Quantum mechanics in simple matrix form

This simple text makes basic quantum mechanics accessible with a minimum of mathematics. The focus is on the matrices representing physical quantities. States are described simply by mean values of physical quantities or by probabilities for possible values. This approach reveals the essential simplicity of quantum mechanics by focusing on basics and working only with key elements of mathematical structure. The book introduces all mathematics involved with using algebra of matrices, complex numbers, probabilities and mean values, and offers over 100 problems.
