Sheldon starts eating Brussels sprouts to extend his lifespan. The diet gives him severe gas. He first mistakes the pain for appendicitis and tells Leonard he thinks his appendix is about to burst—then farts loudly and concludes it was the sprouts. Later, after he falls down the stairs while trying to jog with Penny, she helps him up and he farts in her face. His follow-up line is: “If it makes you feel any better, Thursday is no longer cruciferous vegetable night.”

The device, developed at the University of Maryland by Brantley Hall and colleagues, is the first wearable built specifically to measure human flatus.

One of Sheldon’s most unforgettable Halloween costumes wasn’t a superhero or a monster—it was the Doppler Effect. Was the costume scientifically accurate, and what exactly is the Doppler Effect anyway? In this episode, we’ll discover why every time an ambulance speeds past you, you’re actually hearing one of physics’ coolest phenomena.

One of Sheldon’s funniest one-liners is that multivitamins are nothing more than “expensive urine.” Is that just sitcom sarcasm, or is there real science behind the joke? In this episode, we dive into nutrition research, learn when vitamins actually help, and discover why the answer is much more interesting than a simple yes or no.

Sheldon proposes creating a night-light by inserting glowing jellyfish DNA into a fish—but is that science fiction or real genetic engineering? In this episode, we explore fluorescent proteins, genetically modified animals, and the surprising history of fish that really do glow. The science behind Sheldon’s strange idea helped transform biological research, although it probably would not illuminate your bedroom.

Did evolution really make women more sensitive to high-pitched sounds so they’ll wake up when a baby cries? In this episode, we separate a clever sitcom one-liner from decades of research in evolutionary psychology, neuroscience, and parenting. The answer is more fascinating—and much more nuanced—than the television version.

Could a stair that’s only two millimeters taller than the rest actually make someone fall? In this episode, we explore the surprising science of how your brain learns patterns while walking and why even tiny changes in stair height can throw off your stride. It’s a fun look at biomechanics, psychology, and engineering that proves reality is sometimes stranger than sitcoms.

Was Sheldon Right?, the podcast where we separate sitcom science from scientific fact.

Every autumn, Arctic ground squirrels do something no other mammal on Earth can survive: they let their bodies freeze. This episode unpacks the extraordinary physiology behind supercooling, from the molecular scaffolding that keeps ice crystals from forming in living tissue to the brain changes that make weeks of near-death possible. If you have ever wondered where biology ends and the genuinely miraculous begins, this is the episode.

You might think opting for a sugar-free soda saves your smile from destruction, but bizarrely, the dental truth is flipped completely on its head. This episode breaks down the strange science of chemical chelation, revealing how the extra citric acid hidden in diet drinks aggressively binds to the calcium in your mouth, stripping it away. Tune in to find out why a calorie-free fizzy drink can actually melt your protective enamel faster than its sugary counterpart.

Ball lightning manifests as luminous, spherical objects that appear during thunderstorms, floating unpredictably and defying conventional explanations of atmospheric electricity. Despite centuries of eyewitness reports and some instrumental recordings, scientists have yet to reach consensus on its formation or persistence. This episode explores historical accounts, leading scientific theories, and recent research illuminating one of nature’s most bizarre phenomena
