High precision for studying the building blocks of the universe

    From Exascale Computing Project, May 28, 2019: Fermilab scientist Andreas Kronfeld is featured in this piece on the Excascale Computing Project, quantum chromodynamics and lattice QCD. Kronfeld, the principal investigator of ECP’s LatticeQCD project, explains how exascale computing will be essential to extending the work of precision calculations in particle physics to nuclear physics. The calculations are central for interpreting all experiments in particle physics and nuclear physics.

    Falsifiability and physics

      Can a theory that isn’t completely testable still be useful to physics? What determines if an idea is legitimately scientific or not? This question has been debated by philosophers and historians of science, working scientists, and lawyers in courts of law. That’s because it’s not merely an abstract notion: What makes something scientific or not determines if it should be taught in classrooms or supported by government grant money.

      All hands on deck

        Some theorists have taken to designing their own experiments to broaden the search for dark matter. The trend of theorists proposing experiments has become so common that it’s almost expected of new students entering the field. The hope is that flooding the field with new ideas could finally lead to the discovery of dark matter.

        What the heck is dark matter?

          From PBS Digital Studios’ The Good Stuff: Dark matter makes up 70 percent of the known universe, and we know very little about it. This video on dark matter includes an interview with theorist Patrick Fox and a tour of the MINOS underground area at Fermilab.
