The terms "complex" and "complicated" are often used interchangeably, but they have distinct meanings, especially in technical or academic contexts:

Complex

• Definition: Something that is made up of many interconnected parts or systems that work together in intricate ways.
• Nature: Complex systems have an underlying structure, pattern, or organization, even if it is not immediately obvious.
• Example: A living organism like the human body is complex. It has numerous interacting systems (nervous, circulatory, digestive, etc.), and each part plays a role in the whole.
• Key Idea: Complexity arises from interdependence and adaptability. In a complex system, small changes in one part can ripple through and affect other parts, but there are often predictable patterns.
