Quantum Mechanics 8 - What is a Photon?
Richard Epp - University of Waterloo
PIRSA:08080083By applying our understanding of the quantum harmonic oscillator to the electromagnetic field we learn what a photon is, and are introduced to “quantum field theory” and the amazing “Casimir effect.” Learning Outcomes: • Understanding that classical electromagnetic waves bouncing around inside a…
Special Relativity 8 - Applications of Minkowskian Geometry
Richard Epp - University of Waterloo
PIRSA:08080067Learning to use Minkowskian geometry to understand, very simply, a variety of aspects of Einstein’s spacetime. Learning Outcomes: • How a straight line is the longest path between two points in spacetime. • How a light particle experiences space and time: its journey from one location in the…
Special Relativity 9- Synchronization of Clocks
Richard Epp - University of Waterloo
PIRSA:08080068A discussion of how to synchronize clocks that are separated in space, and how this leads to the relativity of simultaneity. Learning Outcomes: • Understanding that clock synchronization is a physical process, and exploring various methods of synchronization using spacetime diagrams. • How to…
Special Relativity 7 - Minkowskian Geometry
Richard Epp - University of Waterloo
PIRSA:08080066Space obeys the rules of Euclidean geometry. Spacetime obeys the rules of a new kind of geometry called Minkowskian geometry. Learning Outcomes: • Triangles in spacetime obey a Pythagoras-like theorem, but with an unusual minus sign. • The true nature of time as geometrical distance in spacetime. •…
Quantum Mechanics 4 - OR vs. AND
Richard Epp - University of Waterloo
PIRSA:08080079Highlighting the essential difference between the classical and quantum worlds. Learning Outcomes: • A recap of what we’ve learned so far. • Understanding that in the classical world we have either “particle moving to the right” OR “particle moving to the left.” • Understanding that, in the quantum…
Quantum Mechanics 5 - The Heisenberg Uncertainty Principle
Richard Epp - University of Waterloo
PIRSA:08080080A discussion of the Heisenberg Uncertainty Principle as another way to understand quantum weirdness. Learning Outcomes: • Some deeper insights into what a particle probability pattern means. • The Heisenberg Uncertainty Principle gives a limit to the precision with which we can simultaneously know…
Quantum Mechanics 6 - The Strong and Weak Interpretations of Heisenberg Uncertainty Principle
Richard Epp - University of Waterloo
PIRSA:08080081A more in depth discussion of what the Heisenberg Uncertainty Principle is trying to tell us about the nature of reality. Learning Outcomes: • Understanding the strong interpretation of the HUP: “Particles cannot simultaneously possess a definite position and a definite momentum.” • Why the…
Special Relativity 6 - Doppler Shift for Light
Richard Epp - University of Waterloo
PIRSA:08080065Deriving the Doppler shift for light, from which all of special relativity follows. Learning Outcomes: • Return to the thought experiment in SR-3. By replacing Newton’s assumption of Universal Time with Einstein’s Relativity Principle we arrive at the Doppler shift for light. • How the Doppler shift…
Special Relativity 4 - Einstein's Speed of Light Principle ("Principle 2")
Richard Epp - University of Waterloo
PIRSA:08080063Repeating the experiment from SR-3 using light rather than sound, and understanding what Einstein assumed regarding the speed of light. Learning Outcomes: • How to draw a spacetime diagram that represents the sending and receiving of a light signal. • Understanding that Einstein's Speed of Light…
