Rolf Hut is a hydrological scientist from Delft University of Technology. Or perhaps he's better described as MacGyver scientist, attacking problems from different and interesting angles. One such problem was the infamous 1962 escape from Alcatraz, in which inmates Clarence Anglin, John Anglin, and Frank Morris escaped from Alcatraz Federal Penitentiary, by tucking papier-mâché versions of their heads into their beds, escaping their cells through the ventilation ducts, climbing through an...
