Cute movie about the arrow of time in a quantum setting #entropy

Bill Phillips: public lecture at #FQMT19 “i’d like the children to come to the front row; it’s going to be a lot more fun and only a little more dangerous, let’s move the VIPs out of the way, these kids are really the future”

@jenheemstra There's a stigma associated with getting a Masters from a program where this is not the terminal degree. Changing the way programs are organized might alleviate this stigma.

Yuval Gefen giving a beautiful and pedagogical talk explaining how weak measurements can be used to induce a geometric phase and the emergence of a topological transition. Combining two of my favorite topics; we're trying to do this experiment soon. #FQMT19

And what we found was surprising - even though quantum mechanics is time symmetric, a probabilistic arrow of time appears through the process of quantum measurement. (Phys. Rev. Lett. 123, 020502 – Published 9 July 2019), https://t.co/rAcGU8necY

What makes the future so different than the past? The past is known and the future is uncertain - yet the physical laws that govern both classical and quantum mechanics are fundamentally time symmetric - they don't distinguish the past from the future.

I was always curious about this, so we set out over the past 4 years to see what we could find. We just published our findings in @PhysRevLett. I made a brief video to describe our process. We're basically trying to find out if quantum movies look funny when played backwards.

"Reward excellent failure, punish mediocre success" -@tom_peters

I just said "nice work!" to someone with negative results. Why? Because they systematically attacked the problem and figured out what isn't working. If we want to make progress, we must embrace intelligent failure.

@NicholasFerroni Does my PHys Ed teacher count? 3rd grade.

@Afeig_novi @RCSA1 Just opened an account. I think that was what I was supposed to do.
