The following slide show is mostly for fun. It was used in the first author's introduction and welcome to the participants at the Dina Workshop on "Computer Modelling in Weed Science" held at The Royal Veterinary and Agricultural University (KVL), Copenhagen, 29 June and 1 July 1996.

Once upon a time far out in the countryside, bathed in the bright sunshine, in the midst of multiple species of weeds, useful plants, human beings and animals, stood the old Agricultural University.


The students prepared for their exams. The scientists pondered over the huge unsolved problems of life, such as: `How and why do weeds compete with crops? and `What really is the difference between weed and crop?' Then came the computer. And here we see all the scientists at their monitors, all hoping to extort the true formula of life from the computer. The life of the intrinsic soul of a true weed.


But let us see what he might find if he used Compter Modelling in Weed Science correctly . The open question is: `Would he find anything he did not see already if he had been looking closely enough?' Of course he may very well continue to look and so he does. Therefore we have more and more scientists, and fewer and fewer of them are looking at the real weeds.


Good luck with computer modelling.

I really do hope you will find the secret of weeds.


The first time this slide show was used was in front of a live audience as part of the main scientific presentation at the anniversary of The Royal Veterinary and Agricultural University on 8 March 1993.
