\begin{abstract}
Hi Reddit, I've been a science reporter for more than 30 years. I have a
PhD in Psychology from UC Santa Cruz. I have worked at Nature, Science,
and now NPR. Over the years I've traveled around the world covering
science stories: from to the South Pole to the top of Mauna Kea, to
inside the plume of the Eyjafjallajokull during its eruption in 2010.
I've been at the Jet Propulsion Laboratory while 5 different probes
successfully landed on Mars, I've been to Stockholm to watch the King of
Sweden award the Nobel prizes, and I've interviewed many of the world's
top scientists: Jim Watson, Francis Crick, Carol Greider, Martine Reiss,
Andrea Ghez, Roger Angel, Jennifer Doudna\ldots{}you get the idea. I
host a series called Joe's Big Idea that focuses on the minds and
motivations of scientists and inventors. The ``Big Idea'' is to present
science not as a set of discoveries but a process of understanding. Most
of the news media depict science lurching from breakthrough to
breakthrough. I want to show the hard work, frustration, creativity,
persistence and occasionally joy that truly represents what science is
all about. Want to see what I'm up to and chat with me after this AMA?
Message me and follow me on Facebook at Joe's Big Idea. I will be back
at 1 pm Et to answer your questions, Ask me anything. I am blown away by
all the interesting questions. You have set the bar very high. I've been
writing answers for a couple hours now, and if I could only type faster,
I'd answer more. I hope this discussion we started today can continue.
I'm very committed to accurate communication of science, and welcome
thoughts, ideas, and critiques going forward. I'll watch /r/Science for
questions going forward, or you can get in touch via the Joe's Big Idea
Facebook page or joesbigidea@npr.org%
