The terms 'bug' and 'debugging' were popularized by Grace Hopper's team

The first compiler to facilitate communication with computers was developed by Grace Hopper

The A-0 program linker automatically translated mathematical symbols into machine-readable binary code. Although it took two years for computer executives to get on board with the idea, the technology was foundational to future programming languages that allowed computers to understand commands written in word-based languages.

At the age of seven, Grace Hopper dismantled alarm clocks

Foreshadowing a career in computers, Hopper exhibited a curiosity for gadgets at a young age and took apart seven clocks, determined to understand how they worked. Despite having a dollhouse, Hopper built an elevator for it and showed a greater interest in building toy furniture than playing with dolls.

Bill Gates and Paul Allen were childhood friends before founding Microsoft

The two bonded over a teletype terminal at their school, which required a $40 hourly fee for computing time. They were banned from using the device after exploiting a bug that allowed them to bypass the fee, only to be later offered free computing time for finding more bugs.

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.

Dr. Seuss was likely the first to use the word 'nerd' in print

The word appeared in 1950's "If I Ran the Zoo," but there are theories that the word (or forms of it) were already part of popular slang before the book was published.

A dispute about the origin of twitching frog legs led to the invention of the first battery

Experiments by Luigi Galvani on exposed frog leg nerves showed activity when they were hung from iron railings and brass hooks, suggesting the existence of "animal electricity" that discharged when connected to metals. Alessandro Volta's voltaic pile, which stacked metals with an inorganic electrolyte, showed that electricity originates from chemical reactions.

A joke about mercury in an elevator led to the invention of emoticons

A false message about mercury contamination was posted in response to a physics problem on Carnegie Mellon's discussion board in 1982, which some users took seriously. The need to indicate which messages were jokes led to the creation of facial expressions using special characters.

Coined in 1971, the man credited with naming Silicon Valley was originally writing about semiconductors

Silicon Valley gained its name from an article published in January 1971, in Electronic News. Author Don Hoefler used the term in his headline for an article he was writing about the semiconductor industry. Hoefler is credited with naming the multi-trillion dollar area that is still called Silicon Valley today.

Credit for inventing the laser was fought over for nearly three decades

Although Theodore Maiman built the first working laser in 1960, Gordon Gould coined the term earlier. Charles Townes and Arthur Schawlow of Bell Labs filed a patent after Gould came up with the idea and name, but before Gould filed his patent.

Elk Cloner, the first computer virus to spread in public, was written as a practical joke by Richard Skrenta, a Pittsburgh high school student.

The virus was officially described for the first time in 1789

Michael Underwood, an English physician and surgeon, was the first to describe the disorder, noting it caused disability in the lower extremities in children. Large-scale outbreaks of the disease were not observed until the late 19th century.

The name 'Silicon Valley' arose from the founding of Shockley Semiconductor Laboratory in Fairchild Semiconductor in 1956-57, founded near Stanford University in Palo Alto

The software author was among several computer experts in 1988 who suggested that reports on the threat of computer viruses were exaggerated, referring to testimonials of infections and their spread as "urban legends."

The Year 2038 problem is the next potential computer time rollover bug

Many older systems store time as a signed 32-bit integer counting seconds since Jan. 1, 1970. That counter maxes out on Jan. 19, 2038—overflowing into negative time and sending clocks back to 1901, potentially crashing any older software that depends on accurate dates.

The word ‘hip-hop’ is often credited to DJ Lovebug Starski

The name was coined by Bronx DJ Lovebug Starski, who ad-libbed the term to match the rhythm of a beat while he was rapping. While it began as nonsense, the term went on to describe the music and multifaceted culture that surrounded it.

The history of many kitchen appliances involves unexpected discoveries and applications, including wartime radar turned hamster defroster and replacing an 'ice king' with heat-stealing boxes.

The 'butterfly effect' is the informal name for chaos theory

In mathematics, chaos theory involves complex systems that are highly sensitive to their initial conditions. Originally discovered when analyzing weather data, slight variations in the data input into such systems create drastically different results, despite following known physical laws.

Cookies were originally used as low-stakes ways to test the temperature of an oven

In 7th century Persia, bakers used small mounds of dough to test the heat in ovens before baking larger cakes. Afterward, they'd add honey, nuts, and other items to the small mounds, creating early cookies.

The typo that scandalized a continent

One printing mistake in the 17th century proved so unfortunate it cost two men their careers and scandalized religious folks for centuries. Read the story here.

Radioactive elements can introduce software errors because the ionizing radiation they produce can detach electrons from atoms, and computer code relies on the distribution of electrons.

How black boxes made flying safe

Black boxes—which are actually orange—were not universally present in airplanes until roughly 1967, a process which grew out of frustration over frequent, unexplained crashes in the industry's first few decades. This piece tells the origins of...

The first robot in literature may have been a 'mechanical man' in 1907's 'Ozma of Oz,' a book in L Frank Baum's 'Wizard of Oz' series.

Biologist Richard Dawkins coined the term 'meme'

His 1976 book "The Selfish Gene" proposed that units of culture could be replicated, passed on, and evolve as they were transmitted, similar to human genes. He called this unit a "meme," to be pronounced like "cream."

See a timeline of landmark discoveries in the field of genetics

From the first genetic map of fruit fly genes in 1911 through the completion of the Human Genome Project in 2003, scientists have built upon each other's discoveries to further our knowledge of the human body and the genetic instructions that inform our traits and disease risks.

A Monthy Python sketch inspired the internet term 'spam'

Although the canned meat product Spam has been around since 1937, it was a 1970 Monty Python comedy sketch—in which a diner is overwhelmed with unwanted Spam—that inspired early internet users to call unsolicited emails "spam."

The term 'burnout' in academia dates back to 1974

Psychologist Herbert Freudenberger introduced the term to describe the mental and emotional fatigue he witnessed among volunteers at a free clinic in New York. It was widely popularized in a 1976 article by Berkeley professor Christina Maslach.

Henry Ford pioneered the first moving assembly line, building on earlier iterations of the manufacturing method

Although cars existed before the Model T, manufacturing them required a group of highly specialized mechanics. The Model T was so affordable in large part because of the moving assembly line, which cut down the total manufacturing time of the car and replaced specialized workers with general laborers who performed repetitive tasks.

Biohacking: The effort to optimize health and extend life through technology

Biohacking seeks to optimize human health and performance through everything from simple lifestyle adjustments to more radical interventions like body modifications and experimental technology. At its core, biohacking covers a wide spectrum—ranging from improving sleep and focus to implanting devices that integrate technology with the human body.
