Jacqueline Jenkins-Nye—Bill Nye's mother—worked as a code-breaker in World War II

The history and operation of SIGABA, the US counterpart of the Nazi Enigma machine

Developed by the US Army and US Navy, over 10,000 of these machines were deployed by the end of World War II to encrypt messages for the armed forces using three series of rotors. The device would continue to be used until the 1950s, while personal computers were shown to possess enough computing power to crack it by 2021.

The story of two female programmers running the simulations behind chaos theory's discovery

Margaret Hamilton and Ellen Fetter worked on MIT's 800-pound Royal McBee LGP-30 computer, which was fed binary code on paper tape to perform computations. Among the computations performed were those involving equations describing the motion of gas in a circulating fluid for Edward Lorenz, widely considered the father of chaos theory.

An NSA analyst helped avert nuclear war during the Cuban Missile Crisis

In October 1962, NSA cryptographer Juanita Moody headed analysis of U‑2 surveillance data and urgently produced intelligence on Soviet missile deployments in Cuba. Her reports drove high-level US decision-making, and were critical to avoiding nuclear war during the Cuban Missile Crisis.

A look at historical ciphers, from the Spartan 'scytale' to the Navajo Code Talkers

From the Greek word for "hidden writing," cryptography in Ancient Greece took the form of batons around which a long strip of leather or parchment was wrapped, after which messages were written. Recipients needed a scytale of the correct width to encircle received ribbons and reveal the message. Members of the Navajo Nation created a code that remained unbroken throughout its use in World War II.

Computer pioneer Alan Turing was also an elite runner

Alan Turing is credited with helping to found modern computer science, in addition to cracking the Nazi code known as Enigma. Beyond these world-historical achievements, the British mathematician also nearly represented his country in the Olympics in the marathon, running just 11 minutes slower than the eventual gold recipient at the 1948 games. Read more on this lesser-known aspect of the man here.

Ned Nye instilled an interest in timekeeping and sundials in Bill Nye

While a prisoner of war for four years during World War II, the Japanese military confiscated Ned's watch, so he built sundials to keep track of time. Ned would later research and write a book on sundials and be honored with a lifetime membership to the North American Sundial Society.

Marie Curie developed and trained women to operate mobile X-ray units in World War I

The “petites Curies” allowed medical professionals to identify the severity of wounds without transporting soldiers to medical facilities, expediting treatment and saving lives. The efforts of Curie and other women led to expansions in their rights after the war.

Grace Hopper described serving in the US Navy as the highest award she received

Despite retiring from the US Naval Reserve in 1966 at 60, as stipulated by Navy regulations, Hopper was repeatedly recalled for her pioneering expertise in computer science. By 1983, three years before her final retirement, she would give lectures about 200 days a year to computer scientists at military bases, college campuses, and businesses on behalf of the Navy.

US secrets: Project Paperclip

The US launched Project Paperclip in 1946, covertly recruiting over 1,500 German scientists to advance American military and space programs. Among them was Wernher von Braun, a key architect of the V-2 rocket who later became instrumental in NASA’s Apollo missions. While these scientists accelerated technological breakthroughs, their recruitment raised moral debates about overlooking wartime affiliations in the name of progress—questions that remain unresolved today.

Indigenous women crafted the integrated circuits for the Apollo Guidance Computer

Applying their blanket-weaving skills, over 1,000 Navajo women in New Mexico were hired to connect circuit components in intricate patterns using a microscope. Outside Boston, "rope mothers" at the Raytheon facility wove the AGC's core memory using threaded metal wires.

Can you save Britain from the Nazis by carefully sharing secrets with America?

Find out in this 20-minute interactive graphic novel based on true events from World War II.

The Night Witches

During World War II, one of the most effective Soviet bombing units flew wooden crop dusters that maxed out at 94 mph. They had no radios, no radar, and no parachutes. And the pilots? Young Soviet women, mostly in their teens and early twenties. The Germans called them Nachthexen—Night Witches. Shooting one down earned a Nazi soldier an Iron Cross, one of the highest military honors. However, for decades, most of the world forgot they existed. In this video, we trace how the Night Witches became one of the most feared units of WWII—and why their story nearly disappeared from history.

The woman erased from the DNA breakthrough

Rosalind Franklin captured “Photo 51,” the key to DNA’s double helix. Her data, shared without her knowledge, helped Watson and Crick win a Nobel. She never got the prize, but today, her role in unlocking life’s blueprint is finally recognized.

The Wright brothers' sister hyped their work, and was the only one to attend college

Watch Bill Nye be awarded the Presidential Medal of Freedom

President Joe Biden bestowed the honor for Nye's work in science education, science advocacy and environmental stewardship, with the White House adding, "By sharing the magic of fun and science, he inspires generations of Americans to follow facts and reason and leave the world better than we found it."

The Japanese Navy used radio silence and deception to mask its approach

In late November 1941, Japan’s carrier strike force maintained total radio silence while operators back home broadcast normal traffic—creating ambiguity about the location of the fleet. The deception obscured US intelligence and helped create a surprise attack.

Anne Frank's father, Otto, speaks to the BBC

The 13-year-old Jewish girl Anne Frank has inspired millions with her optimistic diaries amid Nazi oppression in the Netherlands. In 1976, her father—the sole survivor among Anne's immediate family—showed the world the original copy of one of Anne's three diaries in this BBC interview. Hear why Otto decided to publish the diaries and how that decision changed his life.

The origin of the National Science Foundation and why World War II led to its founding

Before World War II, research institutions were funded by endowments or private companies whose priorities stifled the curiosity-driven science that fueled significant breakthroughs and innovation. The NSF was established in 1950 to promote independent scientific progress through basic research, which is focused on knowledge acquisition rather than commercial applications, conducted at national colleges and universities.

The “Phoney War” was an eight‑month build-up to war

From September 1939 to May 1940, following their war declaration on Germany, Britain and France entered a phase of military inaction—even as civil defence measures, naval blockades, and rationing intensified at home. Skirmishes were limited, but the decisive fighting didn't begin until Germany invaded Norway and France in April–May 1940, abruptly ending the uneasy stalemate.

English mathematician Ada Lovelace wrote the first computer algorithm a century before computers existed and hypothesized that computing devices would one day be able to compose music—foreseeing the generative AI systems of today.

The food processing techniques developed for World War II, later repurposed for consumers

Research projects funded or sponsored by the military led to the development of active dry yeast to make bread easier to bake and an improved version of dehydrated cheese, which would be used in powdered cheese snacks. Freeze-drying, which had been used to ease the transport of blood plasma to battlefields, where it would be reconstituted with water, was later used on fruit for cereals.
