Teachers were so convincing, though.
Physicist and Nobel laureate Niels Bohr (7 October 1885 – 18 November 1962) developed our understanding of the atom. The following quote has been attributed to him (perhaps falsely). Nonetheless, it is a compelling passage.
Bohr thought that the fundamental world—particularly, the quantum one—doesn’t really exist in the way we describe it. Through language, we merely suspend our elementary concepts above it.
But then again, argue many scientific realists, it would be miraculous if our scientific theories were not at least approximately true descriptions of the physical world.
