scientific background. Tyson transforms everyday experiences into venues of cosmic enlightenment as he probes the philosophy, methods, and discoveries of science, including stellar evolution, the conservation of energy, the electromagnetic spectrum, gravity and thermodynamics. Deftly demystifying astronomical terms and concepts such as the Big Bang, black holes, redshifts, syzygy, and Kirkwood Gaps, Universe Down to Earth traces the life of the stars from birth to death; presents the Periodic Table of Elements, highlighting noteworthy elements such as titanium, iron, and hydrogen; gives an unorthodox yet entertaining tour of famous constellations; and tackles modern-day astrology. (Carl Sagan)
