Can You Paint a Picture with Numbers? or Do You Need an Image?

In 2016, during the Syrian Civil War, statistics about the conflict were everywhere. Thousands of people had been killed. The numbers were reported regularly. And yet, most people barely reacted.

Then a single photo changed everything.

It was the image of Omran Daqneesh, a young boy sitting dazed in an ambulance, face bloody and covered in dust. He wasn’t dead. He wasn’t even seriously injured. But because it was a child, and because it was visual, the world suddenly cared.

You might recall it. Can you also recall if it changed your thoughts about the war?

I remember being annoyed. People had been told about the deaths for months. They knew the scale of the suffering - including children. But they only seemed to care when the image hit their emotions.

This was not a new phenomenon. During the late 1800s, Belgian authorities were brutalising the people of the Congo. Reports were published. Descriptions were circulated. But global outrage only came when photographs appeared. One in particular, showing a father looking at the severed hands and feet of his child, triggered a wave of action. Words and statistics alone had not been enough.
The lesson is clear. If you want people to understand, sometimes you need imagery.

What this means for engineers
At first glance, this might feel like a very human failing that has little to do with engineering. But engineers face the same limitation. Numbers, tables, and percentages do not always trigger our full understanding. We often need to convert them into something more tangible to see their significance.
Good engineers learn to paint those pictures in their mind’s eye.

• What does it actually sound like when the SPL reaches that decibel level at that frequency?
• How would it smell if sewage of concentration x% entered the floodwaters?
• What tissue damage would be done if that voltage caused an electric shock to human skin?

In each case, data is only the starting point. Real understanding comes when you can translate the data into sensory and physical implications.

The challenge for the global engineer
We cannot always wait for the real image, the real sound, or the real smell. Our work depends on imagining those consequences before they occur. That’s how we prevent failure and design better systems.
So here is the challenge: next time you are presented with data, don’t just note the numbers. Take the extra step. Convert them into their physical impact. Hear it, smell it, feel it in your imagination.

If you do, you will have overcome one of the limitations of being human. And you will be closer to becoming a truly global engineer.

And you just might start to sense tragedy well before others.

Give thought now to how often you have only understood the seriousness of a situation after you experienced it in some way. And, based on that, think about if you need to put more conscious effort into using numbers to paint a picture in your mind's eye.
