Origin of light (and other elementary particles) -- a unification of matter and information

Our world have a lot of mysteries: Why all interaction are gauge interactions? Why all matter elementary particles (such as electrons and quarks) are fermions. Why we have many symmetries even though quantum fluctuations of gravity violate all of them? We find that all those mysteries come from (or can be resolved by) quantum entanglement of many qubits, that form our space. Quantum entanglement of many qubits (the origin of mysteries) is a new physical phenomenon that requires new mathematics -- braided fusion higher category -- to describe, which also becomes the mathematical framework for quantum symmetry .

The Colloquium Ehrenfestii takes place Wednesday evenings starting at 19:30 hours in the main auditorium of the Oort building. Before the Colloquium, there is a common dinner in the canteen located on the ground floor of the Oort building. This dinner starts at 18:00 hours sharp and is free of charge, under the condition that one attends the colloquium and that one has made a reservation before noon on the Tuesday preceding the colloquium.

We count on your presence if you register, please do show up. Meal registrations may close earlier, when 80 persons have signed up.
