Rutherford, the founder of modern atomic physics, highly praised thinking. Late one night, he happened to find a student still immersed in his own experiment and asked curiously, "What were you doing this morning?" The student replied, "I'm doing an experiment." "What about the afternoon?" "Do experiments." Rutherford frowned and continued to ask, "What about that night?" "I am also doing experiments." Rutherford was furious and snapped at him, "You've been doing experiments all day. What time do you spend thinking? " Diligent students are reprimanded, seemingly wronged, but in fact the master is teaching the true scriptures. Many times, people would rather let the years drown in the seemingly valuable busyness, but they are extremely unwilling to take the time to think, so that their thinking always lingers at a low level and eventually gets nothing.
