Software developer (in love with C++). Hardware geek (FPGA's, STM32, AVR, crazy stuff from discrete components), love LED indicators (7-segment, alphanumeric). Trying to understand ASIC design & manufacturing better at the moment. Also, trying to wrap my head around lens design, but that is not going to be that easy.

comment Why is water clear?
@PatrickM Hydrogen fusion happens only in the core of the sun. Sun emit light just because it's surface is hot - so it's spectra is more or less continuous.

@user6972 Dielectrics have no free electrons - and do not reflect all light. Absorption bands for these hydrogen-oxygen bonds lie in UV and IR regions.

comment Calculating the number of quanta emitted as Cherenkov radiation in a wavelength interval dl?
This formula looks too simple at first glance. Currect formula should looks like this en.wikipedia.org/wiki/Frank%E2%80%93Tamm_formula and the most tricky part is to get correct function of refractive index of the material for deep UV region. Also see my question physics.stackexchange.com/questions/72446/…
