# Great Scientist ≠ Good at Math?

April 8, 2013 6:42 AM Subscribe

Do you need to know math to do science? Harvard professor emeritus E. O. Wilson says, "no." Jeremy Fox, an Associate Professor of Population Ecology at the University of Calgary disagrees.

If you try to do general relativity or quantum mechanics without getting the maths, sorry, you ain't getting it.

*Many of the most successful scientists in the world today are mathematically no more than semiliterate.*

Of course he means "semiliterate" in the metaphorical sense of not knowing by heart a dozen ancient languages on top of the usual complete mastery of Greek and Latin, but it still seems like an odd statement. No more than semiliterate.... but nonetheless having completed many thousands of hours of study of calculus, probability, statistics, etc. This has a sort of "Do not worry about your difficulties in mathematics, I can assure you that mine are greater still" arrogance to it.

*For aspiring scientists, a key first step is to find a subject that interests them deeply and focus on it. In doing so, they should keep in mind Wilson's Principle No. 2: For every scientist, there exists a discipline for which his or her level of mathematical competence is enough to achieve excellence.*

It's OK to speak Spanish in the halls.

Echoing three blind mice somewhat, there's a world of difference between being unable to *do* the math and being unable to *understand* it. Being able to read and understand some equations or statistical reasoning is critical. Being able to create that work is not, necessarily.

That seems a bit specious. He doesn't need to know the math, because he can easily find somebody to do the work for him?

I am a biologist with very average math skills, and as such I think I read what Wilson said with a little more charity than I would if I was a computational or population biologist. What I read was a suggestion that students with an interest in biology should remain in biology programs, even if you're not very good at math. He's encouraging people who might not have had the best elementary or early educations to stick with the field. In my mind, this is an excellent idea, as the people teaching and working in the field are remarkably un-diverse.

I think what Wilson is saying is essentially this: You don't need to be an accountant to run a business, you can hire, trade or collaborate with one. You do need focus though.

*If you try to do general relativity or quantum mechanics without getting the maths, sorry, you ain't getting it.*

But there is a lot of other science which requires only a moderate amount of maths - I've known chemists, zoologists, botanists, psychologists, even epidemiologists who have only undergraduate level maths and probably would not describe themselves as being especially talented in maths. When they need to do higher level maths, they collaborate with statisticians, etc.

The point is that people should not write themselves out of science just because they are only average at math. No, they will probably not be theoretical physicists. But they may do perfectly fine in hundreds of other fields - many of which (eg health) have better job prospects.

Wilson doesn't discount the power of mathematical knowledge, but points out that for many scientistis — even those with great mathematical talent — scientific discovery is not just a number-crunching exercise. Many discoveries are made via intuition and abstract thinking, and then later confirmed by mathematics. He is not saying that that is how every discovery is — or should be — made, and I honestly don't understand why people would read the article to imply that.

Can't second this enough. And the reason this is true? The statistician has to be educated to the science behind the experiment to the extent that she can choose the proper experimental design and and statistical analysis. If you've never worked with a good statistician before, you will be surprised at the depth of subject matter knowledge necessary for good design and analysis.

*Wilson's Principle No. 1: It is far easier for scientists to acquire needed collaboration from mathematicians and statisticians than it is for mathematicians and statisticians to find scientists able to make use of their equations.*

Dear god, this. This for an hour. I am currently dealing with an electrical engineer, a guy who has this really complicated method of analyzing mRNA microarray data as "nodes" in some complex modeling system to determine what genes are most important or most inter-related between two or more groups. It doesn't work without massive amounts of data points. Problem is, he has ZERO idea what it all means, nor does he care. He shoves out a pile of data, says "these are the important nodes" and then asks (I am not kidding here) "What physiological process or behavior is this data modeling?" I cannot fathom this approach. In my field, we define the problem first and then plan the study, not the other way around. He has a method and is looking for a problem he can solve with it. It boggles my mind.

And it isn't even data, per se. It's a list of line numbers from an Excel file. No matter how many times I ask for it, he can't even use the individual gene accession numbers as identifiers, he uses the line numbers from the spreadsheet, because to him it's just a big math problem while to me and my colleagues there is no point in pursuing it if the "nodes" (genes) actually have fuck-all to do with the behavior we are trying to explain. And unless I know with absolute certainty there is a 1:1 correlation between line numbers and gene accession numbers, I can't look up the genes and verify that ANY of them are involved in our behavioral measures.

He wants to know where we are going to publish it, without understanding that you can't just crunch numbers and send it off in biology. There must be some connection to reality. The model is not the interesting part, unless you have also shown that the model accurately reflects the biology.

Jpfed: "

*By the way, if you're interested in doing an experiment and want the help of a statistician... get them involved before you do the experiment, not after.*"

...unless, of course, the statistician gives you bad advice and leaves you with ~$10,000 of wasted microarray data because he asked a grad student to design the experiment for you and now can't explain exactly what the setup was and his analysis of the data makes zero sense, biologically. Because then, you're stuck asking an engineer with a really complicated model if there's anything you can salvage from the study.

(I guess this is what I get for saying "Gee, sure, I'll take a look at that old microarray data and see what we can do with it...")

This is as true in mathematics as it is in any of the empirical sciences. Pure mathematicians put a great deal of effort into developing "intuition" as to what is going to be true and what isn't. But I will just replace every instance of the word "mathematics" in this thread with the word "computation", and keep on reading.

**caution live frogs**, I hear you a thousand times over. I took the Introduction to Machine Learning class while getting my Master's in Computer Science and I remember how in every class session the professor would go up, start with an intial equation, and very carefully walk through the derivation of a model that it was actually possibly to implement, pointing out pitfalls along the way and writing down every step.

After he had done this I'd raise my hand and ask what kind of data this was good for, and his reply, every single time, was completely abstract - "You have a classification problem where you know the number of classes", "You have a lot of samples and a small number of dimensions", and so forth. I would then ask what an actual example of such a data set was, and thankfully I got an answer, but it always took pushing.

A few of the homeworks had very obvious data sets - the Iris one, simple handwriting recognition for Arabic numerals - but most of them weren't labeled at all, and I remember asking what the sample data we were given on one assignment was and waiting a few days for one of the TAs to figure it out. It was only important as dots on a graph.

The thing that really upsets me about this is that while the derivations are very important, particularly in that they help you understand

*why*each model has its own peculiar strengths and weaknesses, just knowing the right method to use in a given situation and using a pre-packaged solution like SciPy opens up a world of research possibilities to people who are never going to make a classifier that's .01% better on a given standard data set but still have work that needs doing.

I find it heartening that there's guides to data analysis that aren't focused on implementing well-understood algorithms from scratch any more - I just saw a link to this Practical Intro to Data Science the other day - and I hope to see more of it.

It's also more complex than "Is numerical ability as a precondition of biological understanding? Y/N"

Biological systems are messy and noisy; full of uninteresting nonlinear interactions and low effect sizes. Most physicists I know find it inconceivable that there could be anything actually worth knowing about the things I work on - and that's a direct quote from one of the nicest ones ;)

I think, by that, she meant "satisfying to know", which is sufficiently subjective that I didn't feel offended. This of course doesn't mean you don't need numerical ability to get the most out of those messy systems, just that the physicists' search for universal laws isn't the primary reason biologists get involved in biology (or more accurately that the universes we work in are smaller).

And, conversely, Fox's own field of population ecology (as are a lot of biological fields) is changing rapidly because of the insights from metagenomics - and that was because someone had both the bright idea to go looking for wide-scale microbial patterns over time and the technology to do so - and had nothing really to do with mathematical ability at all. So for me, Wilson's right that the big ideas aren't constrained to come from advances in applied mathematics within a field, but wrong in not recognising that the numerical barrier to entry is getting higher every year. Both, not one or the other.

I had a transformative experience with this issue while reading "Wind Waves" by Blair Kinsman (written in the '60s). An older (1st?) edition of this book (not the one I can find on-line) had a preface about the mathematics necessary to understand the book. It was a little bit of a rant about how mathematics is a tool that scientists use to beat other scientists with, and how it shouldn't be that way.

If you can find the edition with this preface, it is highly recommended reading.

The bottom line is that mathematics for science can and should be always easily explained to other scientists. If it can't be, it either isn't useful, or someone is being a jerk.

While Wilson might be technically right that scientific ability is distinct from mathematical ability, at least in some fields of science, I think that publicizing this argument will do more harm than good in the long term. As it is, in the US there is a culturally-ingrained distaste for math, which results in very few pursuing mathematical training. The more the students are told that they can achieve everything they want without math, the fewer mathematically trained professionals there will be. If that trend persists long enough, eventually all those biologists, for instance, will find mathematical collaborators increasingly hard to find.

'Cause math majors learn how (at least a little bit) how to construct logical arguments, accounting for all possible complications (admittedly in a subject area that in some ways is much simpler than law, due to the things that math majors have to construct arguments about being well-defined).

*It's almost interesting that Mathematics is considered a separate discipline from the sciences. Math is a toolkit for doing science, and that the composition and use of that toolkit varies considerably and distinctively from one field to another.*

Well, there's math, and applied math. Mathematics as an academic discipline is the deductive study of mathematical objects - abstract things with precise definitions. Some fields of math involve calculation; others involve shape; others are much more abstract. But in all cases the "mathematical method" is logical deduction and argumentation. That's quite distinct from the scientific method; math, as an academic discipline, is not a science. But yeah, results from mathematics - applied math - are extremely useful in the sciences.

*I would say that testing your scientific ideas will go better if you are skilled at math. Designing your experiments certainly will. But making the observations that lead to the experiments requires intuitions that can be independent of math.*

Most of science has moved beyond simple, qualitative descriptions of phenomena. Mathematical models are now at the heart of most useful sciences. It was no accident that statistics and genetics co-evolved or that mathematical computer models are used to identify novel molecules that can treat specific disorders. Math is not at the periphery or just used to get a p-value, but is at the core these days.

And yet, most of molecular biology from the 70s onward made essentially no use of statistics (beyond basic hypothesis testing) to say nothing of mathematical modeling. Even if you crack open a copy of Cell these days, the most quantitative thing you're likely to see is a growth/survival curve or a bar chart. (Maybe a heat map!)

Don't get me wrong, for a biologist I am a big proponent of stats, coding, and math and think a lot of scientists would benefit from a better understanding of these fields. But there's certainly a lot of elegant scientific reasoning that you can do with an extremely basic mathematical toolkit.

I think my (very strong) opinion runs pretty counter to the general feeling of this thread. First, Wilson didn't need math skills because he was a biologist in the 70s, when getting a partial sequence of a single gene was a Nature paper. Not much math needed then, biology was a different thing.

Now we have systems biology, neuroscience and population biology all moving in a pretty mathy direction. Molecular biology is morphing with biophysics and becoming pretty mathy as well, especially when you talk about drug design and/or large scale data analysis. To wit:

The problem here is that one person, who understands both the math and the biology is the right person to do this job. You can definitely be a biologist these days and not understand math beyond the basics. However, you're more and more likely to be outcompeted by the people who are complete scientists.

I tend to find the idea that scientists should be able to be great at more than one field kind of absurd. It's like telling an athlete that to be a 'whole athlete', they have to be both an amazing marathon runner and baseball pitcher, or some other combination. You might get good at both, but you also risk being surpassed by specialists at either, since you are splitting your time between learning two things. Probably the best you can really hope for is to be great at one and fair at the other - but then you have to wonder if the best strategy would be to just have two different specialists collaborate.

Mitrovarr, I agree that it's very hard to get deep training in multiple fields, but even if you bring two brilliant people together from different disciplines, you can still end up wasting a lot of time while they speak completely disjunct languages at one another.

But I think that points to the existence of multiple niches within the scientific community: some people are going to advance human knowledge by being a world-class expert on a single technique or topic, while others are going to contribute by synthesizing and combining ideas from disparate regions of science. I'm not sure I have any evidence that one is more valuable than the other.

But getting back to Wilson. The problem with the eusocial darwinists (like Fox) inspired by Wilson is that they are no more aware than the individual competition theorists they are arguing against that the sophisticated equilibrium models they exploit have baked in philosophical/scientific assumptions. When you have a mathematical model that works, there is a terrible pressure to make the interpretation fit the math... which only says you don't really understand your model in the first place.

Seems to me that the fault often lies with empiricists who stick with their intuitions come hell or high water, and who actively resist the discipline that mathematics imposes on their groundless daydreaming. Intuition is great–as long as it’s only a starting point, and as long as you’re prepared to give it up when it’s proven wrong, even if there’s no better intuition to replace it with. Unfortunately, that’s really hard to do.Fox seems to imply that the mathematics is value neutral, when it never is.

One more thing regarding Wilson, I find his attitude that he doesn't need to know math because he can always find someone else to do it for him very strange. I am a researcher who publishes with collaborators, but I would never dream of putting my name on a paper with significant chunks that I don't understand. Certainly the point for collaborating with others is that they bring knowledge and ideas that you don't have, but taking things on faith is bad practice and a recipe for trouble. Actually, to me one of the great joys of collaborating with others is that I learn something new about a different field each time.

cromagnon beat me to it, but you really have to appreciate just how messy and variable biological systems are. It's not that biomed researchers don't care about quantitative questions, it's that the answers tend to have very limited reliability and specificity. The values you get depend not only on the experimental model and the analytic technique used, but also on the time of the day, the temperature, the Dow Jones Industrial Average, and the alignment of Jupiter. And for practical and economic reasons, you're generally stuck with an

I am a geologist. My math skills are quite average, meaning I understand and can do calculus. Geology used to be a softer science, but I remember when I was in grad school back in the 1980's my fellow grad students would joke "you can't just map it anymore". And I remember talking about an idea with my first adviser. She said "That is interesting. I wonder if it is thermodynamically possible?" (gulp). So, this is very true in the geosciences today. Most significant problems in geology today involve a lot of physics and/or chemistry and will involve some type of mathematical modelling. So the problem I have as a geology professor is to get the undergrads to appreciate this. I wish I could take them all to AGU in San Francisco for a day and have them walk the posters. That would be an eye opener for them I think.

You don't have to be stellar at math. You just have to speak it. Three semesters of calculus and one each of linear algebra and differential equations will get you through 99% of the math needed to do modern biology, including the data analysis live frogs was talking about. Just about anyone can do that. Just don't run screaming when you see a matrix and you can handle systems biology. Don't try to act like you need two PhDs to understand it, that's just not true. All you need is those five undergraduate math courses.

The problem is that undergraduate biology programs haven't caught up with the idea that math is no longer optional. I suspect this is mostly driven by fear of blowback from the hordes of premed biology majors, who will quite likely riot if forced to take calculus.

I don't care if they don't have predicate calculus, but they need to be able to use and understand stats. Actually, I take that back, they do need calculus because they need to understand differential equations too.

It's not enough to hide in your lab or your field camp and claim to be an experimentalist. Nor has it ever been. There are a lot of stamp collectors in science. Don't get me wrong, data gathering can be a lot of fun, and I do a great deal myself, but it's only one part of the whole.

You need to design experiments: that needs stats. You need to hypothesize, either from new data or old. That needs both stats and math. You need to conduct your measurements with some sort of QA/QC, stats again. You need to test the hypothesis, again with stats.

What Wilson calls intuition has to ultimately lead to model formulation. It's true that this is often done collaboratively, but even the most ardent stamp collector needs to be able to talk to the biometrician.

That's where I think his argument falls apart. A feel for one's subject is an essential part of a researcher's intuition, but not being able to translate that into quantifiable terms is like being a composer who can't write their own music. Mozart didn't compose by humming to his librettist. A naked intuition is almost impossible to test---it has to be formulated into a hypothesis. The way hypotheses are formed and tested fundamentally relies on mathematics, like it or not.

Again, though, this is not true in molecular biology, which got along fine for decades with very little reliance on mathematics. Most "models" of cellular mechanisms in this field are summarized as arrow diagrams. You could argue that these models can be mathematized, and that would be true (as well as being one major aim of systems biology, I think), but that still would have very little relevance to how these models have been used or understood in the field. Even statistics has historically not played a particularly major role in interpreting, say, Western blots or gel shift assays.

Pick an area of mathematics, it's likely that even a full-fledged capital-M Mathematician working in it is going to need assistance from another one at some point if they're doing any significant let alone groundbreaking work.

When the totality of the knowledge in your field no longer fits inside the brain of one person any longer, there really shouldn't be any shame in relying on others.

OTOH, where we're not necessarily talking about the totality or even significant subfields, but rather a subset of math/stats that's vastly useful across the sciences, I think there's a case to be made that everybody working in any science should know that better. Wilson seems to agree.

Both of these articles are really interesting to me.

No it doesn't.

You formulate hypotheses by thinking about what the world (or whatever chunk of it is relevant) would be like if your theory were true. In some circumstances you can use mathematics to make very precise hypotheses, but imprecise ones aren't unscientific. Just imprecise.

You test hypotheses by comparing your hypotheses with observed empirical reality. If you're willing to make whatever series of heroic assumptions are required, you can use mathematics to determine what the bounds of uncertainty around your results are. Or at least what they would be if those assumptions were true, which they never are.

tl;dr: there is such a thing as qualitative science.

There's a culture difference for you then. In my field, papers which would have been accepted with qualitative hypotheses even a decade ago are not getting past review now. I'm not sure how I feel about that to be honest, but it's a thing.

Well, like I mentioned, my university has a statistician on staff for that exact purpose.

And if you don't, you can still try asking the appropriate professors.

I understand what you are saying, but it's still true that someone who splits their effort between multiple things can't spend as much time on any of them individually as someone who focuses on one. Having basic mathematical literacy is good; it's a basic component of any graduate biology degree. However, taking the time necessary to be a great statistician would cripple you as a biologist.

I kind of think my thesis suffered from this a little bit, actually. I did a molecular phylogeny of a group of fungi (it's submitted but not approved yet, we'll see how that goes. The first chapter is already published.) One part of the project involved a lot of molecular biology, gene sequencing, and phylogenetics. The other was a huge lit review and discussion of the morphology within the group. Honestly, I think it would have been better if the lit review and mycology component could have been offloaded to someone who has practice at that sort of thing - I didn't have enough time to get really comfortable with that aspect. I could have used that six months to improve the phylogenetics and maybe get more genes, or perhaps just to graduate on time.

Certainly lots of early genetics could have been done by altering one gene and seeing what happens.

But, I wonder

*this point*how many experiments with unambiguous answers there are out there. If you look at the large hadron collider, for example they got a ton of data and had do a lot of analysis to identify the signal they were looking for.

*much*evolutionary pressure it requires to preserve interacting networks of genes based on their complexity (i.e. if a single mutation is more likely to break it's less likely to be preserved compared to something that provides less fitness but is less likely to break from one mutation).

Of course I don't know the actual formulas you would use, they might only require basic algebra/calculus and seem pretty obvious to a real biologist :P. Then of course there are much more complicated things like the physics of protein folding, how quantum interactions come into play, the mathematical issues involved in morphogenesis. (Actually I just looked that up got reminded that

*Alen Turing*of all people came up with some of the key ideas)

I do think you can get to a point where math kind of goes off into it's own totally abstract space where it starts to become less and less likely to have any real-world applications, so there probably is a point of diminishing returns.

J.B.S. Haldane is a good example of how mathematical knowledge is important in biological science. He was a professor of genetics and the first Weldon professor of biometry at University College London. His mathematical abilities were key to his enormous contributions to genetics and biology and to other scientific contributions he made. There are many other notable examples, such as G. E. Briggs, Leonor Michaelis and Maud Menten. The need for mathematical rigor is only going to get greater as biology progresses.
