To improve is to change, so to be perfect is to have changed often.
— Winston Churchill 
Physics is by definition the study of change. Alas! We are also burdened with the frailties that all humans are often burdened with, namely a resistance to change. But change we must for how can we not practice what we study and have learned; for without change there is no advancement in our understanding and personal development.
The QLM summer school 2015 is organised in that spirit, namely with a desire for change. We have felt a great need for accompanying curriculum for Quantum, Light & Matter members to better aid us in solving and tackling the problems we face as students of physics: to broaden our minds, to deepen our thinking and to observe the larger picture upon which we may start to build a satisfying career in academia and/or industry.
With this said we welcome and encourage you all to take part non-passively in your QLM summer school 2015 – designed by PhD students for PhD students.
