From the age of eight, I had huge fun building models. The sense of achievement I had when they occasionally worked is amongst my most treasured memories.
They ranged from cranes to aeroplanes, models of famous buildings, or, on one occasion, a mechanical contraption for passing written messages across the ceiling of my classroom. Amazingly, it was a long time before my teacher tumbled to what we were doing in class.
I once made a radio amplifier from cheap components. I turned on the power, there was a humming noise, and blue smoke filled the dining room! Nearly all my models initially ended in failure. Failure is very important because if we use it properly, we learn from our mistakes and rebuild
with great improvement. All scientists encounter failure regularly; only by embracing it do we eventually get our experiments to work.
Modelling is really important, especially for scientists, engineers, and architects. Nobody would dream of designing a structure like a bridge or a stadium without making models first.
This helps them understand the science behind the structures, the mathematical principles involved, and how recalculation may be needed to achieve their final ambition. Even the simplest experiments in this book show how modelling can help resolve practical problems.
