Describe why some stars, such as white dwarfs and neutron stars
become degenerate. What are the two fundamental physics principles
that underpin the concept of degeneracy?
Given that virtually nothing can escape from black
holes, explain how black holes are important in producing the
enormous luminosities observed from the centers of some
galaxies.

problem:
A system comprises three distinguishable marbles (red, white,
and blue) each of mass m which may be found on any step of a
staircase whose steps are a distance h apart, the energy is not
specified but the temperature is.
(a) What kind of ensemble is this?
(b) What temperature T of a heat bath will maximize the
probability of finding all three marbles on the first step above
ground level?
(c) What is this...
An amateur astronomer is researching statistical properties of
known stars using a variety of databases. They collect the color
index, or B−V index, and distance (in light years) from Earth for
30 stars. The color index of a star is the difference in the light
absorption measured from the star using two different light filters
(a B and a V filter). This then allows the scientist to know the
star's temperature and a negative value means a hot blue star....
