The scientists appear in the Gallery in reverse alphabetical order (we mean, people called Z first and people called A last). This is because research has shown that people whose names begin with letters near the start of the alphabet tend to be more successful in life (http://www.quirkology.com/UK/Experiment_surname.shtml). Maybe because they are always first in lists!
Here at I’m a Scientist we think life should be more fair, and we try to do our bit to make it fairer. So we are putting the people from the end of the alphabet first for once.
