Putting my concerns on the Table

[This article was first written as an editorial for  the August 2019 issue of The Biochemist, magazine of The Biochemical Society. The issue focused some of the elements that play a major role in the chemistry of life ]

bio04104_cover-figureIn the August 2019 issue of The Biochemist we join with other scientific communities in marking the International Year of The Periodic Table, which celebrates the 150th anniversary of Dmitiri Mendeleev’s groundbreaking systematic organisation of the elements. As our contribution to the celebration we have a collection of features describing facets of the contribution played by several of the elements most important to the chemistry of life.

A recent visit to MediaCity, home to parts of both the BBC and ITV networks, illustrated the reason why I have a love-hate relationship with the periodic table. In ways reminiscent of the cultural appropriation of the double-helix, wider society has taken and abused the notion of the periodic table for purposes that reveal a fundamental lack of understand about its power and significance. Many people are under the false impression that the periodic table is merely a convenient way to put vaguely related things into a series of boxes. The grid on display at MediaCity, for example, was serving to advertise different components of the BBC’s output. A quick Google search also throws up “periodic tables” for beer, cocktails, iPad apps, wrestling, horror movies and even meat. Whatever your interest, it seems, some wag had authored a “periodic table” for it.

There may or may not be an element (no pun intended) of rationality underpinning the clustering of components within such grids. However, even the most logical arrangements fail to recognise the crucial dimension of Mendeleev’s original and its descendants. As most readers of The Biochemist will, of course, be aware the elegance and power of the periodic table is the predictable progression in properties associated with moving across any row or down any column. The astonishing thing about Mendeleev’s table were the blank spaces—gaps left for as-yetundiscovered elements about whose properties he was able to make accurate predictions. Subsequent research not only confirmed their existence, but also Mendeleev’s description of their characteristics.

Random things put in boxes doth not a periodic table make. So, my churlish attitude towards these faux periodic tables largely derives from what is, in effect, their black and white appreciation of Mendeleev’s masterpiece where their ought to be wonder expressed in glorious technicolor.

Now the T-shirt emblazoned “Ah – the element of surprise”, however, that IS funny.

Elemental Business: Snapshots of the chemical industry

Like the man who enthuses about a TV show he’s just seen for the first time, only to find that the recipient of their new-found wisdom has just spent the weekend binge-watching Season 4 in its entirety, there is a risk that this post will be re-introducing you to an old friend. Nevertheless, in case you are (a) interested in chemistry and (b) are not already aware of Elemental Business, here’s a quick summary.

For nearly a year, Business Daily on the BBC World Service the programme has had an occasional feature Elemental Business “looking at the economy from the point of view of the elements of the periodic table”. Correspondent Justin Rowlatt, with the assistance of Prof Andrea Sella from UCL, takes a tour around the industrial and business application of chemicals. I became aware of the series after reading a BBC website article about Bromine. It turns out that there have been at least 24 episodes so far in the series. They are all currently available as both articles and podcasts.

The following links go through to audio for each episode to date. Some elements of particular economic importance (Carbon, Nitrogen and Silicon) have already been given more than one programme,each emphasising a different dimension of their relevance.

All episodes are available direct from the BBC website, including the capacity to download them as podcasts.
