That discovery, made together with his astronomer POSTDOC JOURNAL sister Carol, stunned colleagues. It not only yielded the first images of many simultaneously exploding stars inside a galaxy, but also altered the prevailing theory of how Waiting with baboons galaxies generate intense radio sources called masers, I have found it hard to return to my research in Ethiopia after my six-week according to long-time colleague Phil Diamond, director of hiatus. The fear of the unknown is gone, but so is some of the excitement. And the Jodrell Bank Centre for Astrophysics. Diamond says it this time, I have no one from the outside world with me.

And, as any semi-sane person can tell you, having too In 2000, Lonsdale turned away from pure research, much time for your own thoughts can be utterly destructive. instead devoting his time to developing the Murchison For the first few days here, I ranted and raved silently, even finding it difficult Widefield Array (MWA), an array of low-frequency radio to go outdoors. It was too much ‘reality’ hitting me — I’m here and I’m more or telescopes in Western Australia. He says the MWA, less alone. I considered the gelada baboons my only distraction, and negativity scheduled to begin operation in 2010, will target questions threatened to devour me. I had to try to see the positive aspects of this such as how to measure solar storms accurately. experience. After all, I want to be here and I love my job. How can I deal with the Lonsdale says advances in digital electronics have circumstances surrounding it? opened up a new frontier in radio science. Diamond fully I came to see that I have been given something that I never had in the city: expects that Lonsdale, who got funding for the MWA in time. It is a precious thing, and not all that frightening. Now I am filling my time with the things I never get to do back home — reading articles, doing extra difficult times, will use his expertise to help position MIT’s analyses, working overtime and writing letters. And I’m finding it a positive involvement in the next generation of radio-telescope experience. I still love all social distractions, but I don’t constantly bemoan my technology — the Square Kilometre Array. Diamond is solitude. Only my attitude has changed. Perhaps that’s enough to carry me optimistic about the effect Lonsdale can have on this through. ■ ■ project, which he calls “the big daddy of radio astronomy”.
