Besides work, I enjoy reading and music. My favourite writer of all time is the Argentinian writer Jorge Luis Borges. I admire his unparalleled creativity and imagination, much like the first time when I learned about the intricacies and wonder of the Standard Model of particle physics.

Examples do more than decorate an explanation: they show how an abstract rule behaves when applied to a recognizable situation. In teaching, the strongest examples are carefully chosen to reveal both the main pattern and the limits of that pattern, rather than presenting an isolated success. A concise test of understanding should ask learners to adapt the model to a new case, because simple repetition can disguise confusion. Good examples also vary in scale, moving from a familiar everyday instance to a more complex professional or technical application without changing the underlying principle. Editors and instructors should explain why each case matters, identify the relevant evidence, and distinguish essential details from incidental ones. Used with that discipline, examples make difficult ideas easier to compare, remember, and apply accurately.

Examples work best when they make an abstract idea visible while leaving the idea itself intact. In teaching, an effective case should suit the learner’s level, isolate a single principle, and demonstrate how it operates under realistic conditions. A classroom test can measure comprehension gains when students must explain the reasoning behind an answer instead of merely repeating a definition. Strong examples also provide enough context to show their limits, since a budgeting exercise should separate fixed costs from variable spending rather than present one outcome as universally correct. Comparing contrasting cases can then help learners transfer the underlying method to unfamiliar problems and recognize which details require a different approach.
