nass news 2019 may Mobius Infinity"Infinity Possibility" was dedicated this week [May 5th, 2019] at Brown University in Providence R.I. thanks to a grand design challenge to the university's School of Engineering by 1979 alum Charlie Giancarlo. Giancarlo wanted something "that would represent the rigor of engineering work, but have artistic beauty as well". According to Brown news, "A student group called Brown STEAM (Science Technology Engineering Arts and Mathematics) took up the challengte, and the result of more than two years work is a stainless steel noon mark sundial measuring 15 feet long and 4 feet high. STEAM’s then-president tapped Austin and David Schurman, both first year students at the time, as project managers. The pair assembled a team of around 20 students to start brainstorming ideas and getting input from the broader Brown community.

David Shurman and his team worked with a sundial expert, Bill Gottesman, a member of the North American Sundial Socity,  Shurman said, "We wanted to explore the interplay of the mobius strip's shape with that of Brown's unique analemma path to make a sculpture personalized to the location it will inhabit for, hopefully, up to a century." In the end section of the "lazy eight" mobius strip is a hole allowing the noonday sun to fall on the northward piece of the strip below. The lower mobius band has an etched analemma showing civil noon in front of Brown's Engineering Research Center.
