If anyone is curious about the science behind Bobby’s Socks, I think the article linked from McGill University might be a worthy read. From Bobby’s Socks, the strands of yarn to create the socks was the metaphor for DNA. The picture of the helical strand triggered me to title the novel, Bobby’s Socks.
If we carry the idea further, each pair of socks are different as in each human beings genetic code is slightly different from another. And that is why the title is in the possessive, as in, those are Bobby’s. But those socks could easily be, Hanna’s Socks, Rebecca’s Socks, or your socks.
Of course, the highlighted scientists within the article are the real hero’s that have spent decades of their lives seeking answers to complex questions. I don’t think it’s to far afield to express that their work saves lives.
