In 1957 I tried to get my grandma to marvel at the travelling star-like Sputnik 1. All she said that night in our Strathfield backyard was: "It's not right. It's not right." Over a generation later, in 1992, in Perth, after a wondrous dinner cooked by my wife, I lovingly carried my oldest grandchild on my shoulders towards her mum's car and in the dark sky above was a wondrous full moon. I said, "You know Steffie, Grandpa has five experiments way up there on Old Man Moon". Steffie warmed my ears and said "That's nice Grandpa" before sliding off to play with my wife's cat.
