I am always intrigued by the many ways people use Mathematica. But it was even more exciting to be a part of the American Chemical Society Fall 2009 National Meeting and hear the true excitement and awe of our users' latest discoveries of what is possible in Mathematica. I also had a lot of fun introducing new users to our software! In August, we traveled to ACS in beautiful Washington, DC, USA. The ACS meeting brought together the largest scientific society and its members' families, colleagues, and students. It provided an ideal venue to demonstrate Mathematica's capabilities in chemistry and chemical engineering. We demonstrated a broad range of features, including Mathematica 7's fully curated chemical, genomic, and proteomic data, built-in parallelization capabilities, and unsurpassed modeling and visualization capabilities. The ability to visualize any data as well as update it on the fly has bridged a gap many researchers and scientists have had to work around when using other tools. You can even rapidly develop and test algorithms as well as generate accurate structural renderings in 2D and 3D using the integrated data, which is easy to retrieve programmatically.
