The article offers information on the enigma of the aerodynamic lift and also discusses why planes stay in air. Topics discussed include what generates the aerodynamic force known as lift; views of John D. Anderson, Junior curator of aerodynamics at the National Air and Space Museum, on issue; and also mentions that the Bernoulli's theorem attempts to explain lift as a consequence of the curved upper surface of an airfoil, the technical name for an airplane wing.

The article discusses potential developments in computer technology in the 150 years following 2013, presenting comments from computer researchers including George Dyson, Ivan Sutherland, and Stewart Brand. Topics include the impact of decision-making on the development of the computer industry, the possible development of small computers that communicate directly with human brains, and the possible construction of computers that are not electronic. The reservations expressed by some computer scientists in regards to making predictions are emphasized.
