Unlike some other reproductions of classic texts (1) We have not
used OCR(Optical Character Recognition), as this leads to bad
quality books with introduced typos. (2) In books where there are
images such as portraits, maps, sketches etc We have endeavoured to
keep the quality of these images, so they represent accurately the
original artefact. Although occasionally there may be certain
imperfections with these old texts, we feel they deserve to be made
available for future generations to enjoy.

A discourse on time, gravity, and the universe that takes the
reader through the subtleties of time, the origin of the universe,
and physical evolution in Einstein's theory and its extensions. Can
time and causality remain fundamental when the classical ideal of
spacetime becomes a concept of limited applicability in quantum
gravity? A thorough exposition on the canonical framework of
Einstein's theory and its extensions reveals the synergy between
gravitation and the cosmic clock of our expanding universe that
renders time concrete, physical, and comprehensible. In conjunction
with a paradigm shift from four-covariance to just spatial
diffeomorphism invariance, causal time-ordering of the quantum
state of the universe and its evolution in cosmic time become
meaningful. The quantum state of the universe is the embodiment of
our shared past, present, and future. The advocated framework
prompts natural extensions and improvements to Einstein's theory. A
salient feature is the addition of a Cotton-York term to the
physical Hamiltonian. Besides bringing improved ultraviolet
convergence, this radically changes the solution to the initial
data problem and the quantum origin of the universe. It lends
support to the quantum beginning of the universe as an exact
Chern-Simons Hartle-Hawking state that features
Euclidean-Lorentzian instanton tunneling. A signature of this state
is that it manifests, at the lowest order approximation,
scale-invariant two-point correlation function for
transverse-traceless quantum metric fluctuations. This initial
quantum state also implies, at the level of expectation values, a
low-entropy hot smooth Robertson-Walker beginning that is in accord
with Penrose's Weyl Curvature Hypothesis. Consequently, the
gravitational arrow of time of increasing spatial volume and the
thermodynamic second law arrow of time of increasing entropy concur
as our universe expands and ages.

The Awakening, originally titled A Solitary Soul, is a novel by
Kate Chopin, first published in 1899. Set in New Orleans and on the
Louisiana Gulf coast at the end of the 19th century, the plot
centers on Edna Pontellier and her struggle between her
increasingly unorthodox views on femininity and motherhood with the
prevailing social attitudes of the turn-of-the-century American
South.
