Yesterday we watched the closing ceremony for the Relativistic Heavy Ion Collider (RHIC) @brookhavenlab. For somebody like me, who started my Ph.D. in heavy ion physics in 2000, the year when RHIC started its operations, it was an emotional moment.

What a day! I started with an online talk at my former Ph.D. advisor's retirement workshop, and a few hours later I celebrated the successful Ph.D. defense of my student 🤩 I am reflecting on the impact that my advisor had on my life, and trying to propagate it forward to my own students.
