Key takeaways

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

Reference excerpt

Paul Charles Michaelis was a Bell Labs researcher in magnetic bubble memory.

Education Michaelis was born June 18, 1935, in New York City, raised in New Jersey on a Scotch Plains farm, went to high School in Scotch Plain, First worked in Bell Labs, Murray Hill, New Jersey, starting career as a junior draftsman, attended its drafting school. Subsequently, attended NCE Newark College of Engineering, (now "New Jersey Institute of Technology") Received BSEE, BSME and MS physics. After several promotions was promoted to member of Bell Laboratories technical staff and subsequently promoted to technical manager, New Jersey.

Career Michaelis spent 43 years with Bell Labs, primarily in Murray Hill and Whippany. He primarily dealt with mechanics, magnetics, fiber optics, electrical circuits, device packaging, acoustic surveillance and vibration reduction. He also worked on underwater surveillance devices and equipment silencing for the United States Navy. Michaelis was a guest lecturer in magnetics at the Soviet Academy of Sciences USSR in 1972, lecturing at the University of Moscow, University in Tbilisi, Soviet Georgia and the Semiconductor Institute in Leningrad [now St Petersburg]. Michaelis retired from Bell Labs in 1996 as technical manager of the Advanced Vibration Reduction Design Group.

Notable awards Michaelis received the 1975 IEEE Morris N. Liebmann Memorial Award "for the concept and development of single-walled magnetic domains (magnetic bubbles), and for recognition of their importance to memory technology." The single walled concept was the seminal idea that led to "magnetic bubbles" and charge coupled devices.

Worked examples

Example 1 — a first encounter with Paul Charles Michaelis

Start with the simplest possible case. Write down what Paul Charles Michaelis 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 Paul Charles Michaelis 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 Paul Charles Michaelis 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 Paul Charles Michaelis

In research: Paul Charles Michaelis 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 Paul Charles Michaelis 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: Paul Charles Michaelis is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1935 births, American electrical engineers, Engineers from New Jersey, so understanding it makes those chapters shorter.
In everyday life: Look for Paul Charles Michaelis 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.
