Comments on "100 Years of Quantum Mysteries"
To the February 2001 issue of Scientific American, Max Tegmark and John Archibald Wheeler contributed an article titled "100 Years of Quantum Mysteries", giving an overview on the foundations of quantum mechanics. (This article is also available on the arXiv as "100 Years of the Quantum".) This comment points out several flaws in their article.

Einstein about orthodox quantum mechanics and "hidden" variables (in German)
A long quotation taken out of the 1955 volume edited by Schilpp. Einstein himself explains carefully his position. A few introductory remarks by Roderich Tumulka.
Comment on "Improving Students' Understanding of Quantum Mechanics"
Travis Norsen comments on the article "Improving Students' Understanding of Quantum Mechanics" by C. Singh, M. Belloni, and W. Christian (PHYSICS TODAY, August 2006, page 43). (Scroll down to the second comment.)
Klein-Gordon wave functions guiding particles
A first proposal for what may be the guiding equation appropriate for Klein-Gordon wave functions was made by de Broglie. Dissatisfied with this proposal for various reasons, Horton and Dewdney proposed an alternative law of motion; it can be found, e.g., in a paper by Horton, Dewdney, and Nesteruk. In a comment on that paper, Tumulka pointed out that this law of motion is often ill-defined. Horton and Dewdney have written a reply to that comment, and Tumulka a response.
