Since the manga's debut in 2017 and the subsequent release of the anime in 2019, Dr. Stone has been redefining classic shonen tropes by proving that brains are more powerful than brawn. The series follows high school savant Senku Ishigami in his uphill climb to revive modern technology after a mysterious global event caused all human beings to turn to stone.

After reviving 3,715 years in the future, Senku sets out to reinvent science from scratch. Along the way, the show explores many scientific techniques that range from the basic to the intensely complex. Needless to say, some explanations translate better than others.

10 Correct: Coriander & Lime Replicate Cola

Dr. Stone's Seku Cola.

In a gesture of appreciation as satisfying as it is sweet, Senku recreates classic cola for the modern mentalist, Gen Asagiri. Senku uses carbonated water, coriander, honey caramel, and lime to replicate Coca-Cola. Essentially, the lime and coriander carry most of the flavor, the honey caramel provides the signature dark color, and the carbonated water supplies the refreshing fizz.

Strain out the coriander pulp and voila, a homemade Coke. Since Coca-Cola was originally created as medicine, it's not a complete surprise that it shares a flavor profile with an ingredient that roughly 14% of people think tastes like soap.

9 Wrong: Scheelite Isn't Native To Japan

A major turning point near the end of Dr. Stone's first season is the discovery of scheelite. Morale was low in the Kingdom of Science after realizing that their copper tubing wouldn't be strong enough to withstand the heat needed to create a working cellphone.

Luckily, they find scheelite that can be used to make tungsten, the strongest natural metal on Earth. However, scheelite forms under very specific conditions, making it one of the rarest substances on the planet. It's much more likely that Senku's team would find wolframite, a quartz-based mineral that is well-known for its usage in forging tungsten and is actually native to Japan.

8 Correct: The North Star Moves

When it comes to science and math, Senku Ishigami is rarely wrong. After several millennia in stasis, however, it's not surprising that something managed to slip the genius's notice. Early on, Senku finds that his sextant's calculations are off. Since sextants use mirrors to create an angle between a celestial body and the horizon for navigational purposes, it's vital that the user use the proper celestial body to get the correct results.

Later, Senku realizes that he was off because the North Star that he was using as a guide had shifted over the last 3,715 years. This is because the North Star lies outside of the Earth's rotational axis, causing it to appear to arc over long periods of time. While it marks true North currently when Senku finally reawakens, the star Gamma Cephei will be positioned to be the new North Star.

7 Wrong: Kaseki Should Be A Jack Of All Trades & Master Of One

Kaseki from Dr. Stone.

It's a well-known statistic that it takes roughly 10,000 hours to be considered a master of any given skill. Therefore, it's fortunate for Senku and his love of science that Ishigami Village's resident artisan, Kaseki, has an uncanny ability to one-shot any art project he puts his hands on. As a natural craftsman, Kaseki feasibly put in the requisite time to learn to build impressive woodwork like the bridge leading to Ishigami Village and beautiful work like Kohaku's shield.

It is, however, highly unlikely that he'd have similar success crafting complex structures like engines and vacuum tubes, especially since these concepts were lost for thousands of years and his only direction comes from a teenager's drawings.

6 Correct: Their Modified Katanas Would Actually Work

After an attack from the Empire of Might, Senku decides to arm their own warriors with katanas to prepare for Tsukasa's next assault. Since time is short, Senku proposes that, during forgery, they fold the metal twice rather than the traditional 20 times.

It's true that in traditional Japanese swordsmithing, sword iron can be folded 10-20 times to make the strongest and most durable swords since repeatedly folding the heated metal removes impurities and evens out the sword's carbon content. Fortunately for The Kingdom of Science, two or three passes are sufficient for making a sturdy enough weapon.

5 Wrong: Thomas Edison Shouldn't Get Full Credit For Creating The Lightbulb

Many fans probably clocked this error when Senku credited Thomas Edison with the invention of the light bulb. In fact, Edison was just one of many inventors who experimented with incandescent lighting since the 1700s by heating metal filaments to such a high degree that they emit a consistent glow.

In reality, Thomas Edison can't even be credited with producing the first major usage of lightbulbs since British scientist Joseph Swan's lightbulbs powered the first fully electrified public building. Instead, Edison famously used marketing and exploited patent laws to bully his way to the forefront of electric innovation credit. However, as a caveat, Edison's one significant contribution to light bulbs was the invention of bamboo filaments, which Senku happened to use.

4 Correct: Records Can Be Made Out Of Glass Bottles

Senku finding his father's recording and uncovering the origins of Ishigami Village marked a huge milestone for The Kingdom of Science. As clever as his son, Byakuya Ishigami etched a record out of the bottom of a glass bottle to leave a message for his son to eventually uncover.

It might seem farfetched that a record can be made out of something that's not vinyl, but the concept has proven merit. Since records are created by channeling audio waves into grooves scratched into the vinyl, it's theoretically possible to create a record on any flat, carveable surface. Playable records have been made of wood, chocolate, and even ice.

3 Wrong: The Sulfa Drug Should've Dyed Ruri A Different Color

Much of Dr. Stone's first season is spent trying to formulate a cure for Kohaku's sister, Ruri. The team gathers supplies to create a sulfur-based medication called a sulfa drug that does, fortunately, succeed in healing Ruri. What the show misses, however, is the original drug's color.

In the show it's depicted as a white powder. However, certain chemicals in its formula come from synthetic dyes, giving it a deep reddish color. When the medicine's original creator used it to heal his own daughter's strep throat, it was strong enough to permanently dye her throat red.

2 Correct: Sulfa Drug Is Still An Effective Way To Fight Respiratory Infections

One of Senku's most important achievements is his successful recreation of a sulfur-based antibiotic called a sulfa drug. Since he chooses this approach because the natural bacteria used to make penicillin is so rare, it's widely considered that Senku is recreating the real-world pre-penicillin antibiotic, Prontosil.

Created in 1935, Prontosil is the first medicine to successfully combat bacterial infections. Since not much is clear about Ruri's illness other than respiratory distress, Senku takes a gamble and administers the drug, hoping it's not a chronic illness like tuberculosis. It's revealed that Ruri suffered from the world's longest case of pneumonia and the sulfa drug was successful. Even though it's been widely replaced by more readily available drugs like penicillin and amoxicillin, Prontosil is still used to treat particularly aggressive bacterial infections.

1 Wrong: Ishigami Village Couldn't Exist

One glaring incongruity that the show glosses over is the complete infeasibility that surrounds Ishigami Village. According to the show, Ishigami Village is descended from Seknu's father and five other astronauts who happened to be off-world at the time of the stoning event. Even considering the critical lack of genetic diversity doesn't kill them off within the first hundred years or so, it takes roughly 275 years to make ten generations.

Ishigami Villiage is about 133 generations removed from Senku's father. Think the span of time from Ancient Greece to now. It's both monumentally impressive and statistically improbable that Byakuya Ishigami's descendants could still be living in the same place, much less in a Stone Age capacity.
