Wilhelm Hisinger

Wilhelm Hisinger is a physics 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 Wilhelm Hisinger rather than just read about it. In short: Wilhelm Hisinger (23 December 1766 – 28 June 1852) was a Swedish physicist and chemist who in 1807, working in coordination with Jöns Jakob Berzelius, noted that in electrolysis any given substance always went to the same pole, and that substances attracted to the same pole had other properties in common. This showed that there was at least a qualitative correlation between the chemical and electrical natures of bod…

Key takeaways

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

Reference excerpt

Wilhelm Hisinger (23 December 1766 – 28 June 1852) was a Swedish physicist and chemist who in 1807, working in coordination with Jöns Jakob Berzelius, noted that in electrolysis any given substance always went to the same pole, and that substances attracted to the same pole had other properties in common. This showed that there was at least a qualitative correlation between the chemical and electrical natures of bodies.

Career In 1803, in separate laboratories, Martin Heinrich Klaproth in one, and Berzelius and Hisinger in another, the element Cerium was discovered, which was named after the newly discovered asteroid, Ceres. It was discovered nearly simultaneously by both laboratories, though it was later shown that Berzelius and Hisinger's cerium was actually a mixture of cerium, lanthanum and so-called didymium. The element was first isolated by Carl Gustaf Mosander in 1838. Hisinger was elected a member of the Royal Swedish Academy of Sciences in 1804.

Death and legacy Hisinger died in 1852, aged 85. The mineral hisingerite, an iron silicate, with the formula Fe2Si2O5(OH)4·2H2O, is named after Hisinger. There is also Aluminian Hisingerite which is when one of the iron atoms is replaced by aluminum. The mountain of Hisingerfjellet in Nathorst Land at Spitsbergen, Svalbard, is named after him.

Worked examples

Example 1 — a first encounter with Wilhelm Hisinger

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

In research: Wilhelm Hisinger appears in physics 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 Wilhelm Hisinger 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: Wilhelm Hisinger is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1766 births, 1852 deaths, 18th-century Swedish chemists, so understanding it makes those chapters shorter.
In everyday life: Look for Wilhelm Hisinger 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.
