Last weekend journalist Rod Liddle applauded the efforts of two scientists who wrote a primer for the lay public on physics. His applause stopped when it came to the content though. The problem for him was the quantity of maths the authors used to get their point across. Liddle wrote “By the time we got onto calculus and derivatives I had long since raided the wine rack and things stopped making sense altogether.” But calculus is an integral part of the Leaving Certificate maths curriculum in Ireland and A levels in the UK so why should an educated man find it so intractable? Well, for one, maths is often taught in the abstract.

Of course many of us struggle with the abstract world of maths so this isn’t restricted to Rod Liddle. And I realise that not everyone can be a master of all trades. The trouble is, maths is damn useful, and in science it’s indispensable. Look at how Eugene Wigner spoke of the ‘Unreasonable Effectiveness of Mathematics in the Natural Sciences.‘

In secondary school and throughout university I thought biology was almost a maths free science. How wrong I was. If you ignore the quantitative part of biology you miss a wealth of literature and hamper your understanding of the subject. Without statistics much of biology would be stamp collecting. So it’s worrying that a maths-phobia has infected biologists. Look at this study showing that as the number of equations in a biology paper increases the number of cites it gets goes down. There even seems to be a split in the biological community, the theoreticians on one side and the empiricists on the other.

Back in 1959 the chemist C.P. Snow gave a Rede Lecture in which he decried the split between the sciences and the humanities. He called this ‘The Two Cultures‘. I don’t think we’ve bridged that gap. But I’d hope that biologists can improve the way they communicate with one another. Every effort should be made to make a scientific paper as clear as possible.

This will have to come from both sides. Those quantitative minds will have to make it clearer what they’re talking about. I suggest using in-text drop down boxes to make every step explicit as the number of equations ratchets up. This shouldn’t be a problem as we move away from paper publications and use all of the tools the digital age affords us.

But there is an onus on the rest of us to up-skill. Fortunately this has never been easier. A large proportion of MOOCs are mathematically themed and sites like the Khan Academy are a fantastic resource. A real boon of these courses is they afford anonymity, so you can safely check out logarithm identities without embarrassment.
