Our University is closed today as well as most of the state organizations: we observe the holiday - Independence Day - which, in fact, is happening tomorrow. In addition, it was raining all night and all morning. And still I did come to the lab at 8 am, since I have to carry out an experiment. The scary thing is that I not just have to, I want to do it.

I pour the liquid nitrogen to cool down the detector, pump the vacuum and cool down a sample, turn on the laser, focus the laser beam on the sample's surface, maximize the PL signal, and take the spectrum... In a dark room... Only scattered green laser light... The light is my tool to probe the nature.

Facts speak for themselves: I am a science geek !!!
