			In various fields, the term [[Magic number]] refers to a specific value or quantity that holds particular significance due to its unique properties, frequent occurrence, or role in defining systems, phenomena, or processes. While the concept appears across disciplines, its meaning and implications vary depending on context. Below is an overview of its applications and interpretations.

			{{H2\|In Computing and Programming}}
			In software development, a [[Magic number]] often denotes a hard-coded numeric value embedded directly into source code without clear documentation or abstraction. These values are typically criticized for reducing code readability and maintainability, as their purpose may not be immediately apparent to other developers. For example, using the number `31` as a hash table size or `42` as a placeholder in debugging code are common instances. Best practices in programming advocate replacing such values with named constants to improve clarity and facilitate future modifications. This practice is discussed in detail in resources on software engineering principles.

			{{H2\|In Mathematics and Physics}}
			In mathematics and physics, [[Magic number]] can describe numbers with special properties or roles. For instance, in nuclear physics, the "magic numbers" 2, 8, 20, 28, 50, 82, and 126 represent the number of protons or neutrons in atomic nuclei that result in particularly stable configurations. These values correspond to filled shells in the nuclear shell model, analogous to electron shells in atomic structure. Similarly, in mathematics, numbers like the [[Golden ratio]] (approximately 1.618) or [[Euler's number]] (approximately 2.718) are sometimes informally referred to as "magic" due to their recurring appearances in nature, art, and equations.

			{{H2\|In Popular Culture and Metaphor}}
			Beyond technical contexts, the term [[Magic number]] is occasionally used metaphorically to describe thresholds or pivotal values in non-scientific domains. For example, in business, a "[[Magic number]]" might refer to a revenue target or key performance indicator that determines success or failure. In sports analytics, it could denote a statistically significant metric for evaluating player performance. These uses are generally informal and context-dependent.

			- [[Nuclear shell model]]
			- [[Golden ratio]]
			- [[Euler's number]]
