Science is more important in our society than ever before. Science forms the basis for our technology, health care, transportation, and many other aspects of our daily lives; it even features in our politics and public policy. This series will connect select researchers -- who have expertise in science and in communicating about science -- with members of the public interested in learning more about, and discussing, science. How does science work? How does science impact our lives? What are the limitations of science? Come to our sessions, and experience Science Revealed!

Annette Vee is Associate Professor and Director of the Composition Program in the Dietrich School's Department of English, where she teaches undergraduate and graduate courses in writing, digital composition, materiality, and literacy. Her teaching, research and service all dwell at the intersections between computation and writing. She is the author of Coding Literacy (MIT Press, 2017), which demonstrates how the theoretical tools of literacy can help us understand computer programming in its historical, social and conceptual contexts. Her work is read in dozens of university courses in literacy, composition, textual studies, digital humanities, and computer science education.
Her current research examines the ways that computational technology is supplanting traditional realms of writing and rhetoric such as in law and commerce. She is at work on projects that consider the history of the Basic programming language; how blockchain technology affects rhetorics of trust; and how computational algorithms that write and read are affecting human writers and relationships. Past work has explored the role of bots online to spread fake news, the connections between computation and rhetoric, and the strange status of computer code as a form of writing protects by both copyright and patent law.

His work has mainly centered on using mathematical models to understand how cognitive processes emerge from biological structures.
"Reaping What We Spill, Leak and Spew"
Monday, February 6, 4 -5:30 p.m. EST
There is no doubt that humans impact the health of the environment and that the environment, in turn, impacts human health. Where consensus can break down is in deciding how urgent it is to respond to these impacts and what form this response should take. This is where science and data become indispensable.
In "Reaping What We Spill, Leak and Spew," our expert panelists from various schools at the University of Pittsburgh will discuss how researchers can measure levels of contaminants in the environment, how they can determine the health effects that result, and how these factors are or can be affected by policy and regulations. Come join us to hear from and engage with these experts on these crucial issues!

"UFOs and the Stories We Tell About Them"
April 7, 2022, 7-8:30 p.m. EST
UFOs have long fascinated us. Although most reports of UFOs have terrestrial explanations, they have spawned a good deal of speculation about extraterrestrials. The many ways in which we try to make sense of UFOs are just as interesting as the UFOs themselves!
Come listen to our panel of multidisciplinary experts from departments across Pitt's Dietrich School to get perspectives about how people in the middle ages might have conceptualized UFOs, how misinformation persists about ETs building ancient edifices, how our cognitive processes and biases work in making sense of UFOs, the likelihood of travel from exoplanets, the latest on a US intelligence report on UFOs, and how to detect nonsensical claims.

"Nothingness: So much to talk about!"
December 2, 2021, 8-9:30 p.m. EST
Words like “nothingness” and “empty space” may seem like simple concepts, referring to the complete absence of content. But in practice, these concepts have been topics of ongoing debate with important implications for our understanding of the universe. This panel discussion and Q&A at this event, involving several leading Pitt experts as well as our distinguished visitor James Owen Weatherall (author of the popular book Void: The Strange Physics of Nothing), will reveal in publicly accessible terms some of the complications and interesting ideas that arise when we try to get a grip on…nothing. What is (or is not) really out there? What are its properties? What shape does it take? Join us to find out a lot about nothing!
This event is presented in partnership with the University of Pittsburgh Center for Philosophy of Science and is free and open to the public. Please register to receive log in information for this Zoom Webinar event.

"Safety in Numbers? The Use (and Misuse) of Data in Society"
April 15, 2021
7 p.m. EST
Data is everywhere: from COVID efficacy rates to election polling, from the justice system to the internet.
Data can be a tool to improve our lives, but what about the downside to all of this use of data – not only through hacks and security breaches, but also when data is manipulated to advance certain political and social agendas?
Join Dietrich School faculty members Thomas Hales, Lucas Mentch, Sandra Mitchell, Lara Putnam, and moderator Lisa Parker for a lively conversation about the role that data plays in society--the good, the bad, and the life altering.
This event was recorded and is available for viewing.
Thomas Hales, Andrew Mellon Professor
Department of Mathematics
Topic: "Safe data with encryption"
Encryption uses math to keep data from falling into the wrong hands. In ongoing "crypto wars," some governments are fighting against strong encryption.
Lucas Mentch, Assistant Professor
Department of Statistics
Topic: "Data in the Justice System"
The abundance of data available today can be used throughout the justice system for everything from validating forensic science procedures, to investigating disparities in police killings, to creating algorithms to predict prison sentencing. What are the ways in which this can strengthen our trust in such institutions and what are the pitfalls we must be careful to avoid?
Sandra Mitchell, Distinguished Professor
Department of History and Philosophy of Science
Topic: “What data can and cannot tell us”
Scientific data from controlled experiments is the best source of causal information but it has limitations for application to everyday decisions and policies. The difference between judgments of efficacy and effectiveness of covid-19 vaccines exposes the additional considerations required in knowing HOW to use scientific data in different contexts.
Lara Putnam, UCIS Research Professor
Department of History
Topic: "Social Media and Social Movements: Crowdsourcing Knowledge, Combatting Disinformation”
The rise of social media has created new ways for people to learn about and join social movements. Researchers have kept step, creating new crowdsources platforms that enable us to seeing the scope and spread of protest movements like those supporting racial justice or opposing policies or regimes. But social media has also made it possible for disinformation and false narratives about protestors and social movements to spread: creating new challenges for democracies in a digital age.
