The semi-forgotten mathematics of giant shells
"My interest started during a lecture on load-bearing structures. The lecturer showed all these amazing pictures, but did not explain how they were built." Andrew Borgart has been lecturing at TU Delft for 30 years. Alongside this job, he has been pursuing a PhD since 2009 on a half-forgotten intersection between art and science: the mathematical theory of ‘shell structures’, that is, buildings shaped like shells. "They call me innovative, but actually I'm retro."
