Why drawing isn’t just an art
There's a growing understanding that drawing is much more than an art form: it's a powerful tool for learning.
- We often think of drawing as something that takes innate talent, but this kind of thinking stems from our misclassification of drawing as, primarily, an art form rather than a tool for learning.
- Researchers, teachers, and artists are starting to see how drawing can positively impact a wide variety of skills and disciplines.
- Drawing is not an innate gift; rather, it can be taught and developed. Doing so helps people to perceive the world more accurately, remember facts better, and understand their world from a new perspective.
Most of us have spent some time drawing before, at the very least because of compulsory art classes. It's also likely that you've scribbled curlicues in the margins of your notes during some particularly boring lecture about how the mitochondria is the powerhouse of the cell or how to graph linear equations.
But at some point, most of us stop drawing. There are people who don't, obviously, and thank god for that: a world without designers and artists would be a very shabby one indeed. But the vast majority of adults quit doodling when they quit having to take notes, and the closest they get to making something visually creative is applying a wacky font in a PowerPoint presentation.
But some argue that so many adults have abandoned drawing is because we've miscategorized it and given it a very narrow definition. In his book, Stick Figures: Drawing as a Human Practice, Professor D.B. Dowd argues that "We have misfiled the significance of drawing because we see it as a professional skill instead of a personal capacity. This essential confusion has stunted our understanding of drawing and kept it from being seen as a tool for learning above all else."
Dowd argues that we mistakenly think of "good" drawings as those which work as recreations of the real world, as realistic illusions. Rather, drawing should be recategorized as a symbolic tool. In an interview with Print Magazine, Dowd said:
Drawing is an ancient human activity, practiced by all persons. How do I get to the airport? Pretend your phone is dead, so forget GPS. Anyone trying to answer that question is likely to say, "Here, let me show you…" and grab a pencil and an envelope to scribble on. That's drawing! We use it all the time. Explain the rules of hockey. Describe geology. Help me understand "The Mason-Dixon Line." These things have to be manifested visually.
The cortical homunculus has body proportions based on how many nerve endings there are in the relevant body part. Notice how large (and therefore how sensitive) the hands are; this is because humans are built to handle subtle tools, like pens and pencils.
Human beings have been drawing for 73,000 years. It's an inextricable part of what it means to be human. We don't have the strength of chimpanzees because we've given up brute strength to manipulate subtle instruments, like hammers, spears, and — later — pens and pencils. The human hand is an extremely dense network of nerve endings; the somatosensory homunculus (a sculpture of a human being where the body proportions correspond to how sensitive the associated nerve networks are) demonstrates this well. In many ways, human beings are built to draw.
In fact, doodling has been shown to affect how the brain runs and processes information in a significant way. Some researchers argue that doodling activates the brain's so-called default circuit — essentially, the areas of the brain responsible for maintaining a baseline level of activity in the absence of other stimuli. Because of this, some believe that doodling during a boring lecture can help students pay attention.
Evidence has shown that doodling does actually improve memory. In one study, participants were asked to listen to a list of names while either doodling or sitting still. Those who doodled remembered 29 percent more of the names than those who did not.
Darwin's sketches of finches were crucial to illustrate his theory of evolution
It's not just absent-minded, abstract doodling that helps the brain either; drawing concepts and physical objects forces your brain to engage with a subject in new and different ways, enhancing your understanding. For example, some researchers tested study participants' ability to recall a list of words based on whether they had copied the word by hand or drawn the concept — like writing the word "apple" versus drawing one. The drawers often were able to recall twice as many words.
There's also evidence that drawing talent is based on how accurately someone perceives the world. The human visual system tends to misjudge size, shape, color, and angles but artists perceive these qualities more accurately than non-artists. Cultivating drawing talent can become an essential tool to improve people's observational skills in fields where the visual is important.
In biology, for example, describing and categorizing the shape and form of living things is critical. Prior to the invention of the photograph, biologists were trained draftsmen; they had to be in order to show the world the details of a new species. Now, some biology professors are reintroducing physical drawing in their biology courses. The reasoning is that actively deciding to draw helps people see the world better.
Rather than think of drawing as a talent that some creative people are gifted in, we should consider it as a tool for seeing and understanding the world better — one that just so happens to double as an art form. Both absent-minded doodling and copying from life have been shown to positively affect your memory and visual perception, so raise hell the next time your school board slashes the art department's budget.

What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
It's a "canary in the coalmine," said one climate scientist.
- A team of researchers discovered that permafrost in Northern Canada is melting at unusually fast rates.
- This could causes dangerous and costly erosion, and it's likely speeding up climate change because thawing permafrost releases heat-trapping gasses into the atmosphere.
- This week, Canada's House of Commons declared a national climate emergency.
One of Stephen Hawking's predictions seems to have been borne out in a man-made "black hole".
- Stephen Hawking predicted virtual particles splitting in two from the gravitational pull of black holes.
- Black holes, he also said, would eventually evaporate due to the absorption of negatively charged virtual particles.
- A scientist has built a black hole analogue based on sound instead of light.
Not every part of a satellite burns up in reentry. Considering the growing number of satellites in orbital space, that's a big problem.
- Earth's orbital space is getting more crowded by the day.
- The more satellites and space junk we put into orbit, the greater a risk that there could be a collision.
- Not all materials burn up during reentry; that's why scientists need to stress test satellite parts to ensure that they won't become deadly falling objects.
