Nuclear Reaction at Intermediate to Relativistic Energies: what data tell us (I)
Jeg kender ikke meget til meget;det jeg kender til er i forvejen meget udbredt.Tœnk at vide bare een bestemt ting,for eksempel forholdet mellem mariehønens pletter.
Benny Andersen,Viden1965
I do not know much about anything;what I know is already commonplace.Wouldn’t it be nice to know just one fact,for example the proportions of the spots of the ladybird.

To view the world in this wayIs to see it with the eyes of a gambler.Our best choice is to cast the die again and again.To let it keep rolling in the hopeThat it will give returns high enoughto inspire new expectations.
Att betrakta världen så är att se på den med tärningsögon.Vårt bästa val är att kasta tärningen ofta, ofta.Att ständigt låta den rulla, att den må falla utmed en kvot stor nogför en ny förväntan att andas. Harry Martinson
Tärningspelet, 1971
