Ywam Liberty

Ywam Liberty is a mathematics 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 Ywam Liberty rather than just read about it. In short: YWAM Liberty is the former L'Astrolabe, a French icebreaking research vessel which was used to supply the Dumont d'Urville research station in Antarctica. The vessel made regular voyages between Hobart and the Dumont D'Urville research station for fifteen years and was replaced by a new icebreaker bearing the same name in 2017.

Key takeaways

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

Reference excerpt

YWAM Liberty is the former L'Astrolabe, a French icebreaking research vessel which was used to supply the Dumont d'Urville research station in Antarctica.

The vessel made regular voyages between Hobart and the Dumont D'Urville research station for fifteen years and was replaced by a new icebreaker bearing the same name in 2017.

History

1992 Northeast Passage The vessel has also traversed the Northeast passage. The European Space Agency reports a 1992 traverse "was the first civilian expedition through the NSR since the Russian Revolution." L'Astrolabe was escorted on her transit by Russian icebreakers.

2013 Antarctic Ocean rescue mission L'Astrolabe attempted to reach Akademik Shokalskiy, trapped by an outbreak of old glacial ice in the Antarctic Ocean. L'Astrolabe didn't match Chinese research vessel Xue Long's 6 nautical miles (11 km; 6.9 mi) from the trapped Russian ship, but got closer than the Australian Aurora Australis' 10 nautical miles (19 km; 12 mi). Withdrawing after encountering heavy ice, she subsequently supported further attempts by Xuě Lóng and Aurora Australis to reach Akademik Shokalskiy and rescue her passengers.

2018 Deployment to Bougainville PNG as a Medical Ship From July 2018, YWAM Liberty spent six months in Bougainville, Papua New Guinea providing primary health, dental, optometry and ophthalmic care. The ship is administered by YWAM Ships Kona, from Kailua-Kona in Hawaii.

Incidents

2005 man overboard incident

On January 27, 2005, a crew member was found to have gone overboard. The missing crew member's body was found. During the recovery of his body the second engineer's hand was seriously injured, and he was at risk of losing his thumb. A report by the Australian Transport Safety Board concluded his injury would have been avoided if the block he was using to recover the ship's boat had been equipped with handholds. The report noted that the deceased crew member was found with a high blood alcohol level. He had been seen to be depressed prior to his death, and the report concluded he had jumped or fallen overboard under the influence of alcohol.

2010 Antarctica helicopter crash On October 28, 2010, a Eurocopter AS350 helicopter which operated between the ship and the Dumont d'Urville Station crashed in bad weather en route to the station. All 4 on board were killed.

Worked examples

Example 1 — a first encounter with Ywam Liberty

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

In research: Ywam Liberty appears in mathematics 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 Ywam Liberty 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: Ywam Liberty is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1986 ships, IMO numbers, Icebreakers of France, so understanding it makes those chapters shorter.
In everyday life: Look for Ywam Liberty 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.
