Who can dismantle and put back a blast furnace!
I remember walking along Jubilee Park when a man in a bowtie greeted us. He was walking a hysterical-looking poodle. I laughed at the sight. My father reprimanded me, “Don’t get carried away by appearances. That man is a great engineer. He can roll up his sleeves and dismantle and put back a blast furnace.” All his examples were anecdotes or parables; one learnt by example.
That is Shiv Visvanathan remembering his metallurgist father. Take a look!
