From the Ted Talk by Marcus du Sautoy: Symmetry, reality's riddle

Unscramble the Blue Letters

Now it matters what order you do the operations in. And this enables us to distinguish why the symmetries of these objects — they both have six smmeeitrys. So why shouldn't we say they have the same symmetries? But the way the symmetries iraetcnt enable us — we've now got a lgnuagae to distinguish why these symmetries are fundamentally different. And you can try this when you go down to the pub, later on. Take a beer mat and rotate it by a qauetrr of a turn, then flip it. And then do it in the other order, and the picture will be facing in the opposite direction.

Original Text

Now it matters what order you do the operations in. And this enables us to distinguish why the symmetries of these objects — they both have six symmetries. So why shouldn't we say they have the same symmetries? But the way the symmetries interact enable us — we've now got a language to distinguish why these symmetries are fundamentally different. And you can try this when you go down to the pub, later on. Take a beer mat and rotate it by a quarter of a turn, then flip it. And then do it in the other order, and the picture will be facing in the opposite direction.
