Synthetic material

German scientist ehrlich tried to kill trypanosoma with dye, but failed many times. Once, he learned from a chemical magazine that the chemical "Atoscher" can kill trypanosomes, but it will make people blind. He wanted to change the chemical structure of the drug to reduce its toxicity, and he did experiments again and again. After 605 failures, he finally succeeded in producing 606 (arsenic vanadium amine), saving the lives of countless coma patients and syphilis patients.

If ehrlich, a scientist, took a shortcut directly, he would use the chemical "Atoscher" to treat the sleeping patients and syphilis patients. Then although these patients are not life-threatening, they may be blind. For ehrlich, this practice failed to fulfill the duty of a doctor-to help patients alleviate their pain. So he thought: Is there a better way to cure this disease without making the patient blind? So he kept detouring, trying to find a better way. In the end, he succeeded, and countless patients got good treatment. When the shortcut doesn't work, please take a detour. Maybe success is not far away.
