## Study Notes

### Major Subdisciplines of Modern Mathematics

- Pure mathematics: focuses on the development of mathematical theories and models for their own sake
- Applied mathematics: uses mathematical theories and models to solve real-world problems

### Proofs in Mathematics

- Consist of a series of logical statements based on axioms and previously proven results
- Intended to establish the truth of a mathematical statement or theorem

### Mathematical Activity

- Primary method: deductive reasoning, using logical arguments to arrive at conclusions
- Involves formulating conjectures, testing hypotheses, and refining theories

### Objects of Mathematical Study

- Numbers, geometric shapes, algebraic structures, and other mathematical objects
- Relations, functions, and transformations between these objects
- Properties, patterns, and structures of these objects

### Nature of Mathematical Axioms

- Self-evident truths or fundamental principles that serve as the foundation of a mathematical theory
- Accepted as true without proof, serving as the basis for subsequent theorems and proofs

### Roentgen

- Definition: a unit of measurement for the biological effect of ionizing radiation
- Measures the amount of ionizing radiation required to produce a certain biological effect
- Equivalent to 2.58 x 10^-4 Coulombs per kilogram of air

### Applications of Roentgen

- Commonly used in radiation therapy and radiation protection in the field of medicine
