About David Halliday. David Halliday (March 3, 1916 â April 2, 2010) was an American physicist known for his physics textbooks, Physics and Fundamentals of Physics, which he wrote with Robert Resnick. Both textbooks have been in continuous use since 1960 and are available in more than 47 languages.
Currently, physicists describe nature as having 4 fundamental forces: the Electromagnetic force, the Strong nuclear force, the Weak nuclear force, and the Gravitational force. At one point in history, the Electric and Magnetic fields were treated as separate. If you count these two fields as separate and add them to the other 3 traditional force fields -- the Gravitational, Strong, and Weak fields -- then, nature might be described as having a total of 5 fundamental fields in Physics.
