PHARES

PHARES 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 PHARES rather than just read about it. In short: Phares (stylized PHARES) is a monumental interactive sculpture by Milène Guermont. This monument made of golden aluminium and light can be considered as a “beacon of headlights” (“phare de phares” in French).

Key takeaways

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

Reference excerpt

Phares (stylized PHARES) is a monumental interactive sculpture by Milène Guermont. This monument made of golden aluminium and light can be considered as a “beacon of headlights” (“phare de phares” in French). The first location of this 97-foot-high artwork was next to the Obelisk on Place de la Concorde in Paris (from October 2015 till April 2016) where the first public test of electric lighting in the world happened in 1843. Passers-by can transmit their heart rhythms directly into PHARES via a built-in sensor, and then see it sparkle as it replicates the heart beats in real-time. In February 2016, PHARES also interacted with the Eiffel Tower and the Montparnasse Tower that illuminate at the rhythm of the same heartbeat. It is labelled “COP21 / CMP11“ (21st session of the Conference of the Parties to the United Nations Framework Convention on Climate Change), “PARIS FOR THE CLIMATE” and by the international jury of “2015 international year of light“ launched by UNESCO.

Worked examples

Example 1 — a first encounter with PHARES

Start with the simplest possible case. Write down what PHARES 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 PHARES 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 PHARES 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 PHARES

In research: PHARES 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 PHARES 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: PHARES is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2015 in Paris, 2016 in Paris, Aluminium sculptures, so understanding it makes those chapters shorter.
In everyday life: Look for PHARES 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.

Frequently asked questions

What is PHARES in simple terms?

Why does PHARES matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study PHARES?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
