"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 [1]. 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."

We are taking a break

We regret that due to unavoidable reasons, we need to take a break. We'll not have our regular postings in next two weeks. Regular postings will resume on April 10th. In the mean-time, you may go through our past postings on various topics of interest. We suggest that you use the search box on top to search for past postings on topics of your interest (e.g. 'Einstein', 'Fusion', 'Nobel Prize', etc...)
