I'm learning a new programming language based on graphics. There is a program called LabVIEW that is used here at NASA to collect and evaluate data from wind tunnel tests. I'll try to explain it as best I can. When you click on an arrow that runs the program, the sum of those two numbers appears in the box. It's basically like connecting wires in real life, only it's on a screen.
Uncertainty is a very important thing to keep in mind when dealing with scientific data of any sort.
When you get a reading from a machine, you want to know that the information you are getting is actually the information you are seeking. For instance, if you were seeing how fast a person could ride on a bike, you wouldn't just take their speed no matter what the situation was and say that you had accurate data. The wind and the slope of the hill would be sources of uncertainty in this case, because they make it difficult to tell what the person's actual riding ability is. This program I am working on will allow different sources of uncertainty to be put into the Wright Flyer data, so we can see how the data we actually got might have been affected by such things. Since the AIAA is actually trying to build a replica that will fly, it is crucial to be as careful as possible when figuring out what the data obtained during the NASA wind tunnel test represents.
