Study Notes
- Mathematics is the study of topics such as quantity (numbers), structure, space, and change.
- It has no generally accepted definition.
- Mathematicians seek out patterns and formulate new conjectures.
- They resolve the truth or falsity of conjectures by mathematical proofs.
- Mathematics is used throughout the world as an essential tool in many fields, including natural science, engineering, medicine, finance, and social sciences.
- Applied mathematics concerns itself with the use of mathematical tools to solve problems in natural sciences, engineering, medicine, finance, business, computer science, and social sciences.
- Mathematics is used to model real-world phenomena.
- Statistics is concerned with the collection, analysis, interpretation, and presentation of data.
- Computational mathematics includes numerical analysis, symbolic computation, and computer algebra.
History of Mathematics
- The history of mathematics is an ever-growing series of abstractions.
- The concept of abstract numbers and the practice of determining the area of a field were developed early in mathematics.
- The oldest mathematical texts available are from ancient Egypt and Mesopotamia.
- Rigorous proof first appeared in Greek mathematics.
- Mathematics developed at a relatively slow pace until the Renaissance, when mathematical innovations interacting with new scientific discoveries led to a rapid increase in the rate of mathematical development.
- The development of infinitesimal calculus by Newton and Leibniz in the 17th century revolutionized mathematics.
- Leonhard Euler made numerous contributions to notation, terminology and mathematical formulas.
Areas of Mathematics
Quantity
- Quantity begins with numbers, first the familiar natural numbers (1, 2, 3, ...).
- Next are integers which include negative numbers (-1, -2, -3, ...).
- Rational numbers arise as quotients of natural numbers (e.g., 3/4).
- Real numbers are all numbers that can be represented by a decimal, and include both the rational numbers and the irrational numbers.
- Complex numbers allow solutions to equations that have no solutions in real numbers.
- Hypercomplex numbers extend the complex numbers.
- The study of numbers is number theory, and includes Fermat's Last Theorem.
Structure
- Many mathematical objects, such as sets of numbers and functions, exhibit internal structure as a consequence of operations or relations that are defined on the set.
- Abstract algebra is the study of algebraic structures, such as groups, rings, and fields.
- Vector spaces are used in linear algebra.
- Analysis studies structures that include a notion of closeness.
Space
- Space is studied in geometry.
- Trigonometry studies the relationships between the sides and angles of triangles.
- Differential geometry studies curves and surfaces.
- Topology studies properties that are invariant under continuous transformations.
Change
- Understanding and describing change is a common theme in the natural sciences.
- Calculus was developed to investigate change.
- Functions arise here, as central to describing a changing quantity.
- Differential equations describe the relationship between a function and its derivatives.
- Chaos theory deals with dynamical systems that exhibit significant sensitivity to initial conditions.
Foundations and Philosophy
- In order to clarify the foundations of mathematics, the fields of mathematical logic and set theory were developed.
- Mathematical logic deals with putting mathematics on a solid axiomatic framework, and studies the implications of that framework.
- Set theory is the branch of mathematics that studies sets or collections of objects.
- Category theory deals in an abstract way with mathematical structures and relations between them.
Discrete Mathematics
- Discrete mathematics groups together the fields of mathematics which deal with discrete objects.
- Combinatorics studies ways of enumerating certain objects.
- Graph theory studies graphs and networks.
Mathematical Notation, Language, and Rigor
- Most of the mathematical notation in use today was not invented until the 16th century.
- Before that, mathematics was written out in words.
- Mathematical notation makes mathematics easier for the professional to manipulate, but beginners often find it daunting.
- A mathematical proof is sufficient to convince other mathematicians of the truth of the statement.
- The need for mathematical rigor led to the development of mathematical logic and set theory.
- Mathematical rigor differs somewhat from rigor in other sciences.
Pure and Applied Mathematics
- Pure mathematics is mathematics that is developed primarily for its own sake.
- Applied mathematics is mathematics with substantial applications in other areas.
- Many branches of mathematics that began as pure mathematics have later become applied mathematics.
- Applied mathematics is often used to solve practical problems.
- There is no sharp division between pure and applied mathematics.
