Apple Introduces Revolutionary Macintosh Computer

Personal computing in the early 1980s remained largely command-line driven and intimidating for average users, with Apple seeking to differentiate its products through intuitive design under Steve Jobs's vision. On January 24, 1984, Apple launched the Macintosh, featuring a graphical user interface, mouse, and 9-inch screen in a compact all-in-one unit priced accessibly. The launch followed the iconic "1984" Super Bowl commercial that positioned the machine against corporate conformity. Early sales were strong despite limited software and storage, demonstrating demand for user-friendly technology. The Macintosh established key standards for desktop interfaces that competitors later adopted. It marked a turning point in making computers tools for creative and everyday work rather than specialists alone.

Bruce McCandless Performs First Untethered Spacewalk

NASA's Space Shuttle program advanced human spaceflight capabilities with new mobility systems for astronauts. During the STS-41-B mission aboard Challenger, engineers tested the Manned Maneuvering Unit, a nitrogen-propelled backpack. On February 7, 1984, astronaut Bruce McCandless II exited the shuttle and flew freely without a tether, becoming the first human to do so. He maneuvered up to 300 feet from the orbiter using hand controls while colleague Robert Stewart followed. The test validated the unit's performance in orbit at 170 miles altitude. McCandless's solo flight demonstrated unprecedented astronaut independence during extravehicular activity.

Alexey Pajitnov Releases Tetris in the Soviet Union

While working at the Dorodnitsyn Computing Center in Moscow, Soviet programmer Alexey Pajitnov developed a puzzle game inspired by pentomino tiling problems. He completed the first version of Tetris on an Elektronika 60 computer and made it available to colleagues on June 6, 1984. The game spread rapidly through Soviet institutions and was soon ported to other platforms. Its simple mechanics of rotating falling tetrominoes to complete lines proved instantly addictive. Tetris later achieved global popularity after licensing deals brought it to personal computers and game consoles worldwide.

Walter Mondale Selects Geraldine Ferraro as Running Mate

In the 1984 U.S. presidential campaign, Democratic nominee Walter Mondale sought to energize voters and address gender imbalances in politics amid the Reagan era. On July 12, Mondale announced New York Congresswoman Geraldine Ferraro as his vice-presidential running mate, marking the first time a major American party nominated a woman for the office. Ferraro, a three-term representative known for her work on women's issues and foreign policy, brought experience from the House Budget Committee. The selection followed a competitive search process and aimed to broaden the ticket's appeal to women, minorities, and working-class voters.

Svetlana Savitskaya Becomes First Woman to Spacewalk

Soviet cosmonaut Svetlana Savitskaya had already flown on Soyuz T-7 in 1982, becoming the second woman in space. On the Soyuz T-12 mission to Salyut 7, she joined a crew that docked with the station in July 1984. On July 25, Savitskaya exited the station for a five-hour extravehicular activity alongside Vladimir Dzhanibekov. She tested new tools and performed welding experiments outside the spacecraft, demonstrating female capability in space operations. The mission highlighted Soviet progress in long-duration spaceflight and gender inclusion in cosmonaut programs.

Indira Gandhi Assassinated by Bodyguards

Indira Gandhi had served multiple terms as India's prime minister amid rising tensions, including the 1984 military operation against Sikh militants at the Golden Temple in Amritsar. On the morning of October 31, 1984, as she walked from her residence to her office in New Delhi, two Sikh members of her security detail, Beant Singh and Satwant Singh, opened fire. The attack occurred in the context of communal violence following the temple raid. Gandhi died shortly after, triggering widespread anti-Sikh riots across India.

Bhopal Gas Leak Kills Thousands in India

Union Carbide's pesticide plant in Bhopal, India, stored large quantities of methyl isocyanate, a highly toxic chemical used in production, under lax safety standards common in some developing-world operations. On the night of December 2–3, 1984, water entered a storage tank, triggering a runaway reaction and massive gas release. The toxic cloud spread over densely populated neighborhoods while residents slept. Immediate deaths exceeded 3,800, with estimates of total fatalities reaching 15,000–20,000 over subsequent years from injuries and complications. Hundreds of thousands suffered long-term respiratory, neurological, and other health effects. The disaster prompted global scrutiny of multinational corporate safety practices.

Sino-British Joint Declaration Signed

After two years of negotiations amid uncertainty over Hong Kong's post-1997 future, British and Chinese leaders finalized an agreement resolving sovereignty questions.

It included detailed annexes on governance, rights, and economic continuity. Ratification followed in 1985, and the agreement was registered with the United Nations.
