Mathematics is often considered the only true and immutable science because its principles and laws are based on logical reasoning and deductive proofs, rather than empirical observations. This means that mathematical truths are not subject to change based on new discoveries or interpretations, unlike other sciences which may be influenced by new evidence or theories. Additionally, mathematics provides a universal language and framework for understanding the natural world, making it a fundamental and unchanging tool for describing and predicting phenomena in other scientific disciplines. Therefore, mathematics is often seen as the most pure and unchanging science, providing a foundation for all other scientific knowledge. **
