She says: It's better to light a candle than to curse the darknessLink (via Ambiguous)
He says: I wouldn't be so sure, maybe a candle would destroy your night-vision - without the candle your eyes could adjust to the lowered light levels (a process called adaptation, [Hack #26])
She says: But if you're in total darkness, there's no light at all to adjust to seeing
He says: Good point, so maybe it should be "It's better to wait for a bit, then, if your eyes don't adjust, you should light a candle rather than curse the darkness"
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
