Well now it sits on my shelf, at least one of its earlier incarnations does at least, replete with typos and mistakes, dog-eared, and riddled with curling yellow post-it notes as if slices of factory cheese exploded out from the words I wrote inside. It was not however an albatross, it was a pleasure to put together all the things I thought I knew in one place and see that really I didn’t understand much at all. I still look at it regularly. It’s like a fond family photo, keeping me company through all the long postdoc days.
