It is entirely reasonable for auditors to believe that scientists who know exactly where they are going
and
how they will get there should not be distracted by the necessity of keeping one eye on the cash register
while
the other eye is on the microscope.
Distract:vt. 转移;分心 auditor:n. 审计员;旁听生;听者

[参考译文] 审查者完全有理由相信,知道自己准备做什么、怎么做的科学家不应该因为必须一只眼盯着收银机,一只眼盯着显微镜而分散了注意力。
