This was a great talk, so interesting !

This story highlights the ever-present tension between the way of "observation" (you can learn a lot by just watching) and "measurement" (which invokes in some sense a perturbation of what is measured)... But, why should one choose? To me as a scientist, there is joy and power in both approaches!

This video (linked in the above blog as well) from Mary Silver is also fascinating
