Portuguese inventions

Portuguese inventions 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 Portuguese inventions rather than just read about it. In short: The Portuguese inventions are the inventions created by the people born in Portugal (continent or overseas), or whose nationality is Portuguese. These inventions were created mainly during the age of Portuguese discoveries, and during modernity.

Key takeaways

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

Reference excerpt

The Portuguese inventions are the inventions created by the people born in Portugal (continent or overseas), or whose nationality is Portuguese. These inventions were created mainly during the age of Portuguese discoveries, and during modernity. Relying on trade secret explains, in part, the difficulty often experienced by researchers in documenting Portuguese inventions, as many are not described in patent documents, or other technical documents. On the other hand, there are cases, like some types of swords, where the inventions themselves or the underlying documents were lost, having been destroyed, for example, during the French invasions. There are as well documentation and objects of Portuguese origin in private collections or museums outside of Portugal.

Discoveries

The creation of new inventions in Portugal was at its peak during the Age of Discovery. These inventions consisted mainly in the improvement of devices and techniques of ocean navigation and coastal cartography, such as the mariner's astrolabe and the chart of latitudes. On the field of military applications, the construction of cannons and new types of swords, like the Carracks black sword.

Modernity More recently, the technical domain varies from computers to medicine. Such examples might be Via Verde, an automatic system for collecting tolls for vehicles; the Multibanco, an automatic teller machine network with a multitude of functions ranging from bank transfers to the payment of tickets for shows; or in the field of medicine, a treatment of epilepsy, the drug Zebinix by Bial Laboratories.

Worked examples

Example 1 — a first encounter with Portuguese inventions

Start with the simplest possible case. Write down what Portuguese inventions 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 Portuguese inventions 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 Portuguese inventions 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 Portuguese inventions

In research: Portuguese inventions 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 Portuguese inventions 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: Portuguese inventions is common in secondary-school and first-year university syllabi. It links to neighbouring topics Lists of inventions or discoveries, Portuguese inventions, so understanding it makes those chapters shorter.
In everyday life: Look for Portuguese inventions 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.
