This lecture covers the basics of thermal conduction, including conductive heat transfer, Fourier's law, and thermal resistance. It also discusses the concept of local thermodynamic equilibrium, the analogy between Fourier's law and Ohm's law, and the one-dimensional heat equation. Furthermore, it explores the resistance network, the influence of conductive-convective phenomena, and the formation of boundary layers. The lecture concludes with a brief overview of the program 'MOOCS for Africa' developed by EPFL in collaboration with various partners.
