At Wednesday’s ceremony, Gates discussed “the importance of interdisciplinary collaboration in advancing computer science,” according to a statement from Cornell.

Gates also brought a baseball glove to catch errant fly balls from the nearby Hoy baseball field, according to Matthew Hayes, who is live Tweeting the event here.

Hundreds of people appeared to be on hand for the dedication.

President David Skorton also spoke at the event.

Gates said computer science has a role in every problem our world faces, according to the Cornell Information Science department.

He may also be sitting through some classes.

Gates said, “I now pronounce this building dedicated,” according to social media accounts.
