    • The Origin of the Universe and the Arrow of Time 

      Carroll, Sean M. (Georgia Institute of Technology, 2016-04-11)
      One of the most obvious facts about the universe is that the past is different from the future. We can remember yesterday, but not tomorrow; we can turn an egg into an omelet, but can't turn an omelet into an egg. That's ...

      Goldbart, Paul M. (Georgia Institute of Technology, 2016-11-14)
      The gases, liquids, and solids that humans have known and harnessed since prehistory are human-scale reflections of how atoms and molecules are organized at the atomic scale. This organization is driven by the forces exerted ...
    • The Physics of Genes and the Promise of Personalized Medicine 

      Aksimentiev, Alek (Georgia Institute of Technology, 2016-11-17)
      The twenty-first century is poised to see dramatic advances in medicine. The rapid after water and oxygen, is the most famous molecule of life known. This is not surprising, as the eye-catching double helix of DNA carries ...
    • Purls of Wisdom: The Geometry and Topology of Weavables, Wearables and Wallpaper 

      Matsumoto, Elisabetta (Georgia Institute of Technology, 2016-11-28)
      Curved space and bizarre mathematical worlds beyond Euclid’s axioms entered physics with Einstein’s general theory of relativity. But these geometries are all around us, hiding in plain sight, in the guise of familiar ...
    • The Square Kilometre Array: Big Telescope, Big Science, Big Data 

      Taylor, Russ (Georgia Institute of Technology, 2017-01-23)
      The Square Kilometre Array (SKA) is a next generation global radio telescope currently undergoing final design by a collaboration of institutions in 11 countries. The SKA will be one of the largest scientific projects ever ...

    • The Ig Nobel Prizes and Improbable Research 

      Abrahams, Marc (Georgia Institute of Technology, 2017-10-11)
      The Ig Nobel Prizes honor achievements that make people LAUGH, then THINK. Ten new prizes have been awarded every year since 1991, in gala ceremonies at Harvard and MIT, with winners traveling from around the world, and ...
    • Einstein's Cosmos and the Quantum: Origin of Space, Time, and Large-Scale Structure of the Universe 

      Ashtekar, Abhay (Georgia Institute of Technology, 2017-11-14)
      For over two millennia, civilizations have pondered over the questions of cosmogenesis. But serious attempts to address them began only with Einstein's discovery of general relativity a century ago. Advances over the past ...
    • From Molecules to Migration: How Quantum Physics Can Explain the Compass of Birds 

      Ritz, Thorsten (Georgia Institute of Technology, 2018-02-05)
      The world of quantum physics appears mysterious, even spooky, and far removed from everyday phenomena we can observe in the world around us. Especially the realm of living organisms was thought to be far too disorganized ...
