A chemistry-profession fraternity founded at the University of Wisconsin, Madison. Many Nobel Laurates and other famous scientists have been bred from this fraternity, including Linus Pauling, and Glen Seaborg.

Contrary to those who claim Alpha Chi Sigma is wanna-be frat, it truly is a frat, albeit a more academic driven one. It was made coeducational in 1969. This hotly debated topic was unanimously agreed upon after the University of Michigan swim team walked through the halls during the break. Female members are called "brothers"

Chapters of Axe can range from notoriously hard partying (alpha chapter), to very academic, to a mix of the two. Their colors are Chrome Yellow and Prussian Blue, and the flower is the red carnation.

Actives often refer to themselves as AXE (if no chapters of Alpha Chi Epsilon are present), but nationals does not appreciate this
"You're in a frat? You're a girl!"
"Alpha Chi Sigma is coed, and since I'm a chemist, its a good idea."
