Reference excerpt

Jonas Asevicius-Acus-Acukas (July 29, 1885 in Jieznas – July 11, 1976 in Kaunas) was a Lithuanian army officer and chemist. From 1909 to 1918, he served in the Imperial Russian Army at Kaunas Fortress. He fought in the First World War and the Russian Civil War. In 1921 he returned to Lithuania and was mobilized into the Lithuanian Armed Forces, where he attained the rank of colonel (1927) and served until 1940. Acus graduated from Vytautas Magnus University in 1930. He lectured on chemistry and commodity science at Vytautas Magnus University (1934–1940), Vilnius University (1940–1950), and Lithuanian University of Agriculture (1951–1957). He wrote textbooks on foundations of commodity science (1949) and a short course in physical chemistry (1957). Acus was awarded the Commander's Crosses of the Order of Vytautas the Great (1938) and the Order of the Lithuanian Grand Duke Gediminas (1928).

Worked examples

Example 1 — a first encounter with Jonas Acus-Acukas

Start with the simplest possible case. Write down what Jonas Acus-Acukas claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, 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 Jonas Acus-Acukas 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 Jonas Acus-Acukas 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 Jonas Acus-Acukas

In research: Jonas Acus-Acukas appears in chemistry 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 Jonas Acus-Acukas 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: Jonas Acus-Acukas is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1885 births, 1976 deaths, Academic staff of Vilnius University, so understanding it makes those chapters shorter.
In everyday life: Look for Jonas Acus-Acukas 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.
