Theoretical physics

Theoretical physics is the development of mathematical formalisms and computational protocols for describing all aspects of objects found in the world around us and their interaction. This can involve both providing models for understanding empirical results or constructing self-logical theories for explain phenomena beyond current experiments.

    Modern theoretical physics is indivisible. Ideas flow freely and fruitfully across traditional boundaries separating materials physics, fundamental physics and cosmology. How did this state of affairs come to be? What are its outstanding results? Is there more to come? Frank Wilczek discusses the synergy between the different fields of physics.

    The gravitational constant, G, which governs the strength of gravitational interactions, is hard to measure accurately. Two independent determinations of G have been made that have the smallest uncertainties so far.

    Neutrinos are tiny, ghost-like particles that habitually change identity. A measurement of the rate of change in high-energy neutrinos racing through Earth provides a record-breaking test of Einstein’s special theory of relativity.

    David Hilbert famously argued that infinity cannot exist in physical reality. The consequence of this statement — still under debate today — has far-reaching implications.
