Reference excerpt

Piz Buin is the trading name of a sunscreen firm, whose headquarters is in Zug, Switzerland. It is named after Piz Buin, a 3312-metre-high mountain in the Eastern Alps. The Piz Buin brand traces its origin back to the inspiration of Franz Greiter, a young chemistry student, who suffered severe sunburn while climbing Piz Buin in 1938. In 1946, Swiss chemist Franz Greiter introduced what may have been the first effective modern sunscreen. The product, called Gletscher Crème (Glacier Cream), subsequently became the basis for the company Piz Buin, which is still today a marketer of sunscreen products, named in honor of the mountain where Greiter allegedly obtained the sunburn that inspired his sunscreen. In 1974, Greiter adapted earlier calculations from Friedrich Ellinger and Rudolf Schulze and introduced the "sun protection factor" (SPF), which has become a worldwide standard for measuring the effectiveness of sunscreen. It has been estimated that Gletscher Crème had an SPF of 2.

Worked examples

Example 1 — a first encounter with Piz Buin (brand)

Start with the simplest possible case. Write down what Piz Buin (brand) 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 Piz Buin (brand) 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 Piz Buin (brand) 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 Piz Buin (brand)

In research: Piz Buin (brand) 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 Piz Buin (brand) 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: Piz Buin (brand) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Brand name products stubs, Personal care brands, Sunscreen brands, so understanding it makes those chapters shorter.
In everyday life: Look for Piz Buin (brand) 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.
