What is the most motivating way to introduce group theory to first year undergraduate students? I am looking for some real life motivation or something which has a real impact.
Reflections, rotations, subtraction, division, solvability of algebraic equations, symmetries, the clock on the wall, isomorphisms, equivalence classes, greatest common divisor, least common multiple, ... etc. without groups there are no vector spaces, rings, fields, algebras, and large parts of physics.matqkks said:What is the most motivating way to introduce group theory to first year undergraduate students?

Group theory is a branch of mathematics that deals with the study of symmetries and transformations. It involves the study of groups, which are mathematical structures consisting of a set of elements and a binary operation that combines any two elements to form a third element. Group theory has many real-world applications, including in physics, chemistry, and cryptography.
Group theory has a wide range of applications in various fields. For example, in physics, group theory is used to describe the symmetry of physical systems and predict the behavior of particles. In chemistry, group theory is used to understand molecular structures and chemical reactions. In cryptography, group theory is used to develop secure encryption algorithms.
Some key concepts in group theory include group operations, subgroups, cosets, conjugacy classes, and group actions. Group operations refer to the binary operation that combines two elements in a group to form a third element. Subgroups are subsets of a group that also form a group under the same operation. Cosets are subsets of a group that represent the different ways of partitioning the group. Conjugacy classes are subsets of a group that contain elements that are related by a similarity transformation. Group actions refer to the way a group acts on a set of objects.
Learning group theory can help first-year students develop critical thinking, problem-solving, and abstract reasoning skills. It can also help them understand and appreciate the beauty and elegance of mathematics. Additionally, group theory has many real-world applications, which can help students see the practical relevance of their mathematical studies.
There are many resources available for first-year students to learn group theory, including textbooks, online courses, and lectures. Some recommended textbooks for beginners include "Group Theory: An Intuitive Approach" by R. Mirman and "A Book of Abstract Algebra" by Charles C. Pinter. Online resources such as Khan Academy and Coursera offer free courses on group theory. Additionally, many universities offer introductory courses on group theory as part of their mathematics curriculum.
