...in physics the only observations we must consider are position
observations, if only the positions of instrument pointers. It is a great
merit of the de Broglie-Bohm picture to force us to consider this fact. If
you make axioms, rather than definitions and theorems, about
the "measurement" of anything else, then you commit redundancy and risk
inconsistency. -- J. S. Bell

Fortune Quote #3443
It would seem that the theory [quantum mechanics] is exclusively concerned
about "results of measurement", and has nothing to say about anything
else. What exactly qualifies some physical systems to play the role
of "measurer"? Was the wavefunction of the world waiting to jump for
thousands of millions of years until a single-celled living creature
appeared? Or did it have to wait a little longer, for some better
qualified system ... with a Ph.D.? -- J. S. Bell

Fortune Quote #3441
I know that most men, including those at ease with problems of the highest
complexity, can seldom accept even the simplest and most obvious truth if
it be such as would oblige them to admit the falsity of conclusions which
they have delighted in explaining to colleagues, which they have proudly
taught to others, and which they have woven, thread by thread, into the
fabric of their lives. -- Tolstoy

I protest against the use of infinite magnitude as something accomplished,
which is never permissible in mathematics. Infinity is merely a figure of
speech, the true meaning being a limit. -- Carl Friedrich Gauss
