In a spreadsheet, you have rows and columns. Imagine that you added a third dimension to the spreadsheet; what would you call the field variable of that third dimension?
"Slice".

This might be a weird question, but what would be a good starting point to get into the basics of car technology? For example I would like to know more detailed how a clutch works (other than "It's used for changing gears") or how a turbo improves the performance of a car, without going too deep into the vast details of automotive engineering and physics.
