"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."

'Inertial Confinement'

The "inertial confinement" technique uses lasers or ion beams rather than
magnets to confine the plasma. This will be investigated by the National
Ignition Facility (NIF) in the US and the Laser M├ęgajoule (LMJ) in France.
However, both these billion-dollar lasers will primarily be used for nuclear
-weapons research, with only 15% of their time being available for other
areas of physics. In this conventional approach to inertial confinement, the
lasers that compress the fuel capsule also heat it.

Hi,

Can you post some links and details about such topics.

IMO, it really doesn't serve the purpose when your posts are this short. Just my 2 cents.

Thanks for the links. The link to ucb IFE details the whole concept and the programme with the limitations behind it.

I really appreciate your effort !
