1921年至1922年间在加拿大多伦多大学发现了胰岛素(insulin),从而导致了医学史上发生了一场革命。长期以来,人们一直以为这一发现是一位年青加拿大医生卓越想法的结果,事实上并非如此简单。60年后科学史学家们进行了广泛的仔细研究,查阅当时未曾发表的文件、实验记录,再现了整个胰岛素的发现历程,其中包括既有成功又有失败的日常实验工作、决定实验成功的关键步骤以及实验背景和研究人员的合作情况,发现工作进展并不是 The discovery of insulin from 1921 to 1922 at the University of Toronto in Canada led to a revolution in medical history. It has long been assumed that this finding is the result of a remarkable idea by a young Canadian doctor, and in fact it is not that simple. Sixty years later, historians of science conducted extensive and careful studies, reviewing unpublished documents and experimental records that were then available, and reproducing the entire insulin discovery process, including both routine and unsuccessful experimental work and the key to successful experimentation Steps and experimental background and the cooperation of researchers, found that the progress of the work is not
