"Emmy: Moldable Physics and Lispy Microworlds" by Sam Ritchie

Over the last few years, The Clojure community has been quietly building out a set of powerful tools for interactive data exploration, mathematical exploration and symbolic computing. Projects like Clerk, Portal, REBL and Reveal are creating a whole new visual grammar and language on top of Clojure.
This talk will discuss my recent work curating and extending this set of tools into a Clojure-y environment that feels like an open-source, interactive, moldable alternative to Mathematica. We'll tour together through examples of documents that weave mathematics, prose and immersive, visually stunning microworlds, all of which are programmable by the end-user.
Thanks to Clojure's simple design and astonishing reach, this system, named the Emmy computer algebra system, is poised to make Clojure a top choice for work in computing and physics education.

29:47 Am I stupid for being completely blown away by this implementation or is the audience for NOT erupting into applause?

One of the most impressive talks I’ve seen in a while. Beautiful implementation
