1. The quality or state of not being linear; deviation from a straight line or proportional relationship.
Usage: Plural form of nonlinearity; Commonly used in mathematics, physics, and engineering
2. In mathematics and science, a property of a system or function where output is not directly proportional to input.
Usage: Technical usage in scientific and mathematical contexts

Examples

• The engineer studied the nonlinearities in the bridge's structural response to wind.
• Nonlinearities in the climate system make long-term weather prediction extremely difficult.
• The physicist's model accounts for several nonlinearities that simpler theories ignore.
• These nonlinearities explain why the system behaves unpredictably at high temperatures.
• Understanding the nonlinearities in neural networks is crucial for improving artificial intelligence.
• The graph shows clear nonlinearities that cannot be explained by a simple linear equation.
