Professor of Physics Howard M. Georgi '68, chair of the physics department, began work in the mid-1970s on the SU(5) theory. This theory attempts to bring together and to refine two previous theories on the relationship between three of these four forces--weak force, strong force, and electromagnetic force. The fourth force, gravity, is believed to be a derivation of the weak and strong forces...

Many of these countries are already equipped with Soviet planes, such as the MiG-23, MiG-29 and SU-27, that are "aerodynamically competitive" with the F-15. Being as good as the Soviets' best is not good enough, especially when flying against an enemy that may have its entire air force at its disposal. "When you're a pilot, you don't want equality," says Ben Lambeth...

But when Iraqi MiGs and Su-24s began to cross over as well, Iran's air-defense system went on alert, some of the planes were chased away by Iranian fighters, and two of them, according to British intelligence, were shot down...
