Publishing at age 91

When physicist and astronomer James Van Allen passed away at age 91, one of the best scientist of our era was gone. I hold much admiration for this man who discovered the radiation belt named after him and who tirelessly strived to educate poeple about the beauty of space and the political elite about its dangers and opportunities. He famously argued against a manned mission to Mars, saying that robots could do more for less. Ultimately Bush's decision was more about politics than science. This nice article outlines this man who despite his age never quit researching and publishing until the very last day because of his love for science.
