In celebration of Futurama returning with a fresh season, we’ve rounded up 10 clever scientific references that pepper the series. The show’s writers boast PhDs in physics, mathematics, computer science, and other brain‑tasting fields, sprinkling jokes that only those steeped in the subject matter truly appreciate. With this guide, you’ll catch the hidden science, learn a bit, and enjoy a chuckle.

10. The Salmon Life Cycle

Season 7’s episode “Naturama” (Episode 13) treats viewers to a three‑part nature documentary titled “Mutuals of Omicron’s Wild Universe.” While Futurama usually dives into mind‑bending quantum quirks, this installment pauses to showcase ecological wonders such as the salmon life cycle, tortoise courtship, and elephant‑seal social hierarchies. Though less cerebral than many other episodes, “Naturama” would have saved me from flunking my sixth‑grade biology quiz.

“Part 1: The Salmon” opens on a chilly freshwater stream where salmon eggs hatch amid gravel. The animation introduces the first two developmental stages: the alevin—tiny fish still attached to a yolk sac—and, after consuming the yolk, the fry, which, like Fry the character, embarks on a journey from river to sea.

Soon Fry meets a gorgeous fish named Leela, who promises to pair up when they reach breeding age. After a series of underwater dates, Fry, Leela, and their generation mature, begin their upstream trek, and discover—much to their dismay—that they hail from neighboring streams. A heroic bear intervenes, reuniting the pair. Leela spawns her eggs, Fry fertilizes them, and the two meet a tragic end together. While real salmon don’t fall in love or arrange cute dates, Futurama’s portrayal captures the essential steps of the salmon life cycle with entertaining flair.

9. Delta Brain Waves

In the classic “Roswell That End’s Well,” the crew travels back to 1947 New Mexico, and a series of ill‑judged decisions leads Fry to become his own grandfather. This bizarre lineage wipes out his delta brain‑wave pattern, granting him a unique neural signature that makes him immune to several mind‑hacking threats.

For instance, the “Into the Wild Green Yonder” episode introduces the Dark Ones—a telepathic species bent on universal domination. Because Fry lacks delta waves, the Dark Ones can’t pry into his thoughts, allowing him to keep his secrets and save the cosmos undetected.

Initially, I assumed delta brain‑waves were a Futurama invention, but they’re genuinely the slowest human brainwave, linked to deep sleep and restorative relaxation. Delta waves influence subconscious processing, making them attractive targets for brain‑hacking. Moreover, research hints at a negative correlation between delta activity and spiritual intelligence, suggesting Fry’s unusual brain pattern could make him especially adept at resisting the series’ peculiar dark forces.

8. BASIC

BASIC—short for Beginner’s All‑purpose Symbolic Instruction Code—is a programming language crafted in 1964 by John G. Kemeny and Thomas E. Kurtz to teach novices the fundamentals of coding. In the episode “I, Robot,” the language’s longevity is highlighted when Fry, moving in with Bender, spots a sign that reads “10 HOME, 20 SWEET, 30 GO TO 10,” a classic BASIC loop that translates to “Home Sweet Home” for those unfamiliar with the syntax.

7. The Birth Of Our Universe

Season 6’s “The Late Phillip J Fry” offers a dazzling tour of cosmology. While rushing to meet Leela for dinner, Fry convinces Professor Farnsworth to test a forward‑time device. After a mishap sends them careening through spacetime, they end up in the year 10 000 AD. Continuing forward, they watch the universe wind down to a cold void, only to witness a cataclysmic explosion that Farnsworth identifies as the Big Bang.

The sequence beautifully visualizes the birth of the cosmos: gravity pulls matter into the first stars and galaxies, swirling dust and gas coalesce into Earth, and a colossal impact—known as the moon‑forming impact—splits a proto‑Earth, creating our lunar companion. The crew observes early evolution, the arrival of the first colonizers, and major milestones in natural and human history before finally returning home.

6. The Problem Of Relativity

Futurama’s intergalactic shenanigans routinely feature faster‑than‑light travel, a plot device that bends Einstein’s special relativity. Rather than an oversight, writers David Cohen and Matt Groening deliberately chose entertainment over strict physics, as Cohen explained in an American Physical Society interview: they aim to amuse scientists even if the science is “bogus.”

This self‑awareness appears in “A Clone of My Own,” where Professor Farnsworth boasts of “dark‑matter engines… traveling between galaxies in mere hours.” When his clone Cubert points out the impossibility of surpassing light speed, Farnsworth replies that “scientists increased the speed of light in 2208.” By simply redefining the constant c, the show sidesteps the infinite‑mass problem of approaching light speed, allowing characters to zip across space without violating physics.

5. Heisenberg’s Uncertainty Principle

In “Luck of the Fryrish” (Season 3, Episode 4), Professor Farnsworth laments a loss at the racetrack, invoking the observer effect. Werner Heisenberg’s 1927 principle states that one cannot simultaneously know a particle’s exact position and momentum. Because particles exhibit wave‑like behavior, measuring one property inevitably disturbs the other.

Farnsworth’s bet on a dead‑heat between two horses ends with judges using an electron microscope to declare a winner. He protests, “No fair! You changed the outcome by measuring it,” highlighting that the act of measurement collapses the wavefunction, altering the system—a direct nod to the Uncertainty Principle’s core insight.

4. Schrodinger’s Cat

Erwin Schrödinger’s famous thought experiment from 1935 illustrates superposition: a cat sealed in a box with a 50/50 chance of lethal poison remains simultaneously alive and dead until observed. Futurama references this in “Law and Oracle” (Season 6, Episode 16), where a frantic Schrödinger speeds away from Officer Fry and partner URL.

When captured, Schrödinger explains his mysterious box contains “a cat, some poison, und a cesium atom.” Fry demands to know the cat’s fate; Schrödinger replies that it exists in a superposition of both states until opened, collapsing the wavefunction. Fry opens the box, only to be assaulted by a very much alive cat, confirming the superposition resolved into life.

3. Möbius Strip

Recall the high‑school activity of giving a strip of paper a half‑twist and taping the ends together? That creates a Möbius strip—a non‑orientable surface with only one side. Futurama toys with this concept in the episode “Möbius Dick” (6ACV15), where the crew encounters a four‑dimensional space whale that Leela dubs Möbius Dick—a clever pun on Herman Melville’s novel.

The strip reappears in “2‑D Blacktop” (7ACV15), where Leela and Professor Farnsworth race along a Möbius‑shaped dragstrip. Their vehicles loop around both sides of the half‑twist, collide at relativistic speeds, and get thrust into a two‑dimensional universe—only to return safely to three dimensions later.

2. The Banach‑Tarski Paradox

“Benderama” showcases Professor Farnsworth’s “Banach‑Tarski Dupla‑Shrinker,” a nod to the Banach‑Tarski paradox, which proves that a solid sphere can be dissected into a finite number of pieces and reassembled into two identical copies of the original—essentially infinite cloning. While the mathematics involve manipulating countably and uncountably infinite sets, the episode sidesteps deep proofs.

Farnsworth, an aging inventor, creates a device to shrink his sweaters. Bender, refusing to fold them, implants the machine in his chest, spawning two 60%‑sized Bender clones. Each clone repeats the process, leading to an infinite cascade of Benders that eventually unite to defeat a giant, forming a massive composite Bender. Though the show bends the paradox, it cleverly references the mind‑boggling theorem.

1. The Futurama Theorem

Ken Keeler, a Harvard‑trained applied mathematician, authored the episode “The Prisoner of Benda” (7ACV10) and created the only mathematical proof written exclusively for television. The Futurama Theorem states that any permutation of n objects can be restored using a sequence of non‑repeating swaps, requiring no more than two extra objects.

In the episode, Farnsworth and Amy use a “mind‑switcher” that prevents the same pair from swapping twice. Chaos ensues as multiple characters, even wash buckets, become entangled. By introducing two helpers—Bubblegum and Sweet Clyde—the crew systematically swaps minds back to their rightful bodies, following a step‑by‑step algorithm that demonstrates the theorem’s power.

Group 1 proceeds: B(P) SC(SC), BG(BG) P(L), and so on, ultimately restoring everyone. Group 2 uses the same helpers to resolve the Fry‑Zoidberg swap. The theorem’s elegance shines as the episode wraps up with every character back in place, proving that even the most tangled mind‑mix‑ups have a mathematical solution.

With the 2020 Netflix remake of Alfred Hitchcock’s classic Rebecca, it’s crystal‑clear that the master’s influence still reverberates across pop culture. Even four decades after his passing, Hitchcock’s daring storytelling continues to shape movies, television, music and more. Below, we count down 10 memorable hitchcock references that keep his legacy thriving.

10 memorable hitchcock Tributes Across Media

10 Scream: “We All Go a Little Mad Sometimes”

Wes Craven’s 1990s slasher sensation loves to wink at its horror‑movie ancestors, and a particularly sharp nod lands squarely on Hitchcock’s Psycho. When the self‑aware killer Billy Loomis declares, “We all go a little mad sometimes,” he’s echoing the unsettling line spoken by Norman Bates at the climax of the 1960 classic. Even the surname Loomis isn’t a coincidence—it matches the husband of Marion Crane, the unfortunate first victim in Hitchcock’s tale, hinting that Billy may have taken his murderous inspiration straight from Bates.

The dialogue isn’t the only Easter egg: Billy’s obsession with horror cinema mirrors the meta‑commentary that Craven builds throughout the film, positioning Scream as both a tribute and a fresh take on the genre that Hitchcock helped define.

9 Family Guy: “North By North Quahog”

Season three’s opener of Family Guy shouts homage from the rooftops with a title that screams North by Northwest. Peter Griffin’s misadventure—stealing a script from a hotel, then being chased by a crop‑duster plane—mirrors the iconic aerial chase from Hitchcock’s 1959 thriller. The animated series even recreates the Mount Rushmore climax, swapping the famous statue for a hilariously oversize version of Mel Gibson’s house.

Creator Seth MacFarlane’s own love affair with Hitchcock shines through, especially when you recall his 2013 Oscar promo that spoofed Psycho. The episode proves that the cartoon can pull off a shot‑for‑shot tribute while still delivering its signature brand of irreverent humor.

8 Horrible Bosses: Strangers on a Train

The premise of Horrible Bosses feels ripped straight from Hitchcock’s Strangers on a Train. When three disgruntled employees meet a “murder consultant” who suggests swapping murders to secure perfect alibis, the plot directly riffs on the infamous train‑swap theory. Jason Bateman’s character even points out the similarity, noting that the scheme mirrors the classic Hitchcock narrative.

Adding a meta‑twist, Charlie Day’s character references the parody film Throw Momma from the Train, which itself lampoons Hitchcock’s original. The self‑aware dialogue underscores how the modern comedy leans on the suspense master’s blueprint while delivering its own brand of chaos.

7 The (Not So Great) Hitchcock Remakes

Directors have long tried to recast Hitchcock’s masterpieces, but few have succeeded. The 2020 Netflix version of Rebecca earned a lukewarm 41 % on Rotten Tomatoes, with critics lamenting its lack of fresh insight. Even the 1998 shot‑for‑shot remake of Psycho starring Vince Vaughn is often forgotten, as if it never happened.

Conversely, Mel Brooks’s parody High Anxiety stands out as a brilliant homage, playfully riffing on Vertigo, Spellbound and Psycho. The consensus? Only reinterpretations that add genuine wit or new perspective deserve the Hitchcock mantle.

6 That ’70s Show: Hitchcock Halloween Episode

The fourth episode of season three, “Too Old to Trick or Treat, Too Young to Die,” is a love letter to the master’s oeuvre. Fez, confined to a wheelchair after a broken leg, channels James Stewart’s role in Rear Window, spying on a neighbor he suspects of murder through a pair of binoculars.

The episode also riffs on The Birds when Kitty struggles with a flock of ominous avians, nods to Vertigo as Eric develops a fear of heights, and even reenacts the infamous shower scene from Psycho. A final gag mirrors the crop‑duster chase from North by Northwest, wrapping the homage in pure sitcom fun.

5 The Simpsons: Treehouse of Horror Hitchcock Spoof

When it comes to cinematic shout‑outs, The Simpsons is a gold mine. Over the years the animated series has lampooned virtually every Hitchcock classic—Vertigo, Psycho, Strangers on a Train, North by Northwest, The Birds and Rear Window—often layering multiple references into a single gag.

One standout is the Treehouse of Horror XX special, which packs at least five distinct Hitchcock nods, including a silhouette of Homer echoing the master’s TV series Alfred Hitchcock Presents. The episode even features Hitchcock’s trademark cameo, a subtle reminder that the director appeared in over 38 of his own films.

4 Bates Motel: Norman Bates Origin Story

The A&E series Bates Motel offers a deep dive into the psyche of Norman Bates, the iconic villain of Psycho. Premiering more than half a century after the original film, the show expands the legend, even scoring a cameo by Rihanna as Marion Crane.

Beyond recreating the infamous shower scene—with a modern twist—the series explores the twisted mother‑son dynamic that fuels Norman’s darkness. Starting with a relatively normal teen, the narrative charts his descent into the infamous “psycho” persona that still haunts pop culture.

3 Psycho Shower Scene: The Spoofs

The 1960 shower sequence is arguably cinema’s most recognizable moment: a shadowed curtain, a knife inching closer, and Bernard Herrmann’s screeching strings. Its shock value sparked controversy at the time and cemented its place in film history.

Decades later, the scene has been parodied endlessly—from Looney Tunes cartoons to Mel Brooks’s High Anxiety, and even in the modern reinterpretation on Bates Motel. Even Jamie Lee Curtis, daughter of the actress who played Marion Crane, has reenacted the iconic moment, proving its timeless appeal.

2 The Beatles: “Eleanor Rigby” Inspired by Psycho Score

Surprisingly, the haunting strings that drive the Beatles’ “Eleanor Rigby” trace their inspiration back to Hitchcock’s Psycho score. Producer George Martin revealed that when Paul McCartney suggested a string arrangement, he turned to the screeching, tension‑filled motifs that Bernard Herrmann crafted for the film.

The result is a darker, more somber melody that mirrors the unsettling atmosphere of the classic thriller. While the song’s lyrics tell a different story, the musical undercurrent unmistakably channels Hitchcock’s chilling soundscape.

1 James Bond: North by Northwest Influence on Bond Franchise

It may come as a surprise, but Hitchcock’s North by Northwest laid the groundwork for the entire James Bond saga. Ian Fleming even wanted Cary Grant—fresh from his suave performance in Hitchcock’s spy thriller—to embody 007, though Grant ultimately declined.

The film’s formula—slick espionage, glamorous locales, a dashing hero chased by relentless foes—mirrored the DNA of every Bond installment that followed. From the soaring vistas to the charismatic, danger‑dodging protagonist, the influence is unmistakable, cementing Hitchcock’s indirect but vital role in shaping the world’s most famous secret agent.
