How quarks made their entrance into our worldview via cosmic rays and proton accelerators

Sixty years ago Gell-Mann introduced, with a striking sense of caution, a new fundamental layer in the structure of matter. He christened the associated particles 'quarks', a name borrowed from the psychedelic flood of words of James Joyce's novel Finnegans Wake. Independently and simultaneously, Zweig arrived at similar ideas. We outline the circumstances that led to the introduction of quarks.

Comment on 'Ultradense protium p(0) and deuterium D(0) and their relation to ordinary Rydberg matter: a review' 2019 Physica Scripta 94, 075005

The article by Holmlid and Zeiner-Gundersen (2019, Physica Scripta, vol. 94, 075005) contains a number of claims that explicitly or implicitly contradict fundamental knowledge of modern science. Some can only be true if long held conservation laws are broken. One such is baryon number conservation. A second fatal mistake is the treatment of the structure of molecules that disregard fundamental quantum mechanical aspects, such as the concept of kinetic energy operators and the Heisenberg indeterminacy relations.

Comment on 'Phase transition temperatures of 405-725 K in superfluid ultra-dense hydrogen clusters on metal surfaces' [AIP Advances 6, 045111 (2016)]

The article in \cite{HolmlidAIPA2016} has recently come to our attention. It makes a number of extraordinary claims that each contradict well established facts in several fields, ranging from atomic and molecular physics to superconductivity and superfluidity, with practically no supporting evidence. We think it worthwhile to rectify the literature with this comment.
