          <p>Dr. Tyson is an astrophysist and the director of the Hayden Planetarium in New York City. Outside of his career he hosts his own radio talk show called Star Talk, and has hosted and appeared as a guest speaker in numerous television shows. I
            had the pleasure of meeting Dr. Tyson once and can say that his passion for science and teaching those who wish to learn more is genuine. His fun and easy-going style of teaching are the reasons why I believe more americans are interested
            in the sciences today. Let's take a moment to look at a timeline of this amazing person:

     <p> It's hard to see exactly that kind of person Dr. Tyson is by listing things that he's accomplished over his life, so to get a better idea of what kind of person he is, here is a quick video of Dr. Tyson explaining why math and science are important
        to people who are not otherwise involved in those fields professionally:</p>
