HistoGrafica is a community-driven website with high aims - making a large amount of historical pictures easily accessible in one place on the web. Everyone can share and describe their old pictures on HistoGrafica and help expand this free archive. Together, we can create the biggest, freely available archive of geo- and timetagged historical pictures in the world.
This archive is designed as a resource for enriching your math courses and nurturing your interest and talent in mathematics! Each Math Fun Fact is a math puzzle or short article that contains a cool mathematics idea. You'll can learn about the mathematics of things like card shuffling to poker to computer vision to fractals to music, just to name a few. This makes great enrichment material for gifted math students or problem-solving groups.
