A picture caption describing the MIT Sport Taekwondo team’s demonstration on page 25 of the April 9 issue misidentified the kicker as a prospective freshman. The kicker was Christopher M. Williams, a current graduate student.

An article on Friday, April 9 and a table on Friday, April 16 about APO’s Institute Screw award gave the wrong candidate for 6.041. He is Professor Vivek K. Goyal, not Vineet Goyal. The table caption also mischaracterized the award itself. The Big Screw is an object awarded to the winner, not the winner himself.
