Newton's apple tree

One of the big tourist attractions in Cambridge is Newton's apple tree, outside Trinity College, representing how Isaac saw the fruit fall to the ground and worked out that it must have been gravity's fault. Actually, it's not the real tree, it's a clone/graft from the original (and there's another one in the city's Botanic Garden). 

I'm not sure if tourists have always posed with an apple for the obligatory photo, but loads of them do these days. The apple is always very shiny as well. Good for Instagram I guess :)
