The Interaction between Very Short Laser Pulses and Materials - Eric Mazur 

do i see a feynmans lectures on physics in the background?

non-linear propagation in otherwise transparent media produces fascinating phenomena; such as drastically changing the refraction index( changing the speed of propagation)

@ 3:20 The physical gestures must convince you, hihi. 1. In the Sun? 2. On its surface? 3. 6000K is nothing. Who is fooling who here?

interesting

very good speech, but very bad "translation" in the subtitles
