The Introduction sets the stage for ‘Computational Mineral Physics’, providing a concise overview of key topics. We start with the Earth’s internal structure, highlighting its core, mantle, and crust. Next, we touch on thermodynamic concepts like enthalpy, free energy, and the phase rule, crucial for interpreting phase diagrams. “Some Notions of Crystallography” introduces symmetry, direct and reciprocal space, and their significance in crystal structure analysis. Tensors are briefly discussed, essential for studying anisotropic properties. Last, we mention basic Linux/Unix commands for efficient data handling.
