Light in the 21st Century: Waves, Particles and Noodles
Does star light travel through space in waves or as individual corpuscles or quanta? How is light affected as it races through space and time? The nature of light has confounded physicists since Newton decomposed it into its spectrum of colours in the 17th century. As physicists have delved deeper into the quantum nature of reality, they have revealed that space may not be empty -- instead, it may be a bubbling liquid of bizarre objects called "strings." In this new quantum theory, light itself emerges from waves in a background liquid of string loops. Other elementary particles, such as electrons, are created by the free ends of string loops which have broken apart. In this lecture, Professor Wen will describe how light and electrons emerge from this undulating liquid of strings - almost like the universe is created as a vast bowl of glowing noodles.

- Free on campus parking in Lot M
- Although tickets for this lecture are sold out, we expect that there will be some seats available due to "no-shows". To get in a waiting line please be at the Mike & Ophelia Lazaridis Quantum Nano Centre – University of Waterloo on Feb 25th no earlier than 6 pm. Please note you must arrive in person to be part of the waiting line.
- Due to high demand all ticket holders must be in their seat(s) by 6:45 pm. All tickets are no longer valid or usable at 6:45 pm and you will be asked to join the waiting line. Our best recommendation to ensure that you are in your seats by 6:45 pm is for you to be parking your car by 6:30 pm.
