I always thought the webcast announcers for the Brooks PR webcast were a little nerdy, but when they dropped the term Tesseract during the girls 2 mile I have no doubt that they are true blue nerds. This might be the nerdiest thing ever said during a race. Good thing it was said during the 2 mile it would have gone over everyone else's head.
Tesseract - the representation of a cube in the fourth dimension.
Tesseract - the way the three witches in the young adults book "A Wrinkle in Time" travel through space and time.
