[ti:δ?] [ar:] [al:] [by:https://www.lrc.com.cn] [00:01.55]Lesson 15 [00:03.09]Secrecy in industry [00:10.53]Why is secrecy particularly important in the chemical industries? [00:18.87]2 factors [00:19.80]weigh heavily against the effectiveness of scientific research in industry. [00:25.38]One is the general atmosphere of secrecy in which it is carried out, [00:30.87]the other the lack of freedom of the individual research worker. [00:35.82]In so far as any inquiry is a secret one, [00:39.56]it naturally limits all those engaged in carrying it out [00:43.53]from effective contact with their fellow scientists [00:46.40]either in other countries or in universities, [00:50.00]or even,often enough,in other departments of the same firm. [00:55.55]The degree of secrecy naturally varies considerably. [00:59.93]Some of the bigger firms are engaged in researches [01:03.30]which are of such general and fundamental nature [01:06.45]that it is a positive advantage to them not to keep them secret. [01:12.31]Yet a great many processes depending on such research [01:16.14]are sought for with complete secrecy [01:18.99]until the stage at which patents can be taken out. [01:23.15]Even more processes are never patented at all but kept as secret processes. [01:29.70]This applies particularly to chemical industries, [01:33.46]where chance discoveries play a much larger part [01:36.87]than they do in physical and mechanical industries. [01:40.67]Sometimes the secrecy goes to such an extent [01:44.09]that the whole nature of the research cannot be mentioned. [01:48.15]Many firms,for instance [01:49.87]have great difficulty in obtaining technical or scientific books from libraries [01:55.05]because they are unwilling to have their names entered [01:57.87]as having taken out such and such a book, [02:00.70]for fear the agents of other firms should be able to trace the kind of research [02:05.86]they are likely to be undertaking.
