1 - Intro and Conduction + Interpolation

Understand the basics of Fourier's Law of Thermal Conduction; Utilize your calculators for faster interpolation. Starting at 38:06, the unit for thermal conductivity should be BTU/hr-ft-F. I forgot to write hr that's why the final answer is only in BTU. With that, the unit for the final answer should be in BTU/hr.
