Is the search for a perfect physics theory a waste of time?
Peter Woit discusses the question at Physics World (May 2017), considering a new book by Frank Close, Theories of Everything: Ideas in Profile: The great success of the Standard Model has left particle physicists in a difficult position; with not just the Higgs, but all other results from the LHC and other particle-physics experiments so far agreeing perfectly with the theory.
