NearGlobal

NearGlobal 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 NearGlobal rather than just read about it. In short: NearGlobal is a London, based software developer and publisher of Near, a 3D city browser platform and virtual world technology that delivers survey-accurate models of real-world cities that users can explore and interact with from their computer. The Near software was released in December 2009 with a public beta version incorporating the key shopping districts of London's West End.

Key takeaways

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

Reference excerpt

NearGlobal is a London, based software developer and publisher of Near, a 3D city browser platform and virtual world technology that delivers survey-accurate models of real-world cities that users can explore and interact with from their computer. The Near software was released in December 2009 with a public beta version incorporating the key shopping districts of London's West End.

Purpose NearGlobal describes the Near product as a discovery platform, rather that a virtual world. Near allows for the seamless integration of existing web-based content into the 3D environment.

Differentiation Near differs significantly from virtual worlds such as Second Life, Twinity and Blue Mars by focusing more on the presentation of the environment than on its users. The Near software depicts users with blades of light rather than with human avatars.

Worked examples

Example 1 — a first encounter with NearGlobal

Start with the simplest possible case. Write down what NearGlobal 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 NearGlobal 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 NearGlobal 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 NearGlobal

In research: NearGlobal 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 NearGlobal 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: NearGlobal is common in secondary-school and first-year university syllabi. It links to neighbouring topics Hypermedia, Virtual reality companies, Virtual world communities, so understanding it makes those chapters shorter.
In everyday life: Look for NearGlobal 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 NearGlobal in simple terms?

Why does NearGlobal 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 NearGlobal?

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.
