Joseph Silk is Homewood Professor of Physics and Astronomy at Johns Hopkins University. He studied at Cambridge and earned his PhD from Harvard in 1968. Silk was a postdoctoral fellow at Cambridge and Princeton, and taught at the University of California, Berkeley, and the University of Oxford. He joined Johns Hopkins in 2010. Silk has written or co-authored more than 500 publications. He has conducted important early work on homogeneities in the cosmic microwave background and how they are influenced by density fluctuations in the matter of the early universe, in particular by a damping effect that bears his name. Silk was awarded the 2011 Balzan Prize for his pioneering work on the infant universe.
The fine-tuning of the constants of nature, which seems required for the existence of stars and planets and certainly for life and mind, is a fascinating feature of our...
Physics of Fine-Tuning
What enables structures to form in the universe? How did galaxies, stars and planets develop from the primeval plasma soup? What are the laws of nature that bring about...
Fine-Tuning in Cosmology
Cosmology is the study of the structure, beginning and end of the universe, and it has been transformed from mostly metaphysical speculation to a precision observational...
