Abstract

(An invited address delivered on the occasion of the commemoration of the 100th anniversary of the Iowa Academy of Science.)

Materials are essential for the support of human life. At the primitive level they provide food, shelter and protection against the natural elements. At the advanced level of the technological civilization of the 20th century they support the luxuries to which we have become accustomed-and which we insist upon calling our "needs." Today they are essential to our industry, our economy and our national security.
