Letter to the editor

Our platform is open to well-written and well-argued letters to the editor, written by TU Delft students and staff.

The maximum number of words is 700.

A letter to the editor can be written in response to something happening at TU Delft or as a reaction to an article.

In the latter case, this is possible if there are inaccurate information or conclusions. In that case, one reaction is posted, because in principle, letters to the editor are not used to discuss a particular topic.

The editors also reserve the right to reject letters submitted if, in their opinion, they do not contain any new arguments.

If a letter is refused, the editors will explain this to the submitter once. No further correspondence will take place about it.

The editors reserve the right to edit letters to the editor, to shorten them and to ask for additional arguments. This is done in consultation.
