How science makes new materials out of old : 2-Textiles
Here is the second talk in a series which began last week and which is planned to show that there is much to be gaid for synthetic products, and that they by no means deserve the disparagement that sometimes attaches to them. It is admittedly bad that a nation should have to depend on substitutes, but the search for the substitute-the ersatz of Germanv-is the foundation of ail scientific progress. The so-called substitutes are often nothing of the kind, but new materials, and for some purposes are often better than products of nature. Each talk is being given by an expert in his particular line.
