Am i the only one who think of the ne555? 21:46, 11 December 2012 (UTC)

No idea. What I was thinking was who reads books like that?

(There again who responds to sites like this?) And: Shouldn't the mirrors be at a slight angle to one another? I used Google News BEFORE it was clickbait (talk) 18:06, 30 January 2015 (UTC)

He refers to the NE555, the most famous IC, used mainly to create timers and oscillators. Its use matches perfectly the comic's theme. In fact, I came to this Discussion section expecting a reference to the NE555. Ajgelado (talk) 05:33, 1 September 2016 (UTC)
A slight angle would amplify with each reflection breaking the chain. It would make more sense for them to be parallel but off-center from one another. flewk (talk) 07:38, 5 January 2016 (UTC)
