Lake Tianchi Monster

Lake Tianchi Monster 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 Lake Tianchi Monster rather than just read about it. In short: Lake Tianchi Monster is the name given to what is said to be a lake monster that lives in Heaven Lake (known as Cheonji in Korean) located in the peak of Baekdu Mountain within the Baekdu-daegan and Changbai mountain ranges encompassing Jilin Province of China and Ryanggang Province of North Korea. According to Beijing Youth Daily, an estimated 20 monsters were reported; however, "scientists are skeptical that any l…

Key takeaways

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

Reference excerpt

Lake Tianchi Monster is the name given to what is said to be a lake monster that lives in Heaven Lake (known as Cheonji in Korean) located in the peak of Baekdu Mountain within the Baekdu-daegan and Changbai mountain ranges encompassing Jilin Province of China and Ryanggang Province of North Korea. According to Beijing Youth Daily, an estimated 20 monsters were reported; however, "scientists are skeptical that any large creature would be able to survive in the lake given its recent history of volcanic activity", and skeptics say "it's all in the imagination, or just a floating volcanic rock".

Sightings The first reported sighting was in 1903. It was claimed that a large buffalo-like creature attacked three people, but was shot six times. The monster then retreated under the water. In 21 to 23 August 1962, a person using a telescope reportedly saw two of the monsters chasing each other in water. More than a hundred people reported the sightings. More recent reports describe the monster as having a human-like head attached to a 1.5-meter (5 ft) neck. It is said to have a white ring around the bottom of its neck, and the rest of its skin is grey and smooth. In 2007, Zhuo Yongsheng, a Chinese TV reporter said he had shot a 20-minute video of six unidentified creatures in the volcanic lake on 6 September. He later sent still photos to Xinhua's Jilin provincial bureau. According to a news report one of these showed the six "Nessies" swimming in parallel in three pairs. Another one of them featured the animals closer together, leaving circular ripples on the lake surface. Zhuo said he had seen the six seal-like, finned creatures swimming and frolicking in the lake for an hour and a half, before they disappeared around 7:00 a.m. "They could swim as fast as yachts and at times they would all disappear in the water. It was impressive to see them all acting at exactly the same pace, as if someone was giving orders," he said. "Their fins—or maybe wings—were longer than their bodies."

In popular culture The Mountain Goats' 2008 album, Heretic Pride features the song, "Tianchi Lake" about the monster: "Backstroking on the surface, moonlight on its face / Floats the Tianchi monster, staring into space."

Worked examples

Example 1 — a first encounter with Lake Tianchi Monster

Start with the simplest possible case. Write down what Lake Tianchi Monster 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 Lake Tianchi Monster 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 Lake Tianchi Monster 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 Lake Tianchi Monster

In research: Lake Tianchi Monster 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 Lake Tianchi Monster 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: Lake Tianchi Monster is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chinese legendary creatures, Korean legendary creatures, Lake monsters, so understanding it makes those chapters shorter.
In everyday life: Look for Lake Tianchi Monster 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.
