Recently, a robot vacuum in England made a dash for freedom. Unbeknownst to staff, it popped over the lip at the entrance, and then took off. That’s a fun little story, certainly, but it was this quip that really stood out to me.

While some readers joked about the robot’s adventures, one feared for its safety in the great outdoors, pointing out that “nature abhors a vacuum”.

If Aristotle knew his work would be remembered almost 2,500 years later, and used thusly, he would surely be proud.
