<a href="/people/ancient_epoch/eratosthenes.html&dev=1">Eratosthenes</a> was a Greek scientist who lived from 276 to 194 B.C. He studied astronomy, geography, and math. Eratosthenes is famous for making the <a href="/the_universe/uts/eratosthenes_calc_earth_size.html&dev=1">first good measurement of the size of the Earth</a>. This portrait, drawn long after he was dead, shows what the artist thought he might have looked like.<p><small><em>Public domain.</em></small></p>Science educators on a research immersion experience with the <a href="/people/postcards/andrill/andrill_post.html&dev=1">Antarctic Geological Drilling Project (ANDRILL)</a> sent postcards to Windows to the Universe while they were in <a href="/earth/polar/antarctica.html&dev=1">Antarctica</a> from October 2007 until January 2008. The team drilled into <a href="/earth/geology/sed_intro.html&dev=1">sedimentary rocks</a> below the ice of the Ross <a href="/earth/polar/cryosphere_iceshelf1.html&dev=1">ice shelf</a> to help learn more about the environmental changes that have affected the continent in the past. This image shows what life is like in a field camp on the ice.<p><small><em>Image courtesy of Julia Dooley </em></small></p>Jocelyn Bell Burnell is a British <a href="/the_universe/uts/ast_history.html&dev=1">astronomer</a> who was born in 1943. She discovered <a href="/the_universe/NS.html&dev=1">pulsars</a> - <a href="/the_universe/Stars.html&dev=1">stars</a> which emit periodic radio waves - in 1967. Burnell was a graduate student at Cambridge University when she discovered pulsars. Her professor, Antony Hewish, received the Nobel Prize in Physics for her discovery.<p><small><em> The Open University</em></small></p><a href="/people/postcards/vocals/dione_rossiter.html&dev=1">Dione Rossiter</a> is a scientist that participated in a research expedition to understand the climate of the southeastern Pacific in fall, 2008 - the <a href="/vocals/vocals_intro.html&dev=1">VOCALS campaign</a>. She got to fly a her scientific instrument aboard a research aircraft above a layer of <a href="/earth/Atmosphere/clouds/stratocumulus.html&dev=1">stratocumulus</a> cloud that seemed to go on forever.<p><small><em>Image courtesy of Dione Rossiter</em></small></p>Although we humans have never experienced fast <a href="/earth/climate/climate.html&dev=1">global warming</a>, our planet has. And our planet keeps records of what happened. The oldest records that the <a href="/earth/earth.html&dev=1">Earth</a> keeps are in its <a href="/earth/geology/sed_intro.html&dev=1">rocks</a>. In this image, <a href="/headline_universe/olpa/methane_28may08.html&dev=1">geologists Chris von der Borch and Dave Mrofka</a> collect sediment samples in South Australia. These rocks hold clues to help explain why climate changed abruptly 635 million years ago.<p><small><em> Courtesy of Martin Kennedy, UCR</em></small></p>
