Seamless Colloquium: Our perceptual limits in reading and interpreting visualizations

Aug 15, 12:30pm


Phillips Auditorium

Visualizations help us in interpreting and communicating complex concepts and rich data. However, we have a number of perceptual and cognitive limitations that counter-intuitively work against us when we work with visualizations. These limitations lead to critical mistakes, e.g., in interpreting patterns or simply reading information from a graphic. What are these culprits and how can we avoid them?

Seamless Colloquium: Concerning Astrophotography

Jun 26, 12:30pm


Phillips Auditorium

In this talk, Vicent Peris will review his works in the astrophotography and image processing disciplines. Working as astrophotographer at the Astronomical Observatory of the University of Valencia, he leads an astrophotography project at Calar Alto Observatory in southern Spain. This is the first astrophotography project in the world with access to the observational time of professional telescopes (about 50 night per year).

Seamless Colloquium: Why the LSST will change astrophysics forever, Arfon Smith (Github)

Pratt Conference Room, Harvard-Smithsonian Center for Astrophysics, 60 Garden Street

Abstract: As the flagship next-generation optical survey telescope, LSST promises to be a significant instrument for a range of research domains. In this talk I'll discuss why LSST is uniquely placed to transform the way that researchers collaborate around research software and data.

Seamless Colloquium: Linking Visualization & Understanding in Astronomy


Phillips Auditorium, Harvard-Smithsonian Center for Astrophysics, 60 Garden Street

In 1610, when Galileo pointed his small telescope at Jupiter, he drew sketches to record what he saw. After just a few nights of observing, he understood his sketches to be showing moons orbiting Jupiter. It was the visualization of Galileo’s observations that led to his understanding of a clearly Sun-centered solar system, and to the revolution this understanding then caused.
