Queuing up for tonight's sold out (but streaming) Community Lecture by Fractal Faculty Professor @seanmcarroll!
🧵 Follow this thread as we look into Schröedinger's Box with @seanmcarroll (newly appointed to Chair of #NaturalPhilosphy at @johnshopkins) and learn about the #ManyWorlds hypothesis of #QuantumMechanics:

"Even if we're wrong, it's not magic, it's #physics, it's #science, and it can be understood."

"When we look at the world, we don't see the entirety of reality. What reality is, is the #superposition of the many different ways..."

"#Space is one of the many things in #reality."

1/ Here is a proposal of how to distinguish between different, supposedly "equivalent," #orthogonal mixtures of photons. In this case, it is R + L mix of circular, to be distinguished from mixtures of linear #polarization.

I am leaving aside right here whether it could lead to #FTL communication (#SuperluminalSignalling), and focusing on the bare being able to make the distinction. Impractical - but of major theoretical importance.
#ProperMixtures #MeasurementProblem
We use a compound detector D for this purpose. Its first element is a quarter-wave plate with horizontal fast axis, that is rotationally free within a small angle (to allow measurement of changes in #angularmomentum of roughly a few hundred ħ, which is still very tiny.)
