Statement on Racial Injustice

The American Institute of Mathematics and the Math Teachers’ Circle Network stand in solidarity with the Black community and with peaceful protesters across the nation and the world in outrage, grief, and despair over the brutal police killing of George Floyd and many other Black individuals before him.
