Reference excerpt

Leonardo Krys (1944–2009) was a travel agent whose 1991 heart attack aboard a Lufthansa flight prompted U.S.-based airlines to install Automated External Defibrillators, or AED, on their planes.

Heart attack On November 30, 1991, Krys boarded a Lufthansa 747 in Miami, headed to Frankfurt, Germany. About an hour out, he suffered the symptoms of a cardiac infarction. The crew did not make an unscheduled landing and landed in Germany after a 10 hours flight. Upon landing, the plane was met by an ambulance which transported Krys to a hospital. At the hospital, the doctors concluded that Krys had indeed suffered a heart attack. Krys and his wife argued that Lufthansa's crew acted negligently in responding to the symptoms displayed by Mr. Krys and thus aggravated the damage to his heart. They won a lawsuit against Lufthansa in Miami federal court which the 11th Circuit Court of Appeals upheld. Later the United States Supreme Court refused to hear the airline's appeal arguing that the incident should have been classified as an accident, per the Warsaw Convention, capping his payout. The result of this suit prompted the airlines to review their safety manuals, including portable defibrillators and training the crew on how to use them.

Life Leo (as he was known by his friend and family) was born in Argentina, and moved with his family to Miami, USA in the late 1970s, due to the local economical and political situation. He owned a travel agency at the time of the heart attack, but the health crisis spurred a midlife career switch to acting. He acted in Telemundo telenovelas, local theater, an episode of America's Most Wanted (as an Israeli searching for his son's killer), several independent films and in Latin pop star La India's video, Traicion, as a priest. One of Krys' son, Sebastian, is a four-time American Grammy winner and eight-time Latin Grammy Awards producer and mixer (as of 2011) Leonardo Krys died of a heart attack in Miami, on March 14, 2009.

Worked examples

Example 1 — a first encounter with Leonardo Krys

Start with the simplest possible case. Write down what Leonardo Krys 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 Leonardo Krys 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 Leonardo Krys 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 Leonardo Krys

In research: Leonardo Krys 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 Leonardo Krys 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: Leonardo Krys is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1944 births, 2009 deaths, Cardiac electrophysiology, so understanding it makes those chapters shorter.
In everyday life: Look for Leonardo Krys 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.
