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 can Hiroshima be inhabited when Chernobyl cannot?
Actually Chernobyl is already kinda safe now. Typical radiation levels are only 1 uSv/hour and lower, peaking to 10 uSv/hour in the area near to reactor itself. There are populated cities with higher ambient radiation levels. So it's not inhabited only because of intertia, fear and bureaucracy. BTW I lived for 15 years 100km from Chernobyl.

comment Spallation neutron generation and pure U-238 reactors
Well, this is not ADS. The difference is that we are not waiting for accumulation of fissile isotopes, but rather burn U-238 directly using relativistic neutrons.

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.
