"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."

This is THE YEAR OF PHYSICS
2005 is the year of Physics.
Here you will find exciting facts and information regarding
latest advancements in research, education and use of Physics
in Technology and daily life.
We will also post interesting stories about scientists and
So, check out from time to time. You may not be an expert
in Physics. But you will like it. After all, how can you avoid
knowing in simple terms how small things like electron and
big things like the universe are working around you.
Keep your comments if you donot understand something.
