Advent Day 19
There were two men trying to decide what to do for a living. They went to see a counselor, and he decided that they had good problem solving skills.
He tried a test to narrow the area of specialty. He put each man in a room with a stove, a bucket of water, and an empty pot on the stove. He said "Boil some water in the pot." Both men filled the pot with water from the bucket and turned on the burner to boil the water. Next, he put them into a room with a stove, a bucket of water, and a pot full of water on the stove. Again, he said "Boil the water in the pot." The first man immediately turned on the burner. The counselor told him to be an Engineer. The second man emptied the pot and proudly said that now the problem is reduced to the previously solved problem. The counselor told him to be a mathematician.
