1. What Is Cohesion? A Straightforward Definition

Defining Cohesion

Cohesion is the quality or state of sticking together and forming a unified whole. It refers to both the physical forces that hold molecules together and the abstract bonds that unite groups, communities, or ideas. In essence, cohesion is the glue that binds separate parts into a coherent system.

Essential Characteristics of Cohesion

When we ask, what is cohesion, several key properties come to mind:

• Adhesion and Attraction:
  In physical terms, cohesion describes the attractive forces between like molecules. For instance, water molecules stick together due to hydrogen bonding, which is why droplets form.

• Unification:
  Cohesion results in a state of unity where individual elements maintain their identity while contributing to the overall integrity of the group or structure.

• Stability and Resilience:
  A system with strong cohesion tends to be stable and resistant to external disruptions. This can be observed in both materials (such as the strength of a metal) and groups (such as a cohesive team that overcomes challenges).

• Interconnectivity:
  Cohesion implies a level of interconnectedness, where the relationships among components are strong enough to maintain the whole even if individual parts are altered.

• Dynamic Balance:
  Although cohesion brings elements together, it also allows for a dynamic balance. In a cohesive group, for example, individual contributions can vary while the overall unity remains intact.

Understanding these characteristics is crucial because they lay the foundation for analyzing cohesion across different contexts—whether in the physical sciences or in social systems.

2. Historical and Contextual Background
