GoldStar

GoldStar is a astronomy 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 GoldStar rather than just read about it. In short: GoldStar was a South Korean electronics company established in 1958. The corporate name was changed to LG Electronics and LG Cable on February 28, 1995, after merging with Lucky Chemical.

Key takeaways

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

Reference excerpt

GoldStar was a South Korean electronics company established in 1958. The corporate name was changed to LG Electronics and LG Cable on February 28, 1995, after merging with Lucky Chemical. LG Cable was spun off from LG Electronics and changed its name to LS Cable in 2005.

Manufacturing GoldStar manufactured a wide variety of products, including radios, televisions, air conditioners, MSX home computers, LCD games, videocassette recorders, video and audio cassette tapes, microwave ovens, electronic typewriters, integrated circuits, escalators, elevators, injection molding machines, dehumidifiers, fans, and tractors. GoldStar televisions became a commonly sold brand of consumer television sets in the United States in the 1980s. GoldStar Precision was a division manufacturing electronic test equipment such as multi-meters and oscilloscopes and industrial electronics. The name was changed to LG Precision with the merger, with many of the same products and model numbers being produced but with new branding. The measuring device division was acquired by EZ Digital in 1999, again with identical or similar model numbers. The industrial products continue under the company name LIG Nex1.

Motors GoldStar tractors began in 1975, as a division of Hyundai, in cooperation with Yanmar of Japan. In 1977, they began cooperation with Fiat of Italy, and in 1983, was acquired by GoldStar. Both companies, Lucky Chemicals and Goldstar Co. Ltd, merged and formed Lucky-Goldstar in this year. That same year, they began cooperation with Mitsubishi, and re-established cooperation with Fiat in 1984. Tractors were sold under the GoldStar and Fiat-GoldStar brands. Fiat-GoldStar was a brand of tractors sold in cooperation with the Fiat company of Italy. The Fiat-GoldStar name was discontinued when GoldStar changed its corporate name to LG Cable.

Other products GoldStar also produced some models of computer monitors, optical disc drives and a model/version of multimedia videogame console 3DO, along with several manufacturers such as Sanyo, JVC or Samsung among others.

Worked examples

Example 1 — a first encounter with GoldStar

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

In research: GoldStar appears in astronomy 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 GoldStar 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: GoldStar is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2002 disestablishments in South Korea, Computer companies of South Korea, Defunct computer hardware companies, so understanding it makes those chapters shorter.
In everyday life: Look for GoldStar 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 GoldStar in simple terms?

GoldStar was a South Korean electronics company established in 1958. The corporate name was changed to LG Electronics and LG Cable on February 28, 1995, after merging with Lucky Chemical.

Why does GoldStar matter?

Because it connects several astronomy 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 GoldStar?

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.
