1. Jane Goodall.
1960年，在26岁时，Goodall开始在坦桑尼亚的Gombe Reseal National Park的Chimpanzee行为中研究，并从那以后一直在学习和倡导灵长类动物。1977年，她建立了Jane Goodall Institute.保护灵长类动物及其栖息地，现在拥有19个办事处。近年来，这种素食主义者倡导其他动物，包括农场动物。“成千上万的人说他们”爱“动物每天坐下一次或两次，享受被治疗的生物的肉，因为越来越尊重，只是为了制作更多的肉，”沃尔已经说过。她也成立了Roots and Shoots, a youth-led action and educational program and resource for kids that has programs in more than140 countries. At 82, Goodall still travels the world more than 300 days a year, advocating for animals, teaching, speaking and educating both children and adults about our closest living animal relations.
2. Carl Sagan
Sagan is the only non-living person on this list, but he might be the first modern-era popularizer of science. Born and raised in Brooklyn, he attended the University of Chicago for undergraduate work through his PhD, studying both genetics and planetary sciences during the 1960s in graduate school. He published more than 600 papers and wrote, coauthored or edited 20 books, focusing on cosmology, astrophysics and astronomy. He was a skeptic who promoted the search for extra-terrestrial life (he worked for NASA beginning in the early days of the space program), and he was known as a deep thinker who was a "liaison between the sciences据美国航空航天局称，“他的PBS电视系列”宇宙“（上面的第1集）（上面的第1集）（剧集）（第1集）达到了超过5亿人。
3.尼尔 - 泰森
如果你没有听说过泰森，你必须生活在岩石下。那个男人到处都是白色的房子。NYC出生和养殖的泰森去了哈佛（在Sagan试图招募他到康奈尔）然后哥伦比亚大学，他在天体物理学中获得了博士学位。1994年，他加入了纽约的海登本地学院 - 在那里他受到启发，以便在1996年到1996年被指控乘坐宇宙。一位着名的演讲者，他被赶上了“Nova ScienceNow”并出现了“Nova ScienceNow”并出现了经常在历史频道的“宇宙”上。2014年，他举办了一场逃离狐狸的Sagan的“宇宙”的重启。他的电视节目，“签名," airs on the National Geographic Channel.
4. Bill Nye.
Nye once came under fire by Sarah Palin prior to the White House Science Fair, when she told lawmakers that Nye was "...as much of a scientist as I am,"根据沙龙的说法。这并不是那么真实 - NYE在康奈尔学习机械工程（他也拿了一个由Sagan教授的课程）。然后，他作为一个工程师在波音公司举行，每隔几年才能成为美国宇航局的宇航员，在那里他总是被拒绝。他从1993年到1998年逃跑的“Bill Nye”的电视节目“Bill Nye”，仍然是重播，并用作科学课堂的教学助手。一代人在他的表演中长大，每一集都集中在一个特定的物理学，生物学，天文学，植物学或其他科学主题领域。在四月份，他会回到电视with "Bill Nye Saves the World," a Netflix series in which he'll bust myths, do demonstrations and explore scientific issues with celebrity guests.
5. Danica McKellar.
McKellar is well-known for her role on the popular '80s drama "The Wonder Years," but she has since parlayed her popularity about as far from teenage angst as you can get: Math. After graduating from UCLA summa cum laude with a degree in mathematics, she's written and directed films and continued to act, with guest roles on TV shows like "The Big Bang Theory" and "How I Met Your Mother." She has written four books aimed at young women: "Math Doesn't Suck," "Kiss My Math," "Hot X: Algebra Exposed" and "Girls Get Curves: Geometry Takes Shape." Now she hosts a series on Nerdist called "Math Bites" (see above) and speaks and teaches around the world about math and related topics.
6和7. Jad Abumrad和Robert Krulwich
Abumrad and Krulwich are the stars of NPR's popular radio program, Radiolab. While not strictly a science show (they call it a "curiosity-driven"), they have tackled subjects from neurobiology to the environment to the beginning of life to quantum physics. As Krulwich says in the clip above, "There's an adventure to this. We choose complicated subjects, we don't completely understand them all the time, and then we try to make sense of them. To do that you have to have fun, you've gotta experiment."
8. Randall Munroe.
Munroe worked as a roboticist for NASA until 2006 when his contract wasn't renewed — so naturally he became a cartoonist. While he started the comic part-time in 2005, he dedicated himself to it after leaving NASA and its popularity allowed him to work on it full time. In his own words: "I was going through old math/sketching graph paper notebooks and didn't want to lose some of the work in them, so I started scanning pages. I took the more comic-y ones and put them up on a server I was testing out, and got a bunch of readers when BoingBoing linked to me. I started drawing more seriously, gained a lot more readers, started selling T-shirts on the site, and am currently shipping T-shirts and drawing this comic full-time." The comic,XKCD.，涵盖计算机科学，技术，数学，科学，哲学，语言，流行文化和浪漫。他于2009年发布了一本XKCD书籍，维护了一个博客 - “如果是怎么办？”- 这回答了读者的科学查询，这成为2014年的另一本身。His latest publication is "Thing Explainer," which endeavors to parse complex ideas using simple language (see video above). In 2017, selected comics from xkcd will be incorporated into textbooks by Houghten Mifflin Harcourt.
Sethi is a journalist who started out at MTV making documentaries, but by the 2000s she had co-wrote an award-winning book, "道德市场：种植绿色经济”。(她还为Treehu托管和制作视频gger.com — a sister site of MNN.) She hasn't strayed far from covering, explaining, writing and researching environmental issues since. She was recognized as an environmental leader in Vanity Fair and other magazines and websites in the mid-2000s. Sethi then became host/digital contributor to the PBS series "QUEST: The Science of Sustainability," appeared as an environmental expert on "The Oprah Winfrey Show," "Ellen" and many more. She also hosted the Sundance Channel's web series "The Good Fight," which took a close look at environmental justice issues. Sethi teaches, writes and continues to speak publicly, with a current focus on food in her new book, "Bread, Wine, Chocolate: The Slow Loss of Foods We Love."
Alda is an actor who has blended his affability with his love of communicating science. His acting has run the gamut from playing Capt. Hawkeye Pierce on "M*A*S*H," which ran for 11 seasons, to "The West Wing." But it was his 14 seasons of hosting "Scientific American Frontiers" that brought him to the fore as a science communicator. Alda is currently a visiting professor at Stony Brook University in New York, and a founder and member of the advisory board of both the Alan Alda Center for Communicating Science and theFuture of Life Institute。Alda'sflame challenge, which aims to demystify scientific concepts, poses questions to scientists like, "What is a flame?" "What is time?" and "What is sleep?" with explanations that an average 11-year-old could understand.
