Devil captured Physicist, Engineer and Mathematician. He gave each of them big can of spam and locked them in the empty room saying „you will be here for 2 weeks - open the can and survive or die to starvation”. After 2 weeks Devil opens Physicist cell. It’s covered floor to the ceiling in complex scribbles. One piece of wall is clean of etching but small dent is visible. Can of span is opened and eaten clean, Physicist sits in corner visibly annoyed. Next one is Engineer. Cell walls are covered in multiple dents and pieces of spam. Engineer is bruised almost as much as the can, but it is ultimately opened and engineer is alive.
Finally the Devil opens Mathematician cell and find him dead. Only „given the cylinder” is etched on the wall.

Puent isn’t about engineering but it always helped me to set limits between software engineering and computer science.
