Dirty Chemistry Humour

Similar to my post this morning, here is something that I forgot to put up when it first came to my attention a few days ago. Behold what is probably the most amazing image from an article abstract in years:


When I first saw this, I assumed it was a joke, but it appears to be from a legitimate article. So, to Sergio H. Toma, Miriam Uemi, Sofia Nikolaou, Daniela M. Tomazela, Marcos N. Eberlin, and Henrique E. Toma, I say well done.

Scientist Appreciation: Friedrich Wöhler

One thing that confuses me about Charles Darwin is just how greatly he is demonized by anti-science groups (primarily the fanatically religious). After all, while Darwin did make profound contributions to the field of biology, he is not the only scientist to help expand our knowledge of the natural world into an area that was formerly staunchly under the purview of theology. One other such scientist was Friedrich Wöhler, a German chemist from the nineteenth century.

Though he spent much of his younger days working in various institutions throughout Germany (and even briefly in Stockholm), he spent the final portion of his professional life working in Göttingen (which is why his statue now graces one of the town's squares). Among a copious output of work that included the isolation of aluminium, titanium, and several other elements, Wöhler also began the field of organic chemistry through the synthesis of urea without the aid of a living cell. This turned the idea of a 'vital force' required for generating organic compounds on its head, and brought the exploration of biological organisms within the sights of the physical sciences. In modern terms, he helped spark the development of organic chemistry and thus the related fields of biochemistry, molecular biology, molecular biophysics, and bioengineering.

Of course, Wöhler's singular demonstration of the synthesis of an organic compound did not fully discredit vitalism, but it got things started. Now, the idea of a vital force unique to living beings has been virtually abandoned (outside of a few caveats which I will soon be discussing). What I find strange is that the acceptance of the physical and chemical basis for our bodies has been, for the most part, complete. The previously widespread set of beliefs in various life forces has retreated entirely into the form of an incorporeal and undetectable soul or New Age woo of some indefinable energy that can be somehow helped (expensively) by interior decorating consultations or dubious and mildly unpleasant physical interventions. This retreat, too, has been performed without reference to the historical shift in our perception of life and its constituent parts. There is no demonizing of Wöhler, or false stories of recanting on his deathbed. In actuality, Wöhler is pretty much a ghost in the public mind. Outside of those who study chemistry or have an interest in the history of science, his name barely registers. While part of that may be that chemical synthesis is slightly more direct to demonstrate, as we have seen with the shifting goal-posts of the many incarnations of creationism, scientific demonstration is not actually the point.

I don't really have an answer for this difference in the way history has treated the two scientists, but I do have an appreciation for Friedrich Wöhler's contributions to science. His initial synthesis of urea may have been an accident, but it was no less ground-breaking.
