Nokia Lumia 820 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Nokia Lumia 820 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Nokia Lumia 820 from memory before moving on to harder problems.

Reference excerpt

The Nokia Lumia 820 is a smartphone designed, developed and marketed by Nokia. It is the successor to the Lumia 800 and is one of the first Nokia phones to implement Windows Phone 8 alongside the Nokia Lumia 920. Although sharing a similar appearance with the Lumia 800, the Lumia 820 is a major overhaul over its predecessor, sporting a 4.3 inches (110 mm) diagonal OLED display with scratch resistant glass, though lacking Gorilla Glass protection, 1.5 GHz dual-core processor, and an 8.7-megapixel camera. The phone will come with LTE connectivity and a wireless-charging option. The 820 is the first Nokia Windows Phone OS based smartphone to embed a microSD card slot. A range of interchangeable back shells were released for it, which allow the back shell of the phone to be easily swapped and customized, along with providing features such as wireless charging if a compatible shell is used. On October 9, 2012, the largely similar Nokia Lumia 810 was presented. The main differences are more talk time (10.2 hours) due to the larger 1800 mAh battery, an improved 1.3-megapixel front-facing camera, lighter weight, wider and longer dimensions. The Lumia 810 is exclusively made available to T-Mobile customers in the United States, and as such does not support LTE but only HSPA+, as LTE was not supported in T-Mobile's US network at the time of release. On October 29, 2012, another variant of the Lumia 820, the Nokia Lumia 822 was announced, having a better front camera, larger battery and double the storage. It is exclusively available for Verizon customers.

Reception Jeff Parsons from Techradar wrote: "The Nokia Lumia 820 sits nicely at the crossroads between value and power. While it doesn't have the processor, camera or larger screen of its big brother the Lumia 920, it does have microSD storage, removable covers and a more attractive price tag." Mike Jennings from PC Pro wrote: "The low-resolution screen, weaker camera and continued lack of apps mean it can’t compete with the best Android handsets, but the usability of Windows 8 and attractive physical design mean this well-balanced Nokia is still an attractive proposition." Stuart Miles from Pocket-Lint.com wrote: "This is the phone Nokia should be putting all its efforts into promoting. Agreed it isn’t the flagship and agreed the camera isn't nearly anywhere as good as on the 920, but this is a phone you'll be happy to use, a phone you'll enjoy using, and besides a lack of third-party apps at the moment, a phone that for many people will be a fantastic phone they will enjoy for the next two years."

Worked examples

Example 1 — a first encounter with Nokia Lumia 820

Start with the simplest possible case. Write down what Nokia Lumia 820 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 Nokia Lumia 820 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 Nokia Lumia 820 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 Nokia Lumia 820

In research: Nokia Lumia 820 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 Nokia Lumia 820 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: Nokia Lumia 820 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Discontinued smartphones, Microsoft Lumia, Mobile phones introduced in 2012, so understanding it makes those chapters shorter.
In everyday life: Look for Nokia Lumia 820 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.
