"A quantum system cannot be
'turtles all the way down'."
- J.Cramer

"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
