  • Theoretical physicist Stephen Hawking died exactly one year ago, on March 14, 2018.
  • In his later years, Hawking could only “speak” through eye-tracking software due to a neurodegenerative disease.
  • Hawking shared many carefully considered, insightful, and inspirational quotes and ideas throughout his life.

Stephen Hawking – a theoretical physicist, luminary, author, and many other things – died on March 14, 2018, a year ago today. By coincidence, the day is also Albert Einstein’s birthday and a quirky mathematical holiday known as Pi Day.

In passing, Hawking left behind an incredible legacy for a human beings on Earth. He pioneered new understandings of basic physics, mysterious black holes, and the cosmos at large. What’s more, he did so while struggling with a severe neurodegenerative disease that confined him to a wheelchair for the vast majority of his life.

The world-renowned scientist carefully contemplated and composed his thoughts with a special eye-tracking computer, and those words (many of them humorous) continue to inspire generations of people who were curious about how the universe works, where it came from, and where it may be headed.

Hawking supplied no shortage of remarkable insights about life, love, and science. Below, we’ve done our best to collect the most memorable things he said in his books, essays, interviews, TV show appearances, and more.
