Tonight at 9 p.m., WTTW Channel 11 will broadcast the PBS science and technology show “Making Stuff: Faster,” hosted by David Pogue, The New York Times‘ technology correspondent. The show will include a segment on the speed of airline boarding. Pogue will conduct an experiment with real people and a real airliner to test two algorithms. One of them was developed by former Fermilab postdoc Jason Steffen. He is now a fellow at Northwestern University.
