Víctor Alberto Ramos

Víctor Alberto Ramos is a astronomy 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 Víctor Alberto Ramos rather than just read about it. In short: Víctor Alberto Ramos (born 1945) is an Argentine geologist who has contributed to the paleogeography and plate tectonics of South America. He has been a member of the Chilean Academy of Science since 2001 and won in 2013 the Premio México de Ciencia y Tecnología.

Key takeaways

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

Reference excerpt

Víctor Alberto Ramos (born 1945) is an Argentine geologist who has contributed to the paleogeography and plate tectonics of South America. He has been a member of the Chilean Academy of Science since 2001 and won in 2013 the Premio México de Ciencia y Tecnología. Ramos was the first to recognize the existence of Chilenia and the former sea that separated it from the rest of South America (then part of Gondwana). At the time of the discovery in the 1980s it was considered to be speculative. In a 1988 conference in Chile the discovery of Chilenia was not well received and a payador at the conference ridiculed him. As the existence of Chilenia was recognized, he was made a member of the Chilean Academy of Sciences. Together with other researchers Ramos has proposed to change the age of the Jurassic-Cretaceous boundary from 145 Ma to 140 Ma making the Jurassic longer. This proposal derives from a 2014 study based on biostratigraphy and radiometric dating of ash in the Vaca Muerta Formation in Neuquén Basin, Argentina. In Ramos' words the study would serve as a "first step" toward formally changing the age in the International Union of Geological Sciences. Ramos has proposed that the Patagonian landmass originated as an allochthonous terrane that separated from Antarctica and docked in South America 250 to 270 Ma in the Permian period. A 2014 study by Robert John Pankhurst and co-workers reject the idea of a far-travelled Patagonia claiming it is likely of parautochthonous (nearby) origin. Víctor Ramos has been a visiting professor at:

Universidade Federal de Ouro Preto, Brazil Cornell University, United States Universidad de Chile, Chile Universidad Nacional de Salta, Argentina Universidad Nacional de San Juan, Argentina Universidad Nacional de San Luis, Argentina Universidade Federal do Rio Grande do Sul, Brazil University of São Paulo, Brazil Universidad Nacional del Sur, Argentina Universidad Nacional de Córdoba, Argentina Universidad Nacional de Asunción, Paraguay Universidad de la República, Uruguay

Worked examples

Example 1 — a first encounter with Víctor Alberto Ramos

Start with the simplest possible case. Write down what Víctor Alberto Ramos claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Víctor Alberto Ramos 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 Víctor Alberto Ramos 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 Víctor Alberto Ramos

In research: Víctor Alberto Ramos appears in astronomy 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 Víctor Alberto Ramos 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: Víctor Alberto Ramos is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1945 births, Academic staff of the University of Buenos Aires, Academic staff of the University of Chile, so understanding it makes those chapters shorter.
In everyday life: Look for Víctor Alberto Ramos 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.
