![“We must be clear that when it comes to atoms, language can be used only as in poetry. The poet, too, is not nearly so concerned with describing facts as with creating images and establishing mental connections. [About describing atomic models in the language of classical physics:]” quote by Niels Bohr](https://sms4smile.com/quotes/i/412/niels-bohr-4542_analogy_we-must-be-clear-that-when-it-comes-to-a_2898071.png)
![“When asked ... [about] an underlying quantum world, Bohr would answer, 'There is no quantum world. There is only an abstract quantum physical description. It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we can say about Nature.'” quote by Niels Bohr](https://sms4smile.com/quotes/i/f3d/niels-bohr-4542_abstract_when-asked-about-an-underlying-quantum-w_1467547.png)
