LSS 75: Quantum Computing and Computing in Operations Research

In this show Liz Mahood interviews Dr. Peter McMahon, Cornell Assistant Professor of Applied and Engineering Physics.  He walks us through quantum computers and what they are used for.

Later in the show, Esther Racoosin speaks with Dr. David Shmoys, Professor in the Cornell School of Operations Research and Information Engineering.  He is also a faculty member in the Department of Computer Science and is the Associate Director of the Institute for Computational Sustainability.

He talks about his recent research article, “Analytics and Bikes: Riding Tandem with Motivate to Improve Mobility.”

LSS 74: Fiber Science

With the season’s chilly weather requiring people to wrap up warm, it seems like a good time to talk about fibers and fabric. In this episode, first, you’ll hear Liz Mahood present a history of the creation and production of synthetic fibers. To learn more about this intriguing science history, see the links below.

Later in the show, Esther Racoosin interviews Dr. Mike Haaf, Professor of Chemistry at Ithaca College. Dr. Haaf recently published a research article in the journal Coloration Tech. It is titled, “In situ fabric coloration with indigo synthesized in flow”. The co-authors of the paper are Ithaca College graduate Katrina Piemonte, Dr. Tyler McQuade of Virginia Commonwealth University, and Lucy Cotton and Richard Blackburn of the University of Leeds in the UK.

In his paper, Dr. Haaf  and collaborators describe a new method for synthesizing indigo dyes. The method allows for direct coloration of cotton fabrics without using a typical vat dyeing process that is used in the garment industry to dye denim jeans.

LSS 73: Science at the Museum

First, you’ll hear Patricia Waldron’s interview of Denise Nicole Green, Assistant Professor in the Department of Fiber Science and Apparel Design and Director of the  Cornell Costume and Textile Collection .
Green talks about the “Fashion & Feathers” exhibit currently on display in the Human Ecology Building. The collection features fashions constructing using feathers, designs inspired by birds, as well as matching bird specimens from the Cornell Lab of Ornithology, and the Cornell University Museum of Vertebrates. The exhibit can be seen in the Human Ecology Building, level T display cases. For more information see the Fashion & Feathers event website.

Next, Esther Racoosin speaks with Bryan Danforth, Chair and Professor in the Department of Entomology at Cornell University, about the exhibit Bees: Diversity, Evolution, Conservation, currently on display at the Museum of the Earth at the Paleontological Research Institution in Ithaca. Danforth and Dr. Robert Ross of PRI are the curators of the exhibit. Helaina Blume of PRI is the designer and creator of the exhibit. Bees! Diversity, Evolution and Conservation was created with grant support from the National Science Foundation, or NSF and the Tompkins County Tourism Program. For more information, go to: the Paleontological Research Institute website.
