Tankero

Tankero 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 Tankero rather than just read about it. In short: The tankero was a fictional animal that was quite popular in Finnish media in the 1970s. The word comes from a popular Finnish joke, where the prime minister of Finland Ahti Karjalainen visited a Kenyan zoo in the 1970s.

Key takeaways

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

Reference excerpt

The tankero was a fictional animal that was quite popular in Finnish media in the 1970s. The word comes from a popular Finnish joke, where the prime minister of Finland Ahti Karjalainen visited a Kenyan zoo in the 1970s. Reportedly, he said "Kaikki eläimet ovat tankeroita" (Finnish for "All animals are tankeros"), after misunderstanding a sign that said, "All animals are dangerous." This was so popular that one Finnish magazine held a drawing competition of what the tankero would look like. The Finnish political cartoonist Kari Suomalainen drew a strip where Kalevi Sorsa meets Karjalainen and a strange-looking animal. "Is that a tankero?" asks Sorsa, and the strange-looking animal replies "No, that is Ahti." During the same period a certain number of jokes, based on English–Finnish language misunderstandings, were current - such as a person mistakenly greeting a Crimean by calling him criminal. These jokes were labelled as "tankero jokes" and generally told with Ahti Karjalainen as the main character. The original meaning fell into disuse after Karjalainen's death, and today it is a slang word for something awkward or not properly developed, abysmal knowledge of the pronunciation or grammar of a foreign language. The most common use of the word tankero today is "tankero-englanti" or "tankero English", meaning poorly pronounced English. The term has connotations of awkward-sounding pronunciation with an extreme Finnish accent. The actual grammar and vocabulary of "tankero English" may well be correct, though. The word tankero appears in the names of two Finnish songs. Juha Vainio recorded a song “Tankero tango” in 1974. The following year, “Tankeros love” performed by Kivikasvot was released.

Worked examples

Example 1 — a first encounter with Tankero

Start with the simplest possible case. Write down what Tankero 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 Tankero 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 Tankero 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 Tankero

In research: Tankero 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 Tankero 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: Tankero is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1970s establishments in Finland, 1970s neologisms, Fictional animals, so understanding it makes those chapters shorter.
In everyday life: Look for Tankero 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 Tankero in simple terms?

Why does Tankero matter?

Because it connects several science 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 Tankero?

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.
