The warmth of floors—a physical study*

It is commonly believed that a concrete floor feels cold, whereas a wood floor feels warm. It is not clear however, under what conditions this statement is supposed to be valid, if, in fact, it is true at all. Nevertheless, one supposes that it applies certainly to walking barefoot across the floor; and it is believed by many to apply also when shoes are worn. In common usage, however, no attempt is made to eliminate the factor of surface temperature.
