Back to FAQ for FQXi

What does FQXi stand for? (What's the deal with the X?)

The F, Q, and I in our acronym FQXi come from the first letters in "Foundational Questions Institute." The X symbol stands in for "Physics and Cosmology," our focus. The X symbol is also widely used in science to represent the "unknown quantity"—since an FQXi specialty is investigating unknown quantities.
