Nature & Animals Quote by Brian Greene

"No matter how hard you try to teach your cat general relativity, you're going to fail"

About this Quote

The joke lands because it flatters and deflates us at the same time. Brian Greene, a physicist who spends his public life translating cosmic abstractions into human language, picks the most domesticated symbol of inscrutable indifference - the cat - and uses it to puncture a very modern fantasy: that intelligence is just a matter of effort plus the right TED Talk.

On the surface, its a throwaway line about feline stubbornness. Underneath, its a sly defense of cognitive limits. General relativity isnt merely "hard"; its conceptually alien, requiring mathematical scaffolding and a willingness to abandon everyday intuitions about time, space, and gravity. Greene is reminding us that understanding is not evenly distributed across minds, species, or even individuals. Some frameworks cant be brute-forced into existence by willpower.

The cat matters because it has become internet shorthand for a creature with personality but no interest in our projects. By choosing it, Greene reframes science communication: the obstacle isnt just complexity, its the mismatch between a mind and the concepts being offered. That subtext neatly rebounds onto humans, too. If a cat cant be trained into Einstein, neither can everyone be converted into a physicist, and thats not an insult; its an argument for intellectual humility.

Contextually, the line fits Greenes broader mission: celebrate wonder without selling false accessibility. Science isnt sacred because everyone can master it, but because it shows us how far cognition can stretch - and where it stops.

No matter how hard you try to teach your cat general relativity, you're going to fail.. This line appears verbatim in PBS NOVA’s online interview “A Conversation with Brian Greene,” part of the companion website for NOVA’s 3-hour miniseries The Elegant Universe. The page footer indicates it was “Created July 2003,” which is the earliest primary publication instance I could verify for this exact wording on an authoritative, first-party source. Within the interview it is spoken by Greene in response to NOVA’s question about limits to human knowledge of the universe.
