Knocking on Heaven’s Door: How Physics and Scientific Thinking Illuminate the Universe and Modern World

Lisa Randall’s Knocking on Heaven’s Door: How Physics and Scientific Thinking Illuminate the Universe and Modern World, is written in understandable terms, and accomplishes the goal of answering that question.

Randall’s exposition deals with many modern concepts of physics and introduces them to the reader with ease.  A preliminary background in science is given with a discussion of Galileo, his concepts, and theories.  A brief history and discussion on molecules as well as atomic theory is given, up to the present day, leading to a discussion in modern science and physics, specifically the LHC, short for Large Hadron Collider. The LHC is discussed in great length along with its hope to discover information on the origin of mass.  Conflicting concepts of science versus religion are also briefly touched upon as well.

Randall’s book not only discusses several difficult scientific concepts, but she skillfully conveys scientific information in a way in which the general reader can understand.  It is well-written, and gives the reader a lot of information not only about science, but the scientist also.

There are several illustrations, which make for a useful tool to further explain some scientific concepts.  Randall proves her writing skill in aiming this book for the general reader without losing the complexity of the concepts she discusses.  Randall tackles some of the misconceptions associated with some theories in present day physics.  However, Randall’s adept knowledge combined with her writing, allows the reader to glean into the future so as to see the potential in the field of science, in particular physics, and makes for an enlightening and exciting read.
