"A quantum system cannot be
'turtles all the way down'."
"It is better to think of parts
of the universe as splitting.
As Everett once said (roughly),
if a mouse observes the universe,
the mouse, not the universe, is changed.
I would say, if a human mind
observes the universe, the mind,
not the universe, is split."
- Frank J. Tipler
"In the early 1950s, my mentor Fritz Bopp
pondered the question as to why the probabilities
in quantum mechanics appear as absolute squares
of complex amplitudes. This led to a series
of papers with titles such as "Dice Games Whose
Tokens Move Quantum Mechanically".
In 1953, I had the great chance to spend a year
in Copenhagen. One day Niels Bohr came to me saying:
"I received again a manuscript by Professor Bopp.
I do not understand why people occupy themselves
with questions which have been clarified for decades
while there are so many unsolved interesting
new problems around." My imprudent answer:
"Maybe things are not so clear", prompted
a series of discussions."
- Rudolf Haag
