The mission of the publication "Delft Science in Design 2" is to promote and advance the exchange of lessons learned on design between university and industry. Also, it aims to amplify the visibility of the results of academic effort in design at Delft University. The questions 'What is design?', 'What is engineering?', 'What is science?' can be fiercely debated. Between the extremes of artistic design and pure science, the transitions are like in fluid: they are smooth and gradual. An approach focusing on how the university deals with knowledge may provide a better entry to the debate. The mutual understanding between scientists from different disciplines may get lost. It is one of the two major objectives of the Delft Science in Design congress to offer a kaleidoscope of the activities of the various faculties to all university colleagues and students, so that staff and students can be made aware of activities in other laboratories, and have the opportunity to be informed on details. Being informed is the first step to understanding.
