Nic Svenson, an IG-Nobel Prize winner, does the maths of the probability of a blink being captured by a camera. How many times you’ve taken a group-picture and someone appears with the eyes closed?
Here’s the rule of the thumb for calculating the number of photos you have to take of groups (less than 20):
- divide the number of people by 3 (if there’s good light)
- divide the number of people by 2 (if the light is bad)
Who said physicists are not suited for solving daily-problems?
