Kosik (elephant)

Kosik (elephant) 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 Kosik (elephant) rather than just read about it. In short: Kosik (Korean: 코식; born 1990) is a male Indian elephant (Elephas maximus) in the Everland theme park in Yongin, South Korea. He made headlines in September 2006 when it was discovered he could imitate the Korean words for "yes" (네), "no" (아니요), "sit" (앉아), "lie down" (누워), and four other words.

Key takeaways

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

Reference excerpt

Kosik (Korean: 코식; born 1990) is a male Indian elephant (Elephas maximus) in the Everland theme park in Yongin, South Korea. He made headlines in September 2006 when it was discovered he could imitate the Korean words for "yes" (네), "no" (아니요), "sit" (앉아), "lie down" (누워), and four other words. He makes the sounds by putting his trunk in his mouth and shaking it while exhaling, similar to the way a human whistles with fingers in their mouth. Kwon Su-wan, director of the zoo in Seoul, said: "We plan to conduct further studies with keepers, veterinarians and scientists on whether Kosik understands the meaning of these words as he speaks them." Like most cases of talking animals, claims are subject to the observer-expectancy effect, which may be a meaningless form of mimicry and which are subject to fabrication for many reasons.

Worked examples

Example 1 — a first encounter with Kosik (elephant)

Start with the simplest possible case. Write down what Kosik (elephant) 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 Kosik (elephant) 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 Kosik (elephant) 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 Kosik (elephant)

In research: Kosik (elephant) 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 Kosik (elephant) 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: Kosik (elephant) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1990 animal births, 2006 in South Korea, Elephants in South Korea, so understanding it makes those chapters shorter.
In everyday life: Look for Kosik (elephant) 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.
