Scientific American’s Winter 2015 Special Edition,
entitled “Physics at the Limits,” is a collection of articles by physicists and
physics journalists describing the current status of efforts to solve the
deepest mysteries of the universe. Some of these problems have been worked on
for decades and are no closer to being solved. Ideas that looked promising and
inspired hope years ago haven’t panned
out. I found the overall tone of the issue somewhat downbeat. Nobody is
predicting that success is just around the corner.
