In the News & Comment article "Super Collider advocates tangle with cost cutters" by Mark Crawford (12 Jan., p. 152), the collision energy of the Superconducting Super Collider (SSC) was incorrectly described as being two orders of magnitude greater than that of the Tevatron. The SSC's collision energy is supposed to be 40 trillion election volts—20 times that of the Tevatron. In addition, the $7.2-billion cost estimate for the project is based on inflated dollars, not constant dollars, as was stated.
