Here you'll find a summary of Asimov's Three Laws of Robotics, plus
the additional Law. For more info, please click the link (below) to
the Wikipedia article on the Laws of Robotics, which is quite
thorough.
"In science fiction, the Three Laws of Robotics are a set of three
laws written by Isaac Asimov, which most robots appearing in his
fiction have to obey. First introduced in his short story 'Runaround'
(1942), they state the following:
1. A robot may not harm a human being, or, through inaction, allow a
human being to come to harm.
2. A robot must obey the orders given to it by human beings, except
where such orders would conflict with the First Law.
3. A robot must protect its own existence, as long as such protection
does not conflict with the First or Second Law."
The additional Law, rather than being the Fourth Law, was rather
whimsically called the 'Zero-th' Law, since its scope is considered to
be greater than that of the higher-numbered laws:
"Asimov once added a 'Zeroth Law', so named to continue the pattern of
lower-numbered laws superseding in importance the higher-numbered
laws. The character R. Daneel Olivaw is the first to give the Law a
name, in the novel Robots and Empire; however, Susan Calvin
articulates the concept in the short story 'The Evitable Conflict'. In
Robots and Empire, R. Giskard Reventlov was the first robot to act
according to the Zeroth Law, although it proved destructive to his
positronic brain, as he was not certain as to whether his choice would
turn out to be for the ultimate good of humanity or not. R. Daneel,
over the course of many thousand years, was able to adapt himself to
be able to fully obey the Zeroth Law. As Daneel formulated it, the
Zeroth Law reads
0. A robot may not injure humanity, or, through inaction, allow
humanity to come to harm.
A condition stating that the Zeroth Law must not be broken was added
to the original Laws."

I believe you will find answers to your physics questions
(Schrödinger's cat, the Heisenberg uncertainty principle, and quantum
leaps) in "Asimov's New Guide to Science." This is a wonderful book.
Asimov was a master at tackling complex topics and making them
intelligible to the layman.
