"In this thesis the problem of varying heat flux into a semi-infinite solid initially at zero temperature is investigated. Varying heat flux means that the heat transferred to the solid by its surroundings is a function of time; in this particular problem it is chosen to be an exponential function of time. A semi-infinite solid is one which is bounded by only one plane.

This subject has achieved considerable importance in the field of space technology. A body in space is beyond the realm of aerodynamic heating and non-uniform skin temperatures reached as a result of radiation from a high temperature source or to low temperature surroundings are largely a matter of conjecture.

The study of temperature stresses due to non-uniform heat flow is also important. Solutions to this type of problem are presently based on an estimated initial surface temperature and its variation with time rather than on the promise of the exterior heat flow itself.

It is the purpose of this thesis, then, to aid in the prediction of temperatures within a semi-infinite solid as a function of time and heat flux, without regard to the type of heat flow to the solid or the surface temperature"--Introduction, page 1.
