## Ask Slashdot: Should More Math and Equations Be Used In the Popular Press? 385 385

raque writes

*"The NY Times recently published two op-eds in their Philosophy section, The Stone, discussing how Heisenberg's Uncertainty principle is abused. The second is a followup to the first. The author struggled to make clear his point and left the impression he was creating a strawman argument. In his followup he said he was avoiding equations because he was writing for a general audience. I replied to both articles, asking whether showing some basic equations would have worked better, allowing math to illustrate where metaphors struggled. Now I'm asking the same question to everyone on Slashdot. Would Dr. Callendar have been better off just diving in and dealing with Heisenberg and quantum mechanics using the tools that were developed for it?"*

It might be useful in some areas, but quantum mechanics... is one of the hardest places to start.

To put it another way, even if you introduce some equations for quantum mechanics, you are still going to look like an idiot compared to someone from the field... even someone from the field as it existed in the 1920s.

It might be better to go find experts in the field, and have them write short articles for the general public that are about established but not widely known things.

Or, besides writing down the equation, EXPLAIN the equation. And not just write down what the equation says, but what it means.

Let's take a simple one - E=mc^2.

It says the amount of energy something contains is related to its mass (or the amount of "stuff") it contains. The relation is a big one - it's equal to the speed of light squared, so a tiny amount of mass (stuff) produces a LOT of energy. This equation is fundamental to nuclear physics, including peaceful uses such as nuclear power plants, to destructive uses such as nuclear weapons.

Thus the paragraph put close to the equation helps those who can't read the equation to still understand what it says, and it also explains where it's used and what it means.

But you're correct on the fundamental problem - it's because those in the sciences (and engineering) put little weight on the "arts" side of things (including things like writing) as they believe that stuff is a lot of fluff. (I can't generalize this, but if you ask a lot of people in IT, they seem to look down on studying anything that isn't related to their field - like why should a computer scientist or engineer take courses in philosophy or logic, or take classes in English or writing or even home economics).

Likewise, a lot of people take arts because they want to avoid the math and science.

Which is terrible - and it leads to this gulf of communications problems where journalists (or any writer, really) misinterprets some scientific or technical thing because the writer and the technical person are failing to communicate effectively (a problem on BOTH sides). Or how technical people look upon sales, marketing and PR people with disdain, because those people know how to relate to the public, but often fail to relate to the technical staff.

Perhaps instead of the token math or science class for an arts degree, or the token arts/business class for a technical/science degree, the two should be combined more tightly to produce a more well-rounded person who may be technical, but understands the other side.

In the last 90 years we haven't suddenly become idiots, so if popular science books talking about special/general relativity and quantum theory (a theory 90 years old !!!!) don't use equations it is because of stupid preconceptions.

No, we have a sensationalist and mystery-mongering culture for the same reason we have superstition: fundamental human ignorance, and a failure of the educational system.

We don't expect journalists to write articles only in Basic English [wikipedia.org]. If someone were to profess that they had never heard of Shakespeare, or didn't know what a metaphor was, we would rightly judge them as being ignorant, or at the least, highly under-educated. Yet, apparently, balking at the simplest of equations is perfectly acceptable.

It's no wonder that we have such shallow thinking, such an abysmal and superficial political discourse, such a

The author struggled to make clear his point and left the impression he was creating a strawman argument

Strange - I found his arguments (in the first article, didn't read the second) quite straight forward, and I feel that adding equations would only have obfuscated matters. Most people don't understand equations and inequalities or their specific significance, and that goes for a lot of well-educated people too. The significance of Heisenberg's inequality is that you can use it in quantitative calculations when you test your theory, but it does not in itself add much to your intuitive understanding of the pr

A good book to read on this topic is David Bodanis's E=mc^2,

"A biography of the world's most famous equation"

It's not just another Einstein book. It's actually about just the equation and its life.

The author gives examples of how printing houses using different equation notation were like Microsoft, driving out the competition for the standard.

All manner of symbols were used for math, some examples:

e================== mc^2 .aequs. mc^2

e || mc^2

e -----------> mc^2

e ][ mc^2

You'll make people smarter and able to understand the subject if you explain what's going on in the example you want to discuss. That's a pretty basic idea in writing popular science.

This is what I came here to say, too. The "no-equations" dictum is pretty much an ironclad rule from editors and publishers. The author in question basically has no say in the matter. Which is pretty messed up, in that everyone is required to take basic algebra to communicate in that language, and then it's banned by fiat from our popular media.

Come to think of it, if the tendency for PR firms to arrange for an "equation for the best sandwich" [google.co.uk] etc. suggests that an equation is actually quite an easy way of getting the public's attention.

If the equation look real enough, people will just zone out, or worse, assume that the author opinion must be true since there is a formula.

One should bother because pandering to the lowest denominator will ensure that most will meet that expectation.

There is a range of happy media between a wall of mathematical formulae and proofs and an awkwardly written, purely textual interpretation. Not everyone will have a full (or even good) comprehension of the meaning, but those willing to be challenged will have something on which to proceed.

You can write about the results - which is important - but you can't write about the mechanics without at least describing the mathematical concepts and their relations with physical reality. This is why it's such a problem, because everyone deduces from the results written up in the newspapers how they think the mechanics work, and of course they get it wrong because it's profoundly unintuitive.

You can't write about quantum mechanics without equations - it is NOT an intuitive field.

Betteridge's Law of Headlines says no.

And at least in this particular case, "no" is indeed the correct answer. Equations can never be a substitute for actual understanding. You can use equations to develop understanding by starting from an earlier point and transform the initial equation to establish a new fact. But where do you start with quantum mechanics? "Quantum states are being represented by rays in a complex Hilbert space"?

If anything, equations can be used to create an argumentum ad auctoritatem, and I'm not sure that this is a good thing.
