1) Roger Malina discusses how entering an era of "big data" has changed astronomy and the scientific method, discovering dark matter and relying more on data analysis and simulations than physical experiments.
2) He argues that our tools and data are reshaping our understanding of the world in fundamental ways, and we need new metaphors to conceptualize these changes, such as "networks of networks" or an "age of entanglement."
3) Malina's ArtSciLab at UT Dallas explores multi-modal representations of large datasets through projects like sonifying brain network data and creating "data forests" interactive visualizations to develop new understandings of data.
