Earth sciences
- December 21 – Mexico's Popocatépetl volcano, dormant for 47 years, resumes eruption.
Mathematics
- September 19 – Wiles' proof of Fermat's Last Theorem: Andrew Wiles devizes a new approach to the final proof of Fermat's Last Theorem, sending his proof to colleagues on October 6 and submitting for publication on October 24.
Molecular biology
- Green fluorescent protein is successfully expressed in C. elegans, starting its career as a fluorescent marker.
Technology
- May 6 – The Channel Tunnel, which took 15,000 workers over seven years to complete, opens between England and France. It is now possible to travel between the two countries in 35 minutes.
- August 16 – The world's first smartphone, the IBM Simon, goes on sale.[18]
- December 3 – The first PlayStation gaming console is released in Japan.
- The first high-brightness blue LED is achieved, an invention that earns the researchers a Nobel Prize in 2014.[19]
