John Rauser's Strata 2014 keynote argues that programmers can learn statistics quickly by simulating random processes and shuffling data. He explains p-values through resampling rather than formulas.

Bret Victor's talk proposing a new kind of maker space built for seeing and understanding a project's behavior: inside it, across time and across possibilities. It argues for scientific understanding over recipes and rules of thumb.

Scott Galloway's TED talk uses data to argue that young Americans are financially worse off than earlier generations, calling it a great intergenerational theft. He covers root causes and what could change it.

Writer and artist James Bridle shows how strange and disturbing children's videos on YouTube, from surprise eggs to algorithmic mashups, are produced for ad revenue. He argues they reveal problems in a data-driven internet.

Berkeley neuroscientist Jack Gallant shows how fMRI brain mapping can be used to decode what a person sees, with visualizations of brain activity and its implications.
