This is the third edition of the book ‘Nederland in Ideeën ' (The Netherlands in ideas), in which scientists, entrepreneurs and artists share their most valuable insights. This book is based on the question of Dutch designers Victor & Rolf : "What is the greatest thing you've ever seen ." In 2013 Martijn Manders has already written a contribution for ‘Nederland in Ideeën’ under the title "Our heritage ? My heritage?", insights and innovations that will change our country. In this edition he describes the most beautiful thing he had ever seen during an archaeological research in Sweden, surveying the Ghost Ship at 100 meters depth. ‘This is the best ever’ gives a unique glimpse behind many different screens. It provides inspiration, makes recommendations, and shows why expertise is the source of so much beauty.
