248 “We cannot assume that our knowledge of physical principles is yet complete”: Hubble (1937), p. 26.
248 “a desire to show that the red shift was not an expansion”: AIP, interview with C. Donald Shane by Helen Wright on July 11, 1967.
248 Perusing Hubble's writings on the idea of an expanding universe: All quoted phrases in this paragraph are from Hubble (1937), pp. v and 26.
249 “around the earth in a second, out to the moon in 10 seconds”: Ibid., pp. 29–30.
249 “represent either actual recession (expanding universe) or some hitherto unknown principle of nature”: HUB, Box 15, Hubble to Harvey Zinszer, July 21, 1950.
249 “I just don't understand this eagerness”: Douglas (1957), p. 113.
16. Started Off with a Bang
250 “Would it not be more practical to have the herr professor come here”: “Einsteins Start Trip to America” (1930), p. 5.
250 to hunt for the sole twelve men in the world: “Relativity” (1930), p. A4.
250 “This reminds me of a Punch and Judy show”: “Einstein Battles ‘Wolves’” (1930), p. 1.
250 “his face … as smooth as a girl's”: Ibid., p. 2.
250 Arthur Fleming … first extended the invitation: Sutton (1930), p. A1.
251 steady round of private engagements: “Einstein's Date Book Crammed” (1931), p. A1; “Notables of World to Opening” (1931), p. B14; Feigl (1931).
251 Einstein laughed like a little boy: Hall (1931), p. 28.
251 “They cheer me because they all understand me”: Isaacson (2007), p. 374.
251 “Your husband's work is beautiful”: HUB, Box 8, “Biographical Memoir.”
251 Einstein had been given a room at Mount Wilson's main offices … issuing keys: AIP, interview of Nicholas U. Mayall by Norriss S. Hetherington on June 3, 1976.
252 “I have kept completely out of the Einstein excitement”: HP, Hale to Harry Manley Godwin, January 15, 1931.
252 carefully orchestrated expedition was arranged for Einstein: HL, Walter Adams Papers, Supplement Box 4, Folder 4.87.
253 young filmmaker named Frank Capra: In 1918 Capra had graduated from Throop Institute, later renamed the California Institute of Technology, with a BS degree in chemical engineering.
253 “And here he comes … down from the sun tower”: CA, Einstein Film Footage, 1931.
253 “This hundred-inch reflector was completed about thirteen years ago”: Ibid.
254 “Well, my husband does that on the back of an old envelope”: Clark (1971), p. 434.
254 After an early dinner the party returned to the 100-inch telescope: HL, Walter Adams Papers, Supplement Box 4, Folder 4.87.
254 on that day he at last conceded: “Einstein Drops Idea of ‘Closed’ Universe” (1931), p. 1.
254 “A gasp of astonishment swept through the library”: Christianson (1995), p. 210.
254 “the red shift of distant nebulae has smashed my old construction like a hammer blow”: “Red Shift of Nebulae a Puzzle, Says Einstein” (1931), p. 15.
254 “biggest blunder”: This is not a direct quote from Einstein. The Russian-American physicist George Gamow relayed this story in his autobiography, saying Einstein used the now-famous phrase while they were having a chat one day. Gamow (1970), p. 44. Ironically, at the start of the twenty-first century, astrophysicists reinserted the constant into their cosmological calculations to help them explain why the universe's expansion seems to be accelerating as the eons pass.
256 “made Einstein change his mind”: “Hubble to Visit Oxford” (1934).
256 “It remains to find the cause”: Lemaître (1931a), p. 489.
256 “beginning of time” … “philosophically, the notion of a beginning of the present order of Nature is repugnant to me”: Eddington (1931), pp. 449–50.
256 “not believe that the present order of things started off with a bang”: Eddington made this remark in a series of lectures given at the University of Edinburgh, later published as Eddington (1928). See p. 85.
256 Hoyle using a similar description: Hoyle's radio lectures on the cosmos, in which he first used the term Big Bang, were later published. See Hoyle (1950), pp.
