The Octonions
John C. Baez
Bulletin of the AMS, April 2002, pp. 145-205
There are only four normed divisions algebras: the real numbers, the complex numbers, the quaternions, and the octonions. The latter bridge many areas of mathematics, such as Clifford algebras and spinors, Bott periodicity, projective and Lorentzian geometry, Jordan algebras, and exceptional Lie groups. The also appear in theoretical physics in connectin with quantum logic, special relativity, and supersymmetry.

Recent Developments in the Cohomology of Finite Groups
Alejandro Adem
Notices of the AMS, August 1997, pp. 806-812
Cohomology of finite groups can be described completely algebraically, but it can also be described in topological terms. It forms an important bridge between algebra and topology and touches a number of areas of mathematics. There are now a number of ways to compute group cohomology.

An Introduction to Computational Group Theory
Ákos Seress
Notices of the AMS, June/July 1997, pp. 671-679
Computational group theory is one of the oldest and most developed branches of computational algebra. Different techniques and problems are associated with specific types, of groups, such as finitely presented groups, polycyclic groups, permutation groups, and matrix groups.

On Finite Simple Groups and Their Classification
Ron Solomon
Notices of the AMS, February 1995, pp. 231-239
Although the classification theorem for finite simple groups was felt to be complete in 1983, and in spite of about 15,000 pages devoted to the proof, not all details had been published, and loose ends remained. Since then, efforts have continued to clean up the classification and address new problems that it suggested. Interesting questions remain, especially with respect to the sporadic simple groups, and the "Monster" in particular.
