Explain the reduction as one of the prinicipal thrusts in physics .

Explanation

### Step-by-Step Solution

1. **Understanding Reductionism**:
- Reductionism is a philosophical approach in physics that aims to understand complex systems by breaking them down into their simpler, constituent parts.
- It posits that the properties of a complex system can be explained by the properties and interactions of its simpler components.

2. **Application of Reductionism**:
- In physics, reductionism allows scientists to analyze and understand larger phenomena by studying the fundamental laws and behaviors of smaller entities.
