NPA Seminar, Simon Foreman, Perimeter Institute, "Detection of Cosmological 21cm Emission with CHIME"

Abstract: Intensity mapping of redshifted 21cm emission from neutral hydrogen holds great promise for learning about cosmology, as it provides an efficient way to map large volumes of the universe without the need to characterize individual luminous sources. The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is a cylinder telescope located in Western Canada that was custom-built for this purpose, and that has collected several hundred days’ worth of data since it reached full observational capacity in late 2018.

WIDG Seminar, London Cooper-Troendle, Yale, “Extraction of an Inclusive Muon Neutrino Charged Current Differential Cross Section at MicroBooNE”

The MicroBooNE detector is a Liquid Argon Time Projection Chamber (LArTPC) located along the Booster Neutrino Beam (BNB) at Fermilab. One of its key physics goals is the measurement of neutrino-Argon interaction cross sections. Due to the detector’s fully active volume as well as its capability to offer a high-efficiency neutrino event selection, MicroBooNE is well suited produce the first ever triple-differential neutrino-Argon cross section.

The Age of Living Machines: How Biology Will Build the Next Technology Revolution

With an anticipated world population of over 9.5 billion by 2050, we face an unprecedented challenge to sustainably provide sufficient food, water, energy and healthcare. Convergence, the merging of previously distinct disciplines, has emerged as a powerful model with untold potential to drive a new cycle of innovation-based economic growth. Bringing together insights and discoveries from the life, engineering, computation and physical sciences holds the promise of accelerating discovery and the development of new technologies to meet the 21st century’s needs.

What is a 'Cause,' and Why Does it Happen Before the Effect?

The physics of the time orientation of causation is more subtle than what it looks like superficially. For a long while it was reduced to a mere linguistic issue (a “cause” is just the term of a correlation that happens earlier, Hume). As emphasized by Russell, there is no time orientation in fundamental physics. But causation was later better understood as an essential notion in the context of an agent having choices, which after all is our own common context. This traces the time orientation of causation to the time orientation of agency.
