尼尔·德格拉斯·泰森，美国天文学家，专精宇宙学，博士后之后不再做前沿学术研究，转型为向大众推广天文学的科学传播者，因此闻名美国，获美国国家航空暨太空总署杰出公共服务奖章、美国国家科学院杰出公益奖章。美国自然史博物馆天文物理部创始人兼助理研究员，亦是该博物馆辖下罗斯地球与太空中心内海顿天象馆馆长。 “The good thing about science is that it"s true whether or not you believe in it.” “For me, I am driven by two main philosophies: know more today about the world than I knew yesterday and lessen the suffering of others. You"d be surprised how far that gets you.” “We are all connected; To each other, biologically. To the earth, chemically. To the rest of the universe atomically.” “We spend the first year of a child"s life teaching it to walk and talk and the rest of its life to shut up and sit down. There"s something wrong there.” “Curious that we spend more time congratulating people who have succeeded than encouraging people who have not.” “The Universe is under no obligation to make sense to you.” “The more I learn about the universe, the less convinced I am that there"s any sort of benevolent force that has anything to do with it, at all.” “... there is no shame in not knowing. The problem arises when irrational thought and attendant behavior fill the vacuum left by ignorance.” “There"s as many atoms in a single molecule of your DNA as there are stars in the typical galaxy. We are, each of us, a little universe.” “I would request that my body in death be buried not cremated, so that the energy content contained within it gets returned to the earth, so that flora and fauna can dine upon it, just as I have dined upon flora and fauna during my lifetime” “I look up at the night sky, and I know that, yes, we are part of this Universe, we are in this Universe, but perhaps more important than both of those facts is that the Universe is in us. When I reflect on that fact, I look up—many people feel small, because they"re small and the Universe is big, but I feel big, because my atoms came from those stars.” “My view is that if your philosophy is not unsettled daily then you are blind to all the universe has to offer.” “Knowing how to think empowers you far beyond those who know only what to think.” “Not only do we live among the stars, the stars live within us.” “We are stardust brought to life, then empowered by the universe to figure itself out—and we have only just begun.” “God is an ever-receding pocket of scientific ignorance.” “After all, what nobler thought can one cherish than that the universe lives within us all?”
