Review of ChildArt Magazine: Arts and Mind – The Brain Science of Human Experience, Guest Editor, Susan Magsamen; Editor, Ashfaq Ishaq.

I sat down to read this ChildArt issue about art and the brain a few days after I learned of Marian Diamond’s (1926-2017) death . Perhaps best known for her studies of Einstein’s brain, which noted that he had more support cells in the brain than average, she was also a distinguished educator and a pioneer in brain plasticity research. The two products of her legacy that influenced me directly came to mind as I absorbed the essays. First, I recalled how Diamond’s skill as an educator came through in an interactive videotaped lesson on the brain she did during her tenure as Director of the Lawrence Hall of Science (recorded in 1990). While explaining the brain’s functions and dissecting an actual brain she also sensitively responded to questions posed by a group of two elementary school students and two graduate students. The composite demonstrated how a talented instructor is able to stimulate learning . In addition, and similarly, when I was a docent at the Hall, one of the most popular installations was an interactive installation about the brain, designed by Diamond, that engaged visitors of all ages and backgrounds.
ChildArt’s “Your Brain on Art” likewise captures the importance of engagement in education and human development, introducing projects that highlight children in schools as well as cross-cultural and community outreach. Divided into three sections, the issue also reminds us that children learn and experience life in more than one way.

Review of A Mind at Play: How Claude Shannon Invented the Information Age by Jimmy Soni and Rob Goodman

As a fan of biographies, I was excited to learn about A Mind at Play: How Claude Shannon Invented the Information Age. Not only is it a timely biography, this well researched and easy to read book also captures the imagination. Because Jimmy Soni and Rob Goodman take care to situate Shannon’s contributions in their cultural context the volume encourages the reader to explore their broader implications. Claude Shannon’s legacy is no doubt of particular interest to Leonardo readers due to the range of his work. If Shannon’s training and conception of Information Theory brings the current elevation of STEM disciplines (Science, Technology, Engineering, and Math) to mind, many of his lesser known projects clearly align with projects associated with the STE(A)M (the inclusion of Art) community, although the authors never speak of STEAM per se. These include the playful spirit evident in his ongoing tinkering with electronic toys, his multi-faceted studies of juggling, and his unicycle experiments.
So, who was Claude Shannon? Born in 1916 in Michigan, by all accounts Shannon had an ordinary childhood. Noteworthy traits included a love of math and science, a dislike of facts, and mechanical inclinations. These proclivities led him to purse a dual degree in mathematics and engineering at the University of Michigan. After Michigan, Shannon was hired by the well-connected Vannevar Bush, then at MIT and later founder of the National Science Foundation (NSF), to help with his differential analyzer. This was a mechanical analog computer that depended on combinations of equivalent equations, using a wheel-and-disc mechanism for computation. A major problem was that the equations needed to be reconstructed for every problem, in effect annihilating the very efficiency the machine was intending to add to problem solving. The resounding question was how could it reassemble itself on the fly? Shannon, who was conversant with both symbolic logic and electrical circuitry, produced a landmark master’s thesis with an innovative solution. Titled “A Symbolic Analysis of Relay and Switching Circuits,” the young Shannon tied Boolean logic and circuitry together, conceptualizing a path where 1’s and 0’s could represent logical operators of Boole’s (AND, OR, NOT) system, with an on switch standing for “true” and an off switch for “false.”
After a brief stint at the Institute for Advanced Study (Princeton, New Jersey) Shannon joined Bell Labs to work on World War II projects. Here he found an environment that fostered cutting-edge discovery and even met a visiting Alan Turing, another key figure of the Information Age. The sections discussing the shared interests of Shannon and Turing are among the book’s high points, particularly in light of the role of computers in contemporary life. Both probed machine intelligence, feedback and programming commands, and cryptology. The authors tell us that, according to Shannon, much was also left unsaid between them. He did discuss his notions about Information Theory with Turing, but they needed to avoid cryptography because of security concerns.
