  Science, Art, and the Search for Meaning: Exhibition Opening Conversation with Dario Robleto

  Block Museum of Art

  2:00 PM McCormick Auditorium, Norris University Center

  EVENT DETAILSmore info

  For Dario Robleto, the practice of art shares a key aspiration with scientific endeavor: both artists and scientists strive to increase the sensitivity of their observations. In her contribution to The Heart’s Knowledge catalogue, Jennifer Roberts (Professor of the Humanities, Harvard University) writes that “the act of measurement cannot be separated from the search for meaning.” What are the tools that artists and scientists use to observe and measure the unknown? How might we use those tools collaboratively to construct new pathways of human understanding across time and distance? How might shared values of empathy, care, and curiosity guide such pursuits?

  In this opening conversation, Robleto and Roberts will be joined by Lucianne Walkowicz, astronomer and co-founder of the JustSpace Alliance, and Michael Metzger, Pick-Laudati Curator of Media Arts and curator of The Heart’s Knowledge, to reflect on these questions. Join us for a discussion that reaches across boundaries to examine the shared pursuit of greater understanding that binds artists and scientists.

  Drop by The Block early and join the Block Museum Student Associates in the galleries for a look at the exhibition.

  Programs are open to all, on a first-come first-served basis. RSVPs not required, but appreciated.

  Richard Braun: Semi-automated Tear Breakup Detection and Modeling on the Ocular Surface

  McCormick-Engineering Sciences and Applied Mathematics (ESAM)

  11:15 AM M416, Technological Institute

  EVENT DETAILS

  Title: Semi-automated Tear Breakup Detection and Modeling on the Ocular Surface

  Speaker: : Richard Braun, Carl J. Rees Professor, Department of Mathematical Sciences, University of Delaware

  Abstract: The tear film is a thin fluid multilayer left on the eye surface after a blink. A good tear film is essential for health and proper function of the eye. Millions of people have a condition called dry eye disease (DED) that is thought to be closely linked to the tear film. DED inhibits vision and may lead to inflammation and ocular surface damage. However, there is little quantitative data about tear film failure, often called tear break up (TBU). Currently, it is not possible to directly measure important variables such as tear osmolarity (saltiness) within areas of TBU. We present a mostly automatic method that we have developed to extract data from video of the tear film dyed with fluorescein (for visualization). We have extracted data for 15 healthy subjects resulting in 467 instances of TBU. Using parameter identification from fits to appropriate math models, we estimate which mechanisms are most important in each instance and determine critical variables such as osmolarity within regions of TBU. Not only is new data obtained, but far more data, enabling statistical methods to be applied. So far, the methods provide baseline data for TBU in healthy subjects. Future work will produce data from DED subjects.
