Reference excerpt

Ruy López Ridaura is a Mexican epidemiologist, author and infectious diseases expert who has served as head of the National Center for Disease Control and Preventive Programs of the Secretariat of Health of Mexico. Since January 2020, he has been one of the lead members of the task force addressing the COVID-19 pandemic in Mexico.

Career

Education López Ridaura attended the School of Medicine of the National Autonomous University of Mexico (UNAM) graduating in 1994 as Physician-Surgeon. At that time he has been friend of Hugo López-Gatell. Afterwards, he obtained a master's degree in Clinic Epidemiology at UNAM in 2000, and later a Ph.D degree in nutritional epidemiology from the Harvard T.H. Chan School of Public Health.

Public service From 1998 to 2000 he was a physician at Salvador Zubirán National Institute of Health Sciences and Nutrition (INCMNSZ). From 2005 to 2007 López Ridaura was responsible for the Chronic Diseases Study Division at the National Institute of Public Health (INSP). From 2007 he is head and lead researcher of the Research Unit in Diabetes and Cardiovascular Risk at the same institute. Since 2007 he is director and main researcher of the Study of the Health of Teachers (in Spanish: Cohorte Esmaestras) project, a long-term project dedicated to the study of the development of chronic diseases in female Mexican teachers. From 2013 to 2014 he was a visiting researcher at the research institute of the Hospital Universitario La Paz in Spain. As a teacher López Ridaura is a member of the faculties of INSP and INSSZ. In 2020 he joined the task force addressing the COVID-19 pandemic in Mexico. He has conducted the daily press conference where the Secretariat of Health directives are giving information about the pandemic.

Worked examples

Example 1 — a first encounter with Ruy López Ridaura

Start with the simplest possible case. Write down what Ruy López Ridaura 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 Ruy López Ridaura 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 Ruy López Ridaura 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 Ruy López Ridaura

In research: Ruy López Ridaura 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 Ruy López Ridaura 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: Ruy López Ridaura is common in secondary-school and first-year university syllabi. It links to neighbouring topics 20th-century Mexican medical doctors, 21st-century Mexican medical doctors, Harvard T.H. Chan School of Public Health alumni, so understanding it makes those chapters shorter.
In everyday life: Look for Ruy López Ridaura 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.
