There are real costs that someone must pay. A promising approach adopted by some physics journals is to have the authors pay, with readers having free access. NSF considers author publication fees a reasonable part of doing business, and physicists are including these costs in grant proposals. In

I'm amused/bemused by the history of the word atom, from the Greek meaning not (a-) cuttable (tom, as in tomography). The 19th-century scientists who used the word knew Greek, so for them the word itself was presumably perceived as two components, a-tom, but the object itself was deemed
