I always loved physics. But because I found something even cooler for a profession I just stayed an amateur physicist. Gravity, waves, particles, strings and relativity make my eyes shine and sometimes my head spin.

Perhaps I love physics for the same reason Newton did: "I can calculate the motion of heavenly bodies, but not the madness of people."

And in the night time, when I go for the last walk with my dog and I look at the stars I remember Fox Mulder: "The truth is somewhere out there..."

[PS: I use Desktop Spectrometry Kit v3.0 with the JDEPC-OV04 webcam.]
