Today We Have a Renaissance in Theoretical Physics. Join the Party!
The lesson of the experiments of the last few years is that the standard model of particle physics as it was in the mid 70s is perfectly adequate.
Lee attended Harvard University for graduate school receiving a Ph.D. in theoretical physics in 1979. He held postdoctoral positions at the Institute for Advanced Study in Princeton, The Institute for Theoretical Physics (now KITP) in Santa Barbara and the Enrico Fermi Institute at the University of Chicago. This was followed by faculty positions at Yale, Syracuse and Penn State Universities, where he helped to found the Center for Gravitational Physics and Geometry. In September of 2001 he moved to Canada to be a founding member of the Perimeter Institute for Theoretical Physics, where he has been ever since.
Lee's main contributions to research are so far to the field of quantum gravity. He was, with Abhay Ashtekar and Carlo Rovelli, a founder of the approach known as loop quantum gravity, but he has contributed to other approaches including string theory and causal dynamical triangulations. He is also known for proposing the notion of the landscape of theories, based on his application of Darwinian methods to Cosmology. He has contributed also to the foundations of quantum mechanics, elementary particle physics and theoretical biology. He also has a strong interest in philosophy and his three books, Life of the Cosmos, Three Roads to Quantum Gravity and The Trouble with Physics are in part philosophical explorations of issues raised by contemporary physics.
It’s a great time to go into theoretical physics. We’ve just passed through a period which was not such a good time to be a theoretical physicist in which we had several decades in which theory got way ahead of experiment. And it took experiment a while to catch up.
Now that we have the Large Hadron Collider and we have planck on the scale of cosmology - and we have actually many other new experiments which are not so famous - we’re able to check many of the spectors of ideas of the last 30, 40 years. And so far none of them turn out.
The lesson of the experiments of the last few years is that the standard model of particle physics as it was in the mid 70s is perfectly adequate. The Higgs has been discovered. And so there’s a kind of clearing the table for new ideas which should come from new people.

Both schizophrenics and people with a common personality type share similar brain patterns.
- A new study shows that people with a common personality type share brain activity with patients diagnosed with schizophrenia.
- The study gives insight into how the brain activity associated with mental illnesses relates to brain activity in healthy individuals.
- This finding not only improves our understanding of how the brain works but may one day be applied to treatments.
It's a development that could one day lead to much better treatments for osteoporosis, joint damage, and bone fractures.
- Scientists have isolated skeletal stem cells in adult and fetal bones for the first time.
- These cells could one day help treat damaged bone and cartilage.
- The team was able to grow skeletal stem cells from cells found within liposuctioned fat.
Gut bacteria play an important role in how you feel and think and how well your body fights off disease. New research shows that exercise can give your gut bacteria a boost.
- Two studies from the University of Illinois show that gut bacteria can be changed by exercise alone.
- Our understanding of how gut bacteria impacts our overall health is an emerging field, and this research sheds light on the many different ways exercise affects your body.
- Exercising to improve your gut bacteria will prevent diseases and encourage brain health.
