There are some really cool advancements in light transport research: first, a technique that enables us to capture the propagation of light as an electromagnetic wave as it illuminates our world. There is a never-before-seen example I am really fond of: strictly speaking, if you stand in front of a mirror, there is a moment while you’re already standing there, but your image in the mirror is not visible yet. This phenomenon exists due to the finite propagation speed of electromagnetic waves and only lasts for a few nanoseconds, and is now caught on tape (around the one minute mark). I never thought this would be possible in my lifetime! Recently, Adrián Jarabo and colleagues built a rendering algorithm that replicates this behavior. It takes quite a bit to get my jaw dropped with novel research works, and it never ceases to amaze me that it still happens all the time.
