Stéphane Dumas (astrophysicist)

Stéphane Dumas (astrophysicist) 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 Stéphane Dumas (astrophysicist) rather than just read about it. In short: Stéphane Dumas (1970–2016) was a Canadian physicist who, together with his colleague Yvan Dutil, has created a noise-resistant coding system for messages aimed at communicating with extraterrestrial civilization. This system was used in the creation of messages beamed towards close stars from the Yevpatoria RT-70 radio telescope in Ukraine in 1999 and 2003.

Key takeaways

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

Reference excerpt

Stéphane Dumas (1970–2016) was a Canadian physicist who, together with his colleague Yvan Dutil, has created a noise-resistant coding system for messages aimed at communicating with extraterrestrial civilization. This system was used in the creation of messages beamed towards close stars from the Yevpatoria RT-70 radio telescope in Ukraine in 1999 and 2003. Stéphane Dumas completed bachelor's degree in physics at the Université Laval in 1992. He also completed a master's degree in physics at the same institution in 2009. The topic of is dissertation was the detection by diffuse reflectance in infrared of endolithic colony. The objective was to be able to detect life inside rock in a non-destructive way, since in Mars analogue environment, half of the biomass lay in its hidden form. His supervisors were Gilles Joncas and Yvan Dutil. This was the first master's degree in astrobiology at the Université Laval and one of the first in Québec. In addition to his participation the Cosmic Call project, he was an active member of the IAA SETI Committee. He has been involved in many public debates on the risk related to active SETI, especially with David Brin. More recently, he has been carried some research on history of SETI. Also, he has worked with Claudio Maccone on the application of the Karhunen–Loève transform (KLT) for SETI observations. He also wrote Guest Editorials for The SETI League website and has long served as a SETI League volunteer Regional Coordinator. He was also the president of the Quebec Centre of the Royal Astronomical Society of Canada from 2006 to 2013. For the most of his career, he has worked as a computer scientist at the RDDC Valcartier on weapons effect simulation. He suddenly died in his home, on 9 June 2016, apparently as an indirect consequence of influenza.

Worked examples

Example 1 — a first encounter with Stéphane Dumas (astrophysicist)

Start with the simplest possible case. Write down what Stéphane Dumas (astrophysicist) 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 Stéphane Dumas (astrophysicist) 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 Stéphane Dumas (astrophysicist) 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 Stéphane Dumas (astrophysicist)

In research: Stéphane Dumas (astrophysicist) 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 Stéphane Dumas (astrophysicist) 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: Stéphane Dumas (astrophysicist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1970 births, 2016 deaths, 21st-century Canadian astronomers, so understanding it makes those chapters shorter.
In everyday life: Look for Stéphane Dumas (astrophysicist) 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.
