For Family Weekend, Professor Benjamin Schumacher will discuss various impossibilities in physics and what they mean regarding our understanding of the world. Join us in Hayes Hall 211/213 at 12 p.m. for this exciting presentation on the impossible. If you cannot join us in person, feel free to join us virtually by following this Zoom link.

Some things are possible and some are not. That line between the possible and the impossible can tell us a lot about the way nature works. In this talk we will ponder a few impossibilities, from the famous (time travel) to the obscure (quantum cloning), using them to discover some of the physical principles that govern information in our quantum universe. As one might expect upon a journey into wonderland, our constant companion will be Alice — thanks to her creator Lewis Carroll and her most famous illustrator Sir John Tenniel. Many surprises will await us through the looking-glass of the impossible.
