I read this article by Hawking which includes this quote "
In classical mechanics one can
predict the results of measuring both the
position and the velocity of a particle.
In quantum mechanics the uncertainty
principle says that only one of these
measurements can be predicted; the ob
server can...
I am unclear about this law of the conservation of baryons; does it mean that the number of leptons can change OR the number of baryons but not both? Also, does it mean that no experimental evidence shows that baryons can decay into mesons. Can someone state clearly the law of conservation of...
A book I read says that when virtual particle-antiparticle pairs are created near a black hole then sometimes one of the particle pairs will be captured by the black hole while the other one will be freed to move away as a real particle - then this causes the black hole to lose mass and thus...
I read this book called How To Teach Relativity to Your Dog by Chad Orzel. In the book he discusses how an electron is known to have mass but is also considered a point like particle.
He said that some interpretations consider the electron thus to have an infinitely dense mass which should...
