Science refers to natural science, applied science and mathematical logic, as opposed to liberal arts. Science subjects mainly include: mathematics, physics, chemistry, biology, geography, computer software application, technology and design practice.
Mathematics is a subject that studies concepts such as quantity, structure, change and spatial model. By using abstract and logical reasoning, the shape and motion of objects are counted, calculated, measured and observed. Mathematicians have extended these concepts in order to express new conjectures with formulas and establish strictly deduced truths from properly selected axioms and definitions.
