Žemaitkiemis meteorite

Žemaitkiemis meteorite 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 Žemaitkiemis meteorite rather than just read about it. In short: Žemaitkiemis meteorite is an ordinary chondrite that fell near Žemaitkiemis, Lithuania at about 8:33 pm on 2 February 1933. Using the argon–argon dating method, scientists have calculated its age to be about 520 million years.

Key takeaways

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

Reference excerpt

Žemaitkiemis meteorite is an ordinary chondrite that fell near Žemaitkiemis, Lithuania at about 8:33 pm on 2 February 1933. Using the argon–argon dating method, scientists have calculated its age to be about 520 million years.

The fall was observed by the Koenigsberg Observatory. Since the meteorite fell near inhabited areas during winter, it was rather easy to locate the fragments in the snow. In total, 20 fragments with a combined weight of 42.2 kilograms (93 lb) were collected and donated to the Vytautas Magnus University. The largest pieces weighted 7,258 and 7,080 grams (256.0 and 249.7 oz). Two other fragments were gifted later – 36.6 grams (1.29 oz) and 1,840 grams (65 oz) – to the Institute of Geology and Geography in Vilnius. There were also reports of a 10 kilograms (22 lb) fragment found about 3 kilometres (1.9 mi) from Žemaitkiemis in 1938. More pieces likely fell into the Kliepšiai Lake or were kept by the locals. The main mass, two largest fragments and 13 other fragments, are held by the Geology Museum of Vilnius University. Other fragments are held by: 2.1 kilograms (4.6 lb) by the National Museum in Prague, 1.1 kilograms (2.4 lb) by the Russian Academy of Science, 636 grams (22.4 oz) by the Natural History Museum in London, 69 grams (2.4 oz) by the National Museum of Natural History in Paris, 33 grams (1.2 oz) by the Field Museum of Natural History in Chicago, 13.9 grams (0.49 oz) by the Geological Survey of Canada, and others. On 14 July 2017, President Dalia Grybauskaitė approved a coat of arms of Žemaitkiemis that features the meteorite fall.

Worked examples

Example 1 — a first encounter with Žemaitkiemis meteorite

Start with the simplest possible case. Write down what Žemaitkiemis meteorite 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 Žemaitkiemis meteorite 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 Žemaitkiemis meteorite 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 Žemaitkiemis meteorite

In research: Žemaitkiemis meteorite 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 Žemaitkiemis meteorite 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: Žemaitkiemis meteorite is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1933 in Lithuania, 1933 in science, Chondrite meteorites, so understanding it makes those chapters shorter.
In everyday life: Look for Žemaitkiemis meteorite 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.
