the concept of invariance

Invariance refers to the property of a system or object remaining unchanged or consistent under certain transformations or conditions. For example, a square looks like a square whether you rotate it, move it, or flip it. Invariance means that despite these changes, the essential features stay the same. In science and mathematics, this concept helps us understand patterns and rules that stay consistent across different situations, making them reliable and predictable. It’s a way to identify what qualities truly define something, regardless of how it’s viewed or experienced.
