cut it twice, still too short. Now, what did i do wrong!
When you want to study carbs, you will need to know a thing or two of fluid dynamics. Like the fluids in gaseous form, and flow when liquid. Bernoulli's law comes to mind, but also flow across weirs and through orifices, both of gasses and liquids. The general gas laws of Boile, and Boile Gay-Lussac would be needed as well.
In addition to that, you will need knowledge of combustion, and how it can be influenced.
In short, you want to have a complete phd in a nutshell. It took me a life time. I wish you good luck on your yourney.

PS
Please do not think my comment is in any way meant negative. gaining knowledge is a wonderful thing. But once on that path, there is no end. The journey itself is the end.
