Apple CEO Tim Cook is a full-on geek when it comes to augmented reality.

Cook has raved about AR’s potential in a number of interviews the last year, but according to a PhD student at the University of Oxford, Tim actually has a great understanding of the technology. In a story shared on Reddit, the student reveals how Tim Cook dug deep into the details of the tech during a recent demo.

One of the world’s oldest universities has given Apple’s VP of Design, Jony Ive, another honorary PhD to add to his growing collection.

Not to be out done by their centuries old rivals at Cambridge, the University of Oxford conferred an honorary Doctor of Science degree to Sir Jony at a ceremony on June 22, giving him two degrees from two of the world’s oldest and most prestigious universities.
