Bret Victor is an American interface designer, computer scientist and electrical engineer.[^1] He studied electrical engineering at Caltech, graduating in 1999, and at UC Berkeley, where he took a master's in 2001.[^1] At Alesis he developed the Ion and the Micron.[^1] At Apple, by his own account, he designed the earliest user interface concepts for the iPad.[^2] In 2014 he joined the Communications Design Group as a researcher, working on software to let citizens and scientists model and understand systems.[^1]

His 2011 essay on explorable explanations, built with his JavaScript library Tangle, popularised the term.[^1,2] His November 2015 essay "What can a technologist do about climate change?" has a section on media for understanding situations.[^3] Under the heading "model-driven debate" it takes the 2009 Cash for Clunkers programme, notes that neither side showed the calculations behind its numbers, and rewrites the original newspaper proposal with figures the reader can adjust.[^3]

He led the team that founded Dynamicland, a research lab in Oakland, California.[^1,2] The team also invented Realtalk, the system it runs on.[^2] Dynamicland is meant as a computer that is a place, where people work together in the real world.[^4]

The wiki carries his essay [Explorable Explanations](/communication/explorable-explanations/). [Parable of the Polygons](/communication/parable-of-the-polygons/) names it as an inspiration, and the introduction to the [Communication](/communication/) shelf borrows his term.
