  • The Case for Cosmic Modesty 

    Loeb, Abraham (Avi) (Georgia Institute of Technology, 2018-03-12)
    Based on the premise that we are not special, Loeb argues for modesty from a cosmic perspective. His “principle of cosmic modesty” implies that both primitive and intelligent forms of life should exist away from Earth, and ...
  • Ice Fishing for Neutrinos 

    Halzen, Francis (Georgia Institute of Technology, 2016-09-12)
    The IceCube project at the South Pole has melted eighty-six holes over 1.5 miles deep in the Antarctic icecap for use as astronomical observatories. The project recently discovered a flux of neutrinos reaching us from the ...
  • The Birth of the Universe 

    Efstathiou, George (Georgia Institute of Technology, 2015-04-07)
    Modern physics attempts to explain the full complexity of the physical world in terms of three principles: gravity, relativity and quantum mechanics. This raises important fundamental questions such as why is our Universe ...
  • The Data and Compute-Driven Transformation of Modern Science 

    Seidel, Edward (Georgia Institute of Technology, 2011-10-13)
    We all know that modern science is undergoing a profound transformation as it aims to tackle the complex problems of the 21st Century. It is becoming highly collaborative; problems as diverse as climate change, renewable ...
  • Aeons Before the Big Bang? 

    Penrose, Roger (Georgia Institute of Technology, 2009-03-24)
    There is much impressive observational evidence, mainly from the cosmic microwave background (CMB), for an enormously hot and dense early stage of the universe referred to as the Big Bang. Observations of the CMB are now ...
