"About 200 femtoseconds after you started reading this line, the first step in actually seeing it took place. In the very first step of vision, the retinal chromophores in the rhodopsin proteins in your eyes were photo-excited and then driven through a conical intersection to form a trans isomer . The conical intersection is the crucial part of the machinery that allows such ultrafast energy flow. Conical intersections (CIs) are the crossing points between two or more potential energy surfaces."

2Physics.com publishes invited semipopular level articles on key developments
in various fields of Physics. Authors may submit semipopular level articles based on their own
research paper(s) published in refereed journal(s). Alternatively, they may consider sending a proposal
(one short paragraph) and a list of related publications before writing the full article. We will let you know our decision within a few days after we receive the proposal.
