“…Furthermore we often come across helicoidal structures and objects that are related to navigation in nature, science and engineering. For instance; creeper plants, helicoidal staircases, helicoidal conveyors, parking garage ramps, helicoidal railways, moving walkways and footbridges, helicoidal towers and (nowadays) skyscrapers (Capanna et al, 2012), helicoidal fractures in geology (Pollard and Fletcher, 2005), helicoidal paths, tropical cyclones (Levina and Montgomery, 2010), electronic states on the helicoidal surfaces (Jensen, 2009) and helical channels (Morales and Rosa, 2007).…”
