# why do you need calculus for biology

I benefited a lot from my wife's experience as a math-friendly biologist. Differential equations are used to model e.g. I have no data. @MattF. What I mean is, it involves physics principles and algebra along with geometry to find a solution to a problem or to find an answer to a question. I work with them a lot and the ones who truly understand what a p-value is tend not to abuse statistics as much as the ones who don't. At the end of the day, all science is 'applied mathematics'...without the math supporting your observations, you greatly limit yourself in your chosen field. https://matheducators.stackexchange.com/questions/2060/how-is-calculus-helpful-for-biology-majors/2087#2087. ), https://matheducators.stackexchange.com/questions/2060/how-is-calculus-helpful-for-biology-majors/2065#2065. Grad student: none. But then one really gets an estimate of $\beta$ and... $\log\alpha$, so one should have a sense of how badly this uncertainty propagates to $\alpha$ (one variable first-order Taylor series: easy peasy). Mary Brock works as an Immunology scientist by day and takes care of a pink-loving princess child by night. Furthermore, it requires and even further on course than calculus (thus more investment of time). Genius! Here in California, the UC system decided ca. Just because the FDA may have its head up its ass does not mean that we have to – yet. Next, mandatory testing of the law of gravity prior to each aircraft flight. Does this mean that future military officers have nothing to gain from learning ancient Greek, or that future dentists have nothing to gain from taking calculus? Integral Calculus joins (integrates) the small pieces together to find how much there is. But this one, gender reveal parties, is the first to parenting trend to lead to a …. It’s worth noting that both Calculus AB and Calculus BC are designed to be comparable to college-level calculus classes. It looks like a great course, though ambitious for first-year students. Calculus is used to determine drug sensitivity as a drugs sensitivity is the derivative of its strength Optimization is used to find the dosage that will provide the maximum sensitivity and strength of a drug Integration can be used to calculate the side effects of drugs such as temperature changes in … The other main goal of the course is to get them able to deal with some (ordinary) differential equations. For example, my wife studied the movement of cells under various circumstances. (If you are not laughing your ass off right now, you may have slept through math class too many times.) Any model involving a reasonably simple relation between variables would work here: calculus is used mostly to deal with uncertainties, and to discuss change of variables and log-log plots. Finding some high end peculiar research justification is not the same as finding a rationale for expending time (which IS a constrained variable. There's also something called XX male syndrome. Click here to upload your image Postdoc: no actual calculus used, but calculus helpful for understanding diffusion of molecules in space, complex numbers, matrices, eigenvalues, Leslie model, elements of one-and higher dimensional calculus (very quickly, mostly through examples), differential equations (mostly geometric theory with phase diagrams on computer), Lotka-Volterra model. It is a bit awkward for me, but I do not find the English files only the Hungarian ones on the homepage... Could you add a link to it anyhow? @MattF. I mean seriously, it is getting pretty absurd right now. Zoologists find that physics plays a role in their animal studies. I have been around for a while, and know how things change, more or less. Applications of calculus to probability and statistics? $$ On the other hand, that may well be a record. The fact that biology students will work with data does not mean they need to use the equation for the normal curve or attempt to integrate it! For example, biology majors learn about the reproduction of ferns and club mosses, which is likely to be of very little practical utility to an optometrist. If you're an artilleryman in an army, you want your artillery shells to hit the enemy, or else theirs may hit you and kill you (game over). There is no need to confirm this with experimental data any more than there is need to confirm that if you take two beans and add two more beans, you have four beans* before you can use arithmetic in a scientific paper. I'm an old-school biologist (animal physiology) who works with mostly cell biologists. One other comment; Tai’s paper was published in a journal with impact factor of 8.1, and has been cited by many many others. Calculus is the study of how things change. will this subject help me as a veterinarian? Sorry, I didn’t mean to put the exact same copy of my question 3 times. This leads to a not-so-easy differential equation of the form fits between a Brownian motion ($\beta=\frac12$) What can calculus add to that? The test covers four areas: physics, biology, chemistry and verbal reasoning. There’s probably a much better forum out there with a lot better information on pharma regulations, though you do have a public blog and you are in a highly technical field and so kinda voluntarily signed up to be a public intellectual (especially when you post things that bash other intellectuals) and so would hopefully not be posting incorrect information for laymen to read and get the wrong impression. In general, calculus is the engineer’s go-to tool for understanding how a system functions in terms of parameters. In economics, calculus is used to compute marginal cost and marginal revenue, enabling economists to predict maximum profit in a specific setting. Can you get through life in a science career without math? A strong math background means at least a yearlong study of Calculus. Wow. This then interacts with statistics: one can find the linear regression in log-log charts to find estimates for $\alpha$ and $\beta$. $\begingroup$ "Many formulas about these coefficients can be handled by calculus." Topics that require Calculus based mathematical maturity are: These next topics are a little more difficult and require knowledge of PDEs but an advanced undergrad could handle this. Another relative comparison is freshman chem versus freshman calc to bio. To add to what Carl Witthoft writes, I think there's a difference between justifiably not using math because mathematical knowledge isn't appropriate/necessary to understand/solve the problem at hand and not using it out of ignorance, when it could in fact be beneficial. Scary. A complex function, integrated in a minute or so. Whoa, there, buddy! Have you ever found yourself sitting through required college courses, thinking, “I’m a [major] Major, dangit, so why am I sitting through this [seemingly unrelated] class! Absolutely not. Emphasis on understanding through models and examples. That’s a good point, I just randomly stumbled on this post and saw something that didn’t look right, so I commented. There are a couple reasons. The motivating example I chose was offered to me by the chemist of our syllabus meeting. Physical pharmacy: rates of diffusion of various things. Tai, A Mathematical Model for the Determination of Total Area Under Glucose Tolerance and Other Metabolic Curves. Biology: You have both given some very good general advice. i began out a working laptop or pc technological wisdom degree and Calculus a million & 2 have been required. Will They Alter my DNA? As technology advances the field of biological studies, these skill are more and more intertwined. You don't have to be a mathematical genius to study physics, but you do need to know the basics, and college physics classes often use calculus and algebra. Maybe he was being sarcastic and I didn’t pick up on it? \frac{\partial n}{\partial t}=-\nabla\cdot\frac{\partial\mathbf{u}}{\partial t} + \nabla\cdot\nabla\cdot(\mathbf{D(\epsilon)}n) Then weigh a known # of squares. Section 1.1 - Why Study Calculus . Writing in the Wall Street Journal, biologist E. O. Wilson asks if math is necessary for doing great science. This simple model is a great example to show how calculus can be relevant to biology. A common model postulates that the average distance $d$ between two Biology is important to everyday life because it allows humans to better understand their bodies, their resources and potential threats in the environment. It's a normal part of pre-calc courses (going back 60+ years, check out Schaum's for instance). Biology, Chemistry and Other Natural Sciences . Then, you need some algebraic manipulations to transform the resulting equation into the form $y(t) = \dots$. While early statistics classes might seem like just pie charts and standard deviations, classes get more advanced quickly and rely on calculus' insights. Also, why would keeping all of your results be a bad thing? @JimBelk I have removed my downvote and turned into an upvote. Published inÂ 1993Â (yes, in theÂ 20th-fucking-century) in a biology journal. I bet that you would agree that the above statement is the embodiment of absurdity. I believe it is generally required that pre-med students take Calculus 1 and 2 or Stats. I have been around for a while, and know how things … But … I fucking shit you not. ), (H/T to Quora for the link to the math study). But in practice, many phenomena are too complex to be addressed with QM AND are well addressed by empirical rules from organic chemistry or periodic table relationships (for inorganic) or ion packing models for solid state chemistry. I do get the joke, however I find I have to ask what I feel was an obvious question: what’s the function that you’re suggesting they integrate in lieu of this approximation? and its integrals, which are ubiquitous in statistical thinking, will not become natural to them in any other way. More importantly, many bio majors will work in quantitative areas in the life sciences, where data science is key. Most colleges first require the successful completion of algebra, trigonometry, and sometimes, elementary analysis -- also known as precalculus -- in order to enroll in calculus. But apparently there is a new reason: so you don’t waste your time reinventing basic calculus. (I'm not blaming the OP, btw, everyone does it!) She could go far. Ans: If you took AP calculus, you need to take at least one additional semester of mathematics at Columbia. In short though, if you were looking to get into software development, you are right, you likely do not need Calculus, you also don't need a Computer Science degree. but Statistics as well. Works for me…. You also need a strong foundation in chemistry and physics (which require strong math skills). This turns out to work, and this person gets to go down in history for reinventing the wheel. A common model for the kinetics of a chemical reaction it. https://matheducators.stackexchange.com/questions/2060/how-is-calculus-helpful-for-biology-majors/2067#2067, https://matheducators.stackexchange.com/questions/2060/how-is-calculus-helpful-for-biology-majors/2097#2097, https://matheducators.stackexchange.com/questions/2060/how-is-calculus-helpful-for-biology-majors/2126#2126, https://matheducators.stackexchange.com/questions/2060/how-is-calculus-helpful-for-biology-majors/2061#2061, Purely anecdotal, but I knew biology undergrads studying epidemiology were using some models that I never looked into but I presume were differential equations, discrete dynamic systems, or both. https://matheducators.stackexchange.com/questions/2060/how-is-calculus-helpful-for-biology-majors/7206#7206, https://matheducators.stackexchange.com/questions/2060/how-is-calculus-helpful-for-biology-majors/2114#2114, https://matheducators.stackexchange.com/questions/2060/how-is-calculus-helpful-for-biology-majors/3990#3990. Having taught that course a lot, the modeling examples fit nonlinear systems as perfectly as physics examples fit linear systems (and almost everything else in basic calculus). f(n)&=\frac{\lambda c_0}{n_0}n Population growth and density dependence; predation; competition and apparent competition; coexistence mechanisms: niches, spatial and temporal variation; food web concepts and properties; applications. I sent out an email to a bunch of grad students and postdocs I work with. I weep for the future though. My eyes glazed over after your FIRST rant. That the area under a curve can be computed as the limit of successive finer scale approximations based on the sums of the areas of rectangles (or triangles or any other geometric shape) is based on the methods first discovered by Eudoxus and Archimedes (hence the bathtub reference) in the 4th and 3rd centuries BCE. And we did teach the trapezoidal rule! Calculus for Beginners and Artists Chapter 0: Why Study Calculus? $\endgroup$ – darij grinberg Jun 5 '10 at 16:21. From antivax nonsenseÂ to spanking defendersÂ and even the Scourge of the Man-Bun,Â we have skeptically dissected and/or viciously mocked parenting trends and myths for almost seven years now. \frac{dN}{dt}&=N(a-bP)\\ I majored in bio back when I wasn't as serious and I divided my classes into "calculator classes" and the rest. Systems of differential equations? I am not a biologist, and this question asks for the contribution of a biologist, nevertheless I might be contribute about the practice in our university in Budapest. IT WAS A JOKE. I love how nearly every answer to this question that's supportive of biology majors learning calculus comes from someone who either isn't a biologist or no longer does biology -- and then proceeds to list the myriad ways in which practicing biologists (which the answer writer is not one of) will not just benefit from knowing calculus, but will need it (generally supported by: "calculus is the study of change, living … From the University of Arizona course catalog (that link will require some clicking around, sorry): ECOL 447 - Introduction to Theoretical Ecology \frac{\partial\mathbf{u}}{\partial t}=\mathbf{f(u)}+D\nabla^2\mathbf{u} However, if you want to be a top innovator in computing, that's when you want to get that degree. Note that students who opt to study Calc BC and take the BC exam will receive a sub-score showing how they performed in AB Calculus. Interpreting the elimination of a drug given orally from the body by looking at measurements in the blood at different times: the drug goes first into the stomach and then into the bloodstream, so you end up with two coupled DEs (or even three, if some organ or tissue is acting as a reservoir). Grad student: none, other than watching some derivatives and integrals in an engineering-level physics. A link to a page in Hungarian is more useful than no link at all. I'm sure you could find this story online. Calc 1 and calc 2 highly recommended. I'm also curious in what ways a two-semester calculus course could be made more helpful for biology majors. But. Added: Here are some links to Hungarian course materials (at least the literature is in English). My relevant experience is talking with friends and colleagues in professional roles that biology majors often pursue. 2 $\begingroup$ As for the third reason, there is absolutely no necessarity why asymptotics must be included in a discrete maths course. Second semester of calculus may be substituted for by 960:379 or 960:401. You can teach students "What p-values really mean" using the concepts of integration. N_{t+1}=N_tF(N_t)=f(N_t) An all-inclusive neurobiology class, which is normally appropriate for upper-division undergraduates, will present the physiology of excitable membranes. For example, even asking to compute how $d$ changes when $T$ is multiplied by a constant needs to now how to deal with exponents. I would be interested in seeing this worked out in more detail. In fact, I would love to be able to do more quantitative analysis of differential equations, but it is difficult to teach since it quickly goes beyond a few recipes. (Take a look at the number of times this paper has been cited for another laugh–even up through 2013. What has the world come to? The Greeks certainly did more sophisticated things than this with quadrature. Calculus is Recommended. Why would you ever get rid of scientific data? I can find no Pharmacokinetics text that does not use AUC = Area Under the Curve, a Calculus concept if ever there was one. They will take chemistry classes in which understanding rates of change is useful, so: More importantly, many bio majors will work in quantitative areas in the life sciences, where data science is key. This will be super useful to biolgists! \frac{\partial}{\partial t}\int_Vc(\mathbf{x},t)dv=-\int_S\mathbf{J\cdot ds}+\int_Vfdv What You Need to Know About Becoming a Biology Major A biology major studies living organisms’ functions and characteristics. Modeling at this level can be as simple as the Nernst equation for the equilibrium potential of a particular ionic species: http://en.wikipedia.org/wiki/Nernst_equation. Calling it a semantic stop sign doesn’t meant that you aren’t missing the point. It's actually an application of "differential equations" but you will need calculus to "get there.". Mathematics courses encourage analytical thinking in a way that may be helpful for biology majors. I agree with you that there should be a course like “Math for Biology Majors.” In the lab, I use mostly statistics, but there have actually been a few times where I have needed to use advanced algebra (extrapolation or solving for x) and trigonometry. Next thing will be, each lab has to prove with 100 patient samples that the method works, and keep the results on file for the auditors. Tai, A Mathematical Model for the Determination of Total Area Under Glucose Tolerance and Other Metabolic Curves. It’s no wonder the cost per head of healthcare in the US is more than twice that in the rest of the OECD and yet we seem to be hell bent on copying the same regulatory framework. $$\frac{1}{\sigma\sqrt{2\pi}}\Large e^{\Large-(x-\mu)^2/2\sigma^2}$$ If you are a student who has not yet studied Calculus, you might not know that, but for any scientist or journal editor to be unfamiliar with it is unforgivable. Calculus curricula don’t make an awful lot of sense to me. Well, many people understand in an intuitive way what Area under the Curve (AUC) means, without knowing calculus. If you're an artilleryman in an army, you want your artillery shells to hit the enemy, or else theirs may hit you and kill you (game over). It's not obvious to me how to apply calculus to this example, since the derivative $dd/dT$ can't be interpreted as a velocity except perhaps in the case $\beta=1$. Calculus is a intrinsic field of maths and especially in many machine learning algorithms that you cannot think of skipping this course to learn the essence of Data Science. $$y'(t)=\sqrt{y(t)}$$ The derivative is "better division", where you get the speed through the continuum at every instant. As mentioned in some of the other answers, a thorough knowledge of statistics is incredibly useful to students pursuing undergraduate research or those with plans to continue their education, but the aforementioned example is an opportunity for students to directly employ differential equations-based models in the undergraduate biology curriculum. These might not be apparent as things from calculus, but can be part of a calculus curriculum. It is used to create mathematical models in order to arrive into an optimal solution. Could you make your answer more focused and provide evidence on these claims? But do they all also know how restricted boltzman machine works? After all, somebody from the FDA may see this thread. That provides sourcing and credibility. $$, Geographic Spread and Control of Epidemics Unless you were trying to cover up something that was illegal…, And the award for “Missing the Point” goes to…, What was the point I missed? 2) I am not making the extraordinary claim you suggest. (I happen to love math, so taking math classes didn’t bother me. The main point of the course is to get students able to deal with quantitative models. Some years ago I taught a one-semester course on mathematics for pharmacy students. Muahaha NOBODY WILL EVER KNOW! Yes, if you want to study Biology (as a major and career), you need a strong math background. Pro tip: If you hate biology, med school is going to be a frackin' nightmare. For example, in physics, calculus is used in a lot of its concepts. As your example shows, it is just a dream and we should know our place. But now I work in Immunology. For example, are there any courses typically taken by biology majors that involve ideas from calculus? reversible [A][B] <-> [AB]. \frac{\partial I}{\partial t}&=rIS-aI+D\nabla^2I I own the copyright on “reinventing the wheel”. When he said, “each lab has to prove with 100 patient samples that the method works, and keep the results on file for the auditors.” that kinda sounds reasonable if you account for intelligently selecting the 100 samples to test (as in these aren’t random samples, but samples that are deliberately spread out along the spectrum of variation that your hypothesis is testing) and the basic idea that you never ever delete your data since its so easy to store and would be vital to building up the knowledge base of science and so specifying that keeping results (under any circumstances) would be a pain, doesn’t make sense unless you look for other explanations and the only one I was able to come up with is if you’re trying to hide from the legal punishment. I looked at some of the second and third-year prescribed books for the pharmacy degree and they had quite a lot of calculus in them. Data for each quintile, decile and percentile should be stored in separate cohorts. \begin{align} It’s used by loads of industries. Seizing an opportunity, they write up a basic description of integral calculus, and bank on the hope that none of the editors or peer-reviewers will have remembered it well enough to see it as the rehash that it is. Do You Need to Have a Physics, Calculus or Algebra-based Degree to Go to Dental School? How is that going to help get your point across? You can also provide a link from the web. Or do you think people used calculators back then? But this isn't just restricted to Professionals. I wasn’t trying to attack, just trying to clarify something I didn’t understand. Suggests perhaps a course on bioinformatics might use calculus. M.M. If so, what ideas come up? But OK if you say so. Later and in the master/PhD program they can choose specialized courses held by biologists about game theory in ecology and population models (based on Lotka-Volterra type models), disease transition or tumor growth models use heavy ODE theory. How Do They Work? I'm not surprised that the only positive response you found was differential equations modeling. However, calculus is great training for the mind. You could also mention several nearby medical colleges (research it on their websites) and if they require calculus (most do, but the MCAT does not test it. $$, Models for Interacting Populations @ChrisCunningham, you're attacking a straw man. GCSE Biology might also come in useful for intermediate or advanced apprenticeships in animal care, horticulture, veterinary nursing or environmental conservation careers . Other formulas widely applied by researchers under- or overestimated total area under a metabolic curve by a great margin. I suppose the part that really threw me was when you said you completely knew what he was talking about because you work in pharma, which is definitely not pure mathematics, and so would hopefully have its theories verified through the testing of samples (which gets back to my point about having the full spectrum available, instead of developing a miracle pill that works without any prior knowledge of a particular individuals category) and so not verified through mathematics alone, I’m assuming. The books are Mathematical Biology I: An Introduction and Spatial Models and Biomedical Applications by JD Murray and Mathematical Models in Biology by Leah Edelstein-Keshet. So you need to know how to angle your artillerygun and which direction to point it in so that when the shell lands, it blows up your enemy (rather than missing). [It will have more traction to say, you need calculus for titrations or dwell times or the like (made up examples...I really don't think ug bio needs calculus much) than if you mention some research need outside the near term needs of the student. One of the prerequisites for her major was … calculus. IT’S A JOKE. Some algebra for bacterial growth curves. This is a first-order ODE with separable variables. \end{align}, Neural Models of Pattern Formations They will take chemistry classes in which understanding rates of change is useful, so: partial derivatives will help them. “You can’ t really say to a math department, 'You will do this for us.’” Change is coming, however, he said. It's a way of gaining broad knowledge about the world and getting experience in varied intellectual pursuits and ways of thinking. Now I can barely breathe from laughing so hard. Even if your method was corrupted by human errors or you started with incorrect testing procedures, why would you ever get rid of it, especially now that a terabyte of storage is about $100 and labeling what was flawed or what didn’t contribute and what did contribute to your conclusions would be extremely easy? S+E\mathrel{\mathop{\rightleftharpoons}^{k_1}_{k_{-1}}} SE\to P+E (Those of you who’ve taught pre-meds won’t be surprised that most medical researchers seem to have slept through grad-school math.) kinetics of a chemical reaction: Let me just say this: calculus, relative to all other sorts of math, is not that conceptually hard. $\beta\in[\frac12,1]$ is a parameter that measures how the movement Fourier series? I mean, LATIN has SOME use...but I would not defend time spent on it. (Note: there is likely no such formula, and thus I will invent one and call it “Mary’s Postulate.” Muhaha. There are programs which run stats, so while it’s important you understand how the calculations work, and which tests are appropriate for different analyses, it’s not like you are running calculations by hand. So better to have math than not, no matter what way you look at things. ), https://matheducators.stackexchange.com/questions/2060/how-is-calculus-helpful-for-biology-majors/2091#2091. What Are Some Dental Schools that Require Calculus I? I happen to have revised our calculus syllabus for first year biology majors about one year ago (in a French university, for that matter). 1997 to start requiring biology majors to take calculus-based physics.
