I guess I didn’t get your humor.
Too many years in the industry.
Hard to believe things that massive are that
delicate.
Almost went to work at UofA on spin casting. Ended up in oceanographic research instead.
With my "Windex" joke, I was referencing that classic Hugo Award-winning science-fiction story "The Star," by Arthur C. Clarke, published in 1955. It contains a mention of a cleaning lady at an astronomical observatory mistakenly using Windex on the sensitive mirror of a telescope.
Sorry, thought that you, as an astronomer (or rather someone who worked at an observatory) would have caught that.
