Our Heritage of Technology

On June 5, 1833, Ada Byron met Charles Babbage at a party in London and walked away captivated by his mechanical Difference Engine.

On this date in 1961 – Project Mercury: Alan Shepard becomes the first American to travel into outer space, on a sub-orbital flight.

Mercury-Redstone 3, or Freedom 7, was the first United States human spaceflight, on May 5, 1961, piloted by astronaut Alan Shepard. It was the first crewed flight of Project Mercury. The project had the ultimate objective of putting an astronaut into orbit around the Earth and returning him safely. Shepard's mission was a 15-minute suborbital flight with the primary objective of demonstrating his ability to withstand the high g-forces of launch and atmospheric re-entry.

Shepard named his space capsule Freedom 7, setting a precedent for the remaining six Mercury astronauts naming their spacecraft and the format of their names. They selected names ending with a "7" in all the crewed Mercury spacecraft to commemorate the NASA's first group of seven astronauts. the number 7 also was the model number for the McDonnell Model #7 space capsule used in the Mercury Program. His spacecraft reached an altitude of 101.2 nautical miles (116.5 statute miles, 187.5 km) and traveled a downrange distance of 263.1 nautical miles (302.8 statute miles, 487.3 km). It was the fourth Mercury flight launched with the Mercury-Redstone Launch Vehicle, from Cape Canaveral, Florida, close to the Atlantic Ocean.

During the flight, Shepard observed the Earth and tested the capsule's attitude control system, turning the capsule around to face its blunt heat shield forward for atmospheric re-entry. He also tested the retrorockets which would return later missions from orbit, though the capsule did not have enough energy to remain in orbit. After re-entry, the capsule landed by parachute on the North Atlantic Ocean off the Bahamas. Shepard and the capsule were picked up by helicopter and brought to U.S. Navy aircraft carrier USS Lake Champlain.

On April 30, 1993, CERN issued an official document that put the World Wide Web software and protocols into the public domain.

NASA's Artemis II Crew Launches To The Moon (Official Broadcast)

We're sending astronauts around the Moon for the first time in 50 years. Come watch with us. NASA's Artemis II mission is scheduled to lift off from Kennedy Space Center on April 1. The two-hour launch window starts at 6:24 p.m. EDT (2224 UTC). Four astronauts — three from NASA and one from the CSA (Canadian Space Agency) — make up the Artemis II crew:

NASA astronaut Reid Wiseman, Artemis II commander

NASA astronaut Victor Glover, Artemis II pilot

NASA astronaut Christina Koch, Artemis II mission specialist

Canadian Space Agency (CSA) astronaut Jeremy Hansen, Artemis II mission specialist

PLATO (Programmed Logic for Automatic Teaching Operations) was a groundbreaking computer-based education system that began in 1960 on the ILLIAC I mainframe. Its true strength was not a single machine, but a network of interconnected mainframes and terminals. By the late 1970s, PLATO supported thousands of graphical terminals worldwide, with multi-user capabilities far ahead of its time.

The most notable hardware was the PLATO IV terminal. It featured a 512×512 plasma display capable of showing both text and vector graphics at high speed (about 60 lines or 180 characters per second at 1260 baud). The display had built-in memory and was paired with a 16×16 infrared touchscreen, allowing users to interact directly—an early precursor to modern touch interfaces.

The terminal also included advanced multimedia features. An audio unit could store up to 4096 sound clips (around 17–22 minutes total) and retrieve them within 0.4 seconds. It also supported a Votrax speech synthesizer and the Gooch Synthetic Woodwind, a 4-voice (later 16-voice) music synthesizer. For color images, a microfiche projection system displayed images behind the screen.

The terminals themselves had minimal processing power; all computation was handled by central mainframes. Through networking, hundreds to thousands of users could work simultaneously.

On February 4, 2004, a website originally designed for Harvard University students quietly launched under the name TheFacebook. Created by Mark Zuckerberg and a small group of collaborators, the platform would soon evolve into Facebook, fundamentally transforming communication and social interaction worldwide.

Initially limited to college campuses, Facebook allowed users to create personal profiles, connect with friends, and share updates online. Its real-name policy and clean design distinguished it from earlier social networking sites, fostering a sense of authenticity and trust among users.

As access expanded beyond universities, Facebook’s user base grew exponentially. The platform became a central hub for social interaction, news sharing, event organization, and digital advertising. Businesses, political campaigns, and media outlets quickly recognized its influence, using it to reach targeted audiences on an unprecedented scale.

Facebook’s growth also sparked complex debates about privacy, data usage, and the role of social media in shaping public opinion. The platform has been linked to both positive movements, such as grassroots activism, and negative consequences, including misinformation and online polarization.

Despite ongoing scrutiny and competition from newer platforms, Facebook remains one of the most influential digital entities in history. Its launch on February 4 represents a pivotal moment in the evolution of the internet, signaling the beginning of the social media era.
