Like.
No, when you increase the resolution, you, of necessity and by definition, increase the number of pixels. Not a good analogy anyway... -
russ_watters reacted to Bandersnatch's post in the thread Does it make sense to build new radio telescopes? with Like.
While the SKA does list search for alien signals as one of its projects, I'd wager my hat on it being there mainly as a media angle. It...

russ_watters reacted to fresh_42's post in the thread Does it make sense to build new radio telescopes? with Like.
I got the impression that you think radio astronomy is meant to listen to alien radio shows. This is not even close to what it is meant...

russ_watters replied to the thread Cantilever help.A 17' span is pretty big too. This sounds to me like something that's illegal to do without a licensed structural engineer. So I'm...
