STEM in Action at Fermi National Accelerator Laboratory

fzsAux3v8zBmXYYBzROO1KdAPBWkGuYmb-d2_bK4C1Q[1]STEM – science, technology, engineering, and math – is a focus area for educators at the global, national, state, and local levels, and has been a significant point of emphasis for us here at ADM.  ADM High School’s PLTW engineering, biomedical science programs, and soon-to-be-added computer science programs, along with ADM Middle School’s PLTW-sponsored Gateway to Technology program, have helped our district to provide students with an opportunity to explore STEM fields that is matched by few other schools in the state.  While we know that STEM-field career opportunities are growing at a much faster rate than the economy as a whole, I was excited to have the opportunity to visit the U.S. government’s Fermi National Accelerator Laboratory in Batavia, Illinois (Fermilab) recently, where I saw the application of the skills and principles we’re instilling in our students in a working, scientific environment.

tevatron_voloFermilab – a U.S. Department of Energy national laboratory focusing on high-energy particle physics – was founded in 1967 on the outskirts of Chicago, and is known worldwide as the home of the Tevatron, a high-energy particle accelerator that was the world’s highest energy accelerator from 1983 until 2010, when it was surpassed by the Large Hadron Collider at CERN in Switzerland.  The Tevatron ceased operations in 2011, but during its 28 year run was responsible for a number of discoveries, including the discovery of the top quark – a particle in the Standard Model of particle physics – in 1995.  The first observations of the Higgs Boson were made using the Tevatron, and Fermilab researchers announced in 2012 that they had narrowed the range of mass for the Higgs to 115 to 135 GeV.  Two days later, physicists at CERN announced the discover of the Higgs Boson with a mass of 125 to 126 GeV.

Physicist Marc Weinberg explained his experimental work searching for evidence of supersymmetry, which theorizes that every type of particle has a corresponding superpartner, none of which have yet been discovered.  In order to design and implement innovative new experiments, Dr. Weinberg works with theoretical physicists to establish the theoretical framework within which he’ll work, collaborates with other experimental physicists to devise new ways to test these theories, and coordinates with the engineers who will be responsible for design and construction of the equipment necessary to perform the experiments.  Once data begins to come in from an experiment, computer scientists and mathematicians are instrumental in collection and analysis of the results.
