Whatever Albert Einstein might think of Princeton’s carnival-style birthday embrace of him, how could he resist this scene? Mayor Liz Lempert (on left) is obviously enjoying the moment, too, as Co-Founder of Pi Day Mimi Omiecinski of the Princeton Tour Company hands a $314.15 check to the winner of the Einstein Look-a-Like contest, 19 month old Lusia Bonner, who also won a bike from Kopp’s Cycle Shop that she may have to save for later. Other contestants are in the background. (Photo by Emily Reeves)
