ProCare

ProCare is a science 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 ProCare rather than just read about it. In short: ProCare was a service offered by Apple Computer for use at Apple retail stores providing enhanced access to services from the Genius Bar. ProCare had an annual membership fee of US$99 for use with up to three Apple computers.

Key takeaways

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

Reference excerpt

ProCare was a service offered by Apple Computer for use at Apple retail stores providing enhanced access to services from the Genius Bar. ProCare had an annual membership fee of US$99 for use with up to three Apple computers. Among the services included with membership were scheduling of Genius Bar reservations up to 14 days in advance (vs. 3 days for non-members) and faster turnaround times for in-store repairs. ProCare membership also included personalized setup of new machines, a yearly 'tune-up' and 'backup consultation'. ProCare previously included individualized training and instruction on a variety of topics relating to Apple computers and software, but as of May 2, 2007, this was spun off as a separate training service called One to One. On March 3, 2011, the ProCare service was superseded by Joint Venture from Apple.

Worked examples

Example 1 — a first encounter with ProCare

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

In research: ProCare appears in science 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 ProCare 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: ProCare is common in secondary-school and first-year university syllabi. It links to neighbouring topics Apple Inc. services, Consumer electronics brands, Products and services discontinued in 2007, so understanding it makes those chapters shorter.
In everyday life: Look for ProCare 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.

Frequently asked questions

What is ProCare in simple terms?

Why does ProCare matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study ProCare?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
