It's said by Cave Johnson -- an character in Portal2. Full voice line is:
"Just a heads up: We're gonna have a superconductor turned up full blast and pointed at you for the duration of this next test. I'll be honest, we're throwing science at the wall here to see what sticks. No idea what it'll do. Probably nothing. Best-case scenario, you might get some superpowers. Worst case, some tumors, which we'll cut out."
I don't understand throwing science at the wall
. In my opinion, what we throw should be a real thing (a ball, a stone), but science
is an abstract concept, how could we throw it at the wall? And how could science (or something) stick to the wall?
Please give me some hints to understand that.
