Charles Darwin

Charles Darwin

Last month I attended the “9th Annual Evolutionpalooza! – Darwin Day in San Francisco.” The event was at the main branch of the San Francisco Public Library. The short presentation by NASA Astrobiologist Dr. Lynn Rothschild on Darwin and some of his achievements as well as her brief intro on Astrobiology was interesting. Most of the information presented was nothing ground-breaking to those who are avid readers or dedicated scientists/researchers; however, I find it always good to hear information from different perspectives for discussion purposes and for refreshing one’s memory. One of the reasons I love the Bay Area so much is that there are many intellects in the area that are willing to organize events like this and participate regularly in regards to intellectual conversation. Also, the location was ideal as many library attendees who otherwise may never take interest in such a subject had an opportunity to attend and engage. (more…)

Urea

Urea - a molecular compound in human urine

In the past, organic compounds were restricted to those that could be produced only from living entities. These compounds were thought to contain a “vital force” based on their natural origin. This “vital force” concept was disproved in 1828 by a Geman chemist, Friedrick Wohler. Wohler synthesized a molecular compound found in human urine called urea. To accomplish this task he used the molecular compounds ammonia and cyanic acid. Urea became the first organic molecule synthesized by a chemist.
