THUNK – 98. Mixed Reality & “Game” Design

Maybe VR isn’t a specific thing, but part of a continuum of physical/virtual experience called “mixed reality.” Regardless of how you think about it, the virtual already plays a significant role in your life, & game designers (as terrible a name as that is) are the ones building your future.

THUNK – 93. Mathematics: Discovered or Invented?

Is mathematics discovered or invented? Is it the language which encodes the cosmos, or an imaginary human tool? Does mathematics, in its pure abstraction, tap the inherent nature of the universe…or is it just our imagination? In the longest THUNK video yet, we dive into the metaphysics of mathematics, & the seemingly unanswerable questions therein.
