Stanley Shanfield

Stanley Shanfield 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 Stanley Shanfield rather than just read about it. In short: Stanley Shanfield serves as a Distinguished Member of the Technical Staff and Technical Director of Advanced Hardware Development at the Charles Stark Draper Laboratory in Cambridge, Massachusetts, a post he has held since 2003. He is the holder of seven patents and has led teams responsible for inventing and manufacturing new technologies in the fields of semiconductor device fabrication and optical electronics.

Key takeaways

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

Reference excerpt

Stanley Shanfield serves as a Distinguished Member of the Technical Staff and Technical Director of Advanced Hardware Development at the Charles Stark Draper Laboratory in Cambridge, Massachusetts, a post he has held since 2003. He is the holder of seven patents and has led teams responsible for inventing and manufacturing new technologies in the fields of semiconductor device fabrication and optical electronics.

Professional Biography Following his graduation from the University of California, Irvine, where he received a B.S. in Physics in 1977, Stanley Shanfield went on to complete a Doctoral degree from the Massachusetts Institute of Technology (PhD, 1981). As a newly graduated physicist he became a staff scientist and later senior scientist with Spire Corporation of Bedford, Massachusetts, a manufacturer of renewable energy photovoltaics (1981–1984). In 1985 he joined Raytheon Corporation, serving for seven years as Section Manager for Semiconductors. His work there focused primarily on designs for integrated circuits. In 1992 he was promoted to Laboratory Manager, overseeing the invention of a pseudomorphic high electron mobility transistor. In 1996 he became Manager, Semiconductor Operations, a post he held for three years before a two-year stint as Vice President of Operations at AXSUN Technologies of Bedford, Massachusetts. There he oversaw the development and production of the company's micro-electromechanical (MEM) Fabry-Perot optical filter. As a result of this work Dr. Shanfield was awarded patents for semiconductor processing and control electronics. In 2001 he joined Clarendon Photonics (Newton, Massachusetts) as Director, Packaging & Integration, a post he held until 2003. There he invented a new semiconductor technology for optical add-drop multiplexers. His research at Draper Labs, where he began work in 2003, has resulted in the invention of an ultra-miniature electronics fabrication technology, a newly designed precision MEMS-based gyroscope and associated ASIC (application-specific integrated circuit), the development of a miniaturized power source, and the technology and manufacturing process for a semiconductor-based low phase noise oscillator. He currently consults throughout the world as an expert in these matters through Rubin/Anders Scientific, Inc.

Awards and honors Dr. Shanfield's undergraduate and graduate school careers were marked by several distinctions. Besides attending college on full scholarship, graduating Cum Laude and being elected to Phi Beta Kappa, he won the prestigious U.C. Regents Award for outstanding research project (1975).

Worked examples

Example 1 — a first encounter with Stanley Shanfield

Start with the simplest possible case. Write down what Stanley Shanfield 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 Stanley Shanfield 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 Stanley Shanfield 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 Stanley Shanfield

In research
Stanley Shanfield 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 Stanley Shanfield 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
Stanley Shanfield is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century physicists, Living people, University of California, Irvine alumni, so understanding it makes those chapters shorter.
In everyday life
Look for Stanley Shanfield 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.
