    I had an interesting experience with my colleagues.  When looking through
the Johnson U filter, one of my colleagues called it "completely black",
while I could see the purple light.  Probably this may have originated from
the personal difference of UV sensitivity.  Through Kron-Cousins I filter,
I could only preceive very faintly.  Once in my career in physics experiment
course, I could visually measure a number of violet lines through a visual
spectrometer, but don't remember their exact wavelengths.

    Well, this may be exactly what is working in CV observers 'how do I
observe'.  But there seems to be a static neural flow towards outbursts,
with equal lots of turbulence and chaos within me...
