[49]In British universities, the chancellor is the representative head, and the vice-chancellor is the one who holds the actual political power and is in effect head of the executive, to whom everybody else reports.

Sept. 1925 in Muenchen” [IL-JeCZA, L12/83/1/1]). The second version is extant in a draft in English and as a fragment in Hebrew (see “Draft. Minutes of the second Meeting of the Board of Governors of the Hebrew University Held at Munich in the house of Dr. Eli Strauss September 23rd and 24th, 1925” [OCAJA, Felix M. Warburg Papers, MS-457, box 220, folder 6], and “Minutes of the Second Meeting of the Board of Governors of the Hebrew University held in Munich at the home of Dr. Eli Straus, 23 and 24 September 1925” (in Hebrew) [IL-JeHUCA]). The editors of Freundlich 1977 claimed that the first version of the minutes had “not been traced” (see Freundlich 1977, p. 419).

[54]Decades later, philosophers began to discuss the question of whether one should deduce and embrace ontological consequences from the fact that the wave function is defined on configuration space rather than on spacetime. Those who answer this question affirmatively often call themselves “wave function realists.” For sources see Ney and Albert 2013. [55]For the distinction between different kinds of hidden variable theories, see Barrett, J. 1999 for detailed analysis of Einstein’s manuscript (Doc. 516), see Belousek 1997 and Holland 2005. Belousek and Holland disagree on what the hidden variables in Einstein’s theory are: Belousek argues that it is the principal directions that Einstein introduces, whereas Holland argues that these are func- tions of and thus not hidden variables. Instead, he takes the positions of the particles as the hidden variables of the theory. [56]Dannen 1997. For their relationship, see Lanouette 1992, ch. 6.
