Salomon Coster

Salomon Coster 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 Salomon Coster rather than just read about it. In short: Salomon Coster (c. 1620–1659) was a Dutch clockmaker of the Hague, who in 1657 was the first to make a pendulum clock, which had been invented by Dutch mathematician Christiaan Huygens (1629-1695). Coster died a sudden death in 1659.

Key takeaways

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

Reference excerpt

Salomon Coster (c. 1620–1659) was a Dutch clockmaker of the Hague, who in 1657 was the first to make a pendulum clock, which had been invented by Dutch mathematician Christiaan Huygens (1629-1695). Coster died a sudden death in 1659. Christiaan Huygens invented the pendulum in December 1656 and Salomon Coster received the patent to create the clocks a year later. Coster's earliest pendulum clocks were signed "Samuel Coster - Haghe met privilege", indicating that he had been authorized by the inventor (Huygens) to make such clocks. This clock design was heralded as a new beginning in the clockmaking industry, due to its level of timekeeping accuracy which was previously unheard of. The oldest extant pendulum clock, signed by Coster in 1657, is on display at the Boerhaave Museum in Leiden, the Netherlands. Around the same time, John Fromanteel, the son of a London clockmaker named Ahasuerus, went to work for Coster. He was one of many foreign clockmakers to soon make pendulum clocks following the prototype by Huygens and Coster. A contract was signed on 3 September 1657 between Salomon Coster and John Fromanteel which allowed Fromanteel to continue making the clocks.

Worked examples

Example 1 — a first encounter with Salomon Coster

Start with the simplest possible case. Write down what Salomon Coster 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 Salomon Coster 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 Salomon Coster 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 Salomon Coster

In research: Salomon Coster 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 Salomon Coster 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: Salomon Coster is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1620s births, 1659 deaths, Christiaan Huygens, so understanding it makes those chapters shorter.
In everyday life: Look for Salomon Coster 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.
