Regular readers of the magazine will be familiar with “Lateral Thoughts” – Physics World’s long-running column of humorous or otherwise offbeat essays, puzzles, crosswords, quizzes and comics, all written by our readers – that appears on the back page each month. For this month’s special issue on the theme of “time – the abiding mystery”, siblings Eugenia Viti and Ivan Viti have crafted a comic that takes a wry look at the physics and metaphysics of time. Eugenia is a cartoonist, illustrator and writer living in Chicago. Follow her on instagram (ayokdit) to see how much pizza she eats. It’s a lot. Ivan has a PhD in physics and is currently working as a postdoctoral researcher at the University of Notre Dame, Indiana. He lives with his wife, two cats, two dogs and one goldfish.
