Does string theory describe all fundamental particles and forces? Can gravity and quantum mechanics be reconciled? How can theoretical models help us understand complicated systems?
Knowing no boundaries in the sciences, theoretical physicists seek to explain and predict the wonders of the physical and biological world. Theoretical physics brings together diverse scientists to understand both fundamental forces and particles, as well as an understanding of more complex systems from phases of matter to the human brain.
