching in 2006, to work at the Rand Corporation until 2010.

Early years Martin Wachs was born June 8, 1941. He attended City College, City University of New York, receiving his bachelor's degree in 1963. He received his master's degree (1965) and his PhD in civil engineering from Northwestern University in 1967.

Career He taught at University of Illinois at Chicago as assistant professor of systems engineering, then as assistant professor of civil engineering at Northwestern University before heading west to California. He was an associate professor in a newly founded Graduate School of Architecture and Urban Planning at University of California, Los Angeles in 1971, the start of a long career in the University of California system. Besides teaching in Los Angeles, he spent 10 years at UC Berkeley, with the Institute of Transportation Studies. He was one of the earliest scholars to address transportation's relationship to social equity, environmental quality, and community values. He wrote 180 articles and four books on subjects related to transportation and land use. Wachs was awarded the Guggenheim Fellowship for his exceptional scholarship in Architecture, Planning and Design and the Carey Award for service to the Transportation Research Board. He retired from teaching in 2006, to work at the Rand Corporation until 2010. In recognition of his extraordinary service, Wachs was honored by the American Institute of Certified Planners and the National Academy of Sciences.

Death Martin Wachs died at his home in Los Angeles on April 12, 2021, in the midst of collaborating on papers with colleagues.

Worked examples

Example 1 — a first encounter with Martin Wachs

Start with the simplest possible case. Write down what Martin Wachs 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 Martin Wachs 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 Martin Wachs 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 Martin Wachs

In research: Martin Wachs 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 Martin Wachs 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: Martin Wachs is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1941 births, 2021 deaths, Public transport activists, so understanding it makes those chapters shorter.
In everyday life: Look for Martin Wachs 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.
