The Fermilab colloquium introduces staff, users, students and members of the public to a wide range of scientific and science-related topics presented by notable speakers from across the country and around the world. Colloquia are open to the public.

An integral part of Fermilab’s academic culture, “orange” colloquium talks are aimed at a broad scientific and technical audience, while “green” talks are of general interest to all laboratory staff, users and members of the public.

Colloquia are open to everyone. Unless otherwise advertised, the talks are held at 4 pm on Wednesday afternoons in the One West auditorium in Wilson Hall. Members of the public wishing to attend must show a photo ID at the laboratory entrance and tell the guard on duty that they are attending the colloquium.

Illinois’ landscape of home---the tallgrass prairie---has been viewed by people over time in many different ways. Historically, Native Americans saw prairie as grocery store, pharmacy, and a resource for everything from love charms to ceremonial treasures. Some early explorers saw it as a desolate, lonely place. Many early settlers saw prairie as a place to be conquered. Artists, musicians, photographers and other creatives see the prairie as a place for inspiration. Developers may see it as a potential resource. Many of today's researchers, site managers, and stewards view the tallgrass prairie as a place whose past holds keys to understanding our future. Listen to stories of how the tallgrass prairie has been viewed by people over time, as you reflect on how you and others "see" prairie today.

The Sloan Digital Sky Survey (SDSS) has been mapping the universe for about 20 years at Apache Point Observatory (APO), through four phases of operation and with an evolving and expanding suite of capabilities. I will review its legacy in mapping large scale structure in the galaxy distribution, which was one of the key goals of the project at its beginning at the time of Fermilab's leadership, and which SDSS will finish its observations of in early 2019. I will describe how SDSS will continue to study the astrophysics of stars and galaxies using a unique suite of instrumentation at both APO and at Las Campanas Observatory, where we are now also operating. These surveys are measuring the dark matter content, stellar formation history, ionized gas properties, and internal structure of the Milky Way and nearby galaxies. The fifth phase of the program, SDSS-V, will greatly expand these investigations at both observatories with new capabilities allowing a more rapid and complete coverage of the entire sky.

Mitakuyepi- my relatives. The Black Hills of South Dakota is known as He Sapa or Paha Sapa to my ancestors, my people, the Lakota. The Lakota and other Tribal Nations have had special ties to this area for thousands of years. For the Lakota, the Black Hills are the heart of everything that is, the center of our universe, where special sites remain vital to our existence. It is the responsibility of the Oceti Sakowin, the Seven Council Fires, to protect and preserve these sacred places where our Lakota ceremonies are held. We hold them with reverence, where we come to pray, not play. The Black Hills remind us to be respectful of Grandmother Earth and all that is. For indeed, we are all here for a purpose. Mitakuye Oyasin – For all my relatives/We are all related.

Paleontology has become an increasingly analytical science. In this presentation I will discuss how fractals and related concepts can be applied to our understanding of patterns in the history of life Specifically, I will describe 1) a simple fractal model can be used to understand the amount of time represented in a sequence of rocks;...

Medical physicists working in Radiation Oncology are involved in day-to-day clinical tasks including safety and quality assurance, accelerator maintenance, software and new treatment technique development. Historically, clinical research and development focused on making radiation delivery more precise, introducing hardware improvements, radiation intensity modulation, and image guidance during treatment. The next frontier in precision medicine is... More »
