Light is a set of waves through space. So the “messages” are presented as waves. Each atom has its own way to send its message. This is its “spectra”… - Zohra Ben Lakhdar Akrout

In future, nothing should be impossible. I long to build a center for optics and photonics for African research scientists in Tunisia, just like the Trieste center.

Be aware of the importance of culture; be open-minded as a scientist and as a person. Seek independence. Understand how important it is to be a responsible citizen. Be of good heart and be confident.
