Reference excerpt

Pierre-Fernand Ceccaldi (29 November 1917 – 15 December 2006) was a French scientist and academic.

Biography Born in Jaulnat-Clan (Vienne departement), he pursued studies in the 1940s, earning degrees in both medicine and pharmacy. His interest in biology, especially histology, led him to the Ministry of the Interior, where he served as the head of the scientific police laboratory in Paris from 1957 to 1987. He also served as a professor at the Paris V University. During his career, Ceccaldi was involved in the integration of various scientific techniques into criminal investigations, covering areas such as biology, ballistics, photography, and electron microscopy. He frequently provided expert testimony in criminal cases. Ceccaldi's retirement aligned with the emergence of genetic fingerprinting in forensic science. In 1982, Ceccaldi established the Association for the Identification of Disaster Victims. He also authored several books, including Criminalistics and Legal Medicine for Judicial Use.

Worked examples

Example 1 — a first encounter with Pierre-Fernand Ceccaldi

Start with the simplest possible case. Write down what Pierre-Fernand Ceccaldi 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 Pierre-Fernand Ceccaldi 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 Pierre-Fernand Ceccaldi 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 Pierre-Fernand Ceccaldi

In research: Pierre-Fernand Ceccaldi 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 Pierre-Fernand Ceccaldi 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: Pierre-Fernand Ceccaldi is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1917 births, 2006 deaths, Academic staff of Paris Descartes University, so understanding it makes those chapters shorter.
In everyday life: Look for Pierre-Fernand Ceccaldi 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.
