10 of Futurama's smartest science references and gags

"Futurama" co-created by "The Simpsons " mastermind Matt Groening has been packed with smart science references.

The show's writers have also managed to squeeze in plenty of ingenious references to physics, mathematics and other branches of the sciences.

These have varied in complexity across the show's run, ranging from simple sight gags to jokes directed at mathematicians.

1729 is the most famous Ramanujan-Hardy number, the smallest that can be expressed as the sum of two positive integer cube numbers in more than one way.

In season three episode " The Luck of the Fryish ", electron microscopes are used to separate a dead heat in a horse race at Flushing Downs .

The 0 in the name of futuristic cinema chain Loew's 0-Plex refers to aleph-null, which is the smallest infinite cardinal number.

In season eight episode "Benderama" Professor Farnsworth invents the Banach-Tarski Dupla-Shrinker, a machine capable of creating two smaller copies of an object.

Bender sees the machine as an opportunity to duplicate himself.

These duplicates then duplicate themselves into more duplicates, who duplicate themselves (ad infinitum) until the Earth is overrun by millions of tiny nano-Benders.
