“Jakob sends Rakel a text message that contains a link to the xkcd webcomic. The cartoon, titled “Angular Momentum,” shows a girl spinning around and around next to a bed on which her boyfriend is sitting and watching her in amazement.
“What are you doing?” his speech bubble says.
“Spinning counterclockwise. Each turn robs the planet of angular momentum, slowing its spin the tiniest bit, lengthening the night, pushing back the dawn, giving me a little more time here, with you,” answers the spinning girl.
Rakel is amused and sends Jakob a response: “Right now I’m spinning the other way, clockwise with the earth’s rotation. All in the hope of making our planet turn the tiniest bit faster, so that time will pass more quickly and it won’t be so long until I see you again.”
“Cunning—you can spin both ways” is his answer.”
