Coder, software architect, interest in computer science in general. Did research on computer graphics, ray tracing, radio wave and antenna simulation. Like to learn new programming languages. Currently doing Python and Emacs Lisp for fun. C++ for profit. Would like to learn more Clojure.

comment Why do black holes have jets and accretion disks?
I have very little understanding of black holes, but maybe the accretion disk is another effect produced by the conservation of angular momentum? Just like Protoplanetary disks, galaxies and so on.

comment How powerful a telescope would allow me to view the astronauts aboard ISS do a space-walk?
Well, it seems the angular resolution of a telescope can be approximated by the Rayleigh limit, which is 5.5/aperture in inches. So for 10 inch, this will be 0.55 arcseconds. And a quick search tells me that the ISS is about 37 arcseconds at 410km distance. So we get at least 67 clear ISS pixels out of the 10 inch telescope! Furthermore, using super-resolution techniques, we can achieve much better resolution than that.

comment How exactly is our universe mapped?
Are the two black slices in the diagram due to the milky way blocking our view?
