This was especially vexing to physician and bacteriologist Robert Koch, who, in seeking to culture his bacteria, “bent all his power to attain the desired result by a simple and consistently successful method,” wrote bacteriologist and historian William Bulloch in his 1938 book, The History of Bacteriology. “He attempted to obtain a good medium which was at once sterile, transparent, and solid” and got some results with gelatine.6 But gelatine is easily digested by many microbes and melts at precisely the temperatures at which the disease-causing microbes Koch wanted to study grow best.
保持一致的家庭原则：目前看来，教育孩子最忌讳的就是人多嘴杂，在各种问题上出现「分歧」。所以要进一步保持一致。教育孩子一个人张嘴，其他人要不闭嘴要不打好配合，绝对不能互相拆台。大人的问题，大人私下沟通，绝不在孩子面前争吵，给孩子一个温暖、和谐、快乐的成长环境。
