Serendipity

He who seeks, finds.
Sometimes, also he who does NOT seek, finds accidentally something curious, desirable, interesting though unexpected or out of place
especially while looking for something else.
Serendipity is the engine for a lot of discoveries.
Many discoveries continue indeed to be made by

• chance
• observation
• sagacity

these are the three fundamental elements of Serendipity that can be considered not only a method of research, but also a lifestyle.
