The wandering takes me to writing, and the various new starts and old edits I’d promised myself would be my main focus this year. In fact, not surprisingly, much of my energy has been taken up with the tango and Parkinson’s book and its funding. It’s hard not to become preoccupied with percentages and targets and, whilst I believe that this little book is worth the read, the whole crowd-funding thing is variously nerve-wracking, exposing and generally uncomfortable. I did agonise for some weeks before committing. A friend this morning suggested he felt some of his friends were ‘bruised’ by his appeals for support with a recent project which is at the heart of it I think. I have been overwhelmed sometimes by generosity in recent months, both from friends and strangers. But what matters in the end, of course, are the friendships, which I have to hope will come through the process unscathed; and the writing. By this time I no longer have any clear sense of how good it is. What I am absolutely sure of is that it is in essentially the right place: where the personal encounters the general and art meets science. With my friend Tim to a fascinating exhibition of art-science collaborations by Cambridge-based Spanish researchers just before Christmas. The programme quoted writer and science historian Arthur I. Miller on the emergence of a third culture ‘artsci’ where both nurture each other, boundaries dissolve, the results ‘changing forever the way we perceive the world’.
