Hello everyone,

YouTube personalities, the "Vlogbrothers", have a video of how one could encode and decode all of English Wikipedia onto a QR code. It's fantastic!

t: How large would a QR code need to be to scan all 24 trillion bytes of English Wikipedia?

t: Vlogbrother @johngreen does the math of how to fit English Wikipedia – on a QR code? 

F/G: How big would the QR code need to be to fit all 24 trillion bytes of English Wikipedia? We'd have to put it on the moon.

F/G: Vlogbrother John Green tackles the math and physics of encoding and decoding Wikipedia ...onto a QR code.

F/G: The QR code for all of English Wikipedia is so large it would have to be placed on the moon. 

Thanks for reviewing!
