The most disturbing thing I learnt this week was that IMAGINARY numbers land your plane. Nope, I’m not kidding. They use IMAGINARY numbers. This doesn’t sound particularly reassuring. I’m just glad that I didn’t find this out whilst sitting in a plane approaching a runway. That wouldn’t have made me feel very comfortable.
Now I’m not in a position to explain anything about imaginary numbers, real numbers are something that I’m not completely au fait with at the best of the times. It appears to be an abstract concept to deal with sums that the clever boffins want answers to but that real numbers won’t let them get there. Or something. I just remember seeing i + i = -1. Scary stuff. Then they applied it to landing planes. Big huge planes. Full of people planes.
Maths quickly takes on an aura of black magic to me. I can do four basic functions. With a calculator. I can even attempt percentages. With a calculator. It still means precious little to me. It just SCARES me. And that was before it all became make believe.
