[00:01.54]Lesson 15 [00:03.45]Secrecy in industry [00:12.27]Why is secrecy particularly important in the chemical industries? [00:19.76]Two factors weigh heavily against the effectiveness of scientific research in industry. [00:26.40]One is the general atmosphere of secrecy in which it is carried out, [00:31.91]the other the lack of freedom of the individual research worker. [00:37.00]In so far as any inquiry is a secret one, [00:40.77]it naturally limits all those engaged in carrying it out from effective contact with their fellow scientists either in other countries or in universities, [00:51.08]or even, often enough, in other departments of the same firm. [00:56.75]The degree of secrecy naturally varies considerably. [01:01.11]Some of the bigger firms are engaged in researches which are of such general and fundamental nature [01:07.94]that it is a positive advantage to them not to keep them secret. [01:13.61]Yet a great many processes depending on such research are sought for with complete secrecy until the stage at which patents can be taken out. [01:24.58]Even more processes are never patented at all but kept as secret processes. [01:31.12]This applies particularly to chemical industries, [01:34.96]where chance discoveries play a much larger part than they do in physical and mechanical industries. [01:42.16]Sometimes the secrecy goes to such an extent that the whole nature of the research cannot be mentioned. [01:49.61]Many firms, for instance have great difficulty in obtaining technical or scientific books from libraries [01:56.64]because they are unwilling to have their names entered as having taken out such and such a book, [02:02.19]for fear the agents of other firms should be able to trace the kind of research they are likely to be undertaking.
