Digital Art, Lava Lab, Desalination. Feb 1, 2019, Part 1

A series of lines on a wall, drawn by museum staff, from instructions written by an artist. A textile print made from scanning the screen of an Apple IIe computer, printing onto heat transfer material, and ironing the result onto fabric. A Java program that displays its source code—plus the roving attention of the programmer writing that code, and the even speedier attention of the computer as it processes it. All three are works of art currently on display at the Whitney Museum of Art’s ‘Programmed’ exhibition, a retrospective of more than 50 years of art inspired or shaped by coding. Host John Dankosky is joined by Whitney adjunct curator Christiane Paul, plus artists Joan Truckenbrod and W. Bradford Paley, to discuss the past and future of digital art. If you want to make a lava flow from scratch, the ingredients are fairly simple: one big crucible, and 200 to 700 pounds of 1.2 billion-year-old basalt dug from a quarry in Wisconsin. Combine these two, at 2,200 degrees Fahrenheit, and you have The Lava  Project—a scientific study of the flow of molten lava in an upstate New York parking lot. Syracuse University geology professor Jeffrey Karson tells SciFri more. Plus: Desalination is the process that converts saltwater into water that can used for drinking, agriculture, or industrial uses—but desalination produces brine, a salty byproduct that can contain other chemicals. Journalist Tik Root talks about the trade-offs when it comes to desalination in this week's Good Thing, Bad Thing. Finally, Vox staff writer Umair Irfan joins SciFri for a look at the Midwest's Arctic temperatures, and other top science headlines, in this week's News Round-up. Subscribe to this podcast.
