10 Explosive Facts About the Trinity Nuclear Test

“Now I am become death, the destroyer of worlds.”

That line, paraphrased from the Hindu Bhagavad Gita, crossed Robert Oppenheimer’s mind as he became a witness to history. On July 16, 1945, at 5:29:45 AM (MT), the first atomic bomb ever detonated went off near Socorro, New Mexico. Seventy years later, we’re still feeling the political and scientific shockwaves of this high-stakes experiment.   

1. Eight Different Sites Were Considered.

U.S. military officials started looking for a suitable location in May 1944. The barrier sand reefs over by south Texas were assessed, as was an island off California’s southern coast and Rice, California (now a ghost town). Colorado's San Luis Valley region was also under consideration. 

New Mexico alone presented four separate options: the Tularosa basin, an expanse near Cuba, the deserts south of Grants, and—finally— a parched, 90-mile stretch called “Jornada del Muerto,” or “route of the dead men.” After much discussion, the latter spot was chosen. As a remote locale with an abundance of wide open space, it offered many pluses. What's more, it wasn’t far from Los Alamos, where the Manhattan Project’s bombs were under development. Base camp construction started that fall.

2. Nobody Knows Where the Code Name “Trinity” Came From.

Oppenheimer took the credit, but forgot all about his own source of inspiration. “Why I chose this name is not clear,” he admitted in a 1962 conversation with General Leslie Groves. Still, the well-read physicist did hazard some guesses. As the fateful day approached, Oppenheimer often thought of John Donne, a 17th-century poet whom he greatly admired. Invoking Christianity’s Holy Trinity, Donne began one famous sonnet with “Batter my heart, three person’d God.” But, confessed Oppenheimer, “Beyond this, I have no clues whatsoever.”

3. There Was a Rehearsal.

108 tons of TNT were placed atop a twenty-foot wooden platform and blown up on May 7, 1945. Among other things, the helpful run-through allowed everyone to calibrate their data collection equipment.     

4. Edward Teller Feared That the Test Might Ignite Earth’s Atmosphere.

Work came to a grinding halt (at least by some accounts) when this “father of the hydrogen bomb” presented his doomsday scenario. Fission explosions, like the one America’s first nuke would create, produce unbelievable heat—think tens of millions of degrees Fahrenheit. Teller feared that this’d be hot enough to fuse nitrogen atoms throughout our planet’s atmosphere, kicking off a catastrophic release of energy. Without warning, the whole human race might be incinerated. Obviously, this was no minor concern. 

Common sense demanded an investigation. “Better to accept the slavery of the Nazis than to run a chance of drawing a final curtain on mankind,” Nobel laureate Arthur Compton would later say. Luckily, further analysis disproved Teller’s nightmarish theory. 

5. The Team Ran a Betting Pool on How Big Their Explosion Would Be.

Teller wagered that it would equal 45,000 tons’ worth of TNT.  Hans Bethe went with 8,000 tons. For his part, Oppenheimer not only chose a meager 300 tons but privately bet another associate $10 that the whole test would be an abject failure. In contrast, General Groves started getting annoyed when Enrico Fermi “offered to take wagers from his fellow scientists on whether or not the bomb would … merely destroy New Mexico or the entire world.”   

6. The Fireball Was Seen as Far as 180 Miles Away.     

Upon going off, the finished product wielded enough force to match around 20,000 tons of TNT. It also let loose a radiant burst of light which startled witnesses in Albuquerque, Santa Fe, Silver City, and El Paso. 

One Rowena Baca of San Antonio, NM, only 35 miles away, suddenly found herself being shoved under a bed by her grandmother, who mistook Trinity’s handiwork for “the end of the world.” And while flying out near Albuquerque that morning, Navy pilot John R. Lugo initially thought he was watching the sun rise—from the south.

7. At First, Civilians Were Told that It Was a Simple Military Blunder.

The armed forces appeared to clear things up by releasing this statement (a carefully-written cover story), which ran in New Mexican papers hours after the fact:     

Several inquiries have been received concerning a heavy explosion which occurred on the Alamogordo Army Air Base reservation this morning. A remotely located ammunition magazine containing a considerable amount of high explosive and pyrotechnics exploded. There was no loss of life or injury to anyone, and the property damage outside of the explosives magazine itself was negligible. Weather conditions affecting the content of gas shells exploded by the blast may make it desirable for the Army to evacuate temporarily a few civilians from their homes. 

Ordinary Americans would be kept in the dark about what had really happened until after the Japanese bombings.  

8. The Trinity Bomb Used the Same Design as the One That Was Dropped on Nagasaki 24 Days Later.

Whereas a uranium-based weapon (nicknamed “Little Boy”) laid Hiroshima low, Nagasaki’s bomb (a.k.a.: “Fat Man”) relied on plutonium. The former was fairly simple and the scientists were confident it didn’t need testing, but the latter was more complicated, requiring that a core filled with this dangerous element implode before it could explode. 

9. “Trinitite” is a Glassy Substance Created in the Historic Blast.

Bits of southwestern sand were transformed by the unnatural heat, reborn as a peculiar glass-like material. Today, one can’t legally go out in the field and gather trinitite, which—by the way—is radioactive, though it becomes less so over time.  

10. You Can Visit a House that Survived the Whole Ordeal.

Most of the windows were shattered, some roofing flew off, and the roof itself bowed inward. But otherwise, the George McDonald ranch house remained more or less intact, despite standing only two miles away from Trinity’s ground zero. "Abandoned" by its original owners in 1942 (although they did stage a high profile armed occupation of the area in 1982), Manhattan Project personnel repurposed the building’s bedroom as a bomb assembly zone. Since then, it’s been renovated and nuclear tourists are allowed to drop by on select days.

Would You Be Able to Pass a World War I Military Literacy Test?

Though reading and writing might not come to mind as the first requirement for trench warfare, during the early 20th century, the U.S. Army became increasingly concerned with whether or not its soldiers were literate. Thousands of World War I soldiers couldn't read printed directions on basic military tasks. The Army didn't implement its first major literacy program until the 1940s, but literacy tests were included in a battery of psychological evaluations World War I recruits went through to determine their mental fitness and intelligence, as the blog Futility Closet recently highlighted.

These unconventional literacy tests largely took the form of a yes or no questions with obvious answers, according to the 1921 report from the U.S. Surgeon General, Psychological Examining in the United States Army. Edited by pioneering intelligence-testing psychologist Robert Yerkes, who developed the military's first psychology exams for new recruits (and was also famous for his support for eugenics), the volume is a lengthy compilation of all of the methods the U.S. Army used to test the intelligence of its future soldiers. Many of these tests are now considered racist and culturally biased—some of the "intelligence" testing questions required recruits to know things like what products Velvet Joe (a figure used in tobacco campaigns) advertised—but some of the literacy questions, in particular, simply come off as weird in the modern era. Some are downright existential, in fact, while others—"Is a guitar a disease?"—come off as almost poetic.

One test, the Devens Literarcy Test, asked recruits questions like "Is genuine happiness a priceless treasure?" and "Does success tend to bring pleasure?" Another section of the test asked "Do boys like to play?" and "Do clerks enjoy a vacation?"

Other questions seem like they're up for debate, like "Are painters ever artless individuals?" and "Is extremely athletic exercise surely necessary?" Surely the answers to questions like "Should criminals forfeit liberty?" and "Is misuse of money an evil?" depend on the opinions of the reader. The answer to "Do imbeciles usually hold responsible offices?" might be different depending on how the person feels about their Congressional representative, and could surely be the spark for an hour-long argument at most dinner parties.

Still others are tests of cultural knowledge, not reading skill—a major modern criticism of Yerkes's work. Despite being arguably a pretty literate person, I certainly don't know the answer to the question "Do voluntary enlistments increase the army?" A question like "Are 'diminutive' and 'Lilliputian' nearly identical?" isn't exactly a test of literacy, but a test of whether or not you've read Gulliver's Travels, which doesn't exactly seem like a necessity for military success.

Luckily, some of the questions are pretty obvious, like "Is coal white?" That one I can answer. The full list of questions used in the various versions of the Devens test is below for you to test your own Army-level literacy.

10 Not-So-Small Facts About the Volkswagen Beetle

While Volkswagen has announced—for a second time—that it's going to cease production on the Beetle, people are still singing the praises of the quirky little car. Here are 10 not-so-small things you need to know about the German car that was once named one of the top four cars of the century.


Adolf Hitler checks out a VW Beetle

It’s long been said that Adolf Hitler was the man behind the Beetle, and that’s sort of true. The dictator wanted German families to be able to afford a car, so he enlisted automaker Ferdinand Porsche (yes, that Porsche) to make “the people’s car.” But the basis for the Beetle had been around since long before Hitler’s demand; the Bug was heavily influenced by Porsche's V series. Rumors that Hitler directly designed the car are probably false; though he was the one who reportedly said that the car should look like a beetle, because “You only have to observe nature to learn how best to achieve streamlining,” it’s likely that he was regurgitating something he had read in an automotive magazine. Still, one thing is for certain: Hitler himself placed the cornerstone for the Porsche factory in Wolfsburg, Germany.


Perhaps still wary of anything imported from Germany, Americans shunned the Beetle when it was introduced in the States in 1949: Only two were sold in the first year. But after that, sales grew quickly. By the 1960s, hundreds of thousands of Bugs were sold every year, topping out at 570,000 in 1970.


A pink VW Beetle

We have the public to thank for the car’s distinctive nickname. Originally known as the Volkswagen Type 1, the car’s curves and rounded top led to its later, insect-like moniker. Volkswagen must have realized they had a good thing on their hands, because they started referring to the car as the VW Beetle in the late 1960s.


The UK and the U.S. aren’t the only countries that bestowed a new name on the Volkswagen Type 1. In France, it's called Coccinellewhich means ladybug. It's Maggiolino and Fusca in Italy and Brazil, respectively, both of which mean "beetle." Mexico calls it Vocho; it's Peta (turtle) in Bolivia; and Kodok (frog) in Indonesia. 


In 1999, Advertising Age declared the car's not-so-small ad campaign to be the best campaign of the last 100 years, besting Coca-Cola, Marlboro, Nike, and McDonald’s. The quirky concept and copy—which, according to Advertising Age, “Gave advertising permission to surprise, to defy and to engage the consumer without bludgeoning him about the face and body”—was a game-changer for the entire industry.

The "Think Small" line and accompanying self-deprecating copy was written by Julian Koenig, who was also responsible for naming Earth Day and coming up with Timex’s “It takes a licking and keeps on ticking” tagline. He’s also half-responsible for daughter Sarah Koenig, whom you may know from NPR’s This American Life and Serial.


Herbie the Love Bug

Because of their distinctive aesthetic, VW Bugs have been associated with everything from the Beatles to Transformers. A few highlights:

  • The Beetle with the license plate “LMW 28IF” on the cover of The Beatles' Abbey Road album was sold at an auction for $23,000 in 1986. It is now on display at Volkswagen's AutoMuseum at the company’s headquarters in Wolfsburg, Germany.
  • The Fremont Troll sculpture in Seattle, a huge statue lurking under the Aurora Bridge, clutches an actual VW Beetle. An in-progress picture shows that the car was once red. It also once contained a time capsule of Elvis memorabilia, which was stolen.
  • The Herbie the Love Bug series was a big hit for Disney in the late 1960s and early 1970s. One of the original Herbies sold for $126,500 at an auction in 2015.
  • In the original Transformers cartoon, Bumblebee transformed from a VW Bug. The car was changed to a Camaro for the live-action movies.


The so-called “blumenvasen,” a small vase that could be clipped to the dashboard, speaker grille, or windshield, was porcelain when it was originally offered. The nod to flower power became such a symbol of the car that it was incorporated into the 1998 redesign. Sadly, it didn’t make the cut for the most recent overhaul: The vase was eliminated in 2011 by marketing execs apparently seeking to make the car more male-friendly.


When the millionth VW Beetle rolled off the line in 1955, the company capped the achievement by plating the car in gold and giving it diamante accents. They also created a Bug with a wicker body in collaboration with master basket-maker Thomas Heinrich.


After WWII, the VW factory in Wolfsburg, Germany, was supposed to be handed over to the British. No British car manufacturer wanted to take responsibility for the company, though, saying that "the vehicle does not meet the fundamental technical requirement of a motor-car," "it is quite unattractive to the average buyer," and that "To build the car commercially would be a completely uneconomic enterprise." Whoops.
