When people die their friends always say that they were amazing people. Matthew really was. He was a talented artist (though he never had confidence in that talent) as well as an excellent engineer. He was a vigourous advocate of nuclear power, and could explain at length with facts and figures to back up his claims precisely why it was the only option for power in this century if we want to avoid disastrous climate change. He cared about the state of the world, and acted on his beliefs. He chose to work for Ariva, the French nuclear power company, because of these ideals. He was also a massive supporter of manned space exploration and human colonisation of Mars and we had many long discussions comparing one technology or strategy to another -- from spaceship propulsion systems to the ethics of terra-forming. On top of all of that he was gentle and self-effacing. He never made claims he couldn't back up with evidence, and always underplayed his own achievements. He was a gentleman and a gentle man. He became a vegetarian for ethical reasons. He always went out of his way to help people. He loved to be clean and tidy, and wore a tie and sleeveless jumper even in casual situations. He loved Anime and all things Japanese. He loved technology, propelling pencils, his Macbook Pro, and his iPhone. He stayed up late to watch Steve Jobs giving keynote presentations every time just so as to avoid being spoilered on the new releases and announcements before he got to see the video.
We're all going to miss him.
