I will begin with some historical background on the spectru m of the cohomology ring and its significance in modular representation th eory. I will then discuss Paul Balmer's approach to Quillen stratification \, facilitated by his notion of the spectrum of a tensor triangulated cate gory. Time permitting\, I will then discuss an application of these method s to the problem of classifying the thick tensor-ideals of the stable cate gory of the mod 2 Steenrod algebra.
